Manometric Abnormalities in Patients With and Without Chronic Cough.

PURPOSE: This study examines the relationship between chronic cough and vagal hypersensitivity by measuring baseline esophageal motility, with interest in the upper esophageal sphincter (UES). MATERIALS AND METHODS: Patients undergoing workup for dysphagia were assigned to a chronic cough or control group based on self-reported symptoms. Differences in demographics, medical comorbidities, and high resolution esophageal manometry findings were obtained retrospectively. RESULTS: 62.5% of our cohort had chronic cough (30/48). There were no significant differences between the two groups with respect to sex, age, and race/ethnicity. Laryngopharyngeal reflux (LPR) was the only statistically significant predictor of CC (OR 74.04, p = 0.010). Cough patients had upper esophageal sphincter relaxation duration (734 ms) significantly longer than the non-cough patients (582 ms; p = 0.03), though both groups had similar upper esophageal mean basal pressure, mean residual pressure, relaxation time-to-nadir, and recovery time. No significant difference was found in the median intrabolus pressure and UES motility mean peak pressure between groups. CONCLUSION: Subtle differences in high-resolution manometry between patients with and without cough suggest, in line with previous studies, baseline alterations of upper esophageal function may manifest in patients with chronic cough through an undetermined mechanism that may include underlying vagal hypersensitivity. These findings encourage further manometric study examining the relationship between UES dysfunction and chronic cough.

Nursing Workforce Optimization Study: A Multi-method Evaluation and Process Improvement Intervention for HIV Service Delivery in Tanzania and Zambia.

ABSTRACT: Nurses are often suboptimally used in HIV care, due to misalignment of training and practice, workflow inefficiencies, and management challenges. We sought to understand nursing workforce capacity and support implementation of process improvement strategies to improve efficiency of HIV service delivery in Tanzania and Zambia. We conducted time and motion observations and task analyses at 16 facilities followed by process improvement workshops. On average, each nurse cared for 45 clients per day in Tanzania and 29 in Zambia. Administrative tasks and documentation occupied large proportions of nurse time. Self-reported competency was low at baseline and higher at follow-up for identifying and managing treatment failure and prescribing antiretroviral therapy. After workshops, facilities changed care processes, provided additional training and mentorship, and changed staffing and supervision. Efficiency outcomes were stable despite staffing increases. Collaborative approaches to use workforce data to engage providers in improvement strategies can support roll-out of nurse-managed HIV treatment.

Informal payments for primary health services in Zambia: Evidence from a health facility patient exit survey.

Although informal patient payments are a common feature of health systems in developing countries, little empirical evidence is available about the prevalence and magnitude of these payments in African health systems. The main objective of this study was to estimate the prevalence and determinants of informal patient payments in the Zambian health system. The study is based on a patient exit survey of 1900 patients that was conducted at government primary health facilities in three provinces in Zambia in 2018. We employ a two-part regression model to estimate first the determinants of the likelihood of incurring informal payments and the determinants of the amount paid. The results show that 6.2% of patients who visited government primary health facilities reported incurring informal payments. The average amount paid (ranging from US$ 1.41 to 3.36) can amount to a significant cost burden to some patients given the context of high levels of poverty in Zambia. Findings suggest that the prevalence of informal payments is significantly associated with scarcity of healthcare resources at health facilities. Facilities appear to informally impose charges in response to inadequate staffing and general resource shortages in health facilities. Further, informal payments are more common in urban facilities. From a policy perspective, increasing general facility budgets and staffing would be required to reduce incentives for informal payments in the Zambian health system. Our study also raises a policy concern that informal payments can undermine public confidence in the government policy of free primary healthcare. The study suggests further research into the phenomenon of informal payments in healthcare in Africa.

Hardship financing of out-of-pocket payments in the context of free healthcare in Zambia.

Despite the removal of user fees on public primary healthcare in Zambia, prior studies suggest that out-of-pocket payments are still significant. However, we have little understanding of the extent to which out-of-pocket payments lead patients to hardship methods of financing out-of-pocket costs. This study analyses the prevalence and determinants of hardship financing arising from out-of-pocket payments in healthcare, using data from a nationally-representative household health expenditure survey conducted in 2014. We employ a sequential logistic regression model to examine the factors associated with the risk of hardship financing conditional on reporting an illness and an out-of-pocket expenditure. The results show that up to 11% of households who reported an illness had borrowed money, or sold items or asked a friend for help, or displaced other household consumption in order to pay for health care. The risk of hardship financing was higher among the poorest households, female headed-households and households who reside further from health facilities. Improvements in physical access and quality of public health services have the potential to reduce the incidence of hardship financing especially among the poorest.

Intracranial metastasis in fibrolamellar hepatocellular carcinoma.

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare liver malignancy in adolescents and young adults. Surgery is the mainstay of therapy for primary and metastatic disease. Most patients relapse, with development of both local and distant metastases. Brain metastases from solid tumors are rare in the pediatric and young adult population. Here, we document three patients with brain metastases from FLHCC, confirmed by histology and molecular characterization of the chimeric fusion DNAJB1-PRKACA, each necessitating neurosurgical intervention. These observations highlight the ability of FLHCC to metastasize to the brain and suggest the need for surveillance neuroimaging for patients with advanced-stage disease.
