The Lagos State COVID-19 Think-tank, a Potential Framework for Decision-making in a Pandemic Era.

Lagos state remains the epicenter of COVID-19 infection in Nigeria. To facilitate the emergency preparedness and response to COVID-19, the State Governor and Incident Commander constituted a Think Tank comprising 13 experts from various disciplines committed to the health of the public. The Think Tank assisted the government with decision-making strategies and supported the emergency operation centre (EOC) for the COVID-19 response. Their main achievements were developing frameworks for decision-making and strategies for phased easing of the State-wide lockdown. The challenges encountered were that it was often viewed as a parallel structure to the EOC and separated from the traditional civil service structure; causing some reluctance to implement ideas generated by the Think Tank. Nevertheless, the Think Tank played an important role during the COVID-19 pandemic; the lessons learned might help other states and resource-limited countries wishing to adopt this approach to emergency response.

RésuméL'État de Lagos reste l'épicentre de l'infection au COVID-19 au Nigeria. Pour faciliter la préparation et la réponse aux situations d'urgence (EPR) face au COVID-19, le gouverneur de l'État a constitué un groupe de réflexion composé de 13 experts de diverses disciplines. Le concept du groupe de réflexion était d'impliquer le secteur privé et le milieu universitaire dans la réponse COVID de l'État de Lagos, reconnaissant qu'un résultat réussi de l'EPR nécessite une expertise dont certaines n'existaient pas au sein de la fonction publique. Le Think Tank a aidé le gouvernement à élaborer des stratégies de prise de décision et a soutenu le centre des opérations d'urgence (COU) pour la réponse à la COVID-19. Leurs principales réalisations ont été l'élaboration de cadres de prise de décision et de stratégies d'assouplissement progressif du confinement à l'échelle de l'État. Les défis rencontrés étaient qu'il était souvent considéré comme une structure parallèle à l'EOC et séparé de la structure traditionnelle de la fonction publique; provoquant une certaine réticence à mettre en œuvre les idées générées. Le groupe de réflexion de l'État de Lagos a démontré un modèle réussi de partenariat public-privé dans le domaine de la santé mis en œuvre par une diversité d'acteurs dans des secteurs critiques. Cela pourrait être considéré comme un modèle utile pour faire face à une myriade de crises similaires auxquelles le secteur de la santé est souvent confronté. Les enseignements tirés pourraient aider d'autres États et pays aux ressources limitées souhaitant adopter cette approche dans les interventions d'urgence.

Spatial and temporal analysis of road traffic crashes and ambulance responses in Lagos state, Nigeria.

BACKGROUND: Sub-Saharan African countries, Nigeria inclusive, are constrained by grossly limited access to quality pre-hospital trauma care services (PTCS). Findings from pragmatic approaches that explore spatial and temporal trends of past road crashes can inform novel interventions. To improve access to PTCS and reduce burden of road traffic injuries we explored geospatial trends of past emergency responses to road traffic crashes (RTCs) by Lagos State Ambulance Service (LASAMBUS), assessed efficiency of responses, and outcomes of interventions by local government areas (LGAs) of crash. METHODS: Using descriptive cross-sectional design and REDcap we explored pre-hospital care data of 1220 crash victims documented on LASAMBUS intervention forms from December 2017 to May 2018. We analyzed trends in days and times of calls, demographics of victims, locations of crashes and causes of delayed emergency responses. Assisted with STATA 16 and ArcGIS pro we conducted descriptive statistics and mapping of crash metrics including spatial and temporal relationships between times of the day, seasons of year, and crash LGA population density versus RTCs incidence. Descriptive analysis and mapping were used to assess relationships between 'Causes of Delayed response' and respective crash LGAs, and between Response Times and crash LGAs. RESULTS: Incidences of RTCs were highest across peak commuting hours (07:00-12:59 and 13:00-18:59), rainy season and harmattan (foggy) months, and densely populated LGAs. Five urban LGAs accounted for over half of RTCs distributions: Eti-Osa (14.7%), Ikeja (14.4%), Kosofe (9.9%), Ikorodu (9.7%), and Alimosho (6.6%). On intervention forms with a Cause of Delay, Traffic Congestion (60%), and Poor Description (17.8%), had associations with LGA distribution. Two densely populated urban LGAs, Agege and Apapa were significantly associated with Traffic Congestion as a Cause of Delay. LASAMBUS was able to address crash in only 502 (36.8%) of the 1220 interventions. Other notable outcomes include: No Crash (false calls) (26.6%), and Crash Already Addressed (22.17%). CONCLUSIONS: Geospatial analysis of past road crashes in Lagos state offered key insights into spatial and temporal trends of RTCs across LGAs, and identified operational constraints of state-organized PTCS and factors associated with delayed emergency responses. Findings can inform programmatic interventions to improve trauma care outcomes.

Gender difference in the point prevalence, symptoms, comorbidity, and correlates of depression: findings from the Lagos State Mental Health Survey (LSMHS), Nigeria.

It is still unclear whether the gender difference in the rate of depression cuts across cultures or is specific to some depressive symptoms. This study evaluated the gender difference in current prevalence, symptoms, comorbidity, and correlates of depression in Lagos, Nigeria. A total of 11,246 adult participants (6525 females and 4712 males) in a face-to-face household survey were assessed for symptoms of depression. They were also assessed for symptoms of anxiety, somatic symptoms, alcohol and substance use disorders, and disability. The difference between the point prevalence for symptoms of depression in females (6.3%, s.e 0.3) and males (4.4%, s.e 0.3) was significant (OR 1.28, 95% CI 1.14-1.59). Compared to males, females had significantly higher rates for anhedonia (OR 1.20), hypersomnia (OR 2.15), fatigue (OR 1.49), guilt/worthless feeling (OR 1.41), poor concentration (OR 1.32), psychomotor retardation (OR 1.51), and suicidal ideation (OR 1.32). However, poor appetite (OR 0.69) and comorbidity with alcohol use (OR 0.25) was significantly lower in females compared to males. The significantly higher rates for depression in females were only restricted to below 45 years and higher socioeconomic status. Our study further contributed to the growing literature suggesting that the gender differences in rates of depression not only cut across many cultures, but most pronounced with atypical symptoms, not affected by recall bias and seems to disappear with increasing age. These need to be considered when formulating mental health policies for equitable and acceptable health services.

Current prevalence, comorbidity and associated factors for symptoms of depression and generalised anxiety in the Lagos State Mental Health Survey (LSMHS), Nigeria.

BACKGROUND: Depression and anxiety are very prevalent, highly co-morbid, burdensome with huge treatment gaps in low and middle-income countries (LMICs). This study aimed to estimate the current prevalence of symptoms of depression and generalised anxiety, examine co-morbid conditions and associated sociodemographic factors in Lagos state, Nigeria. METHODS: A face to face household survey completed by 11,246 adult participants (age 18-75years). Clinically significant symptoms of depression, generalised anxiety and somatic symptoms were assessed using the specific modules of the Patient Health Questionnaire (PHQ) respectively. Alcohol use, substance use and disability were assessed with the Alcohol Use Disorders Identification Test-short form (AUDIT-C), the Mini International Neuropsychiatric Interview (M.I.N.I) and the WHO Disability Assessment Schedule (WHODAS 2.0) respectively. RESULTS: The mean age was 36.75 (sd 12.3) years and there were 6525 (58.0%) females. The weighted current prevalence of symptoms of depression, generalised anxiety and combined depression/generalised anxiety were 5.5% (se 0.3), 3.5% (se 0.2) and 1.2% (se 0.1) respectively. About 20.9% of all cases of depressive symptoms have co-morbidity with symptoms of generalised anxiety. Symptoms of depression and generalised anxiety had high co-morbidity with somatic symptoms, alcohol use problems and disability but not substance use disorders. Being female, not married (especially separated/divorced or widowed) and unemployment were significantly associated with presence of either symptoms of depression or generalised anxiety. CONCLUSION: Our findings suggest that despite the popularity of cross-national surveys, there is need for individual countries and states to generate complimentary local data to plan effective local response to close the huge treatment gap for common mental disorders.

Primary health care workers' knowledge and attitudes towards depression and its management in the MeHPric-P project, Lagos, Nigeria.

OBJECTIVE: This study aimed to evaluate the knowledge, perceived challenges and attitude of primary health care (PHC) workers in Lagos to depression and its management in the PHC. METHODS: Health workers (n=607) from 49 "flagship" PHCs in Lagos were evaluated for their level of knowledge, experience, competence, attitude and perceived challenges to managing depression in the primary care using a case vignette. RESULTS: More than half (56.2%) of the health workers correctly diagnosed depression. The most endorsed causative factors were "Psycho-social" (77.3%), but "spiritual factors" were endorsed by 36.2%. While only 39.4% agreed that the depressed patient is best managed in a PHC, 86.2% would support treating the patient in their PHC if their capacity is enhanced. Top identified challenges were "heavy work schedule" (68.5%) and "lack of competence of the PHC staff" (67.5%). Over 42% had poor attitude towards depressed patient. Having a mental health training was the major factor that predicted good knowledge (OR 4.52, 95%CI 2.96-7.00) and good attitude (OR 2.17, 95% CI 1.48-3.17). CONCLUSIONS: For successful scale up of mental health services in LMICs, the design of mental health training curriculum for PHC workers should consider their knowledge, experience, competence level, perception and attitudes.

Prevalence and associated factors for suicidal ideation in the Lagos State Mental Health Survey, Nigeria.

BACKGROUND: To combat the increasing rate of suicide, basic data on suicidal behaviours reflecting the uniqueness of the locality are needed in sub-Saharan Africa. AIMS: To assess the prevalence of suicidal ideation and associated factors. METHOD: Adults (n=11 246) from the five administrative divisions of Lagos State completed questionnaires detailing suicidal ideation, socio-demographic details, common mental disorders (depression, anxiety and somatic symptoms), alcohol and psychoactive substance use disorders and disability. RESULTS: The weighted prevalence of current suicidal ideation was 7.28% (s.e. 0.27). Independently associated factors were older age, being female, not married, low occupational group, depression, anxiety, somatic symptoms and disability. CONCLUSIONS: Despite the validity of cross-national surveys, there is need for individual countries to generate complementary local data to explain variability in rates and risk factors in order to plan for suicide prevention or develop timely and effective response.

Macrostomia: a study of 15 patients seen in Lagos, Nigeria and proposal for a classification of severity.

We made a descriptive epidemiological study of patients who presented with isolated macrostomia during a mass screening programme and repair of orofacial cleft deformities in Lagos, Nigeria. Detailed histories of environmental, gestational, and hereditary factors that may contribute to the malformation were taken, and physical examinations and specialist consultations to detect associated congenital malformations were made. Three patients had unilateral macrostomia and in 12 it was bilateral and symmetrical. The mean (SD) age was 8 (2) years, range 3 months to 32 years. There were 6 men and 9 women. Two women and one man had unilateral macrostomia; the two women presented with right sided involvement, while the man had left sided involvement. The commonest associated malformation was a low-set ear (n = 7). Other patients had combinations of congenital malformations. The mean (SD) age of the mothers at conception was 24 (1) years, range 18 to 32 years, while those of the fathers during the periods of conception were 35 (1) years, range 26 to 45. No gestational or environmental factors were detected in the history. One mother with unilateral presentation had a child with bilateral deformities.

Left ventricular mass measured by myocardial perfusion gated SPECT. Relation to three-dimensional echocardiography.

PURPOSE: The purpose of this investigation was to determine whether left ventricular mass (LVM) assessed from myocardial perfusion gated SPECT (GSPECT) data corresponds with echocardiographic estimates, and whether mass accuracy decreases as relative myocardial wall thickness increases. MATERIALS AND METHODS: Myocardial perfusion tomograms were selected retrospectively for 37 patients, of whom 18 had Tl-201 and 19 had Tc-99m sestamibi GSPECT poststress data collections, which were subsequently processed using quantitative gated SPECT software (Cedars Sinai Medical Center, Los Angeles, CA). These patients also had clinically indicated echocardiograms for assessment of wall thickness and possible valvular involvement. In addition, LV internal diameter and posterior wall thickness were measured at end-diastole by two-dimensional guided M-mode echocardiography to assess relative myocardial wall thickness, and LVM was measured by three-dimensional echocardiography using an acoustic spatial locator device. RESULTS: LVM values were not significantly different between GSPECT and three-dimensional echocardiography (153 +/- 39 g versus 146 +/- 35 g, respectively; P = NS). GSPECT correlated significantly (r = 0.63, P < 0.0001) with three-dimensional echocardiography, with a mean difference of 7 +/- 32 g but a substantial root mean squared error of 31 g. Results were similar for similar mass ranges when subgrouped by isotope and by the presence of significant myocardial perfusion defects. Results were independent of relative myocardial wall thickness determined by two-dimensional echocardiography. The two methods yielded similar results in the highest mass range of 400 to 500 g. CONCLUSIONS: GSPECT and three-dimensional echo LVM correlated significantly, but given the large spread of statistical errors, these two techniques should not be considered interchangeable. Because gamma camera resolution is limited, GSPECT LVM should be viewed as an approximation.

Positron emission tomography, echo-doppler, and exercise studies of functional capacity in hypertensive heart disease.

BACKGROUND: This study examines the relationship between functional capacity, left ventricular diastolic function, and myocardial perfusion reserve (MPR) in patients with left ventricular hypertrophy (LVH). METHODS: We studied 16 patients with LVH and 10 controls. Functional capacity was assessed by cardiopulmonary exercise, MPR by positron emission tomography, and left ventricular diastolic function by echo-Doppler. RESULTS: Functional capacity and MPR were significantly lower in the patients. Functional capacity correlated positively with MPR and left ventricular diastolic function. CONCLUSIONS: Diminished functional capacity in patients with hypertension-induced LVH is related to the impairment in MPR and left ventricular diastolic function.
