Safety and efficiency of COVID-19 vaccine in North Africa

Background In the absence of a specific treatment for COVID-19, preventive measures have been implemented to control this pandemic and vaccination is one of them. However, it is crucial to verify the safety and efficiency of every vaccine. The aim was to determinate the predictive factors of side effects and reinfection after COVID-19 vaccine. Methods A cross-sectional study was conducted in February 2022 among Tunisians infected with COVID-19 between March 2020 and February 2022, using an online self-administered questionnaire. We conducted univariate and multivariate analyses using binary stepwise logistic regression. Results A total of 1541 was selected from 1911 individuals. Comorbidities affected a quarter of the population (22.3%). Before the initial infection, 39.3% had received full vaccination, and 8.7% had received partial vaccination. By February 2022, the majority (82.9%) had received at least two vaccine doses. The reinfection rate was 30.6%. All vaccines prior to the first infection was identified as a protective factor against reinfection. Inactivated virus vaccinations were less likely to induce adverse effects. Conclusion ach vaccine has its own set of advantages and disadvantages: mRNA-based vaccines had a higher incidence of side effects but all vaccines provided better protection against reinfection.

Self-Thermal Management in Filtered Selenium-Terminated MXene Films for Flexible Safe Batteries

Li-ion batteries with superior interior thermal management are crucial to prevent thermal runaway and ensure safe, long-lasting operation at high temperatures or during rapid discharging and charging. Typically, such thermal management is achieved by focusing on the separator and electrolyte. Here, the study introduces a Se-terminated MXene free-standing electrode with exceptional electrical conductivity and low infrared emissivity, synergistically combining high-rate capacity with reduced heat radiation for safe, large, and fast Li+ storage. This is achieved through a one-step organic Lewis acid-assisted gas-phase reaction and vacuum filtration. The Se-terminated Nb2Se2C outperformed conventional disordered O/OH/F-terminated materials, enhancing Li+-storage capacity by ≈1.5 times in the fifth cycle (221 mAh·g-1 at 1 A·g-1) and improving mid-infrared adsorption with low thermal radiation. These benefits result from its superior electrical conductivity, excellent structural stability, and high permittivity in the infrared region. Calculations further reveal that increased permittivity and conductivity along the z-direction can reduce heat radiation from electrodes. This work highlights the potential of surface groups-terminated layered material-based free-standing flexible electrodes with self-thermal management ability for safe, fast energy storage.

Earthquake in Turkey: The Triangle of Life and Disaster Kits Saves Lives

OBJECTIVE

Precautions taken before an earthquake are of vital importance. When buildings collapse, the weight of the ceiling crushes objects such as furniture, leaving a space or void within the rubble. This area is called the "triangle of life." The larger and stronger the object, the more it will maintain its volume; the more the object maintains its volume, the larger the void will be, and the less likely it is that the person who uses this void will be injured.

METHODS

Durable, solid furniture such as beds and tables that can be tipped over during an earthquake in appropriate areas in the building can form a living triangle. Creating and using the triangle of life is the method of protection in an earthquake that produces the highest probability of survival.

RESULTS

Two earthquakes with magnitudes of 7.8 and 7.5 occurred in Kahramanmaraş, Turkey, on February 6, 2023. This report presents the case of a 43-y-old female victim of these earthquakes who used the triangle of life to survive; she was removed from the rubble 164 h after the earthquake.

CONCLUSIONS

The case provides evidence that predetermining areas in which the triangle of life can be formed and storing supplies necessary for survival can decrease morbidity and mortality in an earthquake.

The Digital Therapeutics Real-World Evidence Framework: An Approach for Guiding Evidence-Based Digital Therapeutics Design, Development, Testing, and Monitoring

Digital therapeutics (DTx) are a promising way to provide safe, effective, accessible, sustainable, scalable, and equitable approaches to advance individual and population health. However, developing and deploying DTx is inherently complex in that DTx includes multiple interacting components, such as tools to support activities like medication adherence, health behavior goal-setting or self-monitoring, and algorithms that adapt the provision of these according to individual needs that may change over time. While myriad frameworks exist for different phases of DTx development, no single framework exists to guide evidence production for DTx across its full life cycle, from initial DTx development to long-term use. To fill this gap, we propose the DTx real-world evidence (RWE) framework as a pragmatic, iterative, milestone-driven approach for developing DTx. The DTx RWE framework is derived from the 4-phase development model used for behavioral interventions, but it includes key adaptations that are specific to the unique characteristics of DTx. To ensure the highest level of fidelity to the needs of users, the framework also incorporates real-world data (RWD) across the entire life cycle of DTx development and use. The DTx RWE framework is intended for any group interested in developing and deploying DTx in real-world contexts, including those in industry, health care, public health, and academia. Moreover, entities that fund research that supports the development of DTx and agencies that regulate DTx might find the DTx RWE framework useful as they endeavor to improve how DTxcan advance individual and population health.

Attuning to the World of Peace of Mind and Trust: Women's Lived Experience of the Woman-Midwife Relationship in Japan

In Japan, many pregnant women and mothers suffer from anxiety, depression, and other postnatal issues that can be exacerbated by their birth experiences. While benefiting from advanced medical care, these women's mental and psychological health may be disregarded in their maternity care. Midwives have the potential to play a significant role in improving women's birth experiences. Hence, this study aimed to explore the meaning of the woman-midwife relationship, with a specific focus on sensing peace of mind and trust to improve women's birth experiences. Using a hermeneutic phenomenological approach, 14 Japanese women were interviewed. Sensing peace of mind and trust was one of the significant meanings of the woman-midwife relationship and is articulated across five themes: (1) attuning to the world, (2) different kinds of safety and trust, (3) relying on and entrusting midwives, (4) making a mother, and (5) an emotional bridge. The positive relationship with midwives enhanced the women's mental well-being through allowing the women to attune to the peaceful mind which directed their future perspectives and sustained them in motherhood. They became confident mothers by trusting their midwives. The maternity care system in Japan needs to shift to more relationship-based care to ensure continuity of midwifery care that will improve women's birth experiences and their long-term well-being.

The range, rank, control flow and source of risk, as well as the control measures are determined. The standard extracts the underlying common problems and basic requirement of the safe practice of acupuncture so as to lay a framework for the development of the relevant technical standards of acupuncture.

Acceptability of a Hypothetical Reduction in Routinely Scheduled Clinic Visits Among Patients With History of a Localized Melanoma (MEL-SELF): Pilot Randomized Clinical Trial

BACKGROUND

After treatment for a localized melanoma, patients attend routinely scheduled clinics to monitor for new primary or recurrent melanoma. Patient-led surveillance (skin self-examination with patient-performed teledermoscopy) is an alternative model of follow-up that could replace some routinely scheduled visits.

OBJECTIVE

This study aims to assess the acceptability of a hypothetical reduction in routinely scheduled visits among participants of the Melanoma Self Surveillance (MEL-SELF) pilot randomized clinical trial of patient-led surveillance (intervention) versus usual care (control).

METHODS

Patients previously treated for localized melanoma in New South Wales who were participating in the MEL-SELF pilot randomized clinical trial were asked to respond to a web-based questionnaire at baseline and after 6 months on trial. We used mixed methods to analyze the data. The main outcome of interest was the acceptability of a hypothetical reduction in routinely scheduled visits for melanoma surveillance.

RESULTS

Of 100 randomized participants, 87 answered the questionnaire at baseline, 66 answered the questionnaire at 6 months, and 79 provided a free-text explanation at either time point. At 6 months, 33% (17/51) of the control group and 35% (17/49) of the intervention group indicated that a hypothetical reduction in routinely scheduled visits with all melanoma doctors was at least slightly acceptable (difference in proportions -1%, 95% CI -20% to 17%; P=.89). Participants suggested that prerequisites for a reduction in routinely scheduled visits would include that sufficient time had elapsed since the previous diagnosis without a new primary melanoma or recurrence, an unscheduled appointment could be made at short notice if the patient noticed something concerning, their melanoma doctor had suggested reducing their clinic visit frequency, and patients had confidence that patient-led surveillance was a safe and effective alternative. Participants suggested that a reduction in routinely scheduled visits would not be acceptable where they perceived a very high risk of new or recurrent melanoma, low self-efficacy in skin self-examination and in the use of technologies for the patient-led surveillance intervention, and where they had a preference for clinician-led surveillance. Some patients said that a partial reduction to once a year may be acceptable.

CONCLUSIONS

Some patients may be receptive to a reduction in routinely scheduled visits if they are assured that patient-led surveillance is safe and effective.

The Efficacy and Safety of Imusil® Tablets in the Treatment of Adult Patients With Mild COVID-19: A Prospective, Randomized, Multicenter, Open-Label Study

Introduction Coronavirus disease 2019 (COVID-19) is a serious concern of the new era. Along with antiviral synthetic medications, there is a need to discover efficacious herbal antiviral medicines with minimum side effects in patients against COVID-19. This study aimed to assess the efficacy and safety of Imusil® among patients with mild COVID-19. Methods A prospective, randomized, multicenter, open-label, interventional study was conducted in patients with mild COVID-19 infection. Patients received either Imusil one tablet four times a day (seven days) along with the standard of care (SoC) or only SoC. The study endpoints were reverse transcription-polymerase chain reaction (RT-PCR) negativity, changes in cycle threshold (CT), clinical improvement, change in blood inflammatory indexes, and safety assessment. Results A total of 100 patients were enrolled, and 98 received at least one dose of treatment. The median age of patients was 36.0 years, and 58 were males. By day 4, 85.4% of patients in the Imusil+SoC group tested negative for RT-PCR compared to 64% of patients exhibiting the same outcome in the SoC group (P=0.0156). After eight days, clinical improvement was observed in all patients from the Imusil+SoC group, while in the SoC group, clinical improvement was observed in 94.0% of patients (P=0.4947). During follow-up visits, the average C-reactive protein (CRP) levels decreased from baseline in both treatment groups. The decrease in the levels of CRP (-7.3 mg/dL versus -5.5 mg/dL), D-dimer (-231.0 ng/mL versus -151.6 ng/mL), and interleukin 6 (IL-6) (-2.3 pg/mL versus -2.0 pg/mL) at eight days was comparatively higher in the Imusil+SoC group versus the SoC group. There were no serious treatment-emergent adverse events in the drug arm. Conclusion Imusil provides effective antiviral activity and safety in mild COVID-19 patients. Imusil ensures faster RT-PCR negativity and clinical improvement and ensures effective reduction of inflammatory markers such as CRP, D-dimer and interleukin 6.

Botulinum toxin injection is an effective alternative for the treatment of chronic anal fissure

OBJECTIVES

There are few published data on the optimized use of botulinum toxin A (BTA) for the treatment of chronic anal fissure (CAF). The aim of this study was to investigate the effect of injection of 100 IU BTA into the internal anal sphincter (IAS) at the side opposite of the fissure, using an anal retractor, sedation, and perianal transcutaneous pudendal nerve block.

METHODS

The prospectively maintained data of 132 patients who underwent BTA injection for CAF were retrospectively analyzed. Demographic data, symptom duration, fissure location, post-procedure pain, complications, continence status, response to treatment, and follow-up period were investigated. Postoperative analgesic requirements of patients who did and did not receive pudendal nerve block were compared.

RESULTS

Eighty-two patients were male and the median age was 40 (18-74) years. Sixty-six patients required no, 46 required oral, and 20 required parenteral analgesics. No complications were observed. Complete response was observed in 105 patients (79.5%). Symptomatic improvement was observed in 67.4% of patients within 3-7 d. Median follow-up was 24 (18-42) months. The median Wexner's incontinence score was 0 (0-8) at 1 month. In all, 104 patients had no, 22 patients had minor, and 6 patients had non-minor incontinence. All patients with incontinence recovered fully within 4 (2-13) weeks.

CONCLUSIONS

BTA injection using an anal retractor under sedation and perianal transcutaneous pudendal nerve block is an effective and safe alternative to partial lateral internal sphincterotomy (LIS) for the treatment of CAF.

Application of the robot-assisted implantation in deep brain stimulation

INTRODUCTION

This work aims to assess the accuracy of robotic assistance guided by a videometric tracker in deep brain stimulation (DBS).

METHODS

We retrospectively reviewed a total of 30 DBS electrode implantations, assisted by the Remebot robotic system, with a novel frameless videometric registration workflow. Then we selected 30 PD patients who used stereotactic frame surgery to implant electrodes during the same period. For each electrode, accuracy was assessed using radial and axial error.

RESULTS

The average radial error of the robot-assisted electrode implantation was 1.28 ± 0.36 mm, and the average axial error was 1.20 ± 0.40 mm. No deaths or associated hemorrhages, infections or poor incision healing occurred.

CONCLUSION

Robot-assisted implantation guided by a videometric tracker is accurate and safe.

Future perspective safe cosmetics: Focused on associated with ISO natural organic index

BACKGROUND

As we enter the era of long COVID, recent studies on the relationship between coronavirus disease-19 (COVID-19) and skin are being conducted from various angles. Awareness of the safety of healthy skin is increasing.

OBJECTIVES

Therefore, in this study, we empirically analyzed safe cosmetics, natural cosmetics, and organic cosmetics, which have recently become a critical issue.

METHODS

Keywords such as 'long COVID', 'COVID-19 Skin', 'ISO Natural Organic Index', 'edible', 'safe cosmetics', 'natural cosmetics', and 'organic cosmetics' were searched and created. This study was conducted using PubMed, Google Scholar, Riss, Scopus, and ResearchGate. Accordingly, a total of 689 papers were studied. This paper was successfully completed using a total of 41 references in this study using PRISMA flow diagram.

RESULTS

In the long COVID era, customers in the beauty and cosmetics market will have to apply ISO natural organic ingredients to the cosmetics and beauty industry, reflecting consumer demand for edible ingredients for safety issues. Therefore, it will be able to provide new strategy and implications for a safer cosmetic market that values health and beauty.

CONCLUSION

Therefore, in this literature review, interest in skin has increased due to the long corona, and it was determined that changes in the cosmetic market would be necessary by using the ISO natural organic index for the consumer's desire for healthy skin. Therefore, in this article, in the future development of eco-friendly organic cosmetics, in line with the natural and environment-friendly changes reminiscent of the efficacy or ingredients of products, it is necessary to develop cosmetics using the ISO natural organic index that meets the needs of consumers and a differentiated strategy.

Recombinant African Swine Fever Virus Arm/07/CBM/c2 Lacking CD2v and A238L Is Attenuated and Protects Pigs against Virulent Korean Paju Strain

African swine fever (ASF) is an obligated declaration swine disease, provoking farm isolation measures and the closing of affected country boarders. ASF virus (ASFV) is currently the cause of a pandemic across China and Eurasia. By the end of 2019, ASF was detected in nine EU Member States: Bulgaria, Romania, Slovakia, Estonia, Hungary, Latvia, Lithuania, Poland and Belgium. The affected area of the EU extended progressively, moving mostly in a southwestern direction (EFSA). Inactivated and/or subunit vaccines have proven to fail since certain virus replication is needed for protection. LAVs are thus the most realistic option, which must be safe, effective and industrially scalable. We here generated a vaccine prototype from the Arm/07/CBM/c2 genotype II strain, in which we have deleted the EP402R (CD2v) and A238L genes by CRISPR/Cas9 in COS-1 cells, without detectable further genetic changes. The successful immunization of pigs has proven this vaccine to be safe and fully protective against the circulating Korean Paju genotype II strain, opening the possibility of a new vaccine on the market in the near future.

Catheter ablation of atrial fibrillation in patients with heart failure and preserved ejection fraction: A meta-analysis

Background

Catheter ablation (CA) is an effective treatment for patients with atrial fibrillation (AF). The potential of CA to benefit AF patients with heart failure and preserved ejection fraction (HFpEF) is uncertain.

Hypothesis

CA may be safe and effective for patients with HFpEF.

Methods

The Medline, PubMed, Embase, and Cochrane Library databases were searched for studies evaluating CA for AF patients with HFpEF.

Results

A total of seven trials with 1696 patients were included. Pooled analyses demonstrated similar procedure and fluoroscopy time regarding the use of CA for patients with HFpEF and without HF (weighted mean difference [WMD]: 0.40; 95% confidence interval (CI): −0.01–0.81, p = .05 and [WMD: 0.05; 95% CI: −0.18–0.28, p = .68]). Moreover, CA was effective in maintaining sinus rhythm (SR) in patients with HFpEF and noninferior for patients without HF [risk ratio (RR): 0.92; 95% CI: 0.76–1.10, p = .34). Additionally, CA tended to significantly maintain SR (RR: 4.73; 95% CI: 1.86–12.03, p = .001) and reduce rehospitalization for HF compared with medical therapy (RR: 0.36; 95% CI: 0.19–0.71, p = .003). However, no significant differences were found between two groups regarding the mortality rate (p = .59).

Conclusion

CA is a potential treatment strategy for patients with HFpEF and demonstrates equivalent efficacy to that of patients without HF. Moreover, the benefits of CA in maintaining SR and reducing rehospitalization of HF patients were significantly better than those of medical therapy. Additional randomized controlled trials are warranted to confirm our results.

Research on Applications of Transurethral Plasmakinetic Enucleation of the Prostate in Elderly Patients Aged ≥80 Years

Objective: To evaluate the safety and efficacy of transurethral plasmakinetic enucleation of the prostate (PKERP) vs. transurethral resection of the prostate (TURP) in elderly patients aged ≥80 years with benign prostate hyperplasia. Materials and Methods: We conducted a retrospective analysis of the PKERP (n = 123) and TURP (n = 143) in patients aged ≥80 years at urology department of The Third Xiangya Hospital of Central South University from January 2016 to October 2019. Then the preoperative, intraoperative, and postoperative data of different indicators were compared between the two groups. The follow-up was done at 3 months, 1 year after surgical treatment. Results: No significant differences were observed between the two groups for the baseline characteristics, including age, prostate volume, prostate-specific antigen (PSA) level, concurrent disease, maximum urinary flow rate (MFR), international prostate symptoms score (IPSS), and quality of life (QoL) score. The operative time, hemoglobin decrease, and postoperative flushing time were significantly lower in the PKERP group compared with the TURP group. However, no significant differences were observed between both groups for postoperative hospital stay, incidence of transurethral resection syndrome (TURS), prostatic capsular perforation, and genuine urinary incontinence. The follow-up results showed that the MFR of the PKERP group was significantly higher than the TURP group at 1 year after surgery. Conclusion: Compared with TURP, PKERP is a safe and efficacious method for treating patients aged ≥80 years with benign prostate hyperplasia, and it may improve long-term urination symptoms.

Removal of Broken Cannulated Drill Bit

Breaking of surgical drill bits and subsequent dislodging in the bone are quite common in the field of orthopedics. Even though a few methods have been reported to remove dislodged drill bits, we present a novel method to remove a broken drill bit without additional instruments or a secondary incision. A broken cannulated drill bit within the locking screw hole inside the neck of a femur was retrieved using a depth gauge with a curved tip that hooked onto the edge of the drill bit. By employing a clockwise and counter-clockwise twisting, the broken drill bit was retrieved through the proximal reaming tract. The 4mm tract, which was established by proximal reaming, immensely facilitated safe and time-efficient removal of the drill tip without further trauma or prolonging the surgery time. With our technique, the removal was simple and safe without further soft tissue trauma and blood loss. We advocate this approach for implementation in similar cases.

Endoscopic Endonasal Transsphenoidal Approach for the Surgical Treatment of Pituitary Apoplexy and Clinical Outcomes

Purpose: This study investigated the clinical manifestations, surgical method, and treatment outcomes of patients with pituitary apoplexy and evaluated the safety and effectiveness of the endoscopic endonasal transsphenoidal approach in the treatment of pituitary adenomas. Patients and methods: In this retrospective study, were analyzed the data of patients with symptomatic pituitary apoplexy who received surgical treatment by endoscopic endonasal transsphenoidal approach from January 2017 to June 2020 at the Department of Neurosurgery of the First Affiliated Hospital of Bengbu Medical College. Patients were followed up through outpatient visits and telephone interviews. Results: Data for 24 patients including 13 males and 11 females with an average age of 46.46 years were analyzed. Headache (83.33%) and visual disturbances (75.00%) were the most common preoperative manifestations. In the 24 patients, 21 (87.50%) tumors were completely removed and 3 (12.50%) were partly removed. Intractable headache improved in all patients over a mean follow-up time of 25.16 months, and postoperative improvement in visual acuity was achieved in 17 of 18 patients (94.44%) with vision defects. Four patients (16.67%) experienced transient urinary collapse after the operation. No intracranial infection, carotid artery injury, or death occurred. Conclusion: The endoscopic endonasal transsphenoidal approach is a safe and effective method for the treatment of pituitary apoplexy.

People Who Chose the Preventive Natural Bioenergetics (NB) COVID-19 Treatment Safely Experienced a Significant Reduction of COVID-19 Symptoms Compared to the General Population

BACKGROUND AND AIM

The aim of this study is to assess if people who chose to receive the preventive Natural Bioenergetics (NB) COVID-19 treatment would experience safely a strong reduction in frequency and severity of COVID-19 major symptoms (fever, cough, and shortness of breath) compared to the general population. Experimental procedure: The preventive NB COVID-19 treatment is a double acupuncture meridian-based procedure that primes the immune system using acupuncture points and specific substances and sounds on precise body locations. Four hundred and thirty-nine people from seven countries (Canada, USA, Mexico, UK, France, Israel, and Belgium) voluntarily received the non-invasive preventive NB treatment. Data used for this study have been gathered between April 2020 and December 2020. The severity of cases experienced by the general population was statistically compared with those of the 42 infected people of this study.

RESULTS AND CONCLUSION

Our analysis suggests the population who chose to receive the preventive NB COVID-19 treatment experienced a strong reduction in frequency and severity of the three major symptoms of COVID-19 (p<0.01) compared to the general population. Nobody in that population needed hospitalization, including the elderly, which can be interpreted as a very significant clinical improvement. Most people did not report any side effects. Only small side effects were reported.

A nephroprotective iodinated contrast agent with cardioprotective properties: A pilot study

BACKGROUND AND PURPOSE

Evaluation and treatment of acute ischemic syndromes, in the heart and brain, require vessel visualization by iodinated X-ray contrast agents. However, these contrast agents can induce injury, in both the kidneys and target organs themselves. Sulfobutylether beta cyclodextrin (SBECD) added to iohexol (SBECD-iohexol) (Captisol Enabled-iohexol, Ligand Pharmaceuticals, Inc, San Diego, CA) is currently in clinical trials in cardiovascular procedures, to determine its relative renal safety in high-risk patients. Preclinical studies showed that SBECD-iohexol reduced contrast-induced acute kidney injury in rodent models by blocking apoptosis. The current study was undertaken to determine whether SBECD-iohexol is also cardioprotective, in the male rat ischemia-reperfusion model, compared to iohexol alone.

METHODS

After anesthesia, the left coronary artery was ligated for 30 min and the ligation released and reperfusion followed for 2 h prior to sacrifice. Groups 1-4 were injected in the tail vein 10 min prior to ischemia with: (1) vehicle; (2) iohexol; (3) SBECD; and (4) SBECD-iohexol. Infarct size, hemodynamics, and serum markers were measured.

RESULTS

An eight-fold increase in serum creatine kinase in the iohexol-alone group was observed, compared with no increase in the SBECD-iohexol group. The mean arterial pressure and rate pressure product were depressed in the iohexol-alone group, but not in the SBECD-iohexol group, or controls. No difference in infarct size or serum creatinine among the groups was observed.

CONCLUSION

The results of this study suggest that SBECD-iohexol is superior to iohexol alone, for both the preservation of cardiomyocyte integrity and preservation of myocardial function in myocardial ischemia.

Efficacy and Safety of Radiofrequency Ablation for Breast Cancer Smaller Than 2 cm: A Systematic Review and Meta-Analysis

Background

To evaluate the efficacy and safety of radiofrequency ablation (RFA) of breast cancer smaller than 2 cm.

Methods

A systematic search was conducted in the PubMed and EMBASE databases to identify published studies investigating the efficacy and safety of RFA for breast cancer smaller than 2 cm. The main outcomes were technical success rate of the ablation, complete ablation rate, complications and local recurrence. Secondary considerations were mode of anesthesia, pain tolerance, mean ablation time and surgical excision after ablation.

Results

Seventeen studies involving 399 patients and 401 lesions met the inclusion criteria. Nearly 99%(95%CI=0.98-1.00) of lesions achieved good technical success rate.Notably, 83.88% of the patients received RFA under general anesthesia (333/397) whereas 15.87% received RFA under local anesthesia (63/397). Of the 63, 98.41% tolerated the pain associated with the procedure. Majority of patients (65.74%, 261/397) underwent surgical excision of the tumor after ablation whereas in a few patients (34.26%, 136/397), the tumor tissue was retained in the breast after ablation. Complete ablation was achieved in 96% of patients for a mean time of 15.8 minutes (95%CI=0.93-0.99). Overall, only 2% (95%CI=0.01-0.04) of the individuals developed complications. Skin burns (2.02%, 8/397) were the most common complications. There was no local recurrence after a median follow-up of 27.29 months, whether or not they underwent surgical resection following RFA.

Conclusion

The results show that RFA for breast cancer smaller than 2 cm is safe and effective. However, prospective studies are needed to validate this conclusion.

Tone From the Top: The Role of the General Counsel in the Prevention of Harassment and Abuse in International Sports

To prevent harassment and abuse in sports, the consensus is that an essential factor is “tone from the top” of the organization. It is key as a catalyst and sustainer of change, whether in the corporate or sports world. An organization's general counsel is one of the go-to top advisors for executive leadership regarding laws and regulations. Additionally, they serve as advisors for issues in other areas, such as public policy, ethical and legal risks, and human rights. With their leadership, general counsels can play a vital role in the prevention of harassment and abuse in an organization. The guidance and leadership of the general counsel should facilitate reviewing and strengthening of the organization's policies and procedures and other strategies helping to prevent and address issues of harassment and abuse. Legal issues become more complex the more global the organization, so more complex strategies are needed to tackle these issues successfully.

Balloon-Assisted Coils Embolization for Ophthalmic Segment Aneurysms of the Internal Carotid Artery

Objective: To explore the role of balloon-assisted coils technique for ophthalmic segment aneurysms (OSAS).

Methods: Clinical data of 30 patients with OSAS were reviewed between December 2017 and December 2018. OSAS were defined as arising from the internal carotid artery (ICA), reaching from the distal dural ring to the origin of the posterior communicating artery. OSAS were classified into four types based on the angiographic findings. The balloon-assisted coils technique was used for the embolization of aneurysms. The duration of balloon inflation cycles, as well as difficulty and complications during the embolization procedure, were recorded. The immediate angiographic results were evaluated according to the Raymond scale. Clinical results were evaluated based on the MRS score. Follow-ups were performed at 18 months post-embolization by DSA or MRA at our institution.

Results: Thirty-two aneurysms in 30 patients were detected by digital subtraction angiography (DSA), which included 30 unruptured and two ruptured cases. The patients with ruptured aneurysms were grade II status according to the Hunt-Hess scale. Three cases were type A, nine cases were type B, 17 cases were type C, and three cases were type D. According to aneurysm size, there were 19 cases of small, 11 cases of medium, two cases of large aneurysm. Thirty-two aneurysms were successfully embolized in 30 patients by balloon-assisted coils technique. The ophthalmic artery could be protected by an engorged balloon in the procedure, especially for type A aneurysms. Considering that type D aneurysm arises from the side-wall of the artery and near to tortuous ICA siphon, the balloon catheter was inflated to stabilize the microcatheter allowing for overinflation when necessary. The average duration of balloon dilatation was 4 min, and the average time was 2.5 times. Raymond class was one in 28 aneurysms and two in four aneurysms according to the immediate post-embolization angiographic results. All the patients achieved good clinical effects, except for one patient who presented with brain ischemia resulting in dizziness and contralateral limb weakness for 10 h due to prolonged temporary clamping of the responsible ICA. The follow-up angiography results were satisfactory at 18 months post-embolization.

Conclusion: OSAS endovascular treatment with balloon-assisted coils has different advantages in a different classification. The technique is safe, effective, and relatively inexpensive, especially for small and medium OSAS.

Subacute and subchronic toxicity of microencapsulated pomegranate juice in rats and mice

Pomegranate (Punica granatum L.) is a fruit used extensively in traditional medicine by ancient and modern cultures. Different parts of the tree and fruit, such as leaf, peel, pericarp, aril, seed, and juice contain considerable amounts of phenolic compounds with high antioxidant activities. To improve its storability, pomegranate juice was microencapsulated by spray drying. The present study evaluated microencapsulated pomegranate juice (MPJ) for toxic effects in Wistar rats and CD-1 mice to determine if MPJ can be considered safe for human consumption and used as a nutraceutical. No deaths or deleterious effects occurred when high doses of 5000 mg/kg were orally administered in rats for 14 days, indicating an absence of subacute toxicity. Similarly, 3000 mg/kg MPJ administered to CD-1 mice for 90 days did not show subchronic toxicity. In fact, MPJ resulted in lowered weight gain in both rats and mice. Cytotoxic and microbiological analyses of MPJ were also performed. MPJ did not cause any cytotoxicity in epithelial cell culture as tested using the Alamar blue assay. Additionally, histopathological analysis of kidney and liver corroborated the absence of toxicity in CD-1 mice. The microbial load of the MPJ was low, and no pathogenic bacteria were present. In conclusion, the results reported here show that high doses of MPJ are apparently innocuous in rats and mice for the 14 and 90 days investigated, respectively. Although preliminary, our results suggest that MPJ may be safe to ingest and may even have beneficial effects in reducing weight gain.

The safety of modern intravenous iron infusions in patients with rheumatoid arthritis - a review of the literature

Objectives: To assess the evidence for the safety of intravenous iron infusions in patients with rheumatoid arthritis.Methods: A systematic literature search was performed in June 2019 on PubMed and Cochrane databases for eligible studies.Results: There is significant evidence of safety and efficacy of intravenous iron in patients with rheumatoid arthritis using newer, less immunogenic iron preparations, such as iron sucrose and low molecular weight iron dextran preparations.Discussion: Iron deficiency anaemia has a significant impact on the quality of life of patients with rheumatoid arthritis, but the use of intravenous iron is generally avoided due to concerns raisedin older studies using high molecular weight iron dextran of exacerbating the disease. However, such concerns have not been confirmed in more recent studies using newer preparations.Conclusion: We find significant evidence of safety and efficacy in more recent studies of larger cohorts of patients using newer, less immunogenic iron preparations.

[Pharmacovigilance of traditional Chinese medicine according to theory of preventive treatment of disease]

&quot;Preventive treatment of disease&quot; is one of the characteristics and advantages of traditional Chinese medicine. It is the most influential theory of traditional Chinese medicine. The core of the theory is &quot;pre-prevention before disease&quot;, &quot;prevention of disease from progress&quot; and &quot;prevention of recovery after disease&quot;, and the prevention concepts are &quot;prevention of disease from deve-lopment&quot; and &quot;blockage and reversal&quot;. Based on the analysis of large numbers of ancient books, we put forward the overall pharmacovigilance theoretical frame that is composed of toxicity cognition, application, prevention and detoxification. With rich prospective prevention, the pharmacovigilance theory of traditional Chinese medicine was the essence of drug use experience in China for thousands of years. It coincides with the idea of preventing disease with precautions and preventing the occurrence of drug-induced diseases. This article intends to consider the theory and practice of pharmacovigilance of Chinese medicine from the &quot;preventive treatment of disease&quot;, in order to provide reference for clinical safety medication. It has puts forward the practical measures of pharmacovigilance of traditional Chinese medicine, such as giving medical advice, paying attention to monitoring, preventing biological change, planning for the long term, preventing disease from changing, delaying the disease progress, protecting vital Qi, controlling internal disorder and preventing recurrence. It also indicated that pharmacovigilance of traditional Chinese medicine is an important part of the &quot;preventive treatment of disease&quot;, and an important guarantee for the safe and rational use of medicines in clinical practice, which is conducive to protecting and promoting people&apos;s health and improving people&apos;s quality of life.

Outcomes and adverse effects of ablative vs nonablative lasers for skin resurfacing: A systematic review of 1093 patients

It is generally believed that ablative laser therapies result in prolonged healing and greater adverse events when compared with nonablative lasers for skin resurfacing. To evaluate the efficacy of ablative laser use for skin resurfacing and adverse events as a consequence of treatment in comparison to other modalities, a PRISMA-compliant systematic review (Systematic Review Registration Number: 204016) of twelve electronic databases was conducted for the terms "ablative laser" and "skin resurfacing" from March 2002 until July 2020. Studies included meta-analyses, randomized control trials, cohort studies, and case reports to facilitate evaluation of the data. All articles were evaluated for bias. The search strategy produced 34 studies. Of 1093 patients included in the studies of interest, adverse events were reported in a total of 106 patients (9.7%). Higher rates of adverse events were described in nonablative therapies (12.2% ± 2.19%, 31 events) when compared with ablative therapy (8.28% ± 2.46%, 81 events). 147 patients (13.4%) reported no side effects, 68 (6.22%) reported expected, transient self-resolving events, and five (0.046%) presented with hypertrophic scarring. Excluding transient events, ablative lasers had fewer complications overall when compared with nonablative lasers (2.56% ± 2.19% vs 7.48% ± 3.29%). This systematic review suggests ablative laser use for skin resurfacing is a safe and effective modality to treat a range of pathologies from photodamage and acne scars to hidradenitis suppurativa and posttraumatic scarring from basal cell carcinoma excision. Further studies are needed, but these results suggest that ablative lasers are a superior, safe, and effective modality to treat damaged skin.

Safe, mild ultraviolet-B exposure: An essential human requirement for vitamin D and other vital bodily parameter adequacy: A review

The enigma of skin sunburning, skin ageing and skin cancer and essential vitamin D production both resulting from solar ultraviolet‐B (280‐315 nm) (UVB) exposure has long puzzled photobiologists. Advice to patients by non‐photobiological clinicians is now often to sunbathe to acquire vitamin D adequacy. However, modern work shows only mild UVB exposure is needed to maintain satisfactory levels, which have been demonstrated as very similar in summer and winter from about 25° to 70° north. Even very careful high protection factor 15 sunscreen use does not prevent adequate production, although it is slightly reduced, such that obsessive use of very protective screens of 50 + might. Dark skin pigmentation too usually at most minimally impairs production. However, confinement indoors and widespread clothing cover can, but oral supplementation overcomes any such deficiency. Thus, vitamin D adequacy needs just mild regular UVB skin exposure well under sunburning levels, unlikely to cause significant skin damage. This suggests mild UVB exposure may also be needed for other bodily requirements, which is indeed so. Thus, it also prevents the development of contact dermatitis and polymorphic light eruption through suppressing adaptive immunity. It also prevents the occurrence of multiple skin infections resulting from this suppression through stimulating innate immunity and cutaneous bacterial defensin production. Finally, blood pressure is reduced through low‐dose UVB‐induced production of the vasodilator nitric oxide (though UVA, 315‐400 nm, is more efficient). Thus, mild UVB exposure is important for several aspects of internal health, whereas high‐dose exposure is extremely detrimental to cutaneous health.

Eliminating Trachoma by 2020: Assessing Progress in Nigeria

Trachoma is a neglected tropical disease that causes an eye infection which can lead to blindness if left untreated. In 1998, the World Health Organisation (WHO) launched a new goal to eradicate trachoma by 2020. Over the years, in partnership with the WHO, an effective strategy plan was devised to help tackle and control the disease. This involved surgery for trichiasis, antibiotic treatment, facial cleanliness, and environmental improvement (SAFE). Consequently, the number of people affected by trachoma has significantly decreased in recent times. Despite this, trachoma remains a major public health concern in 44 countries worldwide, including Nigeria. Although improvements have been seen throughout Nigeria, the disjointed application of the SAFE strategy has delayed progress compared to other countries. Providing quality treatment to those with trachoma, in addition to improving preventative measures are challenges faced throughout the country. However, a multi-pronged approach emulating the methods of other countries is recommended to achieve trachoma elimination. This review aims to evaluate the progress and challenges faced in Nigeria with regards to eliminating trachoma.

The infection rate of intralesional triamcinolone and the safety of compounding in dermatology for intradermal and subcutaneous injection: A retrospective medical record review

BACKGROUND

Intralesional injection of sterile medications remains a mainstay in dermatology, enabling a tailored, low-cost, in-office therapy. After the 2012 United States outbreak of fungal meningitis from contaminated intrathecally administered corticosteroids, there has been increased regulation of in-office compounding, regardless of the administration route. Studies demonstrating the safety data of in-office corticosteroid compounding for intradermal or subcutaneous use are lacking.

OBJECTIVE

To assess the incidence of infection caused by compounded in-office intralesional triamcinolone.

METHODS

A retrospective medical record review identified patients who received in-office intralesional corticosteroid injections in 2016. Medical documentation within 30 days of injection was reviewed for suspected infection.

RESULTS

The records of 4370 intralesional triamcinolone injections were assessed, of which 2780 (64%) were compounded triamcinolone with bacteriostatic saline. We identified 11 (0.25%) suspected localized infections, with 4 of the 11 in the compounding cohort. Of these, 7 of 11 occurred after injection of an "inflamed cyst." No hospitalizations or deaths occurred. No temporal or locational relationships were identified.

LIMITATIONS

This study was limited to 2 academic institutions. A 30-day postinjection time frame was used.

CONCLUSION

In-office compounding for intralesional dermal and subcutaneous administration is safe when sterile products are used by medical practitioners. There is no increased risk of compounded triamcinolone relative to noncompounded triamcinolone.

Safe clinical practice in pre-licensure nursing students: A concept analysis

The aim of this paper is to provide a concept analysis for safe clinical practice for pre-licensure nursing students. Safe clinical practice is crucial to creating a safe environment. Defining the concept of safe clinical practice is important. Walker and Avant's concept analysis approach was used. Cumulative index to Nursing and Allied Health, Business Source Elite, Education Resources Information Center, and PsycINFO were searched for literature on safe clinical practice. The key words "student," "safety," "performance," and "unsafe student" were used. From a review of the literature, defining attributes, antecedents, and consequences of safe clinical practice were established and a definition of the concept emerged. The defining attributes identified are knowledge, skills, individual accountability, and professionalism. Students demonstrating appropriate knowledge levels and good technique with skills contribute to safe clinical practice. Taking accountability for one's actions and being professional also are important attributes to maintaining a safe clinical environment and ensuring safe clinical practice. Safe clinical practice in a patient-student situation occurs when pre-licensure nursing students who have been adequately prepared and practicing within a safe environment demonstrate knowledge of the clinical situation and its risks; communicate with faculty and staff members professionally; and develop appropriate relationships.

N-Acetylation of Amines in Continuous-Flow with Acetonitrile-No Need for Hazardous and Toxic Carboxylic Acid Derivatives

A continuous-flow acetylation reaction was developed, applying cheap and safe reagent, acetonitrile as acetylation agent and alumina as catalyst. The method developed utilizes milder reagent than those used conventionally. The reaction was tested on various aromatic and aliphatic amines with good conversion. The catalyst showed excellent reusability and a scale-up was also carried out. Furthermore, a drug substance (paracetamol) was also synthesized with good conversion and yield.

A Review of Salivary Diagnostics and Its Potential Implication in Detection of Covid-19

Saliva is an exocrine secretion produced from the salivary glands and has numerous functions, such as cleansing and protection of the oral cavity, antimicrobial effects and aids in digestion. Due to the speedy development in the field of salivaomics, saliva is now well accepted as a pool of biological markers that vary from changes in biochemicals, nucleic acids and proteins to the microflora. Saliva has an immense potential as a diagnostic fluid and offers an edge over other biological fluids as its collection method does not require invasive procedure, economical and is useful for monitoring systemic health. Development of sensitive and precise salivary diagnostic tools and the formulation of defined guidelines following meticulous testing will allow salivary diagnostics to be utilised as chair side tests for various oral and systemic diseases in the near future. The coronavirus disease (Covid-19) pandemic is the biggest challenge and global health crisis for the world since World War Two. Rapid and accurate diagnosis of Covid-19 is crucial in controlling the outbreak in the community and in hospitals. Nasopharyngeal and oropharyngeal swabs are the recommended specimen types for Covid-19 diagnostic testing. The collection of these specimen types requires close contact between healthcare workers and patients and poses a risk of transmission of the virus, causes discomfort and may cause bleeding, especially in patients with condition such as thrombocytopenia. Hence, nasopharyngeal or oropharyngeal swabs are not desirable for sequential monitoring of viral load. Saliva specimens can be obtained easily as the patient is asked to spit into a sterile bottle. The collection of saliva is non-invasive and greatly minimizes the exposure of healthcare workers to Covid-19. Saliva has a high consistency rate of greater than 90% with nasopharyngeal specimens in the detection of respiratory viruses, including coronaviruses. Saliva has also been used in screening respiratory viruses among hospitalized patients without pyrexia or respiratory symptoms. SARS-CoV can be detected in saliva at high titers. Salivary diagnostics is a dynamic field that is being incorporated as part of disease diagnosis, clinical monitoring of systemic health and to make significant clinical decisions for patient care. More research is required to analyze the potential diagnostic of Covid-19 in saliva to develop rapid chair side tests for the detection of Covid-19 and it is also pivotal to improve and develop successful strategies for prevention, especially for dentists and healthcare professionals who are involved in performing aerosol-generating procedures.

A Case of Toxicity from Cannabidiol Gummy Ingestion

A 56-year-old male with no known history of substance abuse and no known prior medical conditions presented via ambulance to the emergency department after being found by coworkers with bizarre behavior, vomiting, and slurred speech. He had legally purchased cannabidiol (CBD) gummies marketed for pain and anxiety relief at a gas station several hours prior. Vitals upon arrival were temperature 36.8 Celsius, heart rate (HR) 79, respiratory rate (RR) 12, blood pressure (BP) 113/60, and oxygen saturation (O₂) of 84% on room air that improved upon arousal. Physical exam showed an obese man in no acute distress with a depressed level of consciousness but who awoke to painful stimuli. Neuro exam was significant for dysarthric, hypophonic speech. Labs were significant for a primary respiratory acidosis with concomitant mild lactic acid elevation, normal bicarbonate, and normal anion gap. A comprehensive urine toxicology screen including cannabis was negative. Vital signs three hours after presentation deteriorated, showing: HR 47, RR 8-12, BP 88/52, O₂ 78%. Electrocardiogram (EKG) revealed sinus bradycardia. The patient progressively became more obtunded and required constant stimuli in order to maintain a patent airway. Non-invasive positive pressure ventilation was not administered due to persistent emesis. The patient underwent supportive care with intravenous fluids, oxygen, anti-emetics, continuous stimulation, and close neurologic monitoring with full recovery by the following morning. Further, patient history revealed that he had consumed two packages of CBD gummies, totaling 370 mg total of CBD (serving size on the package was 30 mg). He felt the products were healthy and safe based on packaging and therefore did not believe they would have any adverse effects. CBD is one of many cannabinoids found in marijuana and marijuana-derived products. It is generally considered safe unlike its more psychoactive counterpart, tetrahydrocannabinol (THC), which has been linked to seizures, respiratory depression, and cardiovascular complications. CBD has surged in popularity recently, being marketed in oils, capsules, and candies as a health supplement, claiming to treat a wide variety of medical conditions such as glaucoma, pain, and even having beneficial effects on cancer prevention. Most currently available studies do not look at isolated CBD nor their synthetic equivalents, and purity is not guaranteed, thus leading to unforeseen side effects and toxicities. Moreover, these compounds do not show on traditional toxicology screens, posing a diagnostic dilemma for physicians. This case of respiratory depression and cardiovascular compromise in a relatively healthy man is just one example of the importance of considering synthetic CBD toxicity in the differential diagnosis, as there is little data available for recognizing and treating this condition.

Building Safe Didactic Dialogues for Action Model: Mobilizing Community with Micronesian Islanders

Background: Despite mandates by the United States (U.S.) government to ensure the inclusion of women and minorities in federally funded research, communities of color continue to participate less frequently than non-Latinx Whites. There is limited research that examines maternal health outcomes and early childhood resources. Pacific Islanders (PI) have grown substantially in a county in the Pacific Northwest region of the U.S. (from 4,419 to 9,248, of which 52% are female). About 62.7% of PI women are not accessing prenatal care in the first trimester, and this is substantially higher than the national target of 22.1%. Researchers found that PI children are leaving school to take care of family obligations. The purpose of the educational innovative project, Building Safe Didactic Dialogues for Action model, was to respond to Micronesian Islanders (MI) parent leaders' need to feel safe and to build a close kinship to encourage dialogue about difficult topics regarding access and utilization of early education systems and prenatal/perinatal health for community-driven model for action planning and solutions. Approach: Popular education tenets were used in the project to be culturally sensitive to the human experience. The MI community health worker outreached to MI parent leaders in an urban area in the Pacific Northwest region of the U.S. Eight partners participated in this project: parent leaders from the MI community-at-large, community partners from the MI Community organization, and academic nurse researchers. Didactic dialogues lasted two hours per session for four. Topics included: collaborative agreements, MI parent leaders' identified needs and existing resources regarding preschool and immunization, parent-child relationship (stress and trauma, adverse childhood experiences), and MI experience regarding prenatal care access and postpartum depression. Group discussion on reflection was used to evaluate utility. Outcomes: Building Safe Didactic Dialogues for Action model was foundational via mobilizing community with MI, trust and rapport building, and engaging in a safe and courageous space for dialogues for action planning and solutions as community and academic partners as stakeholders. Conclusion: Many previously unspoken issues such as abuse, language, and cultural beliefs including barriers were openly shared among all partners. Dynamic thoughts towards identifying needs for change and then planning steps toward creating positive change created an atmosphere of empowerment for change.

Development and implementation of electronic medical handovers across psychiatric hospitals: quality improvement initiative

A lack of integration between internal processes and failure to use the full potential of information technology (IT) systems is common in psychiatric hospitals. We aimed to reduce the number of out-of-hours medical errors by ensuring that there is consistent and transparent weekend medical handover by creating an electronic handover system that is easy to use, robust and embedded into the existing trust IT systems. We employed quality improvement (QI) methodology to address this issue. After trialling in a single site followed by six cycles of improvement, the weekend medical handover system is now in use across four boroughs and has been integrated into trust policy. It has received qualitative and quantitative evidence of improvement, with 100% of doctors reporting the system improved patient care and a 64% (from 11 to 4 events/year) reduction in moderate, severe and catastrophic adverse incidents occurring out-of-hours within the older adult service (p=0.29, χ² 1.117). The increasing number of complex patients with comorbid medical illness in psychiatric inpatient services demands robust handover systems similar to that of an acute trust. This QI work offers a template for achieving this across other psychiatric trusts and demonstrates the positive change that can be achieved.

Safe and highly efficient adaptation of potentially explosive azide chemistry involved in the synthesis of Tamiflu using continuous-flow technology

Tamiflu is one of the most effective anti-influenza drugs, which is currently manufactured by Hoffmann-La Roche from shikimic acid. Owing to its importance, more than 60 synthetic routes have been developed to date, however, most of the synthetic routes utilise the potentially hazardous azide chemistry making them not green, thus not amenable to easy scale up. Consequently, this study exclusively demonstrated safe and efficient handling of potentially explosive azide chemistry involved in a proposed Tamiflu route by taking advantage of the continuous-flow technology. The azide intermediates were safely synthesised in full conversions and >89% isolated yields.

Inhibition of cortical neural networks using infrared laser

The aim of the present study is to optimize parameters for inhibiting neuronal activity safely and investigating thermal inhibition of rat cortex neural networks in vitro by continuous infrared (IR) laser. Rat cortex neurons were cultured on multi-electrode arrays until neural networks were formed with spontaneous neural activity. Neurons were then irradiated to inhibit the activity of the networks using different powers of 1550 nm IR laser light. A finite element heating model, calibrated by the open glass pipette method, was used to calculate temperature increases at different laser irradiation intensities. A damage signal ratio (DSR) was evaluated to avoid excessive heating that may damage cells. The DSR predicted that cortex neurons should be safe at temperatures up to 49.6°C for 30 seconds, but experiments suggested that cortex neurons should not be exposed to temperatures over 46°C for 30 seconds. Neural response experiments showed that the inhibition of neural activity is temperature dependent. The normal neural activity could be inhibited safely with an inhibition degree up to 80% and induced epileptiform activity could be suppressed. These results show that continuous IR laser radiations provide a possible way to safely inhibit the neural network activity.

[Meta-analysis on efficacy and safety of combination therapy of Aconitum and Western medicine in treatment of rheumatoid arthritis]

To analyze the efficacy and safety of the combination therapy of Aconitum and Western medicine in the treatment of rheumatoid arthritis (RA) by Meta-analysis, and provide evidence for its clinic application for RA. The random clinical trials (RCTs) regarding the combination therapy for treating RA were retrieved in the database of China National Knowledge Infrastructure database, China Science and Technology Journal database, WanFang, Chinese Biomedical Medical Database, PubMed, and Cochrane Library up to July 2017. According to the given inclusion criteria, 8 RCTs involving 659 participants were included, and the included RCTs could be further divided into three subgroups according to the herb type, which were Aconiti Radix (Chuanwu) subgroup (6RCTs), Aconiti Kusnezoffii Radix (Caowu) subgroup (1RCT), and Chuanwu-Caowu subgroup (1RCT). The Meta-analysis results indicated that as compared with Western medicine, the combined use of Aconitum and Western medicine, no matter Chuanwu, Caowu or Chuanwu-Caowu subgroups, could improve the total effective rate of RA (6RCTs, RR=1.19, 95%CI [1.10, 1.28], P<0.000 01), (1 RCT, RR=1.43, 95%CI [1.18, 1.73], P=0.000 2), (1 RCT, RR=1.27, 95%CI [1.02, 1.58], P=0.03) respectively. The combined use of Aconitum and Western medicine was also effective on the number of joint swelling, duration of morning stiffness, patients' handgrip, and the erythrocyte sedimentation rate, C-reactive protein and rheumatoid factor. However, its action was not significant on joint tenderness. And also, in the included RCTs, there were 34 cases of adverse drug reactions/events (ADR/ADE) in the Chuanwu subgroup, while 86 cases in the Western medicine control group. The ADR/ADE incidence was even more lower in Chuanwu-Caowu subgroup, but no difference between Caowu subgroup and Western medicine group. Based on the included RCTs, the combined use of Aconitum and Western medicine could achieve more satisfying efficacy and lower ADRs incidence for RA as compared with Western medicine alone. However, due to the limitation in the not-high quality of included RCTs and the lack of large-scale multi-center research, the results still need to be further validated in the clinic application.

Creation of Novel Toxic Gas Surrogates and the Development of Safe and Facile Catalytic Reactions

The use of toxic gas surrogates in organic reactions instead of the gas itself contributes to enhancing the safety, practicality, and efficiency of the reactions involved. Our efforts toward the creation of toxic gas surrogates and the development of a series of catalytic reactions using these surrogates are described. Improvements in substrate scope during the hydroesterification of alkenes using formates facilitated by the Ru-imidazole catalyst system provided the opportunity to discover that phenyl formate is a useful carbon monoxide (CO) surrogate for the generation of CO and phenol under weakly basic conditions. This discovery triggered the development of highly reactive but stable CO surrogates and a variety of Pd-catalyzed carbonylative transformations. N-Formylsaccharin facilitated the use of additional nucleophiles in carbonylation reactions that provided access to a variety of carbonyl compounds. Detailed experimental and theoretical mechanistic studies into the generation of CO from phenyl formate suggest that CO generation proceeds via a concerted E2 α-elimination. Furthermore, a known surrogate of sulfur dioxide was applied for the first time to the selective syntheses of cyclic sulfonamides and sulfinamides, confirming that the surrogate operates as an "S=O" source. Notably, the reactions described herein are scalable and can be performed without the use of external toxic gases and specialized reaction vessels; they are easy and simple to perform and demonstrate enormous potential for industrial application.

Development of a Topical Resveratrol Formulation for Commercial Applications Using Dendrimer Nanotechnology

Resveratrol (RSV) is well known for its anti-oxidant and anti-aging properties. However, resveratrol is insoluble in water and has stability issues. Recently, efforts were placed to prepare a resveratrol-based advanced anti-aging topical product but it contains harsh organic solvents and oils that could be harmful to the human body and the environment. Hence, we propose the use of a multifunctional dendrimer to solve the solubility and stability issues of resveratrol. A dendrimer-resveratrol complex was prepared, optimized and tested for solubility enhancement, stability in solution and cream dosage forms. We have also developed a high performance liquid chromatography method to measure the resveratrol within the final product. PAMAM dendrimers increased the solubility and stability of resveratrol in water and semisolid dosage forms. Therefore, this product would be water based 'green' formulation devoid of harsh organic solvents and oils and can be safely applied to the skin. Additionally, we have shown that the dendrimer helped to increase overall RSV loading and skin penetration of resveratrol. The dendrimer-RSV formulation was successfully scaled up towards commercialization. Dendrimer with RSV has led to an innovation in anti-aging cream and solutions that could be commercially marketed. Dendrimer-RSV complex could also be added to other product forms for additional purposes and applications.

Safe Use of Subcutaneous Diphenhydramine in the Inpatient Hospice Unit

BACKGROUND

Diphenhydramine (DPH) is most commonly used via oral, topical, intramuscular (IM) and intravenous (IV) routes for the palliation of pruritus, treatment of extrapyramidal symptoms, management of parkinsonism and for allergic reactions. However, many hospice patients are unable to take oral medications and/or do not have IV access. Moreover, topical administration has a relatively slow rate of absorption. For this reason, in the hospice setting it is not uncommon for diphenhydramine to be administered via the subcutaneous (SC) route secondary to its ease of access, low infection rates and its low levels of discomfort. In contrast, outside the hospice setting, subcutaneous DPH has not been widely used, primarily because of a handful of case reports published in the 1990's that report skin necrosis following subcutaneous administration of DPH for local anesthesia. Since these early case reports, however, there has been very little in the way of research to examine this further. The aim of this study is to provide objective data concerning the safe use of subcutaneous diphenhydramine, as part of our efforts to improve upon safe practices in our organization.

METHODS

This is a retrospective review of records from 6 of our inpatient hospice units obtained from our pharmacy database for patients who received at least one subcutaneous injection of diphenhydramine between 2012-2015. Selected patients were then subsequently screened for post-administration skin necrosis, as recorded in our quality assurance database during the same time period.

RESULTS

A total of 648 diphenhydramine subcutaneous injections were administered in109 individual patients. None of the patients were reported to have an adverse cutaneous reaction.

CONCLUSIONS

This retrospective review demonstrates that subcutaneous diphenhydramine injection is a safe alternative to oral and other parenteral routes, and may be particularly valuable in terminally ill patients, who are often unable to swallow and are without IV access.

Effectiveness, durability, and safety of darunavir/ritonavir in HIV-1-infected patients in routine clinical practice in Italy: a postauthorization noninterventional study

Current antiretroviral (ARV) therapy for the treatment of human immunodeficiency virus (HIV-1)-infected patients provides long-term control of viral load (VL). Darunavir (DRV) is a nonpeptidomimetic protease inhibitor approved for use with a ritonavir booster (DRV/r). This study evaluated the effectiveness of DRV/r in combination with other ARV agents in routine clinical practice in Italy. In this descriptive observational study, data on utilization of DRV/r, under the conditions described in the marketing authorization, were collected from June 2009 to December 2012. Effectiveness (VL <50 copies/mL), tolerability, and durability in four patient groups (two DRV/r-experienced, one ARV-experienced DRV/r-naïve, and one ARV-naïve) were analyzed. Secondary objectives included immunological response, safety, and persistence/discontinuation rates. In total, 875 of 883 enrolled patients were included in the analysis: of these, 662 (75.7%) completed the follow-up until the end of 2012 and 213 (24.3%) withdrew from the study earlier. Initial DRV dose was 600 mg twice daily (67.1%) or 800 mg once daily (32.9%). Only 16 patients (1.8%) withdrew from the study due to virological failure. Virological response proportions were higher in patients virologically suppressed at study entry versus patients with baseline VL ≥50 copies/mL in each ARV-experienced group, while there was no consistent difference across study groups and baseline VL strata according to baseline CD4⁺ cell count. CD4⁺ cell count increased from study entry to last study visit in all the four groups. DRV/r was well tolerated, with few discontinuations due to study-emergent nonfatal adverse events (3.0% overall, including 2.1% drug-related) or deaths (3.0% overall, all non-drug-related); 35.3% of patients reported ≥1 adverse events. These observational data show that DRV/r was effective and well tolerated in the whole patient population described here. The DRV/r-containing regimen provided viral suppression in a high percentage of patients in all groups, with low rates of discontinuation due to virological failure.

Intravenous levetiracetam in critically ill children

Background:

To report the effectiveness and safety of intravenous (IV) levetiracetam (LEV) in the treatment of critically ill children with acute repetitive seizures and status epilepticus (SE) in a children's hospital.

Materials and Methods:

We retrospectively analyzed data from children treated with IV LEV.

Results:

The mean age of the 108 children was 69.39 ± 46.14 months (1-192 months). There were 58 (53.1%) males and 50 (46.8%) females. LEV load dose was 28.33 ± 4.60 mg/kg/dose (10-40 mg/kg). Out of these 108 patients, LEV terminated seizures in 79 (73.1%). No serious adverse effects were observed but agitation and aggression were developed in two patients, and mild erythematous rash and urticaria developed in one patient.

Conclusion:

Antiepileptic treatment of critically ill children with IV LEV seems to be effective and safe. Further study is needed to elucidate the role of IV LEV in critically ill children.

Exposure assessment for chemical and physical agents

Exposure assessment to either chemical or physical agents, as applicable, is a necessary step for both etiologic diagnosis of occupational disease and health surveillance of workers. The assessment can be carried out by measurements of concentrations in air of the substance by either fixed or personal samplers. The former give an indication of the general environment, the latter, applied near the mouth of the worker, provide personalized information. Dermal exposure (deposition) and absorption occur in the occupational setting, but their measurement is so complex that there are no routine methods and no exposure limits established. Oral exposure is accidental or associated with poor hygienic practices, is very difficult to assess, and there are no occupational exposure limits of oral intake. Also accidental injuries caused by needles or other sharp objects that might be contaminated by chemicals occur but exposure assessment in this condition is almost impossible. Exposure is also assessed by biologic monitoring that entails measurements of the substance and/or of its metabolite(s) in accessible fluids, generally urine, blood, or expired air. Biochemical changes, e.g., enzyme inhibition, associated with exposure are also measured. The results of these measurements are compared with existing limit values in order to conclude on the safety of the working conditions. Since the limit values are derived with the application of conservative assumptions, there are no fine lines between health and disease. Therefore, in the clinical setting values below the limit can be generally regarded as safe. Values above the limits should be considered in conjunction with all other information to judge on the likelihood that the disease under investigation may have been caused by exposure to the substance.

BP-C1 in the treatment of patients with stage IV breast cancer: a randomized, double-blind, placebo-controlled multicenter study and an additional open-label treatment phase

The aims were to compare the efficacy and tolerability of a new benzene-poly-carboxylic acids complex with cis-diammineplatinum (II) dichloride (BP-C1) versus placebo and to investigate the long-term tolerability of BP-C1 in the treatment of patients with metastatic breast cancer.

Pentoxifylline and its applications in dermatology

Pentoxifylline is a methyl-xanthine derivative with many anti inflammatory effects. Pentoxifylline has been found to be effective for many dermatological as well as non-dermatological conditions. It has been used both as primary drug as well as adjuvant and is a safe and relatively cost-effective alternative drug. In this article, we review the literature and highlight various important aspects of pentoxifylline.

Development of a Nanoparticle-Embedded Chitosan Sponge for Topical and Local Administration of Chemotherapeutic Agents

The following work describes the development of a novel noninvasive transmucosal drug delivery system, the chitosan sponge matrix (CSM). It is composed of cationic chitosan (CS) nanoparticles (NPs) that encapsulate cisplatin (CDDP) embedded within a polymeric mucoadhesive CS matrix. CSM is designed to swell up when exposed to moisture, facilitating release of the NPs via diffusion across the matrix. CSM is intended to be administered topically and locally to mucosal tissues, with its initial indication being oral cancer (OC). Currently, intravenous (IV) administered CDDP is the gold standard chemotherapeutic agent used in the treatment of OC. However, its clinical use has been limited by its renal and hemotoxicity profile. We aim to locally administer CDDP via encapsulation in CS NPs and deliver them directly to the oral cavity with CSM. It is hypothesized that such a delivery device will greatly reduce any systemic toxicity and increase antitumor efficacy. This paper describes the methods for developing CSM and maintaining the integrity of CDDP NPs embedded in the CSM.
