A critical appraisal of the International Classification of Headache Disorders migraine diagnostic criteria based on a retrospective multicenter cross-sectional headache registry study in youth.

We used Cluster Analysis of Migraine-associated Symptoms (CAMS) to critically evaluate current International Classification of Headache Disorders-Third Edition (ICHD-3) migraine-associated symptoms criteria. Diagnostic criteria play a central role in guiding clinical trial inclusion, and therefore available treatments. Migraine and tension-type headaches (TTH) are differentiated in ICHD-3 by many headache characteristics, including associated symptoms. A diagnosis of probable migraine indicates some but not all features of migraine are met. Photophobia and phonophobia, or nausea and/or vomiting, are required to meet a diagnosis of migraine; however, CAMS-a model that describes associated symptoms across youth with headache-indicates that a broader range of symptoms contain information about migraine burden. In this multisite retrospective cross-sectional study, we evaluated ICHD-3 migraine criteria. Youth aged 6-17 years with migraine (including probable migraine) or TTH were included in the analysis. We used CAMS to evaluate the migraine-associated symptom criterion. With CAMS as a guide, we evaluated how changes to the migraine-associated symptom criterion altered who met the diagnosis of migraine. Of the 9017 participants included in this study, 66.7% were female and had a median (interquartile range) age of 13 (10-15) years. Most participants had migraine or probable migraine (99.0%), and the remainder had TTH (1.0%). A sizable percentage (10.1%) of youth under the umbrella diagnosis of migraine were diagnosed with probable migraine because they did not meet migraine-associated symptom criterion D; however, many in this group reported several non-ICHD migraine-associated symptoms. We explored alterations to criterion D based on CAMS. Allowing for photophobia or phonophobia re-categorized 55.6% of youth as having migraine, though some only had one symptom. Including lightheadedness or lightheadedness and spinning re-categorized 19.7% and 25.8% of youth with migraine, respectively, but all of those who were re-categorized had at least two migraine-associated symptoms. The ICHD-3 captures the most prevalent migraine-associated symptoms; however, many youths with probable migraine who do not meet full criteria due to insufficient associated symptoms nonetheless experience multiple non-ICHD migraine-associated symptoms. Changes to criterion D should be considered for the ICHD-4.

The Effect of Perceptions of Evidence-Based Practice on Endotracheal Cuff Pressure Management in Critical Care Nurses: A Correlational Cross-Sectional Multicentre Study.

This correlational cross-sectional multicentre study aims to achieve two objectives. Firstly, to assess nurses' knowledge and practice of endotracheal cuff pressure management. Secondly, to examine the relationship between endotracheal cuff pressure management knowledge and evidence-based practice leadership and work environment. A correlational cross-sectional multicentre study design. This study was conducted among 144 intensive care nurses in Turkey. Data collection included descriptive characteristics and cuff pressure management of nurses, the Evidence-Based Practice Leadership Scale and Evidence-Based Practice Work Environment Scale. Descriptive statistics, chi-square test, Pearson correlation and receiver operating characteristics analysis were conducted. A STROBE checklist was the reporting guide for this study. The success status of nurses in terms of knowledge related to cuff pressure was found significantly different according to the type of intensive care unit working in and the status of receiving training on evidence-based practice. A positive, strong relationship was found between nurses' mean scores on the Evidence-Based Practice Leadership Scale and the Work Environment Scale. There was a very weak positive correlation between the mean scores of the Evidence-Based Practice Leadership Scale and the cuff pressure management. Adherence by nurses to current evidence-based practice for cuff pressure monitoring is essential for safe patient care and improved quality of care. It is recommended to provide both a supportive working environment and training programmes for intensive care nurses to perform cuff pressure management in line with evidence-based practice. Providing educational programs, an appropriate clinical environment, support from health managers and access to appropriate tools are important considerations in increasing the knowledge and skills of intensive care nurses to effectively monitor and manage cuff pressure. Our study complies with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Checklist: cross-sectional studies. No patient or public contribution.

Cluster Analysis of Migraine-associated Symptoms (CAMS) in youth: A retrospective cross-sectional multicenter study.

To conduct a retrospective cross-sectional multicenter study to validate the relationships between migraine-associated symptoms. Symptoms associated with headache-photophobia and phonophobia, nausea, and/or vomiting-are required criteria for migraine diagnosis based on the International Classification of Headache Disorders-Third Edition (ICHD-3). However, individuals with migraine report high rates of other symptoms (e.g., lightheadedness, difficulty thinking). We recently completed a single-center study assessing the relationships between an expanded set of migraine-associated symptoms. A pre-registered cross-sectional multicenter retrospective analysis was conducted on standardized questionnaire data of youth ages 6-17 years from two headache registries at pediatric tertiary care centers. Cluster Analysis of Migraine-associated Symptoms (CAMS) was implemented to assess associations between 11 migraine-associated symptoms. We explored differences between the two centers, and how CAMS was associated with demographics, including sex and age, and headache burden. There were 10,721 participants who were 66.5% female and had a median (interquartile range) age of 13 (10-15) years. The first three CAMS dimensions accounted for 46.5% of the variance and were consistent across sites. The first dimension indicated those reporting any migraine-associated symptoms were likely to report multiple. The second dimension separated symptoms into those included in ICHD-3 migraine diagnostic criteria and non-ICHD symptoms (e.g., lightheadedness, difficulty thinking). The third dimension separated sensory hypersensitivity and vestibular symptoms. An abundance of migraine-associated symptoms correlated with greater headache severity (Spearman's ρ = 0.18, 95% confidence interval [CI] 0.17-0.20; small effect size) and disability (ρ = 0.26, 95% CI 0.25-0.28; small effect size). We also observed differences in associated symptoms across age and sex. Associations between an expanded set of migraine-associated symptoms are informative for headache burden and reveal intriguing changes across child development and sex. We were able to replicate findings across two centers, indicating that these symptom clusters are inherent to migraine.

Prevalence of frequent premature ventricular contractions and left-ventricular systolic dysfunction in patients receiving Holter monitoring.

Premature ventricular contractions (PVCs) are frequently observed with left ventricular (LV) systolic dysfunction, although the prevalence of these associated conditions in the general population remains unknown. We sought to understand the prevalence of frequent PVCs (defined PVCs > 5%) and high burden PVCs (defined PVCs > 10%) and LV systolic dysfunction in patients receiving ambulatory Holter monitors (HM). A prospective multicenter (eight US medical centers) cross-sectional study collected demographic and PVC burden data from consecutive patients undergoing 24-h, 48-h, and 14-day HM (July 2018-June 2020). Left ventricle ejection fraction (LVEF) data was collected if obtained within 6 months of HM. Four PVC burden groups were analyzed (<1%, 1%-5%, 5.1%-10%, and >10% burden) and stratified by normal LVEF (≥50%) or presence LVEF < 50%. The prevalence of PVC burden of 5.1%-10% and >10% was 4% and 5%, respectively in the population undergoing HM (n = 6529). Age was significantly different between PVC groups (p < .001). In those with LVEF assessment (n = 3713), the prevalence of LVEF < 50% and both LVEF < 50% and PVC > 5% was 16.4% and 4.2%, respectively. The prevalence of PVC > 5% and PVC > 10% in patients with LVEF < 50% was 26% and 16%, respectively. PVC > 5% were more prevalent in older, male, and Caucasians (p < .001). Females had a lower prevalence of PVC > 5% than males (6% vs. 11%; p < .001), but not among those with LVEF < 50% (24% vs. 26%, p = .10). PVC > 5% and PVC > 10% and LVEF < 50% are prevalent in patients undergoing HM. PVC > 5% are associated with older age. Females have a lower prevalence of PVC > 5% than males but similar combined PVC > 5% and LVEF < 50%. gov identifier: NCT03228823.

Readiness to manage Ebola Virus Disease among emergency healthcare workers in Uganda: a nationwide multicenter survey

BackgroundEmerging infectious diseases like the Ebola Virus Disease (EVD) pose significant global public health threats. Uganda has experienced multiple EVD outbreaks, the latest occurring in 2022. Frontline healthcare workers (HCWs) are at increased risk, yet there is insufficient evidence of existing knowledge of EVD of these HCWs. We aimed to assess the readiness of Uganda’s emergency HCWs to manage EVD and identify their training needs to inform targeted capacity-building interventions for future outbreaks.MethodsThis multicentre nationwide cross-sectional study was conducted from July to September 2023 among HCWs providing emergency care in 14 secondary and tertiary hospitals across Uganda. Participants were consecutively recruited using the probability-proportional-to-size sampling technique, and data was collected using a self-reported questionnaire. Factors associated with EVD knowledge were identified through a mixed-effect linear model.ResultsData from 691 eligible HCWs with a median age of 32 (IQR: 28–38) was analyzed (response rate: 92%). Only one-third (34.4%, n = 238) had received EVD training in the past year. The median EVD knowledge score was 77.4% (IQR: 71.2 − 83.4%). EVD knowledge was associated with longer professional experience in years (β: 0.21, 95% CI: 0.03 to 0.39, p = 0.024) and higher level of education: diploma (β: 3.37, 95% CI: 1.49 to 5.25, p < 0.001), undergraduate degree (β: 6.45, 95% CI: 4.11 to 8.79) and postgraduate degree (β: 7.13, 95% CI: 4.01 to 10.25, p < 0.001). Being a doctor (β: 2.55, 95% CI: 0.35 to 4.74, p = 0.023), providing care in the obstetrics/gynecology department (β: −1.90, 95% CI: −3.47 to − 0.32, p = 0.018), previous EVD training (β: 2.27, 95% CI: 0.96 to 3.59, p = 0.001) and accessing EVD information through social media (β: 2.52, 95% CI: 1.17 to 3.88, p < 0.001) were also significantly associated with EVD knowledge. HCWs were mostly interested in training on management (92.9%), infection prevention and control (87.1%), and clinical presentation (84.1%), and preferred physical (51.5%) and hybrid (38.2%) training modes.ConclusionOur study shows that the readiness of HCWs in Uganda to respond to EVD outbreaks varies by individual factors and information sources. We recommend targeted training and suggest future research on educational innovations and social media’s potential to fill knowledge gaps.

Educational needs and its associated factors among patients with ankylosing spondylitis in China: a multicenter cross-sectional study.

Patient education is an important part of ankylosing spondylitis (AS) management. Effective patient education should be targeted at specific priorities and needs of the patients. However, the educational needs of patients with AS in China have not been systematically explored. The purpose of this study was to assess the level of educational needs and analyze associated factors in patients with AS in China. This multicenter cross-sectional study was conducted at five hospitals in China. The Chinese version of the Educational Needs Assessment Tool (ENAT) was used to measure educational needs. Disease activity and physical function were assessed using the Bath Ankylosing Spondylitis Functional Index (BASFI) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Multiple linear regression analysis was used to identify the predictors of educational needs. This study included 163 patients with AS. The mean ENAT score was 86.25 (31.64). Patients wanted to know more about the arthritis process, self-help measures, and treatments. Multiple linear regression analysis indicated that younger age, being female, higher disease activity, and no family history of AS (p < 0.05) were positive predictors of educational needs. Patients with AS in China have considerable educational needs, particularly in the domains of arthritis, self-help, and treatment. Female patients and patients with younger age, higher disease activity, and no family history may have higher educational needs. These factors should be considered when conducting need-based patient education programs. Healthcare professionals should integrate need-based patient education into rheumatology care in the future.

Behavioral and Psychosocial Dynamics in Diabetes Management: A Path Analysis to Examine the Influence of Acculturation in Arab Immigrant Communities.

Type 2 diabetes mellitus (T2DM) prevalence is rising globally. Arab immigrants with T2DM, one of the least studied ethnic minorities, have a higher diabetes prevalence and more prominent management-related challenges compared with mainstream host societies. Acculturation's impact on self-care activities and diabetes distress (DD) is understudied globally. To examine how acculturation affects self-care practices and DD in first-generation Arab immigrants with T2DM and how health literacy, illness perceptions, and self-efficacy mediate these associations. This multicenter cross-sectional study was conducted in Victoria, Australia. Eligible patients were invited while waiting for their appointments. The questionnaire included validated tools to assess DD, self-care activities, health literacy, self-efficacy, and acculturation. We tested mediation hypothesis using path analysis, with a maximum likelihood estimation to calculate total, direct, and indirect effects and bias-corrected accelerated 95% CI. Overall, 382 Arab immigrants with T2DM participated, with an average age of 57.9 years (SD = 8.0). Half were males, most had low education, and were married. Participants lived in Australia for a mean of 19.1 years (SD = 8.3) and had diabetes for 7.1 years (SD =4.7). Higher acculturation was directly associated with decreased DD. Illness perceptions (p = .002) and self-efficacy (p = .001) mediated the association of acculturation with self-care activities, while health literacy did not. Additionally, self-efficacy fully mediated the relationship between acculturation and DD (p = .001). This research provided valuable insights into the complex interplay between acculturation, diabetes management, and psychosocial factors. Interventions targeting self-efficacy and illness perceptions may improve self-care activities and reduce DD among Arab immigrants with T2DM.

Death Preparation and Quality of Life amongst Family Caregivers of Terminal Cancer Patients: A Multicentre Cross-sectional Study

Objectives: Caring for ill cancer patients imposes a considerable burden on families, significantly reducing quality of life (QoL). This study examined the association between death preparation and QoL amongst family caregivers (FCs) of terminally ill patients with cancer in South Korea. Materials and Methods: A multicentre cross-sectional survey using questionnaires was conducted in nine inpatient palliative care units in South Korea. Data from 170 FCs who answered questions about preparedness for death were analysed. A stepwise multivariate logistic model was used to identify the factors associated with FCs’ QoL. The estimated QoL scores were also compared between the groups according to preparedness level. Results: Factors associated with high QoL included old age, fewer daily caregiving hours, fewer caregiving durations and practical preparedness for death. The well-prepared group had significantly higher QoL scores in the burdensome domain. This significant association remained robust in FCs with low educational or social support levels, poor resilience and dysfunctional families. Conclusion: Practically, well-prepared FCs experienced a high QoL in hospice care settings. FCs are likely to benefit from assessment and encouragement of their preparedness for death.

The Black and African American Connections to Parkinson’s Disease (BLAAC PD) study protocol

Determining the genetic contributions to Parkinson’s disease (PD) across diverse ancestries is a high priority as this work can guide therapeutic development in a global setting. The genetics of PD spans the etiological risk spectrum, from rare, highly deleterious variants linked to monogenic forms with Mendelian patterns of inheritance, to common variation involved in sporadic disease. A major limitation in PD genomics research is lack of racial and ethnic diversity. Enrollment disparities have detrimental consequences on the generalizability of results and exacerbate existing inequities in care. The Black and African American Connections to Parkinson’s Disease (BLAAC PD) study is part of the Global Parkinson’s Genetics Program, supported by the Aligning Science Across Parkinson’s initiative. The goal of the study is to investigate the genetic architecture underlying PD risk and progression in the Black and/or African American populations. This cross-sectional multicenter study in the United States has a recruitment target of up to 2,000 individuals with PD and up to 2,000 controls, all of Black and/or African American ancestry. The study design incorporates several strategies to reduce barriers to research participation. The multifaceted recruitment strategy aims to involve individuals with and without PD in various settings, emphasizing community outreach and engagement. The BLAAC PD study is an important first step toward informing understanding of the genetics of PD in a more diverse population.

Character strength patterns, social support and psychological distress in adolescents and young adults with cancer: A multicenter cross-sectional study

ObjectiveAdolescents and young adults with cancer (AYAC) experience severe psychological distress worldwide. Social support was associated with reduced distress among cancer patients, but the role of character strength patterns in this association is unexplored. This study explored whether character strength patterns influence the association between social support and psychological distress in AYAC. MethodsA multicenter cross-sectional study was conducted at four hospitals in Changsha, China. Participants completed questionnaires assessing sociodemographic, distress, social support, and character strengths. Latent profile analysis determined character strength patterns, and multiple linear regression models examined the association. Interaction terms tested moderation effects, and adjusted models examined confounding, all stratified by gender. ResultsAmong 728 participants, three character strength patterns emerged: low (LCS), moderate (MCS), and high (HCS). Across all patterns, higher social support was significantly associated with lower distress in AYAC (female: β ​= ​−0.124, 95% CI ​= ​−0.051 to −0.015; male: β ​= ​−0.180, 95% CI ​= ​−0.080 to −0.030; P ​< ​0.001). AYAC with MCS and HCS experienced significantly less distress than those with LCS, across both genders. However, the association between character strength patterns and lower distress was stronger in males (MCS: β ​= ​−0.384, 95% CI ​= ​−1.898 to −1.033; HCS: β ​= ​−0.777, 95% CI ​= ​−3.420 to −2.495; P ​< ​0.001) compared to females (MCS: β ​= ​−0.284, 95% CI ​= ​−1.215 to −0.700; HCS: β ​= ​−0.593, 95% CI ​= ​−2.776 to −2.102; P ​< ​0.001). ConclusionsCharacter strength patterns didn't moderate or confound the association between social support and psychological distress, but had stronger protective effects against psychological distress than social support. Higher character strength patterns showed a stronger association with lower psychological distress, especially for males.

Knowledge, practices,and barriers to access of emergency contraceptive pills in married women and men:a multicenter clinic-based cross-sectional study from Karachi, Pakistan.

Emergency contraceptive pills (ECPs) are significantly underutilized in many parts of the world, especially in South-Asia. Within Pakistan, despite the population surge, the utilization of ECPs remains alarmingly low. The purpose of this study was to investigate the knowledge and practices regarding ECPs amongst married women and men in Karachi, Pakistan and the possible barriers hindering access to and use of these contraceptives. A multi-centric cross-sectional study was conducted in Karachi, Pakistan. Interviews were conducted with participants using validated questionnaire involving different sections on demographics, knowledge, practices, and barriers to ECP use. Categorical variables were summarized as frequencies and percentages while continuous variables were characterized using mean and standard deviation. A chi-square test of variance was used for association between knowledge scores and different categorical values. A p-value of < 0.05 at 95% CI was statistically significant. Over half of the respondents (52.5%) were not using any method of contraception. 11.1% of respondents had used ECP at some point in their life. 337 (85.8%) participants had low knowledge, 55 (14%) had moderate while only 1 (0.25%) had high knowledge regarding ECPs. There was no significant association of knowledge scores with gender, age, employment status or parity. However, participants who had received counseling for family planning in the past or had previously used ECPs had significantly higher knowledge regarding ECPs. A majority 58% (221) of the participants expressed concerns about the potential side effects and 128 (33.9%) of them believed that ECPs were in contradiction to their religious and moral values. Our study in Karachi, Pakistan, highlights critical challenges in ECP awareness, utilization, and family planning. Although the results show improved ECP usage than studies previously done in Pakistan, there is a further need to increase the reach of ECPs through a variety of methods. Persistent myths and misconceptions and a severe lack of awareness further hinders their use.

Characteristics of diabetes mellitus patients with nonviral chronic liver disease who developed hepatocellular carcinoma.

Type 2 diabetes mellitus (T2DM) is a well-known risk factor for hepatocellular carcinoma (HCC). However, HCC is often diagnosed at an advanced stage in patients with diabetes because of the lack of the best criteria for surveillance candidates. The aim of this study was to identify risk factors for HCC development in patients with diabetes with nonviral chronic liver disease. Three hundred thirty T2DM patients with nonviral chronic liver disease who underwent surveillance for HCC by imaging techniques between 2009 and 2020 were enrolled in this multicenter cross-sectional retrospective study. Theclinical and laboratory parameters of patients with and without HCC were compared. Age ≥65years, alcohol intake, lack of hepatic steatosis, triglyceride level <111mg/dL, Mac2 binding protein glycosylation isomer (M2BPGi) ≥0.9 cut-off index (COI), α-fetoprotein concentration ≥5ng/mL, and des-γ-carboxy prothrombin concentration ≥26mAU/mL were independently associated with HCC development. When stratified by age, only alcohol intake (odds ratio [OR] 114.19, p<0.001) was associated with HCC development in patients aged <65years, and medication for diabetes mellitus (OR 5.72, p=0.001), lack of hepatic steatosis (OR 4.47, p=0.002), lactate dehydrogenase ≥198IU/L (OR 2.751, p=0.031), M2BPGi ≥1.18 COI (OR 9.05, p<0.001), and FIB-4 index ≥2.59 (OR 3.22, p=0.017) were associated with HCC development in patients aged ≥65years. In addition to age and advanced liver fibrosis, alcohol intake in younger T2DM patients and medication for DM and lack of hepatic steatosis in older T2DM patients should be considered for HCC surveillance by imaging.

Determinants of medication non-adherence among patients with chronic diseases at community pharmacy settings in South Gondar Zone, Northwest Ethiopia: a multicenter cross-sectional study.

Medication non-adherence is a significant public health concern in managing patients with chronic diseases, and community pharmacists are on the frontline in the management of chronic medications. Chronic diseases require lifelong pharmacotherapy and understanding the determinants of medication adherence has paramount importance to develop strategies that improve medication adherence and treatment outcomes. Thus, this study aimed to assess the magnitude of medication non-adherence and its contributing factors among patients with chronic diseases attending community pharmacies in South Gondar Zone, Northwest Ethiopia. A multicenter cross-sectional study was conducted at community pharmacies in South Gondar Zone from September 01 to October 30, 2023. Medication adherence was assessed using a structured questionnaire using the Adherence in Chronic Diseases Scale (ACDS). Statistical Package for Social Sciences (SPSS) version 25 was used for analysis. Association between the outcome variable and independent variables was performed using binary logistic regression and a p-value of <0.05 was considered statistically significant. Among three hundred and eighty six (386) study participants recruited in this study, more than half of them 222 (57.51%, 95%CI: 52.4% - 62.5%) were low adherent to their medications. Concerning determinants of medication non-adherence; the presence of side effects (AOR =2.1, 95%CI=1.33-3.29), unable to get ever counseling from community pharmacists (AOR=2.3, 95%CI= 1.46-3.58), and poor about their medications (AOR=3.1, 95% CI= 1.96-4.82) were significantly associated with patients' non-adherence to medications. The medication adherence level in this study was suboptimal, with a significant proportion of the patients being non-adherent to their medications. The presence of side effects, unable to get ever counseling, and poor knowledge about their medications were statistically significant factors of poorer medication adherence. Hence, healthcare professionals, especially community pharmacists, have a crucial role in designing the schedule for health education concerning the needs of these patients in community pharmacy settings.

Objectively measured levels of moderate to vigorous intensity physical activity are associated with cognitive impairment in diabetic hemodialysis patients: a cross-sectional study.

The purpose of this study was to observe the relationship between objectively measured levels of physical activity and cognitive impairment (CI) in the presence or absence of diabetes in middle-aged and elderly hemodialysis patients. In this multicenter cross-sectional study, 339 clinically stable hemodialysis patients (210 males; mean age: 67.38 ± 8.07 years) aged ≥55 years were included from 7 dialysis units in Shanghai, China. The Chinese version of the Modified Mini-Mental State Examination (MMSE) was used to assess the CI. The duration of physical activity at different intensities, including moderate to vigorous physical activity (MVPA) as well as light physical activity (LPA), was measured using a triaxial accelerometer (ActiGraph GT3X+, Pensacola, FL, USA). Logistic regression and multiple linear regression were used for analyses. The prevalence of CI was higher in hemodialysis patients with comorbid diabetes (24.3%). In diabetic patients, MVPA (increase per 10 min/day) was negatively associated with CI after adjusting for covariates [(OR = 0.89, 95%CI = 0.79-0.99), p = 0.042]. However, no significant association between physical activity and CI was found in non-diabetic hemodialysis patients. Further analyses revealed that MVPA was positively associated with temporal orientation, attention and calculation and recall in diabetic hemodialysis patients. Physical activity was associated with CI in diabetic hemodialysis patients rather than the non-diabetes group. This study is important for early differential diagnosis of CI and improvement of cognitive status in hemodialysis patients.

Knowledge, attitudes, and practices on the use of local anaesthesia in the Emergency Department

Background: Local anaesthesia (LA) is frequently used in the Emergency Department (ED). Local anaesthetic systemic toxicity (LAST) is a potentially fatal complication associated with its use. It is assumed that all doctors administering LA are trained in all aspects of its use including the management of LAST.Methods: A prospective, multicentre cross-sectional study was conducted at three academic EDs in Gauteng. Doctors working in the ED completed an online questionnaire designed to assess knowledge, attitudes and practices regarding the use of LA as well as the recognition and management of LAST.Results: A total of 94 completed questionnaires were analysed. Of these, 44% of participants had graduated from medical school less than 5 years ago, and 72% had less than 5 years of experience working in the ED. The overall mean knowledge score percentage for the safe use of LA was 48.2%. The overall mean knowledge score percentage for recognition and management of LAST was 56.7%. A total of 78% of participants knew that intravenous intralipid emulsion (ILE) therapy is needed in managing LAST; however, only 25% of participants knew where to access ILE and only 33% knew how to use it.Conclusion: The overall level of knowledge on LA and the management of LAST among doctors working in the ED is low. There is also an apparent lack of awareness of the potential for toxicity despite frequent use of LA. Although the occurrence of LAST is rare, our findings highlight an obligation for continuous education on local anaesthesia and the management of LAST.Contribution: The result of this research indicates a gap in training regarding the potential for toxicity of local anaesthesia, recognition of systemic toxicity, and the management thereof. These findings suggest the possibility of misdiagnosis and under reporting of LAST.

Burden of congenital and hereditary anomalies and their epidemiological attributes in the pediatric and adult population of Peshawar valley, Pakistan

Objectives: To elucidate the burden and clinico-epidemiological attributes of congenital and hereditary anomalies (CA) in the extended Peshawar Valley of Pakistan. Method: This is a multicenter cross sectional study carried out in Buner, Charsadda, Mardan, Nowshera, Peshawar and Swabi districts, during 2017-2021. The pediatric and adult patients with CA were recruited from hospitals, public places and through door-to-door surveys. The anomalies were classified with the help of specialized clinicians. Descriptive statistics was employed. Results: In this study, 1065 independent subjects with certain types of CA from independent households were included. The index males were 71%; the majority of subjects originated from rural areas (72%), and spoke Pashto (96%). The CA were categorized into 10 major and at least 104 minor categories. There was highest representation of neurological disorders, n=375 (proportion.: 0.352; 95% CI: 0.323-0.381), followed by limb defects (n=281; prop.: 0.264), sensorineural defects (n=128; prop.: 0.120), musculoskeletal defects (n=84; prop.: 0.079), visual impairments (n=67; prop.: 0.063), hemoglobinopathies (n=40; prop.: 0.038), ectodermal disorders (n=34; prop.: 0.032), cardiovascular anomalies (n=19; prop.: 0.018), and orofacial anomalies (n=19; prop). Among the neurological disorder, intellectual disabilities and cerebral palsy were highly prevalent. The majority of the cases had a sporadic presentation (68%), and isolated occurrence (72%), whereas parental consanguinity was witnessed in 58% of cases. Conclusion: A wide range of CA were witnessed in this cohort with a preponderance of neurological disorders. The majority of the anomalies are of severe nature rendering a high morbidity burden in the population and requiring early detection, intervention and management. doi: https://doi.org/10.12669/pjms.40.10.9234 How to cite this: Naqvi SF, Ameena U, Qazi W, Ahmad S, Iqbal A, Malik S.

Sexual and reproductive health literacy and its associated factors among adolescents in Harar town public high schools, Harari, Ethiopia, 2023: a multicenter cross-sectional study.

In sub-Saharan African countries, including Ethiopia, the utilization of sexual and reproductive health information during adolescence is considered to be low. The aim of this study was to assess the level of sexual and reproductive health literacy among adolescents in Ethiopia as well as the factors associated with sexual and reproductive health literacy in this population. An institutional-based cross-sectional study design was employed. Systematic sampling methods were used to select 909 study participants. A validated scale was used, consisting of 31 questions with a 5-point Likert scale. A total score was computed, ranging from 31 (minimum score) to 155 (maximum score), which was finally categorized into limited and adequate sexual and reproductive health literacy. A multivariate linear regression model was fitted to determine the factors influencing adolescents' sexual and reproductive health literacy. The percentage of adolescents with slightly adequate and excellent sexual and reproductive health literacy was 38.9% and 6.3%, respectively. On the other hand, 677 (74.5%) participants overall had limited sexual and reproductive literacy. Healthcare workers and reading books were the preferred sources of sexual and reproductive health information that were associated with higher sexual and reproductive health literacy by 6.42 (95% CI 1.62-11.22) and 6.57 (95% CI 1.62-11.22), respectively. Adolescents' ability to pay for their healthcare was associated with better sexual and reproductive health literacy by 13.76 times (95% CI 8.21-19.32). More than three-quarters of the adolescents had limited sexual and reproductive health literacy. Sources of sexual and reproductive health information, including healthcare workers, books, and the Internet, were significantly associated with adolescents' sexual and reproductive health literacy. Hence, primary stakeholders need to incorporate sexual and reproductive health into the curriculum at high schools.
