RESUMO

OBJECTIVES: To assess the cost-effectiveness, resource use implications, quality-adjusted life-years (QALYs) and cost per QALY of care pathways starting with either extracorporeal shockwave lithotripsy (SWL) or with ureteroscopic retrieval (ureteroscopy [URS]) for the management of ureteric stones. PATIENTS AND METHODS: Data on quality of life and resource use for 613 patients, collected prospectively in the Therapeutic Interventions for Stones of the Ureter (TISU) randomized controlled trial (ISRCTN 92289221), were used to assess the cost-effectiveness of two care pathways, SWL and URS. A health provider (UK National Health Service) perspective was adopted to estimate the costs of the interventions and subsequent resource use. Quality-of-life data were calculated using a generic instrument, the EuroQol EQ-5D-3L. Results are expressed as incremental cost-effectiveness ratios and cost-effectiveness acceptability curves. RESULTS: The mean QALY difference (SWL vs URS) was -0.021 (95% confidence interval [CI] -0.033 to -0.010) and the mean cost difference was -£809 (95% CI -£1061 to -£551). The QALY difference translated into approximately 10 more healthy days over the 6-month period for the patients on the URS care pathway. The probabaility that SWL is cost-effective is 79% at a society's willingness to pay (WTP) threshold for 1 QALY of £30,000 and 98% at a WTP threshold of £20,000. CONCLUSION: The SWL pathway results in lower QALYs than URS but costs less. The incremental cost per QALY is £39 118 cost saving per QALY lost, with a 79% probability that SWL would be considered cost-effective at a WTP threshold for 1 QALY of £30 000 and 98% at a WTP threshold of £20 000. Decision-makers need to determine if costs saved justify the loss in QALYs.

RESUMO

PURPOSE: To summarise the current knowledge regarding diagnostics, prognostication and follow-up in upper tract urothelial carcinoma (UTUC). METHODS: A scoping review combined with expert opinion was applied to provide an overview of the current research field. Based on the published literature and the experts' own experience and opinions, consensus was reached through presentations and discussions at the meeting Consultation on UTUC II in Stockholm 2022. RESULTS: The strongest prognostic factors in UTUC are tumour grade and stage. They are correlated, and grade is used for indirect staging. The diagnostic examinations should include multiphase computed tomography urography (CTU) with corticomedullary phase, and urethrocystoscopy with cytology. If there is no clear diagnosis for clinical decision-making, ureterorenoscopy (URS) with focal cytology and biopsies should be performed. Both WHO classification systems (1973/1999 and 2004/2016) should be used. Novel biomarker tests are not yet widespread nor recommended for the detection of UTUC. Long-term, regular follow-up, including URS in patients who have had organ-sparing treatment, is important to check for tumour recurrences, intravesical recurrences, metastases and progression of the tumour. CONCLUSION: Proper diagnostics with correct grading of UTUC are necessary for appropriate treatment decisions. The diagnostics should include CTU with corticomedullary phase, urine or bladder cytology, URS with focal barbotage cytology, and biopsies when needed for proper diagnosis and risk stratification. Regular, long-term follow-ups are fundamental, due to the high rate of recurrence and risk of progression.

RESUMO

BACKGROUND: Ghana introduced a mobile phone-based contribution payment system in its national health insurance scheme (NHIS) in December 2018 to improve the process of enrolment. We evaluated the effect of this digital health intervention on retention of coverage in the Scheme, one year after its implementation. METHODS: We used NHIS enrolment data for the period, 1 December 2018-31 December 2019. Descriptive statistics and propensity-score matching method were performed to examine a sample of 57,993 members' data. RESULTS: Proportion of members who renewed their membership in the NHIS via the mobile phone-based contribution payment system increased from 0% to 8.5% whilst those who did so through the office-based system only grew from 4.7% to 6.4% over the study period. The chance of renewing membership was higher by 17.4 percentage points for users of the mobile phone-based contribution payment system, compared to those who used the office-based contribution payment system. The effect was greater for the informal sector workers, males and the unmarried. CONCLUSIONS: The mobile phone-based health insurance renewal system is improving coverage in the NHIS particularly for members who hitherto were less likely to renew their membership. Policy makers need to devise an innovative way for new members and all member categories to enrol using this payment system to accelerate progress towards attainment of universal health coverage. Further study needs to be conducted using mixed-method design with inclusion of more variables.

RESUMO

BACKGROUND: The role of adjuvant chemotherapy (AC) in stage III rectal cancer (RC) has been argued based on evidence from its use in colon cancer. Previous trials have analysed disease-free and overall survivals as endpoints, rather than disease recurrence. This study compares the competing risks incidences of recurrence and cancer-specific death between patients who did and did not receive AC for stage III RC. METHODS: Consecutive patients who underwent a potentially curative resection for stage III RC (1995-2019) at Concord Hospital, Sydney, Australia, were studied. AC was considered following multidisciplinary discussion. Primary outcome measures were the competing risks incidences of disease recurrence and cancer-specific death. Associations between these outcomes and use of AC (and other variables) were tested by regression modelling. RESULTS: Some 338 patients (213 male, mean age 64.4 years [SD12.7]) were included. Of these, 208 received AC. The use of AC was associated with resection year (adjusted OR [aOR] 1.74, 95%CI 1.27-2.38); age ≥75 years (aOR0.04, 95%CI 0.02-0.12); peripheral vascular disease (aOR0.08, 95%CI 0.01-0.74); and postoperative abdomino-pelvic abscess (aOR0.23, 95%CI 0.07-0.81). One hundred fifty-seven patients (46.5%) were diagnosed with recurrence; death due to RC occurred in 119 (35.2%). After adjustment for the competing risk of non-cancer death, neither recurrence nor RC-specific death was associated with AC (HR0.97, 95%CI 0.70-1.33 and HR0.72, 95%CI 0.50-1.03, respectively). CONCLUSION: This study found no significant difference in either recurrence or cancer-specific death between patients who did and did not receive AC following curative resection for stage III RC.

RESUMO

INTRODUCTION: Hypertension is a growing burden in Uganda and other low- and middle-income countries. Appropriate diagnosis services are needed at primary care health facilities to identify, initiate treatment for, and manage hypertension. This study assessed service availability and readiness as well as facilitators and barriers in primary health care facilities for hypertension diagnosis services in Wakiso District, Uganda. METHODS: In July and August 2019, we conducted structured interviews at 77 randomly selected primary care health facilities in Wakiso District. We used an interviewer-administered health facility checklist modified from the World Health Organization's service availability and readiness assessment tool. We also conducted 13 key informant interviews with health workers and district-level managers. Readiness was measured by availability of functional diagnostic equipment, related supplies and tools, and health provider attributes. Service availability was measured by assessing hypertension diagnosis services. RESULTS: Most (86%; 66 of 77) health facilities offered hypertension diagnosis services and 84% (65 of 77) had digital blood pressure measuring devices; only 69% (53 of 77) had functional blood pressure measuring devices. Lower-level facilities lacked appropriate blood pressure cuffs for use across age groups: 92% (71 of 77) lacked pediatric cuffs and 52% (40 of 77) lacked alternative adult cuffs. Facilitators for diagnosing hypertension included partners that built health facility staff capacity and funds for purchasing hypertension diagnostic supplies; common barriers were nonfunctional equipment, delays in receiving training, and inadequate staffing. CONCLUSION: The results highlight the need for an adequate supply of devices, routine replacements or repairs, and frequent refresher training for health workers.

RESUMO

OBJECTIVES: To evaluate the use of pre-cryoablation biopsy for small renal masses (SRMs) and the effects of increasing uptake on histological results of treated SRMs. METHODS: From 2015 to 2019, patients with sporadic T1N0M0 SRMs undergoing percutaneous, laparoscopic, or open cryoablation from 14 European institutions within the European Registry for Renal Cryoablation (EuRECA) were included for the retrospective analysis. Univariate and multivariate logistic models were used to evaluate the trends, histological results, and the factors influencing use of pre-cryoablation biopsy. RESULTS: In total, 871 patients (median (IQR) age, 69 (14), 298 women) undergoing cryoablation were evaluated. The use of pre-cryoablation biopsy has significantly increased from 42% (65/156) in 2015 to 72% (88/122) in 2019 (p < 0.001). Patients treated for a benign histology are significantly more likely to have presented later in the trend, where pre-cryoablation biopsy is more prevalent (OR: 0.64, 95% CI 0.51-0.81, p < 0.001). Patients treated for undiagnosed histology are also significantly less likely to have presented in 2018 compared to 2016 (OR 0.31, 95% CI 0.10-0.97, p = 0.044). Patients aged 70+ are less likely to be biopsies pre-cryoablation (p < 0.05). R.E.N.A.L. nephrometry score of 10+ and a Charlson Comorbidity Index > 1 are factors associated with lower likelihood to not have received a pre-cryoablation biopsy (p < 0.05). CONCLUSION: An increased use of pre-cryoablation biopsy was observed and cryoablation patients treated with a benign histology are more likely to have presented in periods where pre-cryoablation biopsy is not as prevalent. Comparative studies are needed to draw definitive conclusions on the effect of pre-cryoablation biopsy on SRM treatments. KEY POINTS: • The use of biopsy pre-ablation session has increased significantly from 42% of all patients in 2015 to 74% in 2019. • Patients are less likely to be treated for a benign tumour if they presented later in the trend, where pre-cryoablation biopsy is more prevalent, compared to later in the trend (OR 0.64, 95% CI 0.51-0.81, p < 0.001). • Patients with comorbidities or a complex tumour (R.E.N.A.L. nephrometry score > 10) are less likely to not undergo biopsy as a separate session to cryoablation.

RESUMO

BACKGROUND: Understanding motivational determinants of physical activity (PA) is essential to guide the implementation of PA at individual and population level. Knowledge about the cross-cultural generalizability of these determinants is lacking and they have mostly been studied as separate factors. This study compares a motivational process model across samples from diverse populations with, or at risk of diabetes. METHODS: Measurement invariance of barrier identified regulation, barrier self-efficacy and social support was assessed in a rural Ugandan sample (n = 712) and disadvantaged samples with high proportions of immigrants in urban South Africa (n = 566) and Sweden (n = 147). These motivational determinants were then compared through multigroup structural equation modeling. RESULTS: The studied motivational constructs showed scalar invariance. Latent mean levels of perceived social support and barrier self-efficacy were lower in South Africa and Sweden. Structural models (for different PA outcomes) were not consistent across settings except for the association between perceived social support and identified regulation. Identified regulation was only associated with vigorous PA in Uganda and with moderate PA in South Africa. The association between social support and PA outcomes ranged from weak to not significant and the association between self-efficacy and PA was not significant. Self-reported PA was highest in Uganda and lowest in Sweden. Self-reported vigorous PA was significantly related to lower hemoglobin A1c levels, while moderate PA was not. CONCLUSIONS: Findings suggest that: 1) it is feasible to compare a motivational process model across diverse settings; 2) there is lower perceived social support and self-efficacy in the urban, migrant samples; 3) identified regulation is a more promising determinant of PA than self-efficacy or social support in these populations; 4) associations between motivational determinants and PA depend on the perceived type and/or intensity of PA; 5) perceived relatedness functions as a basic psychological need across diverse settings; and 6) people's perception of the PA they perform depends on their perceived level of intensity of PA which would have major implications for health promotion.

RESUMO

BACKGROUND: Urothelial carcinomas of the upper urinary tract (UTUCs) are rare, with poorer stage-for-stage prognosis than urothelial carcinomas of the urinary bladder. No international consensus exists on the benefit of adjuvant chemotherapy for patients with UTUCs after nephroureterectomy with curative intent. The POUT (Peri-Operative chemotherapy versus sUrveillance in upper Tract urothelial cancer) trial aimed to assess the efficacy of systemic platinum-based chemotherapy in patients with UTUCs. METHODS: We did a phase 3, open-label, randomised controlled trial at 71 hospitals in the UK. We recruited patients with UTUC after nephroureterectomy staged as either pT2-T4 pN0-N3 M0 or pTany N1-3 M0. We randomly allocated participants centrally (1:1) to either surveillance or four 21-day cycles of chemotherapy, using a minimisation algorithm with a random element. Chemotherapy was either cisplatin (70 mg/m2) or carboplatin (area under the curve [AUC]4·5/AUC5, for glomerular filtration rate <50 mL/min only) administered intravenously on day 1 and gemcitabine (1000 mg/m2) administered intravenously on days 1 and 8; chemotherapy was initiated within 90 days of surgery. Follow-up included standard cystoscopic, radiological, and clinical assessments. The primary endpoint was disease-free survival analysed by intention to treat with a Peto-Haybittle stopping rule for (in)efficacy. The trial is registered with ClinicalTrials.gov, NCT01993979. A preplanned interim analysis met the efficacy criterion for early closure after recruitment of 261 participants. FINDINGS: Between June 19, 2012, and Nov 8, 2017, we enrolled 261 participants from 57 of 71 open study sites. 132 patients were assigned chemotherapy and 129 surveillance. One participant allocated chemotherapy withdrew consent for data use after randomisation and was excluded from analyses. Adjuvant chemotherapy significantly improved disease-free survival (hazard ratio 0·45, 95% CI 0·30-0·68; p=0·0001) at a median follow-up of 30·3 months (IQR 18·0-47·5). 3-year event-free estimates were 71% (95% CI 61-78) and 46% (36-56) for chemotherapy and surveillance, respectively. 55 (44%) of 126 participants who started chemotherapy had acute grade 3 or worse treatment-emergent adverse events, which accorded with frequently reported events for the chemotherapy regimen. Five (4%) of 129 patients managed by surveillance had acute grade 3 or worse emergent adverse events. No treatment-related deaths were reported. INTERPRETATION: Gemcitabine-platinum combination chemotherapy initiated within 90 days after nephroureterectomy significantly improved disease-free survival in patients with locally advanced UTUC. Adjuvant platinum-based chemotherapy should be considered a new standard of care after nephroureterectomy for this patient population. FUNDING: Cancer Research UK.

RESUMO

NEW FINDINGS: What is the central question of this study? What ex vivo preparation of the rat's cavoatrial junction is efficient for characterising atrial mechanoreceptors? What is the main finding and its importance? Of four different ex vivo preparations, static pressure, flow, open and euthermic, the optimal preparation was the euthermic one and involved direct recording from the right cardiac vagal branch with a Langendorff style perfusion at 37°C. Type A receptors were most common, and appeared insensitive to stretch and sensitive to atrial contraction. Type B and intermediate receptors were not isolated at 20°C but were observed closer to 37°C. The findings may suggest that type A and B receptors utilise different molecular transduction mechanisms. ABSTRACT: Atrial volume receptors are a family of afferent neurons whose mechanically sensitive endings terminate in the atria, particularly at the cavoatrial junctions. These mechanosensors form the afferent limb of an atrial volume receptor reflex that regulates plasma volume. The prevailing functional classification of atrial receptors arose as a result of in vivo recordings in the cat and dog and were classified as type A, B or intermediate according to the timing of peak discharge during the cardiac cycle. In contrast, there have been far fewer studies of the common small laboratory mammals such as the rat. Using several ex vivo rat cavoatrial preparations, a total of 30 successful single cavoatrial mechanosensory recordings were obtained. These experiments show that the rat possesses type A, B and intermediate atrial mechanoreceptors as described for larger mammals. Recording these cavoatrial receptors proved challenging from the main vagus, but direct recording from the cardiac vagal branch greatly increased the yield of mechanically sensitive single units. In contrast to type A units, type B atrial mechanoreceptor activity was never observed at room temperature but required elevation of temperature to a more physiological range in order to be detected. The adequate stimulus for these receptors remains unclear; however, type A atrial receptors appear insensitive to direct atrial stretch when applied using a programmable positioner. The findings may suggest that type A and type B atrial receptors utilise different molecular transduction mechanisms.

RESUMO

Objective: Hypotension in the prehospital environment is common and linked to dose-dependent mortality. Bolus dose epinephrine (BDE) may reverse hypotension. We tested if BDE use to treat profound hypotension is associated with 24-hour survival. Methods: We performed a retrospective case-cohort study of critical care transport patients with systolic blood pressure (SBP) <70 mmHg from January 2011 to January 2017. To account for baseline differences between treated and untreated patients, we used nearest neighbor matching to estimate the average treatment effect of BDE on 24-hour survival. Included covariates were age, gender, shock type (cardiogenic, distributive, obstructive or hypovolemic), weight, type of service, vitals (heart rate, SBP and diastolic blood pressure, respiratory rate, oxygen saturation, end-tidal carbon dioxide, and Glasgow Coma Scale score) at the time of the first hypotensive episode, as well as pretreatment characteristics including cardiopulmonary resuscitation, defibrillation, transcutaneous pacing, needle thoracostomy, vasopressors, intubation, or arrhythmias. After statistical analysis, we assessed for residual bias by selecting random matched patient records and asking 2 blinded physicians to rate overall illness severity on a Likert scale. We compared perceived illness severity between cases and matched controls using a rank-sum test. Results: There were 6,992 patients transported with SBP <70 mmHg at least once and 4,374 meet inclusion criteria. Of the 1,620 patients transported after protocol implementation, 574 (35%) received BDE. Overall 24-hour survival, survival to discharge and 30-day survival were 80, 57, and 54%, respectively. Survival at 24 hours differed between the BDE group (66%) and controls (82%). These differences persisted at both discharge and 30 days. Administration of BDE was associated with increased post-treatment SBP. BDE treated patients were also more likely to receive cardiopulmonary resuscitation and vasopressors after treatment than untreated hypotensive patients, but there was no association with tachydysrhythmias requiring defibrillation. Conclusions: Bolus dose epinephrine increases blood pressure in the prehospital setting. Despite robust efforts to control for confounding, BDE remained associated with increased mortality in this observational cohort. This association may be due to unmeasured confounding and a randomized controlled trial is necessary to establish a causal relationship between bolus dose vasopressors and mortality.

RESUMO

BACKGROUND: The burden of type 2 diabetes in Sub-Saharan Africa is projected to double by 2040, partly attributable to rapidly changing diets. In this paper, we analysed how community members in rural Uganda understood the concept of a healthy or unhealthy diet, food preparation and serving practices to inform the process of facilitating knowledge and skill necessary for self-management and care for type 2 diabetes. This was a qualitative study involving 20 focus group discussions and eight in-depth interviews among those at risk, patients with type 2 diabetes and the general community members without diabetes mellitus. Data was coded and entered into Atlas ti version 7.5.12 and interpreted using thematic analysis. We identified three main themes, which revealed, the perceptions on food and diet concerning health; the social dimensions of food and influence on diet practices; and food as a gendered activity. Participants noted that eating and cooking practices resulted in unhealthy diets. Their practices were affected by beliefs, poverty and food insecurity. Women determined which foods to prepare, but men prepared only some of the foods such as delicacies like a rice dish "pilau." New commercial and processed foods were increasingly available and consumed even in rural areas. Participants linked signs and symptoms of illness to diet as they narrated changes from past to current food preparation behaviours. Their view of overweight and obesity was also gendered and linked to social status. Participants' perception of disease influenced by diet was similar among those with and without type 2 diabetes, and those at risk. People described what is a healthy diet was as recommended by the health workers, but stated that their practices differed greatly from their knowledge. There was high awareness about healthy and balanced diets, but food is entrenched within social and gendered paradigms, which are slowly changing. Social and gender dimensions of food will need to be addressed through interventions in communities to promote change on a society level.

RESUMO

BACKGROUND: Ghana introduced a National Health Insurance Scheme (NHIS) in 2003 applying fee-for-service method for paying NHIS-credentialed health care providers. The National Health Insurance Authority (NHIA) later introduced diagnosis-related-grouping (DRG) payment to contain cost without much success. The NHIA then introduced capitation payment, a decision that attracted complaints of falling enrolment and renewal rates from stakeholders. This study was done to provide evidence on this trend to guide policy debate on the issue. METHODS: We applied mixed method design to the study. We did a trend analysis of NHIS membership data in Ashanti, Volta and Central regions to assess growth rate; performed independent-sample t-test to compare sample means of the three regions and analysed data from individual in-depth interviews to determine any relationship between capitation payment and subscribers' renewal decision. RESULTS: Results of new enrolment data analysis showed differences in mean growth rates between Ashanti (M = 30.15, SE 3.03) and Volta (M = 40.72, SE 3.10), p = 0.041; r = 0. 15; and between Ashanti and Central (M = 47.38, SE6.49) p = 0.043; r = 0. 42. Analysis of membership renewal data, however, showed no significant differences in mean growth rates between Ashanti (M = 65.47, SE 6.67) and Volta (M = 69.29, SE 5.04), p = 0.660; r = 0.03; and between Ashanti and Central (M = 50.51, SE 9.49), p = 0.233. Analysis of both new enrolment and renewal data also showed no significant differences in mean growth rates between Ashanti (M = - 13.76, SE 17.68) and Volta (M = 5.48, SE 5.50), p = 0.329; and between Ashanti and Central (M = - 6.47, SE 12.68), p = 0.746. However, capitation payment had some effect in Ashanti compared with Volta (r = 0. 12) and Central (r = 0. 14); but could not be sustained beyond 2012. Responses from the in-depth interviews did not also show that capitation payment is a key factor in subscribers' renewal decision. CONCLUSION: Capitation payment had a small but unsustainable effect on membership growth rate in the Ashanti region. Factors other than capitation payment may have played a more significant role in subscribers' enrolment and renewal decisions in the Ashanti region of Ghana.

RESUMO

BACKGROUND: Ghana introduced capitation payment method in 2012 but was faced with resistance for its perceived poor quality of care. This paper assesses National Health Insurance Scheme subscribers and care providers' perception of quality of care under the capitation payment method. METHODS: This is a cross-sectional survey of subscribers and care providers perception of quality of care in three administrative regions of Ghana using a 5-point Likert scale for the assessment based on a set of quality of care measures. We performed descriptive analysis to determine average perception of quality of care scores for each of the measures used. Bivariate and multivariate analyses were also performed to examine relationships between respondent's characteristics and their perception of quality of care. RESULTS: In general, subscribers expressed positive perception about the quality of care though subscribers in Ashanti were less positive compared to those in the Central region. A chi-square analysis, however, showed significant differences in subscribers' perception of quality of care by occupation (p = 0.002), region (p = 0.007) length of NHIS membership (p = 0.006), and age (p = 0.014). Multivariate logistic regression analysis also showed that different factors, other than region of residence, were significantly associated with perceived good quality of care. Analysis of health care providers' responses also showed significant differences in their perception of quality of care by region (p = 0.001). Multivariate logistic model showed that health care providers in the Volta region (OR = 0.14, 95% CI: 0.03-0.58) were significantly less likely to perceive quality of care as good compared to those in the Ashanti region. CONCLUSION: Subscribers and care providers across the three regions have relatively good perception of the quality of health care in general though subscribers in Ashanti were less positive than those in the Central region. It is, therefore, plausible that capitation payment may have influenced the relatively low perception of quality of care in the Ashanti region.

RESUMO

BACKGROUND: A robust medical claims review system is crucial for addressing fraud and abuse and ensuring financial viability of health insurance organisations. This paper assesses claims adjustment rate of the paper- and electronic-based claims reviews of the National Health Insurance Scheme (NHIS) in Ghana. METHODS: The study was a cross-sectional comparative assessment of paper- and electronic-based claims reviews of the NHIS. Medical claims of subscribers for the year, 2014 were requested from the claims directorate and analysed. Proportions of claims adjusted by the paper- and electronic-based claims reviews were determined for each type of healthcare facility. Bivariate analyses were also conducted to test for differences in claims adjustments between healthcare facility types, and between the two claims reviews. RESULTS: The electronic-based review made overall adjustment of 17.0% from GHS10.09 million (USD2.64 m) claims cost whilst the paper-based review adjusted 4.9% from a total of GHS57.50 million (USD15.09 m) claims cost received, and the difference was significant (p < 0.001). However, there were no significant differences in claims cost adjustment rate between healthcare facility types by the electronic-based (p = 0.0656) and by the paper-based reviews (p = 0.6484). CONCLUSIONS: The electronic-based review adjusted significantly higher claims cost than the paper-based claims review. Scaling up the electronic-based review to cover claims from all accredited care providers could reduce spurious claims cost to the scheme and ensure long term financial sustainability.

RESUMO

BACKGROUND: Globally, Médecins Sans Frontières (MSF) treats more than 300,000 severely malnourished children annually. Malnutrition is not only caused by lack of food but also by illnesses and by poor infant and child feeding practices. Breaking the vicious cycle of illness and malnutrition by providing ill children with nutritional supplementation is a potentially powerful strategy for preventing malnutrition that has not been adequately investigated. Therefore, MSF investigated whether incidence of malnutrition among ill children <5 y old could be reduced by providing a fortified food product or micronutrients during their 2-wk convalescence period. Two trials, one in Nigeria and one in Uganda, were conducted; here, we report on the trial that took place in Kaabong, a poor agropastoral region of Karamoja, in east Uganda. While the region of Karamoja shows an acute malnutrition rate between 8.4% and 11.5% of which 2% to 3% severe malnutrition, more than half (58%) of the population in the district of Kaabong is considered food insecure. METHODS AND FINDINGS: We investigated the effect of two types of nutritional supplementation on the incidence of malnutrition in ill children presenting at outpatient clinics during March 2011 to April 2012 in Kaabong, Karamoja region, Uganda, a resource-poor region where malnutrition is a chronic problem for its seminomadic population. A three-armed, partially-blinded, randomised controlled trial was conducted in children diagnosed with malaria, diarrhoea, or lower respiratory tract infection. Non-malnourished children aged 6 to 59 mo were randomised to one of three arms: one sachet/d of ready-to-use therapeutic food (RUTF), two sachets/d of micronutrient powder (MNP), or no supplement (control) for 14 d for each illness over 6 mo. The primary outcome was the incidence of first negative nutritional outcome (NNO) during the 6 mo follow-up. NNO was a study-specific measure used to indicate progression to moderate or severe acute malnutrition; it was defined as weight-for-height z-score <-2, mid-upper arm circumference (MUAC) <115 mm, or oedema, whichever came first. Of the 2,202 randomised participants, 51.2% were girls, and the mean age was 25.2 (±13.8) mo; 148 (6.7%) participants were lost to follow-up, 9 (0.4%) died, and 14 (0.6%) were admitted to hospital. The incidence rates of NNO (first event/year) for the RUTF, MNP, and control groups were 0.143 (95% confidence interval [CI], 0.107-0.191), 0.185 (0.141-0.239), and 0.213 (0.167-0.272), respectively. The incidence rate ratio was 0.67 (95% CI, 0.46-0.98; p = 0.037) for RUTF versus control; a reduction of 33.3%. The incidence rate ratio was 0.86 (0.61-1.23; p = 0.413) for MNP versus control and 0.77 for RUTF versus MNP (95% CI 0.52-1.15; p = 0.200). The average numbers of study illnesses for the RUTF, MNP, and control groups were 2.3 (95% CI, 2.2-2.4), 2.1 (2.0-2.3), and 2.3 (2.2-2.5). The proportions of children who died in the RUTF, MNP, and control groups were 0%, 0.8%, and 0.4%. The findings apply to ill but not malnourished children and cannot be generalised to a general population including children who are not necessarily ill or who are already malnourished. CONCLUSIONS: A 2-wk nutrition supplementation programme with RUTF as part of routine primary medical care to non-malnourished children with malaria, LRTI, or diarrhoea proved effective in preventing malnutrition in eastern Uganda. The low incidence of malnutrition in this population may warrant a more targeted intervention to improve cost effectiveness. TRIAL REGISTRATION: clinicaltrials.gov NCT01497236.

RESUMO

BACKGROUND: Ghana introduced capitation payment for primary care in 2012 with the view to containing escalating claims expenditure. This shift in provider payment method raised issues about its potential impact on patient-provider trust relationship and insured-patients' trust in the Ghana National Health Insurance Scheme. This paper presents findings of a study that explored insured-patients' perception about, and attitude towards capitation payment in Ghana; and determined whether capitation payment affect insured-patients' trust in their preferred primary care provider and the National Health Insurance Scheme in general. METHODS: We adopted a survey design for the study. We administered closed-ended questionnaires to collect data from insurance card-bearing members aged 18 years and above. We performed both descriptive statistics to determine proportions of observations relating to the variables of interest and chi-square test statistics to determine differences within gender and setting. RESULTS: Sixty-nine per cent (69 %) out of 344 of respondents selected hospital level of care as their primary care provider. The two most important motivations for the choice of a provider were proximity in terms of geographical access (40 %) and perceived quality of care (38 %). Eighty-eight per cent (88 %) rated their trust in their provider as (very) high. Eighty-two per cent (82 %) actively selected their providers. Eighty-eight per cent (88 %) had no intention to switch provider. A majority (91 %) would renew their membership when it expires. Female respondents (91 %; n = 281) were more likely to renew their membership than males (87 %; n = 63). Notwithstanding capitation payment experience, 81 % of respondents would recommend to their peers to enrol with the NHIS with rural dwellers (87 %; n = 156) being more likely to do so than urban dwellers (76 %; n = 188). Almost all respondents (92 %) rated the NHIS as (very) good. CONCLUSION: Health Insurance subscribers in Ghana have high trust in their primary care provider giving them quality care under capitation payment despite their negative attitude towards capitation payment. They are guided by proximity and quality of care considerations in their choice of provider. The NHIA would, however, have to address itself to the negative perceptions about the capitation payment policy.

RESUMO

The title compound, C14H13ClN2O2S, crystallized in the enanti-omorphic defining hexa-gonal space group P61 [Flack parameter = -0.02 (7)]. The partially hydrated form of the same compound, crystallizing in the triclinic space group P-1, has been reported previously [Kia et al. (2009b). Acta Cryst. E65, o1119], as has the crystal structure of the bromo derivative, also crystallizing in the space group P-1 [Kia et al. (2009a). Acta Cryst. E65, o821]. The title mol-ecule is non-planar with the planes of the benzene rings being inclined to one another by 76.62 (13)°, and has an E conformation about the C=N bond. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds forming 61 helical chains running along [001]. The chains are linked via C-H⋯O hydrogen bonds, C-H⋯π inter-actions and short Cl⋯O [3.015 (3) Å] inter-actions, forming a three-dimensional structure.

RESUMO

BACKGROUND: The Community-based Health Planning and Services (CHPS) initiative plays a key role in delivering maternal and child health nutrition services in Ghana. This study explored bottle necks hindering the delivery of maternal and child nutrition services at CHPS zones and searched for strategies to address them from the perspective of community health officers in rural Northern Ghana. METHODS: An exploratory qualitative cross-sectional study design using key informant interviews involving the municipal nutrition officer and Community Health Officers (CHOs) from eleven CHPS zones was carried out in April 2019. Manual data analysis was done using the framework analysis approach in qualitative data analysis for applied policy research. RESULTS: This study identified challenges of maternal and child nutrition services in the Jirapa municipality to be municipal health directorate and CHPS zone based in nature. Municipal health directorate based challenges were inadequate logistics/medicines; lack of staff training; lack of supervision/monitoring; and inadequate financial support/motivation/incentives. CHPS zone based challenges were lack of planning activities by staff; inadequate home visits; lack of commitment by staff; and lack of community meetings/engagements. Proposed strategies to address municipal health directorate based challenges included adequate provision of logistics/medicines; frequent training of staff in maternal and child nutrition related issues; frequent supervision/monitoring activities from the municipal health directorate; and providing financial support/motivation/incentives at the CHPS zones. Proposed strategies to address CHPS zone based challenges were planning of activities; improved home visits; increased commitment towards delivering maternal and child nutrition services; and frequent community meetings/engagements. CONCLUSION: In order to improve maternal and child nutrition services at CHPS zones, there is the need to address certain systemic challenges at both the municipal or district health directorate and CHPS zones levels of the primary health care system. It is recommended that, the Municipal Health Directorate; the Municipal Health Management Team; the Municipal Assembly and all relevant stakeholders involved in improving maternal and child nutrition services at the community level, actively engage CHOs to help address the systemic challenges.

RESUMO

The aim of this study was to screen the chemical components of Solanum elaeagnifolium leaves and assess their therapeutic attributes with regard to their antioxidant, antibacterial, and antidiabetic activities. The antidiabetic effects were explored to determine the α-amylase and α-glucosidase inhibitory potential of the leaf extract. To identify the active antidiabetic drugs from the extracts, the GC-MS-screened molecules were docked with diabetes-related proteins using the glide module in the Schrodinger Tool. In addition, molecular dynamics (MD) simulations were performed for 100 ns to evaluate the binding stability of the docked complex using the Desmond module. The ethyl acetate had a significant total phenolic content (TPC), with a value of 79.04 ± 0.98 mg/g GAE. The ethanol extract was tested for its minimum inhibitory concentration (MIC) for its bacteriostatic properties. It suppressed the growth of B. subtilis, E. coli, P. vulgaris, R. equi and S. epidermis at a dosage of 118.75 µg/mL. Moreover, the IC50 values of the ethanol extract were determined to be 17.78 ± 2.38 in the α-amylase and and 27.90 ± 5.02 µg/mL in α-glucosidase. The in-silico investigation revealed that cyclolaudenol achieved docking scores of -7.94 kcal/mol for α-amylase. Likewise, the α-tocopherol achieved the docking scores of -7.41 kcal/mol for glycogen phosphorylase B and -7.21 kcal/mol for phosphorylase kinase. In the MD simulations, the cyclolaudenol and α-tocopherol complexes exhibited consistently stable affinities with diabetic proteins throughout the trajectory. Based on these findings, we conclude that this plant could be a good source for the development of novel antioxidant, antibacterial, and antidiabetic agents.Communicated by Ramaswamy H. Sarma.
