Long-term benzodiazepine prescriptions in community psychiatry clinics.

Background: Anecdotal evidence indicates that the prevalence of long-term benzodiazepine prescription is high and not in accordance with accepted prescribing guidelines. Aim: To determine the prevalence of long-term prescriptions of benzodiazepines and associations thereof in community psychiatry clinics. Setting: Of the 27 community psychiatry clinics, 5 were randomly selected. Methods: A descriptive, retrospective, and cross-sectional record review of files of 126 adult patients was conducted, to obtain sociodemographic and clinical characteristics. Descriptive statistics were presented as proportions and percentages. Fisher's exact test was used to determine any associations between long-term benzodiazepines use and demographic and clinical variables. Regression analyses were performed to determine the significance of any such associations. Results: Approximately one out of every four patients were prescribed benzodiazepines. Most of the patients were males aged between 18 and 50 years, single and unemployed. The most common psychiatric diagnoses were bipolar disorders and psychotic disorders, and the majority had no comorbid medical illnesses or substance use. Ninety-three per cent of the patients were prescribed long-term (more than 180 days) benzodiazepines. There were no statistically significant associations between prescribing patterns and any sociodemographic and clinical characteristics (p > 0.05). Conclusion: This study found that nearly all the benzodiazepine prescriptions were long-term (over 180 days) and no statistically significant associations between this practice and any sociodemographic and clinical characteristics could be established. Contribution: There is high prevalence rate of long-term benzodiazepine prescription in community psychiatry clinics, and as such clinical monitoring systems need to be established and enforced.

Outcomes of nonsurgical endodontic treatment under general anesthesia in special health care needs: An observational study.

BACKGROUND AND AIM: The alarming rise in the number of people with special health care needs (SHCNs) necessitates a paradigm shift in how to approach their oral health needs. General anesthesia (GA) is a valuable technique for facilitating dental procedures in patients with SHCNs who may not be able to tolerate treatment without it. The aim was to assess nonsurgical endodontic treatment and outcomes in patients with SHCNs performed under GA. METHOD: Seventy-eight permanent teeth in 33 patients who received nonsurgical endodontic treatment under GA were included between 2018 and 2022 in SHCNs hospital clinics. The demographic data, types of SHCNs, pulpal and periapical diagnosis, type of treatment, and material used were analyzed. All patients were recalled for clinical and radiographic examinations. Pre-treatment and recall periapical radiographs were evaluated and scored using the Periapical Index (PAI). RESULTS: Autism and Attention deficit hyperactivity disorder were 39.4% of patients treated. Most treatments delivered were primary nonsurgical root canal treatment (95%). Warm vertical compaction of gutta-percha for obturation accounted for 88% of cases treated. Single cone obturation technique was used in 9 cases (12%) utilizing tricalcium silicate sealer. At the recall visits, 98.7% of teeth treated had survived. Twelve teeth have pre-treatment periapical lesions, and all healed except one. Female patients were found to have higher scores of PAI compared to male patients (23.7% vs 7.5%), yet insignificant. Only 10 patients with nonsurgical root canal treatment reported recurrent caries. CONCLUSION: This study demonstrates a high survival rate for nonsurgical endodontic treatment performed under GA in a cohort of patients with SHCNs. Interestingly, patients with social and communication disorders received the highest proportion of treatments under GA. These findings highlight the potential of GA-facilitated endodontics for this population. However, further research is warranted to explore additional methods for optimizing oral health outcomes in SHCNs.

Brain-Computer Interfaces for Communication in Patients with Disorders of Consciousness: A Gap Analysis and Scientific Roadmap.

BACKGROUND: We developed a gap analysis that examines the role of brain-computer interfaces (BCI) in patients with disorders of consciousness (DoC), focusing on their assessment, establishment of communication, and engagement with their environment. METHODS: The Curing Coma Campaign convened a Coma Science work group that included 16 clinicians and neuroscientists with expertise in DoC. The work group met online biweekly and performed a gap analysis of the primary question. RESULTS: We outline a roadmap for assessing BCI readiness in patients with DoC and for advancing the use of BCI devices in patients with DoC. Additionally, we discuss preliminary studies that inform development of BCI solutions for communication and assessment of readiness for use of BCIs in DoC study participants. Special emphasis is placed on the challenges posed by the complex pathophysiologies caused by heterogeneous brain injuries and their impact on neuronal signaling. The differences between one-way and two-way communication are specifically considered. Possible implanted and noninvasive BCI solutions for acute and chronic DoC in adult and pediatric populations are also addressed. CONCLUSIONS: We identify clinical and technical gaps hindering the use of BCI in patients with DoC in each of these contexts and provide a roadmap for research aimed at improving communication for adults and children with DoC, spanning the clinical spectrum from intensive care unit to chronic care.

Poly-Ether Ether-Ketone Post Conditioned with Sulfuric Acid, Rose Bengal Activated by Photodynamic Therapy and Sandblasting on Pushout Bond Strength to Radicular Dentin Luted with Methyl Methacrylate and Composite-Based Cement.

Objective: Assessment of post surface conditioners [sulfuric acid (SA), Rose Bengal (RB), and sandblasting (SB)] and different luting cements [methyl methacrylate (MMA)-based cement and composite-based cement] on pushout bond strength (PBS) of poly-ether ether-ketone (PEEK) post bonded to canal dentin. Materials and methods: Endodontic treatment was performed on 120 single-rooted human premolar teeth. The preparation of the post space was performed and 4 mm of gutta-percha was retained in the apical region of the root. One hundred and twenty PEEK posts were fabricated from a PEEK blank utilizing a Computer aided design-Computer aided manufacture (CAD-CAM) system. The PEEK posts were allocated randomly into four groups based on post surface conditioning (n = 30). Group A: SA, Group B: RB, Group C: SB, and Group D: No conditioning (NC). Each group was further divided into two subgroups based on the luting cement used for bonding (n = 15). Group A1, B1, C1, and D1 specimens were cemented using composite-based resin cement. However, Group A2, B2, C2, and D2 posts were luted with MMA-based resin cement. PBS assessment using a universal testing machine was performed. Failure modes were analyzed under a stereomicroscope. The data relating to the effects of surface treatment and luting types of cement were analyzed using one-way analysis of variance (ANOVA) and Tukey's post hoc test (p = 0.05). Results: Coronal section of Group B2: RB+Super-Bond C&B [9.61 ± 0.75 megapascals (MPa)] displayed the highest bond scores of PEEK after root dentin. Whereas it was also discovered that Group D1: NC+Panavia®V5 (2.05 ± 0.72 MPa) presented the lowest PBS scores. Intergroup comparison analysis revealed that Group A2: SA+Super-Bond C&B and Group B2: RB+Super-Bond C&B displayed no significant difference in their bond scores. Conclusions: RB and SA possess the potential to be used as a PEEK post conditioner. MMA-based cement displayed better performance than composite-based cement.

Adolescents' Internet addiction: Does it all begin with their environment?

BACKGROUND: This is one of the few studies that examines adolescent Internet addiction (IA) among Middle Eastern population. The purpose of this study is to determine whether adolescents' family and school environments play a role in their Internet Addiction. METHODS: We conduced a survey that included 479 adolescents in Qatar. The survey collected demographic data, the Internet Addiction Diagnostic Questionnaire (IADQ), the Brief Family Relationship Scale (BFRS) and questions from the WHO Health Behavior in School-aged Children (HBSC) survey that assess school environment, academic performance, teacher support, and peer support of the adolescents. Factorial analysis, multiple regression, and logistic regression were used for statistical analysis. RESULTS: Family environment and school environment were negative and significant predictors of adolescent Internet addiction. The prevalence rate was 29.64%. CONCLUSION: Results imply that interventions and digital parenting programs should not only target adolescents, but also include entities in the developmental environment of adolescents, i.e. their family and school.

Autism services in low-resource areas.

OBJECTIVES: To explore access to intervention services for children with autism spectrum disorder (ASD) in Jordan. METHODS: We used prospective cross sectional design and survey methodology to collect information from the parents of a convenient sample of children with ASD aged 2.5-17 years and who attended pediatric neurology clinics in 3 different university affiliated hospitals in 3 geographic areas in Jordan from February to December 2018. RESULTS: We interviewed parents of 274 children with ASD. One hundred ninety-six (71.5%) received rehabilitation services. The average age at first session was 3.9 years. The most common services received were behavioral therapy (182; 66.4%). The average weekly hours were highest for speech and behavioral therapy; 6.25 and 6.64 respectively. Private centers for developmental disabilities were the most commonly used followed by private centers for ASD. The most common barriers were costs (138; 58%) and transportation (88; 37.5%). Most parents (198; 72.3%) prefer to receive rehabilitation in a specialized center for autism, and most did not want to receive training to train their child themselves. CONCLUSION: Most children with ASD in Jordan have limited access to recommended autism services. The development of future interventions must consider the needs of those living in limited resource regions.

The effects of prefrontal vs. parietal cortex transcranial direct current stimulation on craving, inhibition, and measures of self-esteem.

While prefrontal cortex dysfunction has been implicated in high food cravings, other cortical regions, like the parietal cortex, are potentially also involved in regulating craving. This study explored the effects of stimulating the inferior parietal lobule (IPL) and dorsolateral prefrontal cortex (DLPFC) on food craving state and trait. Transcranial direct current stimulation (tDCS) was administered at 1.5 mA for 5 consecutive days. Participants received 20 min of IPL, DLPFC, or sham stimulation (SHAM) each day which consisted of two rounds of 10-min stimulation, divided by a 10-min mindfulness task break. In addition, we studied inhibition and subjective psychological aspects like body image and self-esteem state and trait. To decompose immediate and cumulative effects, we measured the following on days 1 and 5: inhibition through the Go/No-go task; and food craving, self-esteem, and body appreciation through a battery of questionnaires. We found that false alarm errors decreased in the participants receiving active stimulation in the DLPFC (DLPFC-group). In contrast, false alarm errors increased in participants receiving active stimulation in the IPL (IPL-group). At the same time, no change was found in the participants receiving SHAM (SHAM-group). There was a trending reduction in craving trait in all groups. Momentary craving was decreased in the DLPFC-group and increased in IPL-group, yet a statistical difference was not reached. According to time and baseline, self-esteem and body perception improved in the IPL-group. Furthermore, self-esteem trait significantly improved over time in the DLPFC-group and IPL-group. These preliminary results indicate that tDCS modulates inhibition in frontoparietal areas with opposite effects, enhancing it in DLPFC and impairing it in IPL. Moreover, craving is moderately linked to inhibition, self-esteem, and body appreciation which seem not to be affected by neuromodulation but may rely instead on broader regions as more complex constructs. Finally, the fractionated protocol can effectively influence inhibition with milder effects on other constructs.

Pharmacophore mapping of the crucial mediators of acetylcholinesterase and butyrylcholinesterase dual inhibition in Alzheimer's disease.

Optimization and re-optimization of bioactive molecules using in silico methods have found application in the design of more active ones. Herein, we applied a pharmacophore modeling approach to screen potent dual inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) aimed at Alzheimer's disease (AD) treatment. The investigation entails molecular dynamics simulation, docking, pharmacophore modeling, drug-like screening, and binding energy analysis. We prepared a pharmacophore model from approved inhibitors of AChE and BuChE to predict the crucial moieties required for optimum molecular interaction with these proteins. The obtained pharmacophore model, used for database screening via some critical criteria, showed 229 hit molecules. Further analyses showed 42 likely dual inhibitors of AChE/BuChE with drug-like and pharmacokinetics properties the same as the approved cholinesterase inhibitors. Finally, we identified 14 dual molecules with improved potentials over the existing inhibitors and simulated ZINC92385797 bound to human AChE and BuChE structure after noticing that these 14 molecules are similar. The selected compound maintained relative stability at the active sites of both proteins over 120 ns simulation. Our integrated protocols showed the pertinent recipes of anti-AD drug design through the in silico pipeline.

Brain Data in Pediatric Disorders of Consciousness: Special Considerations.

SUMMARY: The diagnosis and management of disorders of consciousness in children continue to present a clinical, research, and ethical challenge. Though the practice guidelines for diagnosis and management of disorders of consciousness in adults are supported by decades of empirical and pragmatic evidence, similar guidelines for infants and children are lacking. The maturing conscious experience and the limited behavioral repertoire to report consciousness in this age group restrict extrapolation from the adult literature. Equally challenging is the process of heightened structural and functional neuroplasticity in the developing brain, which adds a layer of complexity to the investigation of the neural correlates of consciousness in infants and children. This review discusses the clinical assessment of pediatric disorders of consciousness and delineates the diagnostic and prognostic utility of neurophysiological and neuroimaging correlates of consciousness. The potential relevance of these correlates for the developing brain based on existing theoretical models of consciousness in adults is outlined.

Conservative management of acute appendicitis in the era of COVID 19: A multicenter prospective observational study at the United Arab Emirates.

BACKGROUND & AIMS: Since its emergence in December 2019, the COVID-19 pandemic resulted in a profound impact on the health care system worldwide. We propose herein to evaluate the impact of implementing conservative management as an alternative approach to surgical appendectomy during COVID19 pandemic. MATERIALS AND METHODS: Our study is a prospective multicenter study that includes a cohort of 158 patients admitted to the surgical departments in both Tawam Hospital and SSMC hospital, Abu Dhabi, UAE, from February 2020 till July 2020. RESULTS: Our results showed a significant decrease in length of hospital stay (LOS) (2.32 ± 0.83 days) among conservatively treated group compared to the surgically treated group (2.8 ± 1.47 days). Also, short term follow-up showed that 90% of those patients did not require further operative intervention or developed complications. Out of the 110 patients that were swapped for COVID19, nine (8.18%) were confirmed to be positive. Our protocol was to avoid surgical management for COVID19 positive patients unless indicated. This resulted in (8/9) of COVID19 positive patients to be treated conservatively. CONCLUSIONS: In conclusion, our results showed that the implementation of conservative management in treating patients with acute appendicitis who were COVID19 positive maybe essential in reducing viral transmission risks as well as avoiding operative risks on COVID19 positive patients.

Tailored Modeling of Rivastigmine Derivatives as Dual Acetylcholinesterase and Butyrylcholinesterase Inhibitors for Alzheimer's Disease Treatment.

Rational modification of known drug candidates to design more potent ones using computational methods has found application in drug design, development, and discovery. Herein, we integrate computational and theoretical methodologies to unveil rivastigmine derivatives as dual inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) for Alzheimer's disease (AD) management. The investigation entails pharmacokinetics screening, density functional theory (DFT) mechanistic study, molecular docking, and molecular dynamics (MD) simulation. We designed over 20 rivastigmine substituents, subject them to some analyses, and identified RL2 with an appreciable blood-brain barrier score and no permeability glycoprotein binding. The compound shows higher acylation energy and a favored binding affinity to the cholinesterase enzymes. RL2 interacts with the AChE and BuChE active sites showing values of -41.1/-39.5 kcal mol-1 while rivastigmine binds with -32.7/-30.7 kcal mol-1 for these enzymes. The study revealed RL2 (4-fluorophenyl rivastigmine) as a potential dual inhibitor for AChE and BuChE towards Alzheimer's disorder management.

Clinical Characteristics and Histopathology of Coronavirus Disease 2019-Related Deaths in African Children.

BACKGROUND: Globally, very few childhood deaths have been attributed to coronavirus disease 2019 (COVID-19). We evaluated clinical, microbiologic and postmortem histopathologic findings in childhood deaths in whom severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified antemortem or postmortem. METHODS: Surveillance of childhood deaths was ongoing during the initial COVID-19 outbreak in South Africa from April 14, 2020, to August 31, 2020. All children hospitalized during this time had a SARS-CoV-2 test done as part of standard of care. Postmortem sampling included minimally invasive tissue sampling (MITS) of lung, liver and heart tissue; blood and lung samples for bacterial culture and molecular detection of viruses (including SARS-CoV-2) and bacteria. The cause of death attribution was undertaken by a multidisciplinary team and reported using World Health Organization framework for cause of death attribution. RESULTS: SARS-CoV-2 was identified on antemortem and/or postmortem sampling in 11.7% (20/171) of deceased children, including 13.2% (12/91) in whom MITS was done. Eighteen (90%) of 20 deaths with SARS-CoV-2 infection were <12 months age. COVID-19 was attributed in the causal pathway to death in 91.7% (11/12) and 87.5% (7/8) cases with and without MITS, respectively. Lung histopathologic features in COVID-19-related deaths included diffuse alveolar damage (n = 6, 54.5%), type 2 pneumocyte proliferation (n = 6, 54.5%) and hyaline membrane formation (n = 5, 36.4%). Culture-confirmed invasive bacterial disease was evident in 54.5% (6/11) of COVID-19 attributed deaths investigated with MITS. CONCLUSIONS: COVID-19 was in the causal pathway of 10.5% (18/171) of all childhood deaths under surveillance. The postmortem histopathologic features in fatal COVID-19 cases in children were consistent with reports on COVID-19 deaths in adults; although there was a high prevalence of invasive bacterial disease in the children.

The Emergence of SARS-CoV-2 Variant(s) and Its Impact on the Prevalence of COVID-19 Cases in the Nabatieh Region, Lebanon.

Background: An outbreak of an unknown respiratory illness caused by a novel coronavirus, SARS-CoV-2, emerged in the city of Wuhan in Hubei Province, China, in December 2019 and was referred to as coronavirus disease-2019 (COVID-19). Soon after, it was declared as a global pandemic by the World Health Organization (WHO) in March 2020. SARS-CoV-2 mainly infects the respiratory tract with different outcomes ranging from asymptomatic infection to severe critical illness leading to death. Different SARS-CoV-2 variants are emerging of which three have raised concerns worldwide due to their high transmissibility among populations. Objective: To study the prevalence of COVID-19 in the region of Nabatieh-South Lebanon during the past year and assess the presence of SARS-CoV-2 variants and their effect on the spread of infection during times of lockdown. Methods: In our study, 37,474 nasopharyngeal swab samples were collected and analyzed for the detection of SARS-CoV-2 virus in suspected patients attending a tertiary health care center in South Lebanon during the period between 16 March 2020 and 21 February 2021. Results: The results demonstrated a variation in the prevalence rates ranging from less than 1% during full lockdown of the country to 8.4% upon easing lockdown restrictions and reaching 27.5% after the holidays and 2021 New Year celebrations. Interestingly, a new variant(s) appeared starting January 2021 with a significant positive association between the prevalence of positive tests and the percentage of the variant(s). Conclusions: Our results indicate that the lockdown implemented by the Lebanese officials was an effective intervention to contain COVID-19 spread. Our study also showed that lifting lockdown measures during the holidays, which allowed indoor crowded gatherings to occur, caused a surge in COVID-19 cases and rise in the mortality rates nationwide. More importantly, we confirmed the presence of a highly transmissible SARS-CoV-2 variant(s) circulating in the Lebanese community from at least January 2021 onwards.

PIGG variant pathogenicity assessment reveals characteristic features within 19 families.

PURPOSE: Phosphatidylinositol Glycan Anchor Biosynthesis, class G (PIGG) is an ethanolamine phosphate transferase catalyzing the modification of glycosylphosphatidylinositol (GPI). GPI serves as an anchor on the cell membrane for surface proteins called GPI-anchored proteins (GPI-APs). Pathogenic variants in genes involved in the biosynthesis of GPI cause inherited GPI deficiency (IGD), which still needs to be further characterized. METHODS: We describe 22 individuals from 19 unrelated families with biallelic variants in PIGG. We analyzed GPI-AP surface levels on granulocytes and fibroblasts for three and two individuals, respectively. We demonstrated enzymatic activity defects for PIGG variants in vitro in a PIGG/PIGO double knockout system. RESULTS: Phenotypic analysis of reported individuals reveals shared PIGG deficiency-associated features. All tested GPI-APs were unchanged on granulocytes whereas CD73 level in fibroblasts was decreased. In addition to classic IGD symptoms such as hypotonia, intellectual disability/developmental delay (ID/DD), and seizures, individuals with PIGG variants of null or severely decreased activity showed cerebellar atrophy, various neurological manifestations, and mitochondrial dysfunction, a feature increasingly recognized in IGDs. Individuals with mildly decreased activity showed autism spectrum disorder. CONCLUSION: This in vitro system is a useful method to validate the pathogenicity of variants in PIGG and to study PIGG physiological functions.

Treatment Patterns, Effectiveness, and Satisfaction Among Patients with Type 2 Diabetes Treated with Insulin in Saudi Arabia: Results of the RIMODIS Study.

INTRODUCTION: The alarming increase in type 2 diabetes mellitus (T2DM) in Saudi Arabia is aggravated by increasing obesity, sedentary lifestyle, and population aging. The RIMODIS study aimed at describing the practices in the therapeutic management of patients with T2DM treated with different insulin regimens. METHODS: This national, multicenter, non-interventional, cross-sectional disease registry on the real-life therapeutic management of insulin-treated patients with T2DM in Saudi Arabia enrolled 3010 patients. It primarily aimed at describing treatment patterns, complications, and glycemia levels. Patients completed the diabetes treatment satisfaction questionnaire (DTSQ). Data on different treatment patterns were analyzed using chi-square or Fisher's exact test. Outcomes were analyzed according to the different insulin regimen subgroups (basal versus premixed). RESULTS: Over 60% of patients were treated with premixed insulin and most patients were also prescribed oral antidiabetics (OADs). Patients on insulin alone seemed to achieve better glycated hemoglobin (HbA1c) control. Adding OADs to insulin slightly increased treatment satisfaction scores, with scores higher in patients on basal insulin compared to premixed insulin. Hypoglycemia was lower when adding OADs to insulin. Most patients showed high treatment adherence; however, two-thirds of study patients failed to achieve glycemic target levels. CONCLUSION: Most patients are treated with a combination of insulin and OADs, associated with glycemic control and low incidence of hypoglycemia. However, we highlight suboptimal glycemic target achievement, underscoring the need to improve T2DM clinical management and promote healthier lifestyle among patients in Saudi Arabia.

Clinical use of neuro-imaging in psychiatric patients at the Charlotte Maxeke Johannesburg Academic Hospital.

BACKGROUND: Neuro-imaging is relatively new in psychiatry. Although the actual role of neuro-imaging in psychiatry remains unclear, it is used to strengthen clinical evidence in making psychiatric diagnoses. AIM: To analyse the records of inpatients referred for neuro-imaging (computerised tomography [CT] and/or magnetic resonance imaging [MRI] scans) to determine the proportion of abnormal neuro-imaging results and, if any, factors associated with abnormal neuro-imaging results. SETTING: This study was conducted at the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) situated in Johannesburg, South Africa. METHODS: This was a quantitative retrospective record review. All adult psychiatric inpatients who had undergone a CT and/or MRI scan during 01 January 2014 to 31 December 2015 were included. Out-patients or patients admitted in the medical wards were excluded from the study. All neuro-imaging referrals were identified from hospital records and their demographics, scan characteristics and diagnoses were subsequently captured. RESULTS: A total of 1040 patients were admitted to the CMJAH psychiatric unit, of which 213 (20.5%) underwent neuro-imaging tests. Of the 213 scans performed, 74 were abnormal, representing a yield of 34.7%. The most common reported pathology was atrophy (n = 22, 29.7%). There was no statistically significant association between age group (χ 2 = 3.9, p = 0.8), gender (χ 2 = 1.3; p = 0.5), psychiatric diagnoses and abnormal scans. However, there were trends towards an association with comorbid HIV infection (χ 2 = 3.476, p = 0.062) and comorbid substance abuse (χ 2 = 2.286, p = 0.091). CONCLUSION: This study supports the need for clear clinical indications to justify the cost-effective use of neuro-imaging in psychiatry. This study's high yield of abnormal CT scans, although similar to other studies, advocates that HIV positive testing and the presence of focal neurological signs will improve the yield further.

Mental illness attitudes and knowledge in non-specialist medical doctors working in state and private sectors.

BACKGROUND: An increasing number of South Africans utilise primary healthcare services (either in the state or private sector) for mental health concerns; hence, there is a need to objectively assess these doctors' attitudes and knowledge of mental illness. AIM: To investigate aspects of knowledge and attitudes towards mental illness of a group of private and state-employed non-specialist medical doctors. METHOD: Doctors in the state sector who were working at a primary healthcare level and who were not working towards, or did not hold, a specialist qualification were considered eligible for the study. Doctors in the private sector who were working as general practitioners and who did not hold a specialist qualification were considered eligible for the study. Data were collected by means of a self-administered questionnaire. A link to the study questionnaire, information about the study, details of the researcher and matters pertaining to informed consent were emailed to potential participants. RESULTS: Of the 140 practitioners who responded to the survey, 51.4% (n = 72) worked in the state sector, 41.4% (n = 58) worked in the private sector and 7.1% (n = 10) worked in both the state and private sectors (χ2 1 = 45.31, p < 0.010). The majority (> 50%) of participants in all three groups had a positive attitude towards mental illness (χ2 2 = 1.52, p = 0.468). Although there were no significant associations between attitude and socio-demographic characteristics (p > 0.05), male SS doctors reported feeling less comfortable when dealing with mentally ill patients (p = 0.015); SS doctors who did not have family contact with mental illness were less likely to feel that mentally ill patients did not pose a risk to others (p = 0.007), and PS doctors under the age of 35 years were more likely to feel adequately trained to treat mental illness (p = 0.026). The majority (> 50%) of participants in all three groups had an adequate level of knowledge of mental illness (modal scores = 10). There were no significant associations between knowledge and socio-demographic characteristics (p > 0.05). CONCLUSION: Despite the findings of a positive attitude and adequate knowledge of mental illness amongst the participants of this study, it is recommended that more targeted interventions are established to further improve mental health awareness and knowledge of doctors at both undergraduate and postgraduate levels of study.

Temporal trends in between and within-country inequalities in caesarean delivery in low- and middle-income countries: a Bayesian analysis.

OBJECTIVE: To provide updated information about between-country variations, temporal trends and changes in inequalities within countries in caesarean delivery (CD) rates. DESIGN: Cross-sectional study of Demographic and Health Survey (DHS) during 1990-2018. SETTING: 74 low- and middle-income countries (LMICs). POPULATION: Women 15-49 years of age who had live births in the last 3 years. METHODS: Bayesian linear regression analysis was performed and absolute differences were calculated. MAIN OUTCOME MEASURE: Population-level CD by countries and sociodemographic characteristics of mothers over time. RESULTS: CD rates, based on the latest DHS rounds, varied substantially between the study countries, from 1.5% (95% CI 1.1-1.9%) in Madagascar to 58.9% (95% CI 56.0-61.6%) in the Dominican Republic. Of 62 LMICs with at least two surveys, 57 countries showed a rise in CD during 1990-2018, with the greatest increase in Sierra Leone (19.3%). Large variations in CD rates were observed across mother's wealth, residence, education and age, with a higher rate of CD by the richest and urban mothers. These inequalities have widened in many countries. Stratified analyses suggest greater provisioning of CD by the richest mothers in private facilities and poorest mothers in public facilities. CONCLUSIONS: CD rates varied substantially across geographical locations and over time, irrespective of public or private health facilities. Changes in CD rates continue across wealth, place of residence, education, and age of mother, and are widening in most study countries. TWEETABLE ABSTRACT: Increasing caesarean delivery rates were greater among the richest and urban mothers than their counterparts, with widened gaps in LMICs.
