Research progress on biodegradable polymeric platforms for targeting antibiotics to the bone. Int J Pharm 2023; 648:123584. [PMID: 37940080 DOI: 10.1016/j.ijpharm.2023.123584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 10/23/2023] [Accepted: 11/05/2023] [Indexed: 11/10/2023]
Abstract
The treatment of bone infections still involves systemic or local antibiotic therapy in high doses for prolonged periods. Current research focuses on the application of different drug delivery systems to the bone, aiming at a targeted local administration that will decrease the number of drugs used and their toxicity, compared to the systemic route. The gold standard in clinical practice is currently poly(methyl methacrylate) (PMMA) cement. The main drawback of PMMA, however, is that it is non-biodegradable, requiring a second follow-up surgery to remove the implant. Biodegradable delivery systems, on the other hand, are easily resorbable within the organism, and less invasive alternative with better patient compliance. Among biodegradable materials, natural and synthetic polymers are being studied as local drug delivery systems due to their excellent biocompatibility, sustained effect, and antibiotic release with high penetrability to infected bone and soft tissue. In this review, we focus on biodegradable polymeric platforms, such as micro- and nanoparticles, scaffolds, and hydrogels, as well as multi-delivery systems for targeting antibiotics to the bone. Additionally, we discuss the reported drug release profiles that provide important information about the systems' functionality.

Abstract
Liquid chromatography is the most applied methodology for enantioseparation in preparative and semi-preparative scale; however, flash chromatography is seldom the first choice. This work proposes a new sustainable method to achieve pure enantiomers in mg scale. Herein, the functionalization of silica for flash chromatography columns with a suitable chiral selector, for subsequent quantitative enantioseparation of chiral compounds, is described. Accordingly, the Whelk-O®1 chiral selector was bonded to flash silica and packed into a reused solid phase extraction cartridge. For the evaluation of the enantioselective performance of the flash column, the enantiomers of a chiral derivative of xanthone were quantitatively enantioseparated with an average recovery of 70% and an enantiomer ratio (e.r.) of 99% and 97% for each enantiomer. Evaluation with the anti-inflammatory drug naproxen was also performed, resulting in an average recovery of 95% and 89% and 95% e.r. for each enantiomer. The flash column showed high stability and load ability, versatility, and good reproducibility.

Abstract
New strategies for the treatment of polymicrobial bone infections are required. In this study, the co-delivery of two antimicrobials by poly(D,L-lactic acid) (PDLLA) scaffolds was investigated in a polymicrobial biofilm model. PDLLA scaffolds were prepared by solvent casting/particulate leaching methodology, incorporating minocycline and voriconazole as clinically relevant antimicrobial agents. The scaffolds presented a sponge-like appearance, suitable to support cell proliferation and drug release. Single- and dual-species biofilm models of Staphylococcus aureus and Candida albicans were developed and characterized. S. aureus presented a higher ability to form single-species biofilms, compared to C. albicans. Minocycline and voriconazole-loaded PDLLA scaffolds showed activity against S. aureus and C. albicans single- and dual-biofilms. Ultimately, the cytocompatibility/functional activity of PDLLA scaffolds observed in human MG-63 osteosarcoma cells unveil their potential as a next-generation co-delivery system for antimicrobial therapy in bone infections.

Abstract
Abstract
Background
In Portugal, cancer incidence increases annually about 3%. In 2016, cancer was the first cause of premature death, corresponding to 5 296.8 DALYs/100,000 inhabitants. The aim of this study is to estimate the number of cancers attributable to tobacco in mainland's Portugal by sex.
Methods
An observational, ecological, analytic study was performed. Data was collected by sex: tobacco consumption (current or past) in mainland Portugal resident population older than 20 years, in 1998; incidence of 12 types of cancer, by location: Esophagus (C15), Stomach (C16), Colon (C18), Rectum (C20), Liver (C22), Pancreas (C25), Larynx (C32), Lung (C34), Kidney (C64) and Bladder (C67), according to the ICD-10 classification, in 2008. The population attributable fraction (PAF), for each type of cancer, was calculated with Levin's formula. The confidence intervals (CI) were estimated by Monte Carlo simulation.
Results
The prevalence of tobacco consumption in population between 20-79 years old was 33.41% (CI 95% 32.44-34.38) and 9.88% (CI 95% 9.29-10.54) for men and women, respectively. Higher values of PAF were estimated to lung cancer (76.32% in men, 46.99% in women) followed by larynx cancer (69.55% in men, 39.13% in women).The largest number of attributed cases was estimated for lung cancer (1211 in men, 368 in women) and bladder cancer (827 in men, 114 in women). Total cancers attributable to tobacco were superior in men (3776 vs. 677).
Conclusions
In 2008, 4453 of the total common cancers in both sexes could have been avoided if there was no tobacco consumption (current and past). More cancers would have been prevented in men because they smoked more, but also because in most cancers' RR is higher in men. Actually, tobacco consumption has been increasing in women, thus, it is expected that its number of avoided cancers will approximate the one in men. Campaigns with well-defined target populations are important to increase its health level.
Key messages
Tobacco is a modifiable risk factor which can be prevented; thus it is important to promote campaigns in order to prevent early consumption. Secondary data must be used to provide evidence that will help Public Health in taking better decisions regarding interventions.

Abstract
ABSTRACT The aim of this study was to test the accuracy of a new automated computer software tool for the assessment of passive hip laxity. The hip laxity was estimated using the dedicated computer software by two blinded evaluators, one previously trained and one without specific training for distraction index measurement, in two independent sessions using 230 hip joints from 115 dogs that underwent screening for passive hip laxity using the distraction view. Previously, all of these radiographs were sent to PennHIP Analysis Center for an official distraction index record. The measurement repeatability of the two sessions was adequate for both evaluators. The reproducibility of the official distraction index measurement, mean distraction index±standard deviation 0.44±0.15, was adequate (P>0.05) for the trained evaluator, 0.44±0.15, and non-adequate (P<0.05), for the non-trained evaluator 0.47±0.17. The distraction index measurement tool proposed can be used with confidence for hip laxity evaluation by trained evaluators, as it provided good repeatability and reproducibility of official reports. The simplicity of the process described leads to a less time-consuming and more affordable procedure.

Abstract
Abstract
Introduction In order to play a wind instrument one must have a good breathing control with rhythm variation, control of inspiratory and expiratory volume as well as a good control of the airflow transmitted by the musician through the different mouthpieces. The pulmonary function of the different wind instrument players has been scarcely studied generating divergent conclusions.
Objectives To characterize and compare lung function and functional capacity of musicians of different wind instruments.
Methodology One hundred and one individuals from five philharmonic bands from Aveiro and Porto districts were studied. Smokers or ex-smokers for less than one year, respiratory pathology, history of chronic pulmonary or cardiac disease were exclusion criteria. The sample was divided into three groups: "Air reed", "Reeds" and "Metals". Pulmonary function was assessed by spirometry: forced vital capacity (FVC), forced expiratory volume in first second (FEV1), Tiffeneau index (TI), peak expiratory flow (PEF) and maximal voluntary ventilation (MVV). Functional capacity was assessed using the six-minute walk test (6-MWT). Data analysis was performed in the Statistical Package for the Social Sciences with a 95% confidence interval. Chi-square test, Mann-Whitney U test, ANOVA test and Kruskal-Wallis test were used.
Results All spirometric parameters with the exception of TI were increased in "Metals" group with significant decrease in the "Air reed" parameters of FEV1 (p = 0.045) and MVV (p = 0.004). A negative correlation between FEV1 and 6-MWT was noticed in male musicians (r=-0.291; p = 0.022).
Conclusion Musicians from the “Metals” group showed better lung function when compared to other groups. There was no positive correlation between lung function and functional capacity of the studied musicians. However, there was a weak negative correlation between FEV1 of male musicians and their functional capacity.

Abstract
BACKGROUND Neurodegenerative diseases that affect the cerebellum, especially in elderly individuals, cause impairment of motor coordination and quality of life. The presente study evaluated the electromyographic activity and thickness of the right and left masseter and temporal muscles, and the maximum molar bite force of individuals with spinocerebellar ataxia. MATERIAL AND METHODS Twenty-eight individuals were divided into two groups: those with (n=14) and without (n=14) spinocerebellar ataxia. Data on the masticatory muscles obtained from the electromyographic activity (resting, right and left laterality and protrusion), muscle thickness (maximal voluntary contraction and tensile strength) and maximum bite force (right and left) were tabulated and descriptive analysis using Student's t-test (P ≤ 0.05). RESULTS In the comparison between groups, greater electromyographic activity was demonstrated for individuals with spinocerebellar ataxia, with a statistically significant difference in protrusion and laterality for the temporal muscles (P = 0.05). There was no statistically significant difference between the groups for masticatory muscles thickness in the conditions evaluated. For maximum molar bite force, the group with spinocerebellar ataxia showed lower bite force (P ≤ 0.05). CONCLUSIONS The data obtained suggest that spinocerebellar ataxia promotes functional reduction in the stomatognathic system, mainly affecting the electromyographic activity and bite force, hindering chewing, with a resultant alteration of nutritional intake and a decrease of quality of life.

Abstract
INTRODUCTION AND OBJECTIVES Regional anaesthesia (RA) has gained popularity due to its numerous benefits and increasing safety. Yet, often patients refuse this procedure and prefer general anaesthesia (GA). This study aimed to investigate variables (demographic factors, safety perception of GA and RA, patients' fears, anxiety, and knowledge) related to patients' anaesthetic preference. MATERIAL AND METHODS Participants were patients aged 18 years or more proposed to an anaesthesia appointment for preoperative assessment. Patients completed a written questionnaire before meeting the anaesthesiologist. The questionnaire asked about their preferences, fears and perceptions about RA. RESULTS One hundred and 2patients agreed to participate. Mean age was 52.6±13.5 years, 57.8% were female and 44.5% had at least 12 years of education. Given the choice, 54.0% would prefer GA and 20.7% said they would refuse RA if proposed by the anaesthesiologist. Among patients who already experienced neuroaxial anaesthesia, 40.0% said they did not wish to repeat it. Patients who preferred GA over RA perceived GA to be safer than RA and expressed more anxiety towards being awake during surgery and more fear of feeling pain during surgery, of having back pain, and of needle puncture. Results also suggested that patients are unaware of RA's real risks and benefits. CONCLUSIONS Knowing patients' fears is essential for the anaesthesiologist address their patients' needs. Anaesthesiologists should work on improving general population perspective and knowledge about RA.

Abstract
In Portugal, the spectrum of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene variants is not known. The main objective of this work was to determine the type and frequency of CFTR variants in a sample from northern Portugal by the complete analysis of the CFTR coding sequencing performed in 512 Portuguese children. A total of 30 different CFTR sequence variants, already reported as cystic fibrosis (CF) or CFTR related disorders variants, were detected. Ninety-two children (18.0%; 95%CI: 14.7-21.6) were found to be carriers of one sequence variant and 8 (1.6%; 95%CI: 0.7-3.1) had two sequence variants. Taking into consideration only variants that may cause CF when combined with a pathogenic CF variant, the CF pathogenic variant carrier frequency was 3.3% (95%CI: 1.9-5.3). One (0.2%; 95%CI: 0.01-0.7) child presented two CF pathogenic variants. CONCLUSIONS The majority of CFTR variants detected have been associated with a less severe CF phenotype. A wide spectrum of CFTR variants was identified, confirming the highest CFTR allelic heterogeneity previously reported in Mediterranean country. Additionally, better knowledge about the CFTR sequence variation spectrum may contribute to more efficient genetic testing in the Portuguese population.

Abstract
Systolic time intervals (STI) have significant diagnostic and prognostic value to assess the global cardiac function. Presently, STIs are regarded as a promising tool for long-term follow-up of patients with chronic cardiovascular diseases. Heart sound has proven to be a valuable approach for STI estimation, in particular for the Pre-Ejection Period (PEP). However, since the optimal auscultation site varies from individual to individual, as well as with the position of the body, its application in single-channel and fixed auscultation site setups poses practical difficulties. Hence, we extend our previous work on PEP estimation to a multi-channel sound acquisition setup, where signal redundancy is exploited. A channel selection method is proposed and the best channel is selected for PEP estimation. As a preliminary study, the devised algorithms were evaluated with respect to echocardiography reference on a set of 236 heartbeats collected from 8 healthy subjects in two sound auscultation sites. The channel selection approach led to 8.4% estimation error decrease, in comparison to a single-channel approach. Current results support our assumption that a multi-channel audio-based strategy can be applied to assess STI in personal health application scenarios.

Abstract
INTRODUCTION Work organization patterns and working conditions experienced by nursing personnel in the hospital settings may be associated to increased morbidity among these health workers. AIM To estimate the prevalence and factors associated with self-reported diseases among nursing personnel at the emergency hospital in Rio Branco/State of Acre, Brazil. METHODS A cross-sectional study was conducted involving 272 participants who answered a questionnaire including sociodemographic characteristics, working conditions, lifestyles, work ability, and a fatigue perception scale. The self-reported diseases in the 12 months prior to data collection were considered the dependent variable. RESULTS A total of 85.7% of the participants reported one or more diseases in the past 12 months. Most prevalent diseases were: musculoskeletal diseases (37.1%), digestive diseases (28.7%), mental disorders (28.3%), work injuries (27.9%), and respiratory diseases (26.8%). The following significant variables remained in the final model: high work demands (OR 2.69), reported fatigue (OR 3.59), night work (OR 6.55) and being a technician or nursing assistant (OR 4.23). CONCLUSIONS Variables related to working conditions and work organization were associated with the occurrence of reported diseases among nursing professionals. Health promotion measures at work require a comprehensive approach including the working conditions and the work organization.

Abstract
BACKGROUND Endomyocardial biopsy (EMB) remains the gold standard for the diagnosis of graft rejection after heart transplantation (HT). Our purpose was to evaluate the rate of complications of this invasive procedure. METHODS This was a retrospective study of 175 patients, who were transplanted between November 2003 and October 2010 and survived more than 1 month after surgery. We evaluated the number of inconclusive EMB and described the incidence, nature, and subsequent management of several complications associated with this procedure. RESULTS Over a period of approximately 7 years, we performed 2217 EMB yielding 4972 specimens, namely, an average of 2.3 fragments per procedure. The majority of EMBs (95.3%) were performed by the femoral approach. Only 12 EMB (0.57%) were inconclusive. The overall complication rate was 0.71%. During puncture, one patient experienced a vasovagal reaction and another one, a femoral artery false aneurysm. During the biopsy, there was one case of cardiac perforation with tamponade, two cases of supraventricular tachycardia, and three atrioventricular conduction abnormalities. In 19 patients, histological analysis revealed chordal tissue, but only two patients developed mild tricuspid regurgitation. We observed five cases of coronary artery fistulae. The clinical outcomes were favorable in all cases. CONCLUSION EMB proved to be a suitable, safe method to monitor rejection after HT.

Abstract
Prompted by feedback from the 34th European Congress of Cytology (ECC), the practice of including a special symposium in the programme was continued in the 35th ECC in Lisbon (2009) by arranging a satellite symposium entitled 'Cervical Cancer Screening in the Mediterranean Countries'. Because of the importance to the future of this discipline, it was felt appropriate to summarize the highlights of this symposium here. Cervical cancer prevention strategies in the countries participating in the symposium (Portugal, Spain, Italy, Croatia, Greece and Turkey) appear to be highly variable. As yet, none of these countries can demonstrate a fully implemented national screening programme, but all are in different phases of designing and/or setting up such a programme, which is important. At present, the time-honoured concept of cervical cancer prevention by Pap smear screening is under review, because prophylactic human papillomavirus (HPV) vaccines demonstrate a potential to prevent the vast majority (albeit not all) of cases of cervical cancer in the foreseeable future. Cervical cancer screening is still needed in this emerging era of HPV vaccination, but clearly the existing screening strategies must be modified to provide a cost-effective combination of vaccination and screening. If the currently evaluated new screening strategies, such as HPV testing followed by cytology triage, become a reality, there is the likelihood that the Pap test will have only a secondary role, subordinate to HPV testing. Supporters of this scenario claim that Pap test performance will deteriorate in vaccinated populations. Reduced positive predictive value (PPV), due to lower disease prevalence, is inevitable, however, and this would also affect HPV tests. Any decline in sensitivity and specificity depends on human performance, and as such is avoidable by taking appropriate preventive measures. As clinical cytologists, we should focus attention on minimizing the risk to the Pap test of falling sensitivity because of unfamiliarity with abnormal cells, and also of reduced specificity if the fear of missing significant disease leads to overcalling of benign abnormalities.

Abstract
Leishmania are intracellular parasites that multiply as the amastigote form in the macrophages of their vertebrate hosts. Since vaccines against leishmaniases are still under development, the control of these diseases relies on prompt diagnosis and chemotherapy in infected humans as well as in dogs, which are the main reservoir of Leishmania infantum, in Mediterranean countries. To establish the macrophage type to be used as an in vitro model for antileishmanial chemotherapeutic studies, we analysed the susceptibility of human peripheral blood derived macrophages, macrophages derived from mouse bone marrow, mouse peritoneal macrophages and macrophages differentiated from cell lines U-937 and DH82 to infection by two L. infantum strains, one obtained from a human leishmanial infection and other from a canine infection. Both strains displayed comparable behaviour in their capacity of infecting the different macrophage types. Human peripheral blood macrophages and DH82 cells were less infectable by both strains. U-937, mouse peritoneal macrophages and mouse bone marrow derived macrophages are the most active cells to phagocytose the parasites. However, U-937 cell line appears to be the most useful as Leishmania infection model providing an unlimited source of homogeneous host cells with reproducibility of the results, is less time consuming, less expensive and tolerate high doses of first line drugs for human and canine visceral leishmaniasis treatment.

Prevalence, behavioural and social factors associated with Schistosoma intercalatum and geohelminth infections in São Tomé and Principe. PARASSITOLOGIA 2005; 47:227-31.

Abstract
A pilot study was conducted in schoolchildren from three main districts of São Tome to assess the relationship between the prevalence of infections caused by Schistosoma intercalatum or intestinal helminths and individual behaviour and social conditions. Coprological examination revealed an increase of schistosome infections and a persisting high endemicity for ascariasis and trichuriasis. Infection rates were 36.2% for S. intercalatum and 70.8%, 68.5% and 4.6% for Ascaris lumbricoides, Trichuris trichiura and Ancylostomidae, respectively. Out of the 47 children positive for S. intercalatum, 35 (74.5%) were co-infected with one or more geohelminths. Logistic regression analysis of data collected through questionnaire demonstrate that behaviour and/or social conditions in the house were positively associated with S. intercalatum or T. trichiura. Neither sex nor age groups were associated with infections, suggesting that low personal hygiene and sanitation practices were similar for all groups of children. These data are in accordance to those of other studies and highlight the importance of assessing multivariate factors that may contribute to the transmission of these diseases, in order to design integrated control approaches for schistosomiasis and geohelminthiasis which could have more rapid effects on reduction of infections as well as greater cost-effectiveness.

Prostaglandin E2 in the medial preoptic area produces hyperalgesia and activates pain-modulating circuitry in the rostral ventromedial medulla. Neuroscience 2004; 128:389-98.

Abstract
Prostaglandin E2 (PGE2) produced in the medial preoptic region (MPO) in response to immune signals is generally accepted to play a major role in triggering the illness response, a complex of physiological and behavioral changes induced by infection or injury. Hyperalgesia is now thought to be an important component of the illness response, yet the specific mechanisms through which the MPO acts to facilitate nociception have not been established. However, the MPO does project to the rostral ventromedial medulla (RVM), a region with a well-documented role in pain modulation, both directly and indirectly via the periaqueductal gray. To test whether PGE2 in the MPO produces thermal hyperalgesia by recruiting nociceptive modulating neurons in the RVM, we recorded the effects of focal application of PGE2 in the MPO on paw withdrawal latency and activity of identified nociceptive modulating neurons in the RVM of lightly anesthetized rats. Microinjection of a sub-pyrogenic dose of PGE2 (50 fg in 200 nl) into the MPO produced thermal hyperalgesia, as measured by a significant decrease in paw withdrawal latency. In animals displaying behavioral hyperalgesia, the PGE2 microinjection activated on-cells, RVM neurons thought to facilitate nociception, and suppressed the firing of off-cells, RVM neurons believed to have an inhibitory effect on nociception. A large body of evidence has implicated prostaglandins in the MPO in generation of the illness response, especially fever. The present study indicates that the MPO also contributes to the hyperalgesic component of the illness response, most likely by recruiting the nociceptive modulating circuitry of the RVM.
