Perceptions of factors influencing healthful food consumption behavior in the Lower Mississippi Delta: focus group findings

OBJECTIVE: To identify perceptions of Lower Mississippi Delta (LMD) residents regarding factors that influence a change in healthful food consumption behavior to assist in planning sustainable nutrition interventions in the LMD. DESIGN: Nine focus groups were conducted with LMD residents in 9 counties in Arkansas, Louisiana, and Mississippi. One focus group was held in each county on the topical area of behavioral change. SETTING: Nine counties in Arkansas, Louisiana, and Mississippi. PARTICIPANTS: The study population included 91 persons, 85 females and 6 males (18-60+ years of age), of whom 71 were African Americans, 17 were Caucasians, and 3 were Hispanics, who participated in the focus group discussions. ANALYSIS: Data analyses were completed by general and specific content coding. Data were reviewed for emerging themes for each topic. The Social Cognitive Theory served as the framework for understanding the determinants of a change in healthful food consumption behavior. RESULTS: The study showed considerable variability in perceptions that are influenced by both personal and external factors. These factors include health concerns, family influence, and need for and availability of nutrition information. Participants were interested in learning about healthful eating, food preparation skills, and portion control. CONCLUSIONS: Focus groups in the LMD identified many important themes relevant to the development of nutrition interventions in these communities. These data will be used to guide the community-based participatory interventions that will be developed and implemented in the LMD. The findings could be applicable to other researchers designing interventions for similar populations.     

The epidemiological and clinical picture of urolithiasis at the Kenyatta National Hospital

The findings of a 10-year retrospective study (January 1978 to December 1987) carried out at the General Surgical Units, Kenyatta National Hospital are presented. 82 patients with 89 episodes of stone disease were studied. An annual incidence of 8.9 was recorded. The sex ratio was 4.5:1 male:female. Pain, dysuria, frequency, retention, infection and haematuria are quite common. Most stones are in the bladder.     

Isolated diffusing capacity reduction is a common clinical presentation in deployed Iraq and Afghanistan veterans with deployment‐related environmental exposures

Following deployment to Iraq and Afghanistan (“post‐9/11”), a spectrum of respiratory conditions has been reported; however, there are few published reports of objective physiologic data or later experience of symptoms and function. To better understand the post‐deployment clinical presentation, we conducted a retrospective review of pulmonary function testing in 143 veterans referred to our tertiary care clinic for post‐deployment health concerns. More than 75% of our sample had normal lung volumes and spirometry on pulmonary function testing; however, an isolated reduction in lung diffusing capacity (DLCO) was observed in 30% of our sample of post‐9/11 veterans. An isolated reduction in DLCO is a rare pattern in primary‐care seeking dyspneic patients, but is commonly associated with underlying pulmonary disease. Post‐9/11 veterans with respiratory complaints and an isolated reduction in DLCO should undergo further evaluation.     

Exploring the associations between physical and sexual gender-based violence and HIV among women who use substances in South Africa: the role of agency and alcohol

ABSTRACT

Objective: South Africa has the highest prevalence of HIV among women, the highest prevalence of gender-based violence (GBV), and the highest rates of per capita alcohol consumption in the world. The nuanced associations between GBV, alcohol misuse, and HIV must be explored and protective factors identified. This study examines the associations between physical and sexual GBV and HIV infection and explores how alcohol misuse and sexual agency may mediate the GBV-HIV association.

Method: Participants were 361 Black African women (Mean age_?=_?28.39, SD?=?7.92) who reported using alcohol and/or drugs weekly in the past 3 months, engaging in condomless sex, and having a boyfriend. Women were recruited from disadvantaged communities in Pretoria, South Africa. Individuals who met the eligibility criteria and enrolled in the study consented and completed a computer-assisted personal interview assessing GBV, alcohol misuse, and sexual agency and underwent HIV testing (i.e., blood test).

Results: The indirect effect of physical assault on HIV status at enrollment through alcohol misuse was significant (log odds = 0.23, SE = 0.12, 95% CI [0.0151, 0.4998]).

Conclusions: HIV prevention efforts focusing on reducing alcohol misuse may be more effective, which might reduce the HIV burden among this group of vulnerable South African women.     

Outcomes of Implementing in the Real World the Women's Health CoOp Intervention in Cape Town,South Africa

Women in South Africa living with HIV who use alcohol may not adhere to ART, affecting the country’s 90-90-90 targets. The Women’s Health CoOp (WHC), a woman-focused HIV intervention, has shown efficacy in numerous trials with key populations of women in South Africa who use alcohol and drugs. In a hybrid implementation effectiveness study, the WHC was implemented in usual care clinics by healthcare providers in a modified stepped-wedge design. We present the outcomes of alcohol use and ART adherence with 480 women, with a 95% 6-month follow-up rate across 4 implementation cycles. Compared with the first cycle, women in the fourth cycle were significantly less likely (OR = 0.10 [95% CI 0.04, 0.24]) to report alcohol use disorder risk and were 4 times more likely (OR = 4.16 [95% CI 1.05, 16.51]) to report ART adherence at 6-month follow-up. Overall, acceptability and satisfaction were extremely high. The WHC intervention was successful in reaching key populations of women to reduce alcohol use and increase ART adherence, which is essential for South Africa to reach the 90-90-90 goals.

     

Acquisition of rectal colonization by vancomycin-resistant Enterococcus among intensive care unit patients treated with piperacillin-tazobactam versus those receiving cefepime-containing antibiotic regimens

In contrast to expanded-spectrum cephalosporins, beta-lactam-beta-lactamase inhibitor combinations such as piperacillin-tazobactam have rarely been associated with vancomycin-resistant Enterococcus (VRE) colonization and infection. In mice, piperacillin-tazobactam has sufficient antienterococcal activity to inhibit the establishment of colonization during treatment, but this effect has not been confirmed in human patients. We prospectively evaluated the acquisition of rectal colonization by VRE among intensive care unit patients receiving antibiotic regimens containing piperacillin-tazobactam versus those receiving cefepime, an expanded-spectrum cephalosporin with minimal antienterococcal activity. Rectal swabs were obtained weekly and were cultured for VRE. For 146 patients with a negative rectal swab for VRE prior to therapy, there was no significant difference in the frequency of VRE acquisition between patients receiving piperacillin-tazobactam- and cefepime-containing regimens (19/72 [26.4%] and 23/74 [31.1%], respectively; P = 0.28). Of the 19 patients who acquired VRE in association with piperacillin-tazobactam, 10 (53%) developed the new detection of VRE during therapy. Patients initiated on treatment with cefepime-containing regimens were significantly more likely than those initiated on treatment with piperacillin-tazobactam-containing regimens to have received antibiotic therapy in the prior 30 days (55/74 [74.3%] and 22/72 [30.6%], respectively; P < 0.001). These findings suggest that piperacillin-tazobactam- and cefepime-containing antibiotic regimens may be associated with the frequent acquisition of VRE in real-world intensive care unit settings. Although piperacillin-tazobactam inhibits the establishment of VRE colonization in mice when exposure occurs during treatment, our data suggest that this agent may not prevent the acquisition of VRE in patients.
