Background As of September 2014, Kenya implemented the WHO recommended Option B+ guidelines in which all newly diagnosed HIV-infected pregnant women are immediately eligible for triple antiretroviral therapy (ART) for life regardless of CD4 count. In addition, Kenya previously established the Kenya Mentor Mother Program (KMMP) in 2012 to improve peer education and psychosocial support services within the national prevention of mother-to-child transmission (PMTCT) program. The primary objectives of the study described in the current protocol are: (1) to evaluate implementation of these new guidelines (Option B+ with Mentor Mothers) as part of routine service delivery; and (2) to evaluate potential benefits of a package of services within the KMMP (called EMMA) to improve PMTCT service delivery. Methods We will conduct a cluster randomized controlled trial in western Kenya. We will allocate 12 clinics providing PMTCT services including ART to two study arms using pair matching: the standard of care (SOC) arm, which includes the KMMP as implemented by the clinics; and the intervention arm, which is the SOC (including KMMP) with the EMMA package of services (a targeted exit interview, visit reminders, and targeted follow-up). At the intervention clinics, the EMMA package of services is implemented as part of routine service delivery. A total of 360 (180 in each arm) pregnant women will be enrolled in the study at or near their first visit for antenatal care for prospective records review through 72 weeks post-partum. The primary and secondary outcomes are uninterrupted supplies of ART medications throughout the PMTCT cascade of care as well as infants completing HIV testing on schedule. Discussion The EMMA package of services provides specific structure to the use of Mentor Mothers within PMTCT programs. This strategy was developed in collaboration with local health facility and PMTCT program staff based on their experience providing PMTCT services within the integrated ART-MCH facilities. If successful, this approach has the potential to improve dramatically PMTCT service delivery with minor additional costs beyond the basic mother–mentor program and support global goals to eliminate mother-to-child transmission.

Background In the typical prevention of mother to child transmission (PMTCT) of HIV cascade of care discussion or analysis, the period of analysis begins at the first visit for antenatal care (ANC) for that pregnancy. This starting point is problematic for two reasons: (1) a large number of HIV-infected women are already on life-long antiretroviral therapy (ART) when presenting for ANC; and (2) women present to ANC at different gestational ages. The PMTCT ART Coverage Tool (PMTCT-ACT), which estimates the proportion of days covered (PDC) with ART, was developed to address each of these problems. Methods PDC is a preferred method to measure adherence to chronic medications, such as ART. For evaluating the PMTCT cascade of care, as indicated by PDC with ART over various time periods, a “starting point” based on a specific day before delivery must be defined that applies to all women (treatment experienced or naïve at the first ANC visit at any gestational age). Using the example of 168 days prior to delivery (24 weeks), PMTCT-ACT measures PDC with ART during that period. PMTCT-ACT is provided as a STATA do-file. Using an example dataset for two women (ID1 is treatment experienced; ID2 is treatment naïve), the details of each major portion of the tool (Parts 1–5) are presented. PMTCT-ACT along with the intermediate datasets created during the analysis are provided as supplemental files. Conclusions Evaluating the PMTCT cascade of care requires a standard definition of the follow-up period during pregnancy that applies to all HIV-infected pregnant women and a standard measure of adherence. PMTCT-ACT is a new tool that fits this purpose. PMTCT-ACT can also be easily adjusted to evaluate other ante- and post-natal periods (e.g., final 4 weeks, final 8 weeks, complete pregnancy period, initial 24 weeks postpartum, time periods consistent with infant HIV testing guidelines).

The healthcare needs of refugees and people seeking asylum are often broad and complex, with a higher burden of communicable diseases. There are limited data describing migrants’ experiences of accessing healthcare in Ireland. This cross-sectional study describes the experiences of migrants accessing healthcare services through an Irish Infectious Diseases clinic. Individuals attending the infectious diseases services in our hospital who had migrated to Ireland were included. Data were collected via a questionnaire, focusing on factors that may limit access to care, including communication, accessibility, cost, and stigmatisation. Seventy-six patients participated in this study. N = 20 (26%) of patients reported a commuting time of more than two hours to attend our clinic. N = 11 (15%) had experienced being unable to access healthcare in Ireland due to cost. Trust in healthcare providers was high (88%), and patient-reported satisfaction with communication was high (>90%). Persons living in direct provision services were more likely to report issues around privacy and less likely to have registered with a general practitioner. Accessibility and privacy were among the biggest challenges faced by migrants attending infectious diseases services at our centre, while communication and trust in healthcare providers were identified as areas of strength. Considering the burden of infectious diseases in migrant populations, and the challenges that certain migrant populations face in accessing healthcare, it is important to identify potential barriers to accessing care in order to ensure equitable, effective care. This study seeks to identify and describe the challenges that migrants face when accessing care through an Irish infectious diseases clinic. The results can help inform service provision and allocation of resources at a local level, while also identifying an area for further research regarding the barriers to accessing care faced by migrant communities in Ireland.

The current focus on staffing ratios as a means to assure appropriate care for patients ignores the very real differences among patients in their needs for nursing care. Implementing a system that identifies these needs provides a more accurate indication of staffing requirements. In addition, storing the raw data from the system at their most basic level provides opportunities for more extensive analyses and informed, data-driven decision-making related to resource allocation, performance improvement, and productivity enhancement.

From 2004 to 2014, the US President's Emergency Plan for AIDS Relief (PEPFAR) invested more than $248 000 000 in the prevention of mother-to-child transmission (PMTCT) of HIV in Kenya. Concurrently, child mortality in Kenya decreased by half. To identify the extent to which the decrease in child mortality in Kenya is associated with PEPFAR funding for PMTCT of HIV. This population-based survey study conducted in Kenya estimated the association between annual per capita PEPFAR funding for PMTCT (annual PCF) and cumulative per capita PEPFAR funding for PMTCT (cumulative PCF), extracted using 2004-2014 country operational reports as well as individual-level health outcomes, extracted from the 2003, 2008-2009, and 2014 Kenya Demographic and Health Surveys and the 2007 and 2012 Kenya AIDS Indicator Surveys. The study included children of female respondents to the 2003, 2008-2009, and 2014 Kenya Demographic and Health Surveys who were born 1 to 60 months (for neonatal mortality) or 12 to 60 months (for infant mortality) before the survey, as well as female respondents who had recently given birth and reported on HIV testing during antenatal care (ANC) during the 2007-2014 surveys. Results were adjusted for year, province, and survey respondent characteristics. Statistical analysis was performed from July 8, 2016, to December 10, 2018. Neonatal mortality was defined as death within the first month of life and infant mortality was defined as death within the first year of life. HIV testing during ANC was defined as receiving counseling on PMTCT, undergoing an HIV test, and receiving test results during ANC. The analysis included 33 181 neonates (16 870 boys), 26 876 infants (13 679 boys), and 20 775 mothers (mean [SD] age, 28.0 [6.7] years). PEPFAR funding was not associated with neonatal mortality. A $0.33 increase in annual PCF, corresponding to the difference between the 75th and 25th (interquartile range) percentiles of funding, was significantly associated with a 16% (95% CI, 4%-27%) reduction in infant mortality after a 1-year lag. A 14% to 16% reduction persisted after 2- and 3-year lags, and comparable reductions were observed for unlagged and 1-year lagged cumulative PCF. An increase of 1 interquartile range in cumulative PCF was associated with a 7% (95% CI, 3%-11%) increase in HIV testing during ANC, which intensified with subsequent lags. Between 2004 and 2014, sustained funding levels of $0.33 annual PCF could have averted 118 039 to 273 924 infant deaths. Evidence from publicly available data suggests that PEPFAR's PMTCT funding was associated with a reduction in infant mortality and an increase in HIV testing during ANC in Kenya. The full outcome of funding may not be realized until several years after allocation.

Large electrostatic potential variations (e(DELTA)(phi)/T(,e) > 1) in the form of sheaths and double layers (both stationary and moving) are studied in laboratory plasmas. Filament discharge plasmas are generated in a multidipole soup pot and a triple-plasma device where the electron density n(,e) is varied from 1 to 500 x 10('7) cm('-3) and the electron temperature T(,e) (TURN) 1 to 3 eV in argon and helium plasmas. Emitting, collecting and floating Langmuir probes are used to study the phenomena associated with large potential variations. Measurements on plasma-wall sheaths (e(DELTA)(phi)/T(,e) (TURN) 20) show general agreement with the theory by Bohm (1949) and Self (1963). The axial potential structure from a biased disc probe (-20 V) in a vacuum is measured with an emissive probe. The potential measured agrees with the potential predicted to within a factor of two. An investigation of the question of \"secondary\" electron emission in a sheath shows that they do not thermalize in the sheath. Emissive probe measurements of positive and negative probe sheaths are shown. Positive probe sheaths are found to have a corresponding negative well ((phi)(,well) (TURN) T(,e)/e). Double layers with e(DELTA)(phi)/T(,e) > 10, having sheath-like properties, are plotted in one and two dimensions. Moving double layers and well formations occur when a large plasma creation is produced in the region of a double layer. Moving double layers propagate at speeds up to 3.5 times the ion-acoustic speed.

Background: The Accreditation Council for Education in Nutrition and Dietetics requires that undergraduate dietetics courses utilize a variety of educational approaches to facilitate learning. The aim of this pilot study was to evaluate undergraduate nutrition students' perceptions of 16 classroom-based learning activities before and after taking an upper-level nutrition course. Methods: A survey was completed by students before and after taking an upper-level nutrition course, Methods in Nutrition Education, at a single university in the southwest region of the United States in fall 2016 and 2017. The survey included demographic questions and assessed students' perceptions of the helpfulness of 16 traditional and active classroom-based activities to learning. Perceptions were measured via Likert scale (1 = strongly disagree to 5 = strongly agree) at baseline and postcourse. Wilcoxon signed rank tests assessed changes in students' perceptions of learning activities from baseline to postcourse (significance = P < 0.05). Results: Ninety-seven completed baseline surveys; 67 (69%) completed postcourse surveys. Observing professionals (median = 5), interviewing professionals (median = 5), and critical thinking (median = 4) were perceived as most helpful to learning postcourse. Students agreed critical thinking, integrating material from other courses, interviewing professionals, case studies, writing short reports and summaries, and group projects and activities were significantly more helpful postcourse compared to baseline (P < 0.05). Discussion: Undergraduate nutrition students perceive a variety of classroom-based activities are helpful to learning including traditional (textbook readings, lectures) and active learning strategies (observation, practice). Instructors may consider implementing a variety of traditional and active learning strategies in upper-level nutrition and health-related courses to facilitate learning.

In this comparison of CT colonography and optical colonoscopy in 2600 asymptomatic study participants 50 years of age or older at 15 centers, 90% of large colorectal adenomas and adenocarcinomas detected by optical colonoscopy were also detected on CT colonography, and 10% were missed by CT colonography. In this comparison of CT colonography and optical colonoscopy, 90% of large colorectal adenomas and adenocarcinomas detected by optical colonoscopy were also detected on CT colonography. Colorectal cancer is the third most common cancer and the second leading cause of death from cancer in the United States, with an estimated 154,000 new cases and 52,000 deaths in 2007. 1 There is an enormous opportunity to save lives with broadly applied, widely accepted early-detection programs, since the natural history of colorectal cancer permits the recognition and curative treatment of both precursor adenomas and localized cancers. According to data from multiple sources, mortality from colorectal cancer is reduced with regular screening. 1 – 3 Despite its effectiveness, colorectal-cancer screening remains underused for many reasons, including drawbacks in terms of the performance, . . .

BackgroundDesmoplastic small round cell tumor (DSRCT) is a rare sarcoma that primarily affects adolescents and young adults. Patients can present with many peritoneal implants. We conducted a phase 2 clinical trial utilizing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) with cisplatin for DSRCT and pediatric-type abdominal sarcomas.Patients and MethodsA prospective cohort study was performed on 20 patients, who underwent CRS-HIPEC procedures, with cisplatin from 2012 to 2013. All patients were enrolled in the phase 2 clinical trial. Patients with extraabdominal disease and in whom complete cytoreduction (CCR0–1) could not be achieved were excluded. All outcomes were recorded.ResultsFourteen patients had DSRCT, while five patients had other sarcomas. One patient had repeat HIPEC. Patients with DSRCT had significantly longer median overall survival after surgery than patients with other tumors (44.3 vs. 12.5 months, p = 0.0013). The 3-year overall survival from time of diagnosis for DSRCT patients was 79 %. Estimated median recurrence-free survival (RFS) was 14.0 months. However, RFS for patients with DSRCT was significantly longer than for non-DSRCT patients (14.9 vs. 4.5 months, p = 0.0012). Among DSRCT patients, those without hepatic or portal metastases had longer median RFS than those with tumors at these sites (37.9 vs. 14.3 months, p = 0.02). In 100 % of patients without hepatic or portal metastasis, there was no peritoneal disease recurrence after CRS-HIPEC.ConclusionsComplete CRS-HIPEC with cisplatin is effective in select DSRCT patients. DSRCT patients with hepatic or portal metastasis have poorer outcomes.
