RESUMO
Background Suicide is a significant cause of death in the world, and Pakistan, a low- and middle-income country, is no exception. Despite the increasing number of suicides, Pakistan does not have a validated suicide risk screening tool to identify suicide risk in the national language, Urdu, accurately. This study aims to translate and validate the Ask Suicide-Screening Questions (ASQ) tool into Urdu for suicide risk screening in Pakistan. Methodology We conducted this study at the Services Institute of Medical Sciences (SIMS), a large teaching hospital in Lahore, Pakistan, after receiving the approval of the SIMS Institutional Review Board. The study used a cross-sectional instrument validation study design. The inclusion criteria were youth and adults of both sexes aged 15-45 years, with an ability to understand, speak, read, and write in the Urdu language, who had no cognitive or intellectual limitation to consenting, and who were medically stable to participate. Exclusion criteria included any medical, physical, or cognitive unstable condition to consent or participate. We enrolled 300 participants in our convenience sample from the emergency department (ED), inpatient, and outpatient settings. The ASQ and the ASQ Brief Suicide Safety Assessment (BSSA) were translated and back-translated by Urdu language experts and modified to accommodate cultural and linguistic nuances. The clinician-administered BSSA Urdu version was used as a standard criterion to validate the ASQ by comparing the ASQ-Urdu responses vs. BSSA-Urdu responses. RStudio (version 2023.09.1+494) was used for statistical analyses Results The sample had an enrollment rate of 99.7% (300/301). The sample was 52% female (158/300); the mean age was 27.1 years (SD = 9.4), the overall screen-positive rate was 41.7% (125/300), and 9.3% (28/300) of the participants endorsed a past suicide attempt. In our sample, 35.9% (33/92) of outpatients, 32.2% (19/59) of inpatients, and 49.0% (73/149) of ED patients screened positive on the Urdu ASQ. The screen-positive rate was 16.9% (10/59) for participants aged 17 years and younger, 40.7% (35/86) for participants aged 18 to 25 years, and 51.6% (80/155) for participants aged 26 years and older. Compared to the criterion standard clinician-administered assessment, the Urdu ASQ had a sensitivity of 94.2% (95% confidence interval (CI) = 85.8%-98.4%), a specificity of 73.9% (95% CI = 67.7%-79.5%), a negative predictive value of 97.7% (95% CI = 94.2%-99.1%), and a positive predictive value of 52.0% (95% CI = 46.4%-57.6%). Conclusions The Urdu ASQ has strong psychometric properties, allowing healthcare professionals in Pakistan and worldwide with Urdu-speaking diaspora to identify individuals at risk for suicide efficiently. Utilizing cultural contexts in adapted screening tools improves the accuracy of suicide detection by ensuring that the tools are relevant, sensitive, and respectful to the cultural context of the individuals being assessed. High screen-positive rates in our pilot study underscore the need for early detection and intervention of suicide as a major global public health problem.
RESUMO
Background: Prior research has assessed a range of surgical treatments for pediatric urolithiasis, emphasizing the necessity of tailor-made therapeutic approaches. These studies also show the adaptability of percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), and shock wave lithotripsy (SWL) in managing diverse stone dimensions. The goal of this research was to examine the effectiveness of these varying surgical methods in treating pediatric urolithiasis. Methods: Seven digital databases were explored to gather pertinent studies, following the guidelines established by the PRISMA protocol. The retrieved studies were subsequently scrutinized to draw comparisons between the stone-free rate (SFR) and the rate of complications associated with PCNL, RIRS, and SWL. Results: The SFR evaluation revealed no notable disparity between PCNL and RIRS [odds ratio (OR) 1.43, 95% confidence interval (CI): 0.67-3.05, P=0.36]. However, it was observed that both PCNL and RIRS outperformed SWL in terms of effectiveness (OR 2.51, 95% CI: 1.19-5.29, P=0.02 and OR 2.42, 95% CI: 1.41-4.14, P=0.001 respectively). Regarding the complication rates, no significant differences were observed among the three surgical methods (OR 0.67, 95% CI: 0.49-1.59, P=0.05), albeit with various forms of complications being reported. Certain studies associated PCNL with an elevated rate of complications, specifically urinary tract infections (UTIs) and severe hematuria. Conclusions: Though PCNL and RIRS demonstrated higher effectiveness than SWL in achieving SFR, there was no significant disparity in the rates of complications across all three procedures. The study underscores the significance of personalized treatment plans, taking into account aspects such as the dimension and location of the stone, along with patient-specific characteristics.
RESUMO
The thermal and optical properties of 60TeO2-20K2TeO3-10WO3-10Nb2O5 (in mol%) glasses doped with Ho2O3, Er2O3, and Tm2O3 were explored in the present work. The thermal stability, refractive index n, extinction coefficient k, absorption coefficient α, and optical band gap of the glasses were evaluated. The UV-Vis-NIR absorption spectra, the Judd-Ofelt intensity parameter, the spectroscopic quality factor, and the emission and absorption cross-sections were calculated to investigate the effects of Er3+ and Tm3+, respectively, on the band spectroscopic properties of Ho3+ ions. The results showed that the maximum emission cross-section was approximately 8×10-21 cm2, and the values of the full width at half maximum (FWHM), quality factor (σe×FWHM), and gain coefficient of Ho3+: 5I7â5I8 were also reported. The value of the FWHM×σe was 1200×10-28 cm3, which showed greater gain characteristics than earlier study results. For 2 µm mid-infrared solid-state lasers, the glasses that were examined might be a good host material.
RESUMO
Primary immune thrombocytopenia (ITP) is an acquired autoimmune disorder characterized by an isolated decrease in platelets below 100 × 109/l after the exclusion of other conditions associated with thrombocytopenia. We investigated the role of different memory T-cell subsets, including T stem cell memory (TSCM), in children diagnosed with primary ITP and its association with therapeutic duration. This case-control study included 39 pediatric patients with acute ITP admitted to the Children's Hospital at Assiut University. Using a FACSCanto flow cytometer, CD8 + and CD4 + T-lymphocytes were gated. Five different subsets were characterized in each of these cells according to CD45RO and CD45RA expression. Afterward, gating was performed based on CCR7, CD95, and CD27. Examination of the CD8 + T cells subpopulation showed that Central memory T (TCM) and CD8+ Naïve T (TN) cells were significantly lower in ITP patients than in healthy children (p < 0.0001) and (p = 0.01), respectively. In addition, CD8 + TEMRA was significantly higher in ITP children than in controls (p = 0.001). CD4 + TCM cells were significantly lower in the ITP patient group (p = 0.04). However, CD4 + TEM was significantly higher in patients than controls (p = 0.04). Our research found that ITP patients had an imbalance in the ratio of CD4+ to CD8+ T cells in the peripheral blood and that TCM cells may be involved in the pathogenetic mechanism of ITP. TCMs could help in prediction of patients with higher risk of developing ITP.

The detection of N-hexanoyl-l-homoserine lactone (C6-HSL), a crucial signal in Gram-negative bacterial communication, is essential for addressing microbiologically influenced corrosion (MIC) induced by sulfate-reducing bacteria (SRB) in oil and gas industries. Metal oxides (MOx) intercalated into conducting polymers (CPs) offer a promising sensing approach due to their effective detection of biological molecules such as C6-HSL. In this study, we synthesized and characterized two MOx/polyaniline-dodecyl benzene sulfonic acid (PANI-DBSA) nanocomposites, namely ZnO/PANI-DBSA and Fe2O3/PANI-DBSA. These nanocomposites were applied with 1% by-weight carbon paste over a carbon working electrode (WE) for qualitative and quantitative detection of C6-HSL through electrochemical analysis. The electrochemical impedance spectroscopy (EIS) confirmed the composites' capability to monitor C6-HSL produced by SRB-biofilm, with detection limits of 624 ppm for ZnO/PANI-DBSA and 441 ppm for Fe2O3/PANI-DBSA. Furthermore, calorimetric measurements validated the presence of SRB-biofilm, supporting the EIS analysis. The utilization of these MOx/CP nanocomposites offers a practical approach for detecting C6-HSL and monitoring SRB-biofilm formation, aiding in MIC management in oil and gas wells. The ZnO/PANI-DBSA-based sensor exhibited higher sensitivity towards C6-HSL compared to Fe2O3/PANI-DBSA, indicating its potential for enhanced detection capabilities in this context. Stability tests revealed ZnO/PANI-DBSA's superior stability over Fe2O3/PANI-DBSA, with both sensors retaining approximately 85-90% of their initial current after 1 month, demonstrating remarkable reproducibility and durability.
RESUMO
Background: Viral infections can cause direct and indirect damage to hematopoietic stem cells. The objectives of this study were to identify the frequency and severity of aplastic anemia in children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as well as recognize the response to treatment. Methodology: 13 children with newly diagnosed severe aplastic anemia were enrolled in this prospective clinical trial. Blood samples were obtained from all patients to detect SARS-CoV-2 antibodies, and nasopharyngeal swabs were collected for reverse-transcription Polymerase Chain Reaction to detect SARS-CoV-2 viruses. According to the laboratory results, patients were classified as having SARS-CoV-2 positive antibodies and SARS-CoV-2 negative antibodies. Both groups received combined cyclosporine (CsA) + Eltrombopag (E-PAG). The hematological response, either complete response (CR) or partial response (PR), no response (NR), and overall response (OR) rates of combined E-PAG + CsA treatment after 6 months were evaluated. Results: Four children were recognized to have aplastic anemia and SARS-CoV-2 positive antibodies. Two patients fulfilled the hematological criteria for CR and no longer required transfusion of packed red blood cells (PRBCs) or platelets, and one had PR and was still PRBC transfusion-dependent but no longer required platelet transfusion. The remaining patient showed NR, and he had died before reaching the top of the HSCT waiting list. Moreover, six patients in the SARS-CoV-2 negative antibodies group had CR, while three patients had PR. The difference in ANC, Hg, and platelet counts between both groups was not significant. Conclusion: The SARS-CoV-2 virus is added to several viral infections known to be implicated in the pathogenesis of aplastic anemia. Studies are needed to establish a definitive association and determine whether the response of bone marrow failure to standard therapy differs from that of idiopathic cases.
RESUMO
A vast range of pesticides have been routinely employed for plant protection throughout the last few decades. Pesticides can enter non-target organisms in various ways, posing health hazards. Exposure to different environmental pollutants, including pesticides, can affect the human gut flora. Metabolites generated from the gut microbiota play an essential role in the host's health by regulating metabolic homeostasis. A disruption in this equilibrium can lead to the emergence of numerous illnesses and their etiology. Pesticides have been shown in a few recent studies to harm the host's gut microbiome. As a result, there is an urgent need to investigate the impact of pesticides on gut microbiota-mediated immunity. Metabolic alterations in the host may give a better understanding of pesticide-induced harm. This review highlights the potential consequences of pesticide exposure on gut microbiota composition and function, mainly focusing on how it might alter the production of secondary metabolites with potential downstream implications for host health.
RESUMO
BACKGROUND: The rising prevalence of electronic cigarette (E-cigarette) use among adolescents is a major public health concern. This study investigates the prevalence of E-cigarette use among male adolescents in Al-Ahsa, Saudi Arabia, and explores associated factors. METHODOLOGY: A cross-sectional study was conducted from December 2022 to April 2023, involving 476 male students aged 12 to 19. Data were collected through structured questionnaires, covering sociodemographic information, E-cigarette usage patterns, reasons for use, sources of acquisition, awareness of nicotine content, and perceptions of harm. Statistical analysis was performed using SPSS 25 (IBM Corp., Armonk, NY), with significance set at p < 0.05. RESULTS: The study revealed a prevalence of 17.4% E-cigarette use among participants, with 12.6% using E-cigarettes exclusively and 4.8% concurrently with traditional tobacco cigarettes. Key findings included initiation as early as age eight, sustained and frequent use, and motivations including peer influence (61.4%), curiosity (31.3%), and flavored options (26.5%). Online platforms (34.9%) and shopping malls (28.9%) were the primary sources of E-cigarette acquisition. Most participants were aware of the nicotine content (84.3%) and believed E-cigarettes were harmful (86.7%). Importantly, 69.9% expressed intentions to quit, with 44.6% planning to do so within 30 days. Significant associations were found between E-cigarette use, education level, and having friends who smoke. CONCLUSION: This study highlights the prevalence of E-cigarette use among male adolescents in Al-Ahsa, Saudi Arabia, and identifies peer influence, curiosity, and appealing flavors as driving factors. Targeted prevention and intervention programs, along with regulatory efforts to restrict access, are urgently needed to address this growing public health issue. Increasing awareness of E-cigarette risks and providing cessation support are vital steps towards mitigating E-cigarette use among Saudi male adolescents.
RESUMO
Background: Bilateral undescended testes (BUDT) may be a marker of an underlying condition that affects sex development or maturation. Aims: To describe the extent of gonadal dysfunction in cases of BUDT who had systematic endocrine and genetic evaluation at a single tertiary pediatric center. Methods: A retrospective review was conducted of all boys with BUDT who had endocrine evaluation between 2008 and 2021 at the Royal Hospital for Children, Glasgow (RHCG). Continuous variables were analyzed using Mann-Whitney U and non-continuous variables using Fisher's exact, via Graphpad Prism v 8.0. Multivariable logistic regression was used to identify any associations between groups. A P < .05 was considered statistically significant. Results: A total of 243 bilateral orchidopexies were performed at RHCG between 2008 and 2021. Of these 130 (53%) boys were seen by the endocrine team. The median (range) age at first orchidopexy was 1 year (0.2, 18.0) with 16 (12%) requiring re-do orchidopexy. The median External Masculinization Score of the group was 10 (2, 11) with 33 (25%) having additional genital features. Of the 130 boys, 71 (55%) had extragenital anomalies. Of the 70 who were tested, a genetic abnormality was detected in 38 (54%), most commonly a chromosomal variant in 16 (40%). Of the 100 who were tested, endocrine dysfunction was identified in 38 (38%). Conclusion: Genetic findings and evidence of gonadal dysfunction are common in boys who are investigated secondary to presentation with BUDT. Endocrine and genetic evaluation should be part of routine clinical management of all cases of BUDT.
RESUMO
Due to tenoxicam (TX)'s poor aqueous solubility (0.072 mg/ml), it is poorly absorbable in the GIT, and the long-term oral administration of TX may cause severe GIT disturbances. Topical administration of TX can help in bypassing the GIT adverse effects. Therefore, in the present work, we constructed different pluronic/lecithin organogels (PLOs) for topical delivery of TX. PLO was constructed simply via direct mixing of an aqueous pluronic solution with lecithin solution. The prepared PLO formulations were characterized for their physicochemical properties including pH, drug content, visual inspection, viscosity, and spreadability. Also, the in vitro release and kinetic studies were carried out to investigate the mechanism of drug release. Moreover, the in vivo studies were carried out by investigating the anti-inflammatory and analgesic activities using albino male rats. The results showed that the modified PLOs have good physicochemical properties. The viscosity of the modified gels is a direct proportionality with both lecithin and pluronic concentrations. Also, subsequently, the drug release rate is directly proportional to gel viscosity. Moreover, the in vivo studies showed that the modified PLOs (F19) showed a significant ( < 0.05%) paw edema inhibition and pain analgesia compared with other investigated groups. Also, the results indicated that the increase in dose is accompanied by higher activity and a longer duration of action which extended to 12 h. Hence, the modified PLOs are promising safe candidates or vehicles for effective TX loading with sustained delivery behavior.

RESUMO
Background Thyroid dysfunction represents the most commonly observed endocrine illness within the population of Saudi Arabia. Thyroid cancer has been recognized as the second most commonly occurring malignant neoplasm among women in Saudi Arabia. Furthermore, there is evidence suggesting that COVID-19 and, to a certain degree, immunization may have an impact on thyroid function. The aim of this study was to evaluate the level of public knowledge, awareness, and attitudes pertaining to the manifestations and risk factors of thyroid disease. Additionally, the study sought to examine the potential role of COVID-19 as a risk factor and explore preventive measures in the context of Riyadh, Saudi Arabia. Methods A cross-sectional online survey was conducted targeting the Saudi population living in Riyadh aged 18 years and older. A self-administered questionnaire constructed on Google Forms was distributed to the general population using an online platform. The questionnaire consisted of five sections: demographic data, risk factors for thyroid disorders, clinical manifestations, prevention, and history of thyroid disease. Binary logistic regression analysis was used to identify predictors of better knowledge of thyroid diseases. Results Among the 693 participants enrolled, 57.7% were female, and 31.7% were aged between 18 and 25 years. The overall mean knowledge score was 12.2 (SD = 6.57) out of 23 points. Poor knowledge of the risk factors, clinical manifestations, and prevention was observed in 50.4% of the participants. A total of 27.6% had moderate knowledge, and 22.1% had good knowledge levels. Furthermore, only 33.9% of the participants believed that COVID-19 infection was a risk factor. The results of the binary logistic regression analysis revealed that individuals within the age range of 36-45 years, females, and students had a significantly higher level of knowledge compared to other participants (p<0.05). Conclusion This study revealed that the general population of Riyadh, Saudi Arabia, lacked adequate knowledge, awareness, and attitudes regarding the risk factors, clinical symptoms, and prevention of thyroid problems. However, middle-aged individuals, females, and those who were enrolled as students showed a higher level of knowledge. Regarding the pathogenesis of COVID-19, it was observed that all participants had a limited understanding and a lack of awareness. Insufficient public awareness may result in misunderstandings, insufficient identification, and potential oversight of COVID-19-infected patients with thyroid dysfunction. Therefore, it is imperative that healthcare authorities intensify their efforts to broaden the dissemination of information throughout the population.
RESUMO
Microscopic colitis (MC) is a chronic inflammatory disease that affects the older population. Its clinical presentation includes a variety of gastrointestinal manifestations. The main symptom is chronic watery, nonbloody diarrhea. The disease has a female predominance. The diagnosis might be challenging since the symptoms are similar to other differential diagnoses, such as celiac disease, irritable bowel syndrome, Crohn's disease, bacterial overgrowth, and infectious colitis. The golden diagnostic tool for diagnosis is performing colonoscopy to obtain the colonic biopsy, which demonstrates the characteristic histological evidence needed for diagnosis. The treatment starts with an accurate diagnosis and trial of any possible offending medications. Alternatively, there are many medications, such as bismuth or budesonide, which are very effective in treating this disease. The primary objective of this detailed review is to enhance knowledge and understanding of this condition among healthcare providers to guide them with detailed information regarding epidemiology, clinical presentation, diagnosis, and appropriate management. In the assessment of individuals presenting with persistent chronic diarrhea, it is essential for healthcare providers to consider MC as a probable differential diagnosis.
RESUMO
Introduction Ageing results in the deprivation of various physiological reserves and resources resulting in the development of frailty. Frailty in turn brings various morbidities and dependence on others for the survival of an individual making him weak and vulnerable to various infective and non-infective insults leading to death. The present study assessed frailty in rural older adults of central India by using the Frailty Index in Rural Elderly - Mental Status, Activities of Daily Living, Depression, and Events (FIRE-MADE) and correlated it with sarcopenia assessed by the Asian Working Group for Sarcopenia (AWGS) and European Working Group on Sarcopenia in Older People (EWGSOP2) criteria. Materials This study was a prospective cross-sectional study, involving 250 older adults (i.e. age >60 years) with good functional status (i.e. able to perform basic activities of daily living or more), visiting the Medicine Department of Acharya Vinoba Bhave Rural Hospital (AVBRH), Sawangi, Wardha, from December 2019 to May 2020. Frailty was assessed and estimated by FIRE-MADE frailty index (FI) and then correlated it with sarcopenia assessed by AWGS and EWGSOP2 criteria. And effects of various parameters of FIRE-MADE (like mental status, functional status, depression, polypharmacy, diabetes mellitus, chronic obstructive airway disease, ischemic heart disease, stroke and cancer) and sarcopenia on frailty were studied. Results The mean age of the present study group was 68.08±4.46 years. Out of 250, 204 (91.07%) were frail and 178 (71.2%) were sarcopenic, and among the whole study population, 72 (28.8%) were severely frail, whereas 89 (35.6%) were severely sarcopenic. Frailty and sarcopenia increase with an increase in age. Females were more sarcopenic than males in all age groups. All the components of FIRE-MADE were significant contributors to frailty, but sarcopenia was the most important factor, with an odds ratio of 295.00. Conclusion In the rural regions of India, there is an elevated probability of frailty, with sarcopenia being the main reason behind it.
RESUMO
The Kingdom of Saudi Arabia's (KSA) Ministry of Health's (MOH) healthcare transformation strategy aims to improve the quality of life of Saudi citizens in line with the 'Vision 2030' strategic objectives. The MOH is reforming the way healthcare will be managed in the future and is in the process of transferring healthcare service delivery responsibilities to clusters with ratified boards, while also moving the MOH from a provision of service model to a regulatory one. Several early pathfinding clusters were initiated in the eastern central and western regions. To ensure northern and southern regions were not left behind, the early innovation, while awaiting cluster nomination status, the northern and southern business units of Health Holding Company implemented the accelerated transformation programme (ATP). The ATP's remit was to develop capabilities and stimulate local engagement and ownership in the healthcare transformation process. This paper summarises the process of healthcare transformation undertaken in the northern and southern regions of KSA to date. It reviews the success in engaging with local healthcare professional communities in a standardised way and the learning from previous clusters, and elaborates on emerging implementation issues and how we may overcome them and introduce the lessons learnt from this journey.
RESUMO
BACKGROUND: A considerable majority of people have gastroesophageal reflux disease (GERD), a common gastrointestinal ailment. Globally, the prevalence of GERD has been rising, and it is linked to several risk factors. In this study, the incidence of GERD in a sample of the population was examined, along with the associated factors that may have an impact on it. METHODOLOGY: The Gastroesophageal Reflux Disease Questionnaire (GERD-Q) was included in a self-administered survey given to 490 participants in a cross-sectional study to help determine who was more likely to have GERD. The questionnaire collected data on demographic elements, health-related traits, and past GERD diagnoses. RESULTS: The findings revealed that 32.7% of the individuals had previously received a GERD diagnosis. Of the patients, 17.1% had a GERD-Q score of 8 or above, which indicates a higher likelihood of having GERD. Participants who had previously been diagnosed with GERD had a noticeably greater incidence of GERD, and females had a higher incidence of GERD than males. The frequency of caffeine consumption was substantially correlated with the occurrence of GERD. CONCLUSION: Our study emphasizes the value of early GERD diagnosis and therapy to reduce problems and enhance the quality of life for those who are affected. According to our research, coffee use, gender, and prior GERD diagnoses are all linked to an increased risk of developing GERD. The GERD-Q is a trustworthy and proven tool for GERD diagnosis and might be used in clinical practice to recognize GERD patients and offer suitable treatment. Additional research is required to determine how additional risk variables affect the prevalence of GERD.
RESUMO
The author reports a 19-year-old woman suffering from repeated episodes of non-bloody vomiting for 18 months. All routine and special investigations were normal. She was labeled as a case of cyclic vomiting syndrome (CVS), and she developed insomnia after the initiation of amitriptyline as a prophylactic treatment. The case was reported to increase awareness regarding the importance of monitoring medication side effects among clinicians when using different classes of medications to treat CVS.
RESUMO
Background: Secondary iron overload, alloimmunization, and increased risk of infection are common complications in patients with transfusion-dependent thalassemia (TDT). Regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) play an essential role in preventing excessive immune response. This research aimed to study the interaction between Tregs and MDSCs in TDT patients and to evaluate the association of these cell types with disease severity. Methods: This case-control study included 26 patients with TDT and 23 healthy, age- and sex-matched controls. All patients were investigated for complete blood count (CBC), serum ferritin, and flow cytometric analysis of peripheral blood to detect Tregs, MDSCs, and MDSC subsets. Results: A significant increase was observed in the frequencies of Tregs and MDSCs, particularly monocytic MDSCs (MO-MDSCs), in TDT patients compared with controls. The frequencies of these cells showed a direct association with ferritin level and total leukocyte count and an inverse association with hemoglobin level. Furthermore, a positive correlation was observed between Tregs and each of the total MDSCs and MO-MDSCs. Conclusions: Levels of Tregs and MDSCs increased in TDT and may probably have a role in suppressing the active immune systems of TDT patients.
RESUMO
Objectives: To evaluate the admission neutrophil-to-lymphocyte ratio (NLR) for risk stratification for in-hospital outcomes and complications in non-ST-elevation acute coronary syndrome (non-ST-ACS) patients. Methods: We recruited consecutive patients with non-ST-ACS. The NLR was obtained and stratified as low, intermediate, and high-risk based on <3.0, 3.0-6.0, and >6.0, respectively. The new ST-T changes, arrhythmias, contrast-induced nephropathy (CIN), and mortality were recorded. Results: Median NLR was 3 [2.1-5.3] for 346 patients with 19.9% and 30.6% in high- and intermediate-risk group. New ST-T changes were observed in 3.5% (12) out of which 8, 3, and 1 patient in low, intermediate, and high-risk group (p = 0.424), respectively. Arrhythmias were observed in 5.8% (20) with 7, 5, and 8 patients in low, intermediate, and high-risk group (p = 0.067), respectively. CIN was observed in 4.9% (17) with 5, 5, and 7 in low, intermediate, and high-risk group (p = 0.064), respectively. In-hospital mortality was recorded in 1.4% (5) with 2 and 3 patients in high and low-risk group (p = 0.260), respectively. Conclusion: A significant number of non-ST-ACS patients fall in the high-risk category of NLR. Although, the association between NLR and in-hospital mortality and adverse events was not statistically significant but relatively higher rates of events were observed in high risk group.
RESUMO
BACKGROUND: The issue of surgical safety has increased significantly over the last few decades. Several studies have established that it is linked to non-technical performance, rather than clinical competencies. Non-technical skills can be blended with technical training in the surgical profession to improve surgeons' abilities and enhance patient care and procedural skills. The main goal of this study was to determine orthopedic surgeons' requirements of non-technical skills, and to identify the most pressing issues. METHODS: We conducted a self-administered online questionnaire survey in this cross-sectional study. The questionnaire was piloted, validated, pretested, and clearly stated the study's purpose. After the pilot, minor wording and questions were clarified before starting the data collection. Orthopedic surgeons from the Middle East and Northern Africa were invited. The questionnaire was based on a five-point Likert scale, the data were analyzed categorically, and variables were summarized as descriptive statistics. RESULTS: Of the 1713 orthopedic surgeons invited, 60% completed the survey (1033 out of 1713). The majority demonstrated a high likelihood of participating in such activities in the future (80.5%). More than half (53%) of them preferred non-technical skills courses to be part of major orthopedic conferences, rather than independent courses. Most (65%) chose them to be face-to-face. Although 97.2% agreed on the importance of these courses, only 27% had attended similar courses in the last three years. Patient safety, infection prevention and control, and communication skills were ranked at the top as topics to be addressed. Moreover, participants indicated they would most likely attend courses on infection prevention and control, patient safety and teamwork, and team management. CONCLUSION: The results highlight the need for non-technical skills training in the region and the general preferences regarding modality and setting. These findings support the high demand from orthopedic surgeons' perspective to develop an educational program on non-technical skills.
