The Effect of Music on Operative Anxiety markers in patients undergoing Cataract Surgery: Adual centre cross-sectional comparative study.

OBJECTIVE: To determine the effect of intraoperative music on various markers of anxiety among adult patients undergoing small incision cataract surgery. METHODS: This was a hospital-based, age-sex matched, comparative cross-sectional study of consenting 144 adult participants aged 46 years and above with operable, age-related cataracts undergoing small incision cataract surgery under local anaesthesia in two ophthalmic centres. All participants were allotted into two equal groups consisting of 72 participants in the experimental group (exposed to music of their choice) and 72 participants in the control group (no music exposure). Blood pressure, pulse rate and salivary cortisol assay levels were measured. Data obtained were analyzed using statistical package for social sciences (IBM SPSS version 23.0). RESULTS: One hundred and forty-four participants with total male-to-female ratio of 1:2.1 were studied. Gender ratio was 1:2.3 and 1:2.0 and the median age (Q1-Q3) of 65.00 (55.5-71.5) years and 65.50 (56.5-72.0) years for music and non-music groups respectively. Participants in the music group showed a statistically significant reduction in systolic blood pressure, diastolic blood pressure and pulse rate (p < 0.05) except at baseline. The mean value salivary cortisol level showed a statistically significant decrease in both groups from baseline for music (23.91ng/ml) and nonmusic (19.12ng/ml) group (p<0.001) respectively. Similarly, participants in the music group showed a statistically significant reduction of Spielberger State anxiety score after music intervention compared to control (p<0.001). CONCLUSIONS: This study demonstrated the effectiveness of music in decreasing anxiety indicators during cataract surgery with markers like salivary cortisol assay, pulse rate, systolic and diastolic blood pressure.

OBJECTIF: Déterminer l'effet de la musique intra-opératoire sur divers marqueurs d'anxiété chez les patients adultes subissant une chirurgie de la cataracte par petite incision. MÉTHODES: Il s'agissait d'une étude transversale comparative, basée à l'hôpital, appariée selon l'âge et le sexe, portant sur 144 participants adultes consentants âgés de 46 ans et plus, présentant des cataractes liées à l'âge opérables et subissant une chirurgie de la cataracte par petite incision sous anesthésie locale dans deux centres ophtalmologiques. Tous les participants ont été répartis en deux groupes égaux, soit 72 participants dans le groupe expérimental (exposé à de la musique de leur choix) et 72 participants dans le groupe témoin (pas d'exposition à la musique). La pression artérielle, la fréquence cardiaque et les taux de cortisol salivaire ont été mesurés. Les données obtenues ont été analysées à l'aid du logiciel statistique pour les sciences sociales (IBM SPSS version 23.0). RÉSULTATS: Cent quarante-quatre participants avec un rapport total d'hommes à femmes de 1:2,1 ont été étudiés. Le ratio hommes-femmes était de 1:2,3 et 1:2,0, avec un âge médian (Q1-Q3) de 65,00 (55,5-71,5) ans et 65,50 (56,5-72,0) ans pour les groupes musique et non-musique, respectivement. Les participants du groupe musique ont montré une réduction statistiquement significative de la pression artérielle systolique, de la pression artérielle diastolique et de la fréquence cardiaque (p < 0,05) sauf au départ. La valeur moyenne du taux de cortisol salivaire a montré une diminution statistiquement significative dans les deux groupes par rapport au départ pour le groupe musique (23,91 ng/ml) et le groupe non-musique (19,12 ng/ml) (p <0,001) respectivement. De même, les participants du groupe musique ont montré une réduction statistiquement significative du score d'anxiété à l'état de Spielberger après l'intervention musicale par rapport au groupe témoin (p <0,001). CONCLUSIONS: Cette étude a démontré l'efficacité de la musique dans la diminution des indicateurs d'anxiété pendant la chirurgie de la cataracte, avec des marqueurs tels que le dosage du cortisol salivaire, la fréquence cardiaque, la pression artérielle systolique et diastolique.

Clinical predictors of Covid-19 mortality in a tertiary hospital in Lagos, Nigeria: A retrospective cohort study.

Background: The predictors of mortality among patients presenting with severe to critical disease in Nigeria are presently unknown. Aim: The aim of this study was to identify the predictors of mortality among patients with COVID-19 presenting for admission in a tertiary referral hospital in Lagos, Nigeria. Patients and Methods: The study was a retrospective study. Patients' sociodemographics, clinical characteristics, comorbidities, complications, treatment outcomes, and hospital duration were documented. Pearson's Chi-square, Fischer's Exact test, or Student's t-test were used to assess the relationship between the variables and mortality. To compare the survival experience across medical comorbidities, Kaplan Meir plots and life tables were used. Univariable and multivariable Cox-proportional hazard analyses were conducted. Results: A total of 734 patients were recruited. Participants' age ranged from five months to 92 years, with a mean ± SD of 47.4 ± 17.2 years, and a male preponderance (58.5% vs. 41.5%). The mortality rate was 9.07 per thousand person-days. About 73.9% (n = 51/69) of the deceased had one or more co-morbidities, compared to 41.6% (252/606) of those discharged. Patients who were older than 50 years, with diabetes mellitus, hypertension, chronic renal illness, and cancer had a statistically significant relationship with mortality. Conclusion: These findings call for a more comprehensive approach to the control of non-communicable diseases, the allocation of sufficient resources for ICU care during outbreaks, an improvement in the quality of health care available to Nigerians, and further research into the relationship between obesity and COVID-19 in Nigerians.

Oxidative stress markers and genetic polymorphisms of glutathione S-transferase T1, M1, and P1 in a subset of children with autism spectrum disorder in Lagos, Nigeria.

BACKGROUND: The role of oxidative stress has been identified in the development of autism spectrum disorder (ASD), and polymorphisms of glutathione S-transferase have been associated with some diseases linked to oxidative stress. Hence, we evaluated the serum levels of oxidative stress markers and investigated genetic polymorphisms of glutathione S-transferase associated with autism. MATERIALS AND METHODS: Forty-two children clinically diagnosed with ASD using the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) criteria and a clinical interview were included in the study. Twenty-three age-matched controls without any known genetic/developmental disorder were also recruited. Oxidative stress markers along with the genetic polymorphisms of glutathione S-transferase were determined. RESULTS: Reduced glutathione in ASD patients was significantly lower than the control (P = 0.008), whereas other oxidative stress markers measured were not significantly different in both the control and case populations. The frequencies of GSTT1 and GSTM1 null genotypes were lower among the controls compared with the cases, however, no association risk was observed. The observed risk of carrying Val/Val genotype among the cases was approximately six times that of the controls. CONCLUSION: Individuals with ASD showed a significant diminished level of reduced glutathione, however, the distribution of GSTT1, GSTM1, and GSTP1 polymorphisms was not found to be associated with autism in this study population.

Psychiatric morbidity in hypertensives attending a cardiology outpatient clinic in West Africa.

OBJECTIVES: To determine kinds of psychiatric morbidity among a sample of stable hypertensive outpatients in a teaching hospital. MATERIALS AND METHODS: A cross-sectional study of 260 enrolled outpatients. Psychiatric morbidity was assessed using a 2-stage evaluation method with the General Health Questionnaire Version 12 (GHQ-12) and Structured Clinical Interview for DSM-IV (SCID) to assess for psychiatric diagnosis. RESULTS: 28 (10.8%) of the 260 patients endorsed some psychological distress, with a mean GHQ-12 score of ≥ 2. At the second stage, 16.1% (N=13 of 81) interviewed had one or more psychiatric disorder on the SCID. The commonest psychiatric diagnosis made were mood disorders, with current major depressive disorder occurring at a rate of 6.2%. Other disorders found were past major depressive episode (2.5%), organic mood syndrome (3.7%), and somatoform disorder (3.7%). CONCLUSION: The relationship between hypertension and mood disorders should inform a higher index of suspicion among physicians and general practitioners in order to give patients appropriate treatments or referrals where necessary. It is recommended that collaboration with mental health service providers be encouraged.

Recognition of Autism Spectrum Disorder (ASD) symptoms and knowledge about some other aspects of ASD among final year medical students in Nigeria, Sub-Saharan Africa.

BACKGROUND: Earlier studies suggest that knowledge about Autism Spectrum Disorder (ASD) among healthcare workers in Nigeria is low. This present study assessed the knowledge of Nigerian final year medical students about symptoms of ASD and some other aspects of ASD. This is a cross sectional descriptive study that drew a total of seven hundred and fifty-seven (757) final year medical students from ten (10) randomly selected fully accredited medical schools out of a total of twenty-seven (27) fully accredited medical schools in Nigeria. Sociodemographic and Knowledge about Childhood Autism among Health Workers (KCAHW) questionnaires were used to assess knowledge of final year medical students about ASD and obtain demographic information. RESULTS: Only few, 218 (28.8 %) of the 757 final year medical students had seen and participated in evaluation and management of at least a child with ASD during their clinical postings in pediatrics and psychiatry. Knowledge and recognition of symptoms of ASD is observed to be better among this group of final year medical students as shown by higher mean scores in the four domains of KCAHW questionnaire. Knowledge about ASD varies across gender and regions. Misconceptions about ASD were also observed among the final year medical students. CONCLUSIONS: More focus needs to be given to ASD in the curriculum of Nigerian undergraduate medical students, especially during their psychiatry and pediatric clinical postings.

Burden and psychological effects: caregiver experiences in a psychiatric outpatient unit in Lagos, Nigeria.

OBJECTIVE: Worldwide, research into experiences of care givers are gradually increasing and their central role in community care is being acknowledged. Caregivers experience a multidimensional range of problems, often associated with their caregiving role. It becomes important to identify these areas of burden and provide necessary support. The study sought to determine the prevalence of psychological distress and experience of burden of care among the caregivers of mentally ill patients. METHOD: A cross sectional descriptive study. Eligible consecutive subjects were recruited to the study over a 6 month period. Fifty three caregiver relatives of patients diagnosed with a psychiatric illness were assessed using the General Health questionnaire version 12, an Adapted Burden of Care (BOC) Schedule and a Sociodemographic questionnaire. RESULTS: The caregivers were 51% male and 49% female. Most were above 35years in age (66.1%). They were either parents (38.8%), siblings (18.4%), uncle/aunt (14.3%), first cousin (12.2%) or other extended relatives (16.3%). Almost half of the relatives had psychological distress (43.8%) and most of which (63%) had more burden. The mean score on the BOC among the caregivers was 41 (±18.68SD), with scores ranging from 0.00-89.00, and 45.3% of relatives experiencing more than average burden of care. CONCLUSION: There is a significant level of burden and psychological distress experienced by caregivers in this study location. It is recommended that effectively planned interventions are targeted at alleviating this burden and at improving the ability of caregivers to cope, within the Nigerian mental health service delivery system.

Efficacy of visual inspection of the cervix using acetic acid in cervical cancer screening: a comparison with cervical cytology.

Screening programmes for the early detection of premalignant lesions of the cervix are expensive and technically difficult, especially in resource-challenged settings. There is a need for cheaper and equally effective alternative screening methods. This study compared the efficacy of visual inspection of the cervix using acetic acid (VIA) with the Pap smear method. A total of 186 subjects had a Pap smear followed by visual inspection of the cervix using 3 - 5% acetic acid with biopsies taken from suspicious acetowhite positive lesions. Cases of abnormal cytology were recalled for biopsies. A total of 150 subjects were negative for both tests; 30 (16.2%) were positive for VIA, while six were positive for both VIA and Pap smear. VIA detected one lesion missed by Pap smear on biopsy. The sensitivity of VIA was 100%, while that of Pap smear was 85.7%. The negative predictive value of VIA was 100%, while the positive predictive value was 20%. The sensitivity of VIA equals the reported rates for Pap smear. VIA is proposed as a credible alternative to Pap smear in resource-challenged settings.
