Status and Factors Affecting Patient Safety Culture at Dilla University Teaching Hospital: A Mixed-Method Cross-Sectional Study

Background Patient safety culture is now at the forefront of the global health agenda and has been designated as a human right. Assessing safety culture is seen to be a prerequisite for improving safety culture in health-care organizations. However, no research has been conducted to examine the current study setup. Therefore, this study aims at assessing the status and factors influencing patient safety culture at Dilla University Teaching Hospital. Methods This cross-sectional institutional-based study was conducted from February to March 2022 at Dilla University Hospital. The study used both qualitative and quantitative methods. A total of 272 health professionals were included in the survey. The qualitative data was collected using Key Informant Interviews and In-depth Interviews and 10 health professionals were selected purposively to meet the study objective. Results The overall composite positive patient safety culture response rate in the current study hospital was 37% (95% CI: 35.3, 38.8). Out of the 12 dimensions, teamwork within hospital units was the highest (75.3%), while frequency of event reporting was the lowest (20.7%) positive percentage response. Only two of the 12 dimensions scored above 50%. Factors affecting patient safety culture majorly at organizational and individual level were poor/low attitude of health professionals, poor documentation practice, and poor cooperation by clients, lack of training and continuous education, lack of standard operating procedure, Staff shortage and high work load. Conclusion This study revealed that the overall composite positive patient safety culture response rate within the surveyed facility was alarmingly low compared to other hospitals in various countries. The results indicate that there is a need for improvement in areas such as event reporting, documentation, health-care workers’ attitude, and staff training. Hospitals must prioritize patient safety by cultivating a strong safety culture through effective leadership, adequate staffing, and education to enhance overall patient care.
Socio-Ecological Analysis of Barriers to Access and Utilization of Adolescent Sexual and Reproductive Health Services in Sub-Saharan Africa: A Qualitative Systematic Review

Background In sub-Saharan African countries (SSA), despite the efforts to enable adolescents to access sexual and reproductive health (SRH) services, there are limited systematic review studies that comprehensively synthesize barriers to accessing services using a social-ecological model. Therefore, this review was conducted to fill this gap. Methods This study protocol was registered in the PROSPERO database (CRD42022259095). We followed PRISMA guideline to conduct this review. PubMed, Google Scholar, Embase and African Journal Online databases were used. Two authors individually screened articles. Only qualitative articles published in the English in last 10 years were included in this review. Results From the total of 4890 studies, 23 qualitative studies fulfilled the eligibility criteria. Those studies were from 11 SSA countries. This review finding revealed that inadequate information about the services, the incorrect perception about services, low self-esteem, fear of being noticed by family members, and financial constraints are barriers at the intrapersonal level. Unsupportive families and lack of open communication between adolescent-parent about sexuality issues were interpersonal barriers to access. Lack of provider competency, provider attitude, an unsupportive environment, physical inaccessibility of services, and shortage of medicine, and supplies were identified as institutional-level barriers. Moreover, community-level barriers like community stigma, social, religious, and gender norms within the society were identified as the main barriers to accessing services for adolescents. Conclusion This review finding reveals that the main barriers to access SRH services for adolescents living in SSA are misperception about services, low self-esteem to access services, financial constraints, unsupportive families, community stigma and social norms, unsupportive environments in health facilities, healthcare provider behavior, poor competency, being judgmental attitude, and breaking privacy and confidentiality. This study finding calls for new approach like a multi-pronged that works with service providers, with community, with families, and with adolescent to improve SRH services utilization of adolescent.
Comparing the Efficacy of Intra-articular Platelet-Rich Plasma and Corticosteroid Injections in the Management of Frozen Shoulder: A Randomized Controlled Trial

Introduction Periarthritis of the shoulder, or frozen shoulder (FS), is a common, painful, and disabling condition with varied treatment strategies. Intra-articular (IA) corticosteroid (CS) injections are a popular treatment option, but their efficacy is often temporary. Platelet-rich plasma (PRP) has emerged as an alternative therapy for adhesive capsulitis, but the literature on its effectiveness is limited. This study aimed to compare the efficacy of IA PRP and CS injections in managing FS. Methods In this prospective, randomized study, 68 patients who met the inclusion criteria were enrolled and randomized using a computer-generated table into two groups: Group 1 (IA PRP) received 4 ml PRP, and Group 2 (IA CS) received 2 ml (80 mg) of methylprednisolone acetate mixed with 2 ml normal saline (for a total of 4 ml) as a CS injection in the IA area of the shoulder. Outcome measures included pain; shoulder range of motion (ROM); the condensed version of the disabling conditions of the arm, shoulder, and hand (QuickDASH) score; and the shoulder pain and disability index (SPADI) score. Participants were monitored via follow-up for 24 weeks, with pain and function assessed at each evaluation using the visual analog scale (VAS) score, the SPADI score, and the QuickDASH score. Results The IA PRP injections demonstrated better long-term outcomes than the IA CS injections, significantly improving pain, shoulder ROM, and daily activity performance. After 24 weeks, the mean VAS score in the PRP and methylprednisolone acetate groups was 1.00 (1.0 to 1.0) and 2.00 (2.0 to 2.0), respectively (P≤0.001). The mean QuickDASH score was 41.83 ± 6.33 in the PRP group and 48.76 ± 5.08 in the methylprednisolone acetate group (P≤0.001). The mean SPADI score was 53.32 ± 7.49 in the PRP group and 59.24 ± 5.80 in the methylprednisolone acetate group (P≤0.001), indicating a significant improvement in the PRP group's pain and disability scores after 24 weeks. The rate of complications was similar between the two groups. Conclusions Our findings suggest that IA PRP injections provide better long-term results than IA CS injections for managing FS. Platelet-rich plasma can be used as a treatment modality for better outcomes, particularly when the patient is contraindicated or refuses CS treatment. Further research is needed to evaluate the efficacy of these treatment modalities at different stages of FS and explore the potential benefits of ultrasound-guided injections.
Analysis of deaths following yeast-derived hepatitis B vaccination of infants, China, January 2013 to December 2020

In China, adverse events following immunization (AEFI) are reported by the China AEFI Surveillance System (CNAEFIS). Serious AEFI, including deaths, are mandatorily reported and are evaluated for causality by province-or prefecture-level panels of experts. Yeast-derived HepB is the most widely used HepB in China for infants. However, the information about the death of infants caused by HepB is unclear. The CNAEFIS data on deaths following HepB from 2013 to 2020 were used for analyses. Descriptive analysis of epidemiologic characteristics was used to report death cases following HepB. We used administered doses to calculate denominators to estimate the risk of death after vaccination. During 2013–2020, there were 161 deaths following the administration of 173 million doses of HepB, for an overall incidence of 0.9 deaths per million doses. One hundred fifty-seven deaths were categorized as coincidental, and four deaths were accompanied by an abnormal reaction determined to be unrelated to the cause of death. The most common causes of death were neonatal pneumonia and foreign body asphyxia. These data provide reliable evidence on the safety of HepB among infants in China and can enhance public confidence in HepB immunization. To ensure public confidence in infants’ HepB vaccination, monitoring and scientifically evaluating AEFI-related deaths of HepB is necessary.
Beneficial effects of seaweed-derived components on metabolic syndrome via gut microbiota modulation

Metabolic syndrome comprises a group of conditions that collectively increase the risk of abdominal obesity, diabetes, atherosclerosis, cardiovascular diseases, and cancer. Gut microbiota is involved in the pathogenesis of metabolic syndrome, and microbial diversity and function are strongly affected by diet. In recent years, epidemiological evidence has shown that the dietary intake of seaweed can prevent metabolic syndrome via gut microbiota modulation. In this review, we summarize the current in vivo studies that have reported the prevention and treatment of metabolic syndrome via seaweed-derived components by regulating the gut microbiota and the production of short-chain fatty acids. Among the surveyed related articles, animal studies revealed that these bioactive components mainly modulate the gut microbiota by reversing the Firmicutes/Bacteroidetes ratio, increasing the relative abundance of beneficial bacteria, such as Bacteroides, Akkermansia, Lactobacillus, or decreasing the abundance of harmful bacteria, such as Lachnospiraceae, Desulfovibrio, Lachnoclostridium. The regulated microbiota is thought to affect host health by improving gut barrier functions, reducing LPS-induced inflammation or oxidative stress, and increasing bile acid production. Furthermore, these compounds increase the production of short-chain fatty acids and influence glucose and lipid metabolism. Thus, the interaction between the gut microbiota and seaweed-derived bioactive components plays a critical regulatory role in human health, and these compounds have the potential to be used for drug development. However, further animal studies and human clinical trials are required to confirm the functional roles and mechanisms of these components in balancing the gut microbiota and managing host health.
Emerging diversity in extracellular vesicles and their roles in cancer

Extracellular vesicles have undergone a paradigm shift from being considered as ‘waste bags’ to being central mediators of cell-to-cell signaling in homeostasis and several pathologies including cancer. Their ubiquitous nature, ability to cross biological barriers, and dynamic regulation during changes in pathophysiological state of an individual not only makes them excellent biomarkers but also critical mediators of cancer progression. This review highlights the heterogeneity in extracellular vesicles by discussing emerging subtypes, such as migrasomes, mitovesicles, and exophers, as well as evolving components of extracellular vesicles such as the surface protein corona. The review provides a comprehensive overview of our current understanding of the role of extracellular vesicles during different stages of cancer including cancer initiation, metabolic reprogramming, extracellular matrix remodeling, angiogenesis, immune modulation, therapy resistance, and metastasis, and highlights gaps in our current knowledge of extracellular vesicle biology in cancer. We further provide a perspective on extracellular vesicle-based cancer therapeutics and challenges associated with bringing them to the clinic.
Validation of depression, anxiety, and stress scales (DASS-21) among Thai nursing students in an online learning environment during the COVID-19 outbreak: A multi-center study

The Depression, Anxiety and Stress Scale (DASS-21), an introductory scale used to identify common mental disorders (CMDs) among adults, was validated across cultures in Asian populations; nevertheless, its capacity for screening these disorders may be limited for some specified groups, including nursing students. This study attempted to investigate the psychometric scale’s unique features of DASS-21 for Thai nursing students in an online learning environment during the COVID-19 outbreak. A cross-sectional study using the multistage sampling technique recruited 3,705 nursing students from 18 universities located in south and northeast Thailand. The data were gathered using an online web-based survey, and then all respondents were divided into 2 groups (group 1, n = 2,000, group 2, n = 1,705). After using the statistical methods to reduce items, exploratory factor analysis (EFA) using group 1 was performed to investigate the factor structure of the DASS-21. Finally, group 2 used confirmatory factor analysis to verify the modified structure proposed by the EFA and assess the construct validity of the DASS-21. A total of 3,705 Thai nursing students were enrolled. For the factorial construct validity, a three-factor model was initially suggested containing 18 items (DASS-18) spread across 3 components: anxiety (7 items), depression (7 items) and stress (4 items). The internal consistency reliability was acceptable with Cronbach’s alpha in the range of 0.73–0.92for either the total or its subscales. For convergent validity, average variance extracted (AVE) showed that all the DASS-18 subscales achieved convergence effect with AVE in the range of 0.50–0.67. The psychometric features of the DASS-18 will support Thai psychologists and researchers to screen CMDs more easily among undergraduate nursing students in tertiary institutions who enrolled in an online learning environment during the COVID-19 outbreak.
Introduction to seafood processing - assuring quality and safety of seafood.

Demand for seafood has consistently increased during recent years with fish protein being the major animal protein consumed in many parts of the world. According to the Food and Agriculture Organization (FAO, 2012), fresh seafood represents 40.5% of the world’s seafood production, while processed products (frozen, cured, canned, etc.) represent 45.9%. To assure the quality of raw material used for processing, fish has to be treated carefully before and after harvest. Often fish and shellfish undergo some type of handling or primary processing (washing, gutting, filleting, shucking, etc.), before the main processing occurs, to assure their quality and safety, as well as to produce new, convenient and added-value products (e.g. packed fish fillets instead of unpacked, whole ungutted fish). Processing of seafood mainly inhibits and/or inactivates bacteria and enzymes which results in shelf-life extension and also assures food safety. While the main role of processing is preservation, processing not only extends shelf life but also creates a new range of products. Seafood processing uses almost all the processing methods available to the food industry. The most widely used methods to preserve fish involve the application of low temperatures (chilling, super-chilling, freezing). Improvements in packaging technology (modified atmosphere packaging, MAP) and the application of chilling maximise quality retention as well as extending shelf life. Heating inactivates bacterial pathogens and spoilage microorganisms, which contributes to the stability and safety of the products. Irradiation is a well-established, non-thermal method, while high-pressure processing of
Metformin: A Review of Potential Mechanism and Therapeutic Utility Beyond Diabetes

Abstract Metformin has been designated as one of the most crucial first-line therapeutic agents in the management of type 2 diabetes mellitus. Primarily being an antihyperglycemic agent, metformin also has a plethora of pleiotropic effects on various systems and processes. It acts majorly by activating AMPK (Adenosine Monophosphate-Activated Protein Kinase) in the cells and reducing glucose output from the liver. It also decreases advanced glycation end products and reactive oxygen species production in the endothelium apart from regulating the glucose and lipid metabolism in the cardiomyocytes, hence minimizing the cardiovascular risks. Its anticancer, antiproliferative and apoptosis-inducing effects on malignant cells might prove instrumental in the malignancy of organs like the breast, kidney, brain, ovary, lung, and endometrium. Preclinical studies have also shown some evidence of metformin’s neuroprotective role in Parkinson’s disease, Alzheimer’s disease, multiple sclerosis and Huntington’s disease. Metformin exerts its pleiotropic effects through varied pathways of intracellular signalling and exact mechanism in the majority of them remains yet to be clearly defined. This article has extensively reviewed the therapeutic benefits of metformin and the details of its mechanism for a molecule of boon in various conditions like diabetes, prediabetes, obesity, polycystic ovarian disease, metabolic derangement in HIV, various cancers and aging.
N T ] 3 0 O ct 2 01 3 AN ARITHMETIC TRANSFERENCE PROOF OF A RELATIVE SZEMERÉDI

Recently, Conlon, Fox, and the author gave a new proof of a relative Szemerédi theorem, which was the main novel ingredient in the proof of the celebrated Green-Tao theorem that the primes contain arbitrarily long arithmetic progressions. Roughly speaking, a relative Szemerédi theorem says that if S is a set of integers satisfying certain conditions, and A is a subset of S with positive relative density, then A contains long arithmetic progressions, and our recent results show that S only needs to satisfy a so-called linear forms condition. This note contains an alternative proof of the new relative Szemerédi theorem, where we directly transfer Szemerédi’s theorem, instead of going through the hypergraph removal lemma. This approach provides a somewhat more direct route to establishing the result, and it gives better quantitative bounds. The proof has three main ingredients: (1) a transference principle/dense model theorem of GreenTao and Tao-Ziegler (with simplified proofs given later by Gowers, and independently, ReingoldTrevisan-Tulsiani-Vadhan) applied with a discrepancy/cut-type norm (instead of a Gowers uniformity norm as it was applied in earlier works), (2) a counting lemma established by Conlon, Fox, and the author, and (3) Szemerédi’s theorem as a black box.
Diagnosis of Non-Tuberculous Mycobacterial Pulmonary Disease by Metagenomic Next-Generation Sequencing on Bronchoalveolar Lavage Fluid

Purpose Metagenomic next-generation sequencing (mNGS) has been extensively used in the diagnosis of infectious diseases but has rarely been applied in non-tuberculous mycobacterial pulmonary disease (NTMPD). This study analyzed the diagnostic performance of mNGS in bronchoalveolar lavage fluid (BALF) samples to identify non-tuberculous mycobacteria (NTM). Patients and Methods A total of 231 patients with suspected NTMPD were recruited from the First Affiliated Hospital, School of Medicine, Zhejiang University, from March 2021 to October 2022. A total of 118 cases were ultimately included. Of these patients, 61 cases were enrolled in the NTMPD group, 23 cases were enrolled in the suspected-NTMPD group, and 34 cases were enrolled in the non-NTMPD group. The diagnostic performance of traditional culture, acid-fast staining (AFS), and mNGS for NTMPD was assessed. Results Patients in the NTMPD group had a higher proportion of bronchiectasis (P=0.007). Among mNGS-positive samples in the NTMPD group, a significantly higher reads number of NTM was observed in AFS-positive patients [61.50 (22.00, 395.00) vs 15.50 (6.00, 36.25), P=0.008]. Meanwhile, mNGS demonstrated a sensitivity of 90.2%, which was far superior to AFS (42.0%) and culture (77.0%) (P<0.001). The specificity of mNGS in detecting NTM was 100%, which was the same as that of traditional culture. The area under the receiver operating characteristic curve of mNGS was 0.951 (95% CI 0.906–0.996), which was higher than that of culture (0.885 [95% CI 0.818–0.953]) and AFS (0.686 [95% CI 0.562–0.810]). In addition to NTM, other pulmonary pathogens were also found by mNGS. Conclusion mNGS using BALF samples is a rapid and effective diagnostic tool for NTMPD, and mNGS is recommended for patients with suspected NMTPD or NTM coinfected pneumonia.
Psychological well-being, mental distress, metabolic syndrome, and associated factors among people living in a refugee camp in Greece: a cross-sectional study

Background Forcibly displaced people face various challenges and are therefore at higher risk of being affected by mental and physiological distress. The present study aimed to determine levels of psychological well-being, PTSD symptom severity, metabolic syndrome, and associated factors among forcibly displaced people in Greece in response to WHO’s call for evidence-based public health policies and programs for forcibly displaced people. Methods We conducted a cross-sectional study among n = 150 (50% women) forcibly displaced people originating from Sub-Sahara Africa and Southwest Asia living in a Greek refugee camp. Self-report questionnaires were used to assess psychological well-being, symptoms of PTSD, depression, generalized anxiety disorder and insomnia, perceived stress, headache, and perceived fitness. Cardiovascular risk markers were assessed to determine metabolic syndrome, and cardiorespiratory fitness was measured with the Åstrand-Rhyming Test of Maximal Oxygen Uptake. Results The prevalence of mental distress and physiological disorders was overall elevated. Only 53.0% of participants rated their psychological well-being as high. Altogether, 35.3% scored above the clinical cut-off for PTSD, 33.3% for depression, 27.9% for generalized anxiety disorder, and 33.8% for insomnia. One in four (28.8%) participants met criteria for metabolic syndrome. While the prevalence of moderate or severe insomnia symptoms and metabolic syndrome differed little from the global population, the risk of being affected by mental distress was markedly increased. In multivariable analysis, higher perceived fitness was associated with higher psychological well-being (OR = 1.35, p = 0.003) and a decreased likelihood for metabolic syndrome (OR = 0.80, p = 0.031). Participants with elevated psychiatric symptoms were less likely to report high psychological well-being (OR = 0.22, p = 0.003) and had increased odds for higher PTSD severity (OR = 3.27, p = 0.034). Increased stress perception was associated with higher PTSD symptoms (OR = 1.13, p = 0.002). Conclusion There is an elevated risk for mental distress compared to the global population and an overall high mental and physiological burden among people living in a Greek refugee camp. The findings underpin the call for urgent action. Policies should aim to reduce post-migration stressors and address mental health and non-communicable diseases by various programs. Sport and exercise interventions may be a favorable add-on, given that perceived fitness is associated with both mental and physiological health benefits.
