Hypothermia in preterm infants admitted to low-resource neonatal units in northern Nigeria: an observational study of occurrence and risk factors.

BACKGROUND: Hypothermia is an important cause of morbidity and mortality among preterm and low-birth-weight neonates. In resource-constrained settings, limited referral infrastructure and technologies for temperature control potentiate preterm hypothermia. While there is some documentation on point-of-admission hypothermia from single center studies, there are limited multicenter studies on the occurrence of hypothermia among preterm infants in resource-limited-settings. Therefore, we conducted a multicenter study to determine the prevalence and risk factors for hypothermia at the time of admission and during the first 72 h after admission in northern Nigeria. METHOD: We carried out a prospective cohort study on preterm infants admitted to four referral hospitals in northern Nigerian between August 2020 and July 2021. We documented temperature measurements at admission and the lowest and highest temperatures in the first 72 h after admission. We also collected individual baby-level data on sociodemographic and perinatal history data. We used the World Health Organization classification of hypothermia to classify the babies' temperatures into mild, moderate, and severe hypothermia. Poisson regression analysis was used to identify risk factors for moderate-severe hypothermia. RESULTS: Of the 933 preterm infants enrolled, 682 (72.9%) had hypothermia at admission although the prevalence of hypothermia varied across the four hospitals. During the first 24 h after admission, 7 out of every 10 babies developed hypothermia. By 72 h after admission, between 10 and 40% of preterm infants across the 4 hospitals had at least one episode of moderate hypothermia. Gestational age (OR = 0.86; CI = 0.82-0.91), birth weight (OR = 8.11; CI = 2.87-22.91), presence of a skilled birth attendant at delivery (OR = 0.53; CI = 0.29-0.95), place of delivery (OR = 1.94 CI = 1.13-3.33) and resuscitation at birth (OR = 1.79; CI = 1.27-2.53) were significant risk factors associated with hypothermia. CONCLUSION: The prevalence of admission hypothermia in preterm infants is high and hypothermia is associated with low-birth-weight, place of delivery and presence of skilled birth attendant. The prevalence of hypothermia while in care is also high and this has important implications for patient safety and quality of patient care. Referral services for preterm infants need to be developed while hospitals need to be better equipped to maintain the temperatures of admitted small and sick newborns.

Adherence to malaria rapid diagnostic test result among healthcare workers in Sokoto metropolis, Nigeria.

BACKGROUND: Presumptive diagnosis and prescription of anti-malarial medicines to malaria rapid diagnostic test (RDT)-negative patients is a common practice among health care workers (HCWs) in Nigeria. There is paucity of data on HCWs adherence to RDT result in Sokoto metropolis, Nigeria. The study was conducted to determine HCWs adherence to malaria test result and the influencing factors. METHODS: A cross-sectional study was conducted among 262 HCWs selected by multistage sampling technique from primary and secondary health facilities in Sokoto metropolis. Data on demographic characteristics, adherence to RDT result and its influencing factors were collected from the HCWs. Adherence was categorized into good if adherence score is ≥ 4 and poor if otherwise. Chi-squared test was used to test association between adherence to test results and patients' fever presentation, expectation to be given anti-malarials, prior HCWs' case management training, among others. Independent predictors of adherence to RDT results were ascertained. RESULTS: Respondents' mean age was 33.5 ± 7.9 years, 190 (72.5%) worked in Primary Health Care facilities, 112 (42.8%) were Community Health Workers, 178 (67.9%) had National Diploma Certificate. The median years of practice was 5.0 (IQR: 3-10) years, while 118 (45.0%) had at most 4 years of practice. Overall, 211 (80.5%) had good adherence to RDT results. About 108 (89.3%) of HCWs who had training on malaria case management and 35 (89.7%) certificate holders had good adherence to RDT results. Predictors of adherence to test results were presence of fever in the patient [adjusted odds ratio (aOR): 2.53, 95% confidence interval (CI) 1.18-5.43], patients' expectation to be given anti-malarial medicines by the HCW (aOR: 3.06, 95% CI 1.42-6.58) and having been trained on malaria case management (aOR: 2.63; 95% CI 1.26-5.44). CONCLUSION: High level of adherence to RDT results among HCWs in Sokoto metropolis could be attributed to prior malaria case management training and HCWs' confidence in the national treatment guidelines. Continual training and supportive supervision of HCWs on malaria case management might optimize the current level of adherence to RDT results in Sokoto metropolis, Nigeria. Similarly, patients/caregivers' health education could aid better understanding of the need for anti-malarials thus reducing unnecessary demand.

Aicardi syndrome in a Nigerian female child: A case report and literature review of a rare neuro-developmental disorder from North-Western Nigeria.

Aicardi syndrome is a very rare neurodevelopmental disorder, inherited as an X-linked dominant condition with a triad of infantile spasm, partial or complete agenesis of the corpus callosum, and chorio-retinal "lacunae." We report a case of a female infant with the classical triad of Aicardi syndrome. A female infant presented to the Paediatric Neurology Clinic of the Federal Medical Centre Birnin-Kebbi, North-western Nigeria, at the age of two months with complaints of recurrent afebrile convulsions typical for infantile spasms. The patient was delivered at term with normal Apgar scores and anthropometry. Examination revealed an infant with no dysmorphic features and normal systemic examination. Magnetic Resonance Imaging (MRI) of the brain however, showed complete agenesis of the corpus callosum and dilatation of the posterior horn of the lateral and third ventricles. Fundoscopy showed multiple yellowish spots along the vascular arcades in the right eye. The left eye had a one-disc diameter lacuna in the superior nasal quadrant adjacent to the optic disc with multiple yellowish spots. A diagnosis of Aicardi syndrome was made. The child was placed on oral phenobarbital and followed up. At the age of 18 months, the child can only sit without support, hold an object in each hand, smile socially, and babble. The frequency of the seizures had also reduced from >100 episodes per day to 2-3 episodes per day, but the child had developed right-sided spastic hemiparesis. The patient was commenced on physiotherapy and the anti-epileptic drugs were maintained. We recommend clinicians consider Aicardi syndrome in the differential diagnosis of any child presenting with infantile spasms.

Clinical characteristics and predictors of human mpox outcome during the 2022 outbreak in Nigeria: a cohort study.

BACKGROUND: Research from sub-Saharan Africa that contributes to our understanding of the 2022 mpox (formerly known as monkeypox) global outbreak is insufficient. Here, we describe the clinical presentation and predictors of severe disease among patients with mpox diagnosed between Feb 1, 2022, and Jan 30, 2023 in Nigeria. METHODS: We did a cohort study among laboratory-confirmed and probable mpox cases seen in 22 mpox-treatment centres and outpatient clinics across Nigeria. All individuals with confirmed and probable mpox were eligible for inclusion. Exclusion criteria were individuals who could not be examined for clinical characterisation and those who had unknown mortality outcomes. Skin lesion swabs or crust samples were collected from each patient for mpox diagnosis by PCR. A structured questionnaire was used to document sociodemographic and clinical data, including HIV status, complications, and treatment outcomes from the time of diagnosis to discharge or death. Severe disease was defined as mpox associated with death or with a life-threatening complication. Two logistic regression models were used to identify clinical characteristics associated with severe disease and potential risk factors for severe disease. The primary outcome was the clinical characteristics of mpox and disease severity. FINDINGS: We enrolled 160 people with mpox from 22 states in Nigeria, including 134 (84%) adults, 114 (71%) males, 46 (29%) females, and 25 (16%) people with HIV. Of the 160 patients, distinct febrile prodrome (n=94, 59%), rash count greater than 250 (90, 56%), concomitant varicella zoster virus infection (n=48, 30%), and hospital admission (n=70, 48%) were observed. Nine (6%) of the 160 patients died, including seven (78%) deaths attributable to sepsis. The clinical features independently associated with severe disease were a rash count greater than 10 000 (adjusted odds ratio 26·1, 95% CI 5·2-135·0, p<0·0001) and confluent or semi-confluent rash (6·7, 95% CI 1·9-23·9). Independent risk factors for severe disease were concomitant varicella zoster virus infection (3·6, 95% CI 1·1-11·5) and advanced HIV disease (35·9, 95% CI 4·1-252·9). INTERPRETATION: During the 2022 global outbreak, mpox in Nigeria was more severe among those with advanced HIV disease and concomitant varicella zoster virus infection. Proactive screening, management of co-infections, the integration and strengthening of mpox and HIV surveillance, and preventive and treatment services should be prioritised in Nigeria and across Africa. FUNDING: None.
