A new method of pulse control in cardiopulmonary resuscitation; Continuous femoral pulse check

OBJECTIVES

The reliability of manual pulse checks has been questioned but is still recommended in cardiopulmonary resuscitation (CPR) guidelines. The aim is to compare the 10-s carotid pulse check (CPC) between heart massage cycles with the continuous femoral pulse check (CoFe PuC) in CPR, and to propose a better location to shorten the interruption times for pulse check.

METHODS

A prospective study was conducted on 117 Non-traumatic CPR patients between January 2020 and January 2022. A total of 702 dependent pulse measurements were executed, where carotid and femoral pulses were simultaneously assessed. Cardiac ultrasound, end-tidal CO2, saturation, respiration, and blood pressure were employed for pulse validation.

RESULTS

The decision time for determining the presence of a pulse in the last cycle of CPR was 3.03 ± 1.26 s for CoFe PuC, significantly shorter than the 10.31 ± 5.24 s for CPC. CoFe PuC predicted the absence of pulse with 74% sensitivity and 88% specificity, while CPC predicted the absence of pulse with 91% sensitivity and 61% specificity.

CONCLUSION

CoFe PuC provides much earlier and more effective information about the pulse than CPC. This shortens the interruption times in CPR. CoFe PuC should be recommended as a new and useful method in CPR guidelines.

The effect of halofuginone use on epidural fibrosis after spinal surgery: An animal experiment

AIM

Epidural fibrosis (EF) can cause persistent low back pain after spinal surgery. Type I collagen is the main component of scar tissue formed after spinal surgery, and an antifibrotic agent is necessary for preventing fibrosis. Halofuginone is an antifibrotic agent that has an effect on type I collagen. Our study aimed to investigate the effectiveness of local halofuginone application for spinal EF after lumbar laminectomy in rats.

MATERIAL AND METHODS

Forty rats were equally divided into four groups (Groups I-IV; 10 rats in each group), and lumbar laminectomy was performed under general anesthesia. After laminectomy, Group I received saline (NaCl 0.9%) locally (control), Group II received spongostan, Group III received 0.5 mL of halofuginone-impregnated spongostan, and Group IV received 0.5 mL of halofuginone. Spongostan was used to prolong the exposure period of halofuginone. All rats were sacrificed after four weeks and evaluated according to histopathological criteria. A p-value of 0.05 was considered statistically significant.

RESULTS

Fibrosis was significantly lower in Group IV than in Group I (p 0.05). There was no significant difference in fibrosis between Group II/III and Group I. It was observed that spongostan increased fibrosis.

CONCLUSION

Halofuginone helps prevent EF after spinal surgery. However, further clinical and experimental studies are needed to assess its safety in humans.

Health Disparities, Transportation Equity and Complete Streets: a Case Study of a Policy Development Process through the Lens of Critical Race Theory

Historic disinvestment in transportation infrastructure is directly related to adverse social conditions underlying health disparities in low-income communities of color. Complete Streets policies offer a strategy to address inequities and subsequent public health outcomes. This case study examines the potential for an equity-focused policy process to address systemic barriers and identify potential measures to track progress toward equity outcomes. Critical race theory provided the analytical framework to examine grant reports, task force notes, community workshop/outreach activities, digital stories, and stakeholder interviews. Analysis showed that transportation inequities are entrenched in historically rooted disparities that are perpetuated in ongoing decision-making processes. Intentional efforts to incorporate equity into discussions with community members and representatives contributed to explicit equity language being included in the final policy. The potential to achieve equity outcomes will depend upon policy implementation. Concrete strategies to engage community members and focus city decision-making practices on marginalized and disenfranchised communities are identified.

Investigation of the clonal associations in Acinetobacter Baumannii strains isolated from the respiratory samples of patients in a tertiary research hospital

Objective

The blaOXA resistance genes and ISAba1 were examined in 70 samples from lower respiratory tract of hospitalized patients.

Materials and Methods

Of the 67 isolates obtained, almost half (46.3%) of them were from endotracheal aspirate, and most were collected from the intensive care units of the reanimation (37.3%) and internal medicine (32.8%) units.

Results

Three samples from the internal medicine intensive care unit had positive cultures. Of the multidrug resistant (MDR) samples, 70 isolates (>50%) were moderately sensitive, while fewer (10%) were resistant to tigecycline. In contrast, 100% were sensitive to colistin. All strains were found to be positive for blaOXA-23-like and blaOXA-51-like genes, whereas no blaOXA-40-like and blaOXA-58-like genes were detected. The ISAba1 positivity rate was 90.0%. Pattern 5 was mainly identified among the 22 different patterns. Of note, 50% of Pattern 5 was found in the patients of the internal medicine intensive care unit, and a third was associated with ventilator-associated pneumonia. Importantly, the internal medicine unit's equipment was found to be culture positive.

Conclusion

Findings obtained from this study suggest that isolates can easily spread through the hospital via isolate cross-contamination caused by health personnel. These contaminating isolates may be able to maintain their presence within the hospital for a long time.

The Diagnostic Value of SCUBE1 in Acute Appendicitis

BACKGROUND

SCUBE1 has recently been studied as a diagnostic biomarker for acute coronary syndrome, ischemic stroke, and acute mesenteric ischemia. The aim of this study is to evaluate the value of SCUBE1 and routine parameters used in patients diagnosed with acute appendicitis.

METHODS

Of the 150 patients admitted to the emergency department whose initial diagnosis were acute appendicitis (AA), 103 patients were excluded from the study for various reasons. Forty-seven patients with a definitive diagnose of AA and 43 volunteers were enrolled in the study. SCUBE1, Alvarado scoring (ASK), C-reactive protein (CRP), and routine tests were compared between the two groups.

RESULTS

SCUBE1 was not statistically significant between the patient and the control groups (p = 0.209). SCUBE1 was significantly higher in the CRP (+) group (p = 0.048). Both the diameter of the appendix on computerized tomography (CT) and SCUBE1 levels increased proportionally (p = 0.043). CRP was significantly higher in the perforated appendicitis (PA) compared to non-perforated appendicitis (NPA) (p = 0.007). White blood cell (WBC) count was not differential for perforation (p = 0.06).

CONCLUSIONS

Although SCUBE1 was significantly higher in CRP (+) patients, it was not a diagnostic biomarker for AA. There was a positive correlation between SCUBE1 values and the diameter of appendix measured on CT.

Toxicity assessment of hydroxyapatite nanoparticles in rat liver cell model in vitro

Hydroxyapatite nanoparticles (HAP NPs) are widely used for preparations of biomedical and biotechnological fields such as drug delivery, gene therapy, and molecular imaging. However, the current toxicological knowledge about HAP NPs is relatively limited. The present study was designed to investigate the toxicity potentials of various concentrations (0–1000 µg cm−2) of HAP NPs in cultured primary rat hepatocytes. Cell viability was detected by 3-(4,5-dimethyl-thiazol-2-yl) 2,5-diphenyltetrazolium bromide (MTT) assay and lactate dehydrogenase (LDH) release, while total antioxidant capacity (TAC) and total oxidative stress (TOS) levels were determined to evaluate the oxidative injury. The DNA damage was also analyzed via scoring liver micronuclei rates and determining 8-oxo-2-deoxyguanosine (8-OH-dG) levels. The results of MTT and LDH assays showed that the higher concentrations of dispersed HAP NPs (300, 500, and 1000 µg cm−2) decreased cell viability. Also, HAP NPs increased TOS (500 and 1000 µg cm−2) levels and decreased TAC (300, 500, and 1000 µg cm−2) levels in cultured hepatocytes. On the basis of increasing doses, the NPs as depending on dose caused significant increases of the number of micronucleated hepatocytes and 8-OH-dG levels as compared to control culture. Furthermore, the highest concentration of HAP NPs (1000 µg cm−2) exhibited cytotoxic activity. Based on these results, HAP NPs have a dose-dependent toxic effect in rat hepatocytes. Further extensive research in this field is promising and reasonable.

The psychiatry recruitment crisis across Europe: Evaluation by the European Federation of psychiatric trainees

Introduction

Recruitment of medical students and junior doctors in to psychiatry is a long-standing concern in many countries, with low proportions of medical graduates choosing it as a specialty and ongoing stigma from within the medical profession. In some countries the reverse problem is the case, with too many doctors wishing to enter psychiatry, and insufficient training places available.

Objectives

To understand the current situation within Europe with regards to recruitment in to psychiatry and to identify existing recruitment initiatives.

Methods

The European Federation of Psychiatric Trainees conducts an annual survey of all member organisations. A delegate of each national association of psychiatric trainees is asked to identify if their country has a problem with recruitment and if so, whether there were too many or too few applicants for training places. Delegates from countries with recruitment initiatives were contacted to provide further details.

Results

In 2014, a total of 31 countries completed the survey, with 17 stating that too few medical practitioners choose psychiatry. In total 8 countries with recruitment problems reported that initiatives exist to encourage doctors to enter psychiatric training. Of these, 7 responded to describe the initiatives, which included national recruitment strategies, financial incentives, careers fairs, mentoring schemes and a whole host of other projects.

Conclusions

Recruitment in to psychiatry remains a serious problem in a significant proportion of European countries, but a wide range of initiatives exist which aim to combat this shortfall. It will be important over the coming years to establish which initiatives are most effective at increasing recruitment.

Psychiatry Trainees in Turkey Considers Leaving the Country

Introduction

The brain drain of mental health professionals is an important issue especially for developing countries with inadequate recruitment rates. The European Federation of Psychiatric Trainees (EFPT) investigated the extent of migration among trainees across Europe by Brain Drain research project. Results from a non-EU country, with the lowest number of mental health professionals per 100 000 population across OECD countries might provide important clues.

Objective

To identify attitudes towards and behaviors towards international migration among psychiatry trainees from Turkey.

Method

An online survey was conducted among psychiatry trainees from Turkey in 2013, as part of the EFPT Brain Drain Research Project.

Results

Of 107 trainees surveyed, 74% considered living abroad. However, the rate of having even short mobility experience was just 13%, and these were mainly educational visits. More than half of those who visited a foreign country reported to have a satisfactory experience, which might explain the positive influence of these visits on attitudes towards migration. Responders perceived academic conditions as the most important aspect of training that needs to be improved, in line with the fact that inadequate training programs were important reasons for migrating.

Conclusion

Overall, psychiatry trainees in Turkey tend to remain in their country of origin, which may protect healthcare system against the detriment of workforce loss. The relatively low rate of migration may also reflect the legislative barriers (e.g. being o non-EU country) impeding migrating. Our findings also suggest that the unmet educational needs of trainees require immediate attention.

Should all psychiatrists be skilled to practice psychotherapy?

Psychiatrists have a unique place in the spectrum of mental health services, as being able to integrate psychotherapy and pharmacotherapy in clinical practice. It is through psychotherapy training that a trainee gains optimal communicative skills and competence in establishing therapeutic alliance with a patient. It helps developing empathic understanding, which is very important for a good collaboration and enable understanding, diagnostic and treatment. It improves trainees’ own insight. All are these fundamental aspects of a biopsychosocial approach of psychiatry.

In many countries psychiatry trainees have a positive attitude towards psychotherapy during their training. Moreover, patients often prefer and adhere to combined psychotherapy and medication than split-care treatments. Research in psychotherapy provides ample evidence that these treatments are effective. The UEMS considers psychotherapy education as mandatory. EFPT advocates that all trainees must gain competence in at least one recognized form of psychotherapy and have a basic knowledge for other forms. Altogether, there is a consensus among all actors of mental health services that psychotherapy training is essential and should be improved. Yet, it is still far from being a priority in psychiatric training and is subdued by biological training and research, which is easier, faster and prevailing in training institutions. Also, psychotherapy training is found less affordable by trainees.

With collaboration from other organizations, EFPT aims to improve standards of psychiatry training, including psychotherapy. We present some initiatives led by UEMS, EPA, WPA and ECNP. Today's technology allows trainees to reach various psychotherapeutic training availabilities, including online tools (Webinar, MOOCs, online guidebooks) and international courses. It is advisable that training institutions devote more time on psychotherapy training and supervision, associations provide costly training availabilities or scholarships, encourage more scientific research on psychotherapeutics and take into account the progress of research in psychology and neuroscience [1–5].

A new family with hereditary hyperferritinemia cataract syndrome

Hereditary hyperferritinemia cataract syndrome (HHCS) is a rare disorder with an autosomal dominant trait. The disease is defined with early onset cataract and hyperferritinemia without iron overload. Here, we report a new family with three affected members of this syndrome where the proband presented with high ferritin levels. Patients with unexplained high ferritin levels and/or juvenile onset cataract must be evaluated carefully for hereditary hyperferritinemia cataract syndrome.

Relationship between dyslipidemia, C-reactive protein and serological evidence of Chlamydia pneumoniae in Turkish patients with coronary artery diseases

Relationship between dyslipidemia, C-Reactive Protein (CRP) and serological evidence of Chlamydia pneumoniae was investigated in a Turkish population with coronary artery disease. This prospective, randomized, blinded study was carried out in Florence Nightingale Hospital which is affiliated to Kadir Has University, Medical Faculty. Thirty-two patients with acute coronary artery diseases (ACAD), 32 patients with chronic coronary artery diseases (CCAD) and 26 healthy controls (HC) were included in the study. We detected serum concentrations of C. pneumoniae IgG, IgA and IgM by ELISA method. We measured total cholesterol, trigliseride, LDL and HDL- cholesterol levels to determine dyslipidemia which was defined as total cholesterol >200 mg/dL, trigliserid > 150 mg/dL, LDL >130 mg/dL, HDL <45 mg/dL. CRP levels were also measured. Seropositivity to C. pneumoniae IgG was 84.3%, 100% and 65.3%; seropositivity to IgA was 9.3%, 6.2%, and 3.8%; and seropositivity to IgM was 12.5%, 15.3%, and 15.4% in patients with ACAD, CCAD and HC, respectively. Dyslipidemia was found as 93.7%, 78. 1% and 0% of patients with ACAD, CCAD and HC, respectively. CRP level was high in all patients (ACAD, CCAD) but not in healthy controls. As a conclusion, we found a significant association between seropositivity to C. pneumoniae IgG and dyslipidemia and CRP levels in ACAD and CCAD patients (p<0.05). C. pneumoniae IgG antibodies should be evaluated together with serum lipids and CRP levels in patients with ACAD and CCAD in Turkish population. This may help clinicians in treatment of C. pneumoniae infection and decrease the risk of coronary artery diseases.

Comparison of five antimicrobial regimens for the treatment of brucellar spondylitis: a prospective, randomized study

Brucellosis, a zoonosis with worldwide distribution, is a systemic infection and still an important public health problem in Turkey. The best antimicrobial combination and schedule for the treatment of brucellosis with spondylitis has not yet been clearly determined. In a prospective and randomized study, we compared the efficacy of five antimicrobial regimens for treatment of 102 patients with lumbar brucellar spondylitis. Patients were randomly assigned to receive antimicrobial combination therapy. Twenty patients received streptomycin 1 g/day intramuscularly for 15 days and tetracycline-HCl, 500 mg every 6 h orally for 45 days (ST), 21 patients received streptomycin 1 g/day i.m. for 15 days and doxycycline 100 mg every 12 h orally for 45 days (SD), 20 patients received doxycycline 100 mg every 12 h orally for 45 days and rifampicin 15 mg/kg per day in a single morning dose orally for 45 days (DR), 19 patients received ofloxacin, 200 mg every 12 h orally for 45 days and rifampicin 15 mg/kg per day in a single morning dose orally for 45 days (OR), and 22 patients received streptomycin 1 g/day i.m. for 15 days and doxycycline 100 mg every 12 h orally for 45 days plus rifampicin 15 mg/kg per day in a single morning dose orally for 45 days (SDR). Initial therapeutic failure occurred in 2 patients (10%) in the ST regimen group, 4 patients (19%) in the SD group, 3 patients (15%) in the DR group and 5 patients (26%) in the OR regimen. In addition, 2 patients (10%) in the DR group and 5 patients (26%) in the OR regimen relapsed during the follow-up period. There was no relapse in any patients in the ST, SD, and SDR groups. The response rates were 90% in the ST and 81% in the SD groups. In contrast, there was a maximum good response (100%) and no relapse in the SDR group. In conclusion, a combination of doxycycline, streptomycin, and rifampicin can be recommended as therapy for brucellar spondylitis and to reduce relapse rates.

False-positive reaction between syphilis and hepatitis C infection

There are limited data about false-positive reactions against hepatitis C virus (HCV) in syphilitic patients and false-positive reactions against syphilis in the patients with HCV infection. The aim of this study was to demonstrate the false-positivity of syphilis in patients with HCV infection, the false-positivity of anti-HCV in patients with syphilis and the validity of the serological tests in such patients. Fifty patients with positive anti-HCV, 21 patients with positive VDRL and 50 healthy subjects were studied. Syphilis serology was determined by the Venereal Disease Research Laboratory (VDRL) test and microhemagglutination for T. pallidum (MHA-TP) test. Hepatitis C serology was determined by a second generation ELISA (Ortho Diagnostics) test for HCV antibody, and anti-HCV positive patients were tested for HCV RNA by polymerase chain reaction (PCR). All assays were performed on all subjects. Not only the false-positive VDRL reaction in the patients with HCV infection but also false-positive anti-HCV tests in syphilitic patients have been observed. Four patients with syphilis had positive anti-HCV and negative HCV-RNA, whereas 10% (5 of 50) of patients with hepatitis C infection had positive VDRL and these patients were negative for MHA-TP test. The rates of false-positivity of VDRL and anti-HCV were higher than within the control group (p < 0.05). According to these data, positive anti-HCV in syphilitic patients and positive VDRL in chronic hepatitis C may be false-positive results with regard to the reaginic tests. Therefore, therapeutic measures should not be initiated without confirmation with a treponemal test or PCR. VDRL and HCV-ELISA tests may be interacted with IgM or IgG antibodies. This relationship should be investigated in further studies.

Role of staggerer gene in determining cell number in cerebellar cortex. II. Granule cell death and persistence of the external granule cell layer in young mouse chimeras

Staggerer mice (sg/sg) have a severe ataxia correlated with cerebellar Purkinje cell anomalies and granule cell death. Previous studies of adult staggerer----wild-type chimeric mice have revealed that the mutant Purkinje cell defects visible in the light microscope (small size, ectopia and reduced number) are intrinsic properties of sg/sg Purkinje cells, while the granule cell death observed in the mutant is not an intrinsic property of sg/sg granule cells. In this report we continue the study of granule cell death and examine the phenotype, observed in staggerer mutants, of the developmental persistence of the external granular layer (EGL). Four staggerer----wild-type mouse chimeras were examined at 16 or 17 days of postnatal age. Most showed intermediate amounts of granule cell pycnosis and all showed intermediate expression of EGL persistence. There was little correlation observed between the amount of granule cell pycnosis and either the genotype of the immediately underlying Purkinje cells, or the proportion of staggerer cells in the chimera as a whole (determined by the genotype ratio of other brain regions and by coat melanocytes). While the presence or absence of an EGL did not correlate with the genotype of the immediately adjacent Purkinje cells, there was good agreement between the extent of persistence of the EGL and the overall contribution of staggerer cells to the chimera. The results suggest that the intermediate numbers of granule cells observed in adult staggerer chimeras are the result of both reduced granule cell genesis and increased pruning by cell death. The findings are further discussed in terms of two possible models of staggerer gene action.
