Malaria and COVID-19 share striking similarities in their symptoms. A cross-sectional randomized study was conducted to investigate the role of sex in the coinfection of malaria and COVID-19 as well as some associated factors in Rivers State, Nigeria. Ethical approval was obtained from the Rivers State Health and Ethics Committee before the commencement of this study, and the study was conducted at the COVID-19 Treatment Center Medical Laboratory, Rivers State, Nigeria. Intravenous blood samples from three hundred randomly selected consenting study participants were examined for species using Giemsa microscopy, while pretested questionnaires were used to obtain data on sex, risk factors, and symptoms. All data generated were analyzed statistically using the Chi-square test with a < 0.05 value considered significant. All study participants had species (100% prevalence) with varying parasite loads, and . was the only species observed. Study participants (irrespective of sex) with low and high parasitaemia had the highest and least prevalence, respectively ( > 0.05). Male study participants experienced more symptoms than females ( > 0.05) except for sore throat which had an equal value among males and females. Travel history was the only risk factor that showed significant association with sex, and males had a higher value than females ( < 0.05). Malaria and COVID-19 are major public health issues in Nigeria; more researches on these diseases especially in epidemiology, pathology, diagnosis, treatment, and vaccine production are vital.

It is a rarely reported variant. A 60-year-old gentleman presented with complaints of difficulty in swallowing, regurgitation and chest pain for the past 10 years. His symptoms persisted despite the use of proton pump inhibitors. On endoscopy and barium swallow, the diagnosis of vigorous achalasia was confirmed. It is a rare variant of classic achalasia usually misdiagnosed as diffuse oesophageal spasm. Increasing demand for magnetic resonance imaging (MRI) has contributed to extended patient waiting times worldwide. This is particularly true in resource-limited environments, prompting this institutional workflow analysis. To determine the 'pre-' and 'post-scan' times for normal-hour MRI studies conducted at a tertiary-level, public-sector South African hospital and to assess any association with demographic details, patient characteristics, anatomical site and scan parameters. A secondary objective was determination of the average daily MR 'down' time. A prospective descriptive study stratifying MRI workflow into 'pre-scan', 'scan', 'post-scan' and 'down' times. During 'pre-' and 'post-scan' times patients occupied the scanner whilst staff performed tasks indirectly contributing to image acquisition. During 'down' time no patient occupied the MRI room. 'Pre-' and 'post-scan' times were compared with demographic details, patient characteristics, anatomical site and study parameters, utilising correlation analysis or analysis of variance (ANOVA). A total of 223 patients ( = 223) underwent 286 investigations in the 23-day review period. Seventy per cent of routine working time was utilised in image acquisition. The 'pre-' and 'post-scan' times together accounted for 19% and 'down' time for 11% of working time. Prolonged 'pre-' and 'post-scan' times were independently associated with age less than 12 years, anaesthesia, sedation and immobility ( < 0.01 in all cases). The longest median combined 'pre-' and 'post-scan' time by anatomical site (cholangiopancreatography, 2146 min) was more than six times the shortest (pituitary fossa, 311 min). A critical analysis of magnetic resonance 'pre-' and 'post-scan' times can provide valuable insights into opportunities for enhanced service efficiency.

People living with HIV (PLWH) face new challenges such as accelerated ageing and higher rates of comorbidities including cardiovascular, renal and metabolic diseases as they age. To profile the demographic and clinical characteristics of elderly patients receiving HIV care at Newlands Clinic (NC), Harare, Zimbabwe, as of 01 October 2019. A cross-sectional analysis was conducted using clinic data. All patients who were 50 years and older on 01 October 2019 were enrolled. https://www.selleckchem.com/JAK.html Descriptive statistics (medians, interquartile ranges [IQRs] and proportions) were used to describe patient demographic and clinical characteristics. Out of 6543 patients undergoing care at NC, 1688 (25.8%) were older than 50 years. The median duration of antiretroviral therapy (ART) was 10.9 years (IQR 7.1-13). Over 90% of all patients had an HIV viral load below 50 copies/mL. Women were more likely than men to be overweight and obese (32% and 25% vs. 18% and 7%, respectively). Hypertension (41.2%), arthritis (19.9%) and chronic kidney disease (11.6%) were common comorbidities differently distributed based on sex. The most common malignancy diagnosed in women was cervical intra-epithelial neoplasia (68% of cancer burden in women) and Kaposi sarcoma was the leading malignancy in men (41% of cancer burden in men). Nearly 20% of patients had at least two chronic non-communicable comorbidities and 5.6% had at least three. A high burden of comorbidities was observed amongst HIV-positive elderly patients receiving ART. Age-appropriate monitoring protocols must be developed to ensure optimum quality of care for elderly HIV-positive individuals.
