IMPORTANCE The effects of intensive care unit (ICU) visiting hours remain uncertain. OBJECTIVE To determine whether a flexible family visitation policy in the ICU reduces the incidence of delirium. DESIGN, SETTING AND PARTICIPANTS Cluster-crossover randomized clinical trial involving patients, family members, and clinicians from 36 adult ICUs with restricted visiting hours (<4.5 hours per day) in Brazil. Participants were recruited from April 2017 to June 2018, with follow-up until July 2018. INTERVENTIONS Flexible visitation (up to 12 hours per day) supported by family education (n = 837 patients, 652 family members, and 435 clinicians) or usual restricted visitation (median, 1.5 hours per day; n = 848 patients, 643 family members, and 391 clinicians). Nineteen ICUs started with flexible visitation, and 17 started with restricted visitation. MAIN OUTCOMES AND MEASURES Primary outcome was incidence of delirium during ICU stay, assessed using the CAM-ICU. Secondary outcomes included ICU-acquired infections for patients; symptoms of anxiety and depression assessed using the HADS (range, 0 [best] to 21 [worst]) for family members; and burnout for ICU staff (Maslach Burnout Inventory). RESULTS Among 1685 patients, 1295 family members, and 826 clinicians enrolled, 1685 patients (100%) (mean age, 58.5 years; 47.2% women), 1060 family members (81.8%) (mean age, 45.2 years; 70.3% women), and 737 clinicians (89.2%) (mean age, 35.5 years; 72.9% women) completed the trial. The mean daily duration of visits was significantly higher with flexible visitation (4.8 vs 1.4 hours; adjusted difference, 3.4 hours [95% CI, 2.8 to 3.9]; P < .001). The incidence of delirium during ICU stay was not significantly different between flexible and restricted visitation (18.9% vs 20.1%; adjusted difference, −1.7% [95% CI, −6.1% to 2.7%]; P = .44). Among 9 prespecified secondary outcomes, 6 did not differ significantly between flexible and restricted visitation, including ICU-acquired infections (3.7% vs 4.5%; adjusted difference, −0.8% [95% CI, −2.1% to 1.0%]; P = .38) and staff burnout (22.0% vs 24.8%; adjusted difference, −3.8% [95% CI, −4.8% to 12.5%]; P = .36). For family members, median anxiety (6.0 vs 7.0; adjusted difference, −1.6 [95% CI, −2.3 to −0.9]; P < .001) and depression scores (4.0 vs 5.0; adjusted difference, −1.2 [95% CI, −2.0 to −0.4]; P = .003) were significantly better with flexible visitation. CONCLUSIONS AND RELEVANCE Among patients in the ICU, a flexible family visitation policy, vs standard restricted visiting hours, did not significantly reduce the incidence of delirium.

HIV self-test kits may have the potential to increase testing rates around the globe, and thereby lead to reductions in HIV-related incidence and mortality. However, the effectiveness of these self-test kits and the issues surrounding self-testing have been greatly debated in recent years. We conducted a literature review on the acceptability, feasibility, and effectiveness of HIV self-testing (HST) around the world. Of the 28 articles abstracted, several themes of HST were explored, including behavioral risk compensation, presence of counseling, uses of HST, ability to perform the self-test, sensitivity and specificity, concordance with confirmatory testing, perceptions surrounding HST, instruction and supervision, and cost. Overall, this literature review found that this diverse group of participants generally performed HST correctly with a few exceptions, were accepting of the test if available at a relatively low cost, and preferred the oral-based HST over the blood-based test.

This intervention reduced infection rates by maintaining low-risk behaviors and changing high-risk behaviors. We elucidated the complex relationship between behavior and infection by incorporating context into variable conceptualization and considering several behaviors simultaneously.

Background Sexual problems are prevalently experienced by women with multiple sclerosis (MS) and have investigated in several studies. The nature of sexual changes in MS is best defined as primary, secondary, and tertiary. Objectives The aim of this study was to investigate three levels of sexual problems (SP) in female patients with MS and to examine their relationship with various clinical and demographic variables. Methods 132 women with MS completed two questionnaires; demographic and clinical history, and Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19). Fatigue was evaluated by Fatigue (energy) sub-scale of Multiple Sclerosis Quality of Life-54 (MSQOL-54) questionnaire. General physical ability and frequency of sexual intercourse were also evaluated. Results 115 patients (87.1%) reported primary SP. The most frequent symptoms of primary, secondary and tertiary sexual problems were delayed orgasm, spasticity and concern about partner’s sexual satisfaction, respectively. The MSISQ-19 total score was correlated with age(p=0.002), disease duration(p=0.010), marriage duration(p=0.001), fatigue(p<0.001), number of children(p=0.006), physical ability(p<0.001), education(p=0.006), economic status(p=0.002), number of times having sexual intercourse(p=0.007) and number of times approached by spouse for intercourse(p=0.012) in the last 30 days. Conclusions Sexual problems were prevalent among our participants. Appropriate management of SP depends on understanding the disturbed level.

Background: HIV self-testing (HIVST) can improve HIV-testing rates in ‘hard-to-reach’ populations, including men. We explored HIVST perceptions, delivery strategies, and post-test experiences among pregnant women and their male partners in Central Uganda. Methods: This was a qualitative study implemented as part of a pilot, cluster-randomized oral HIVST intervention trial among 1,514 pregnant women attending antenatal care services at three health facilities in Central Uganda. The qualitative component of the study was conducted between February and March 2017. We conducted 32 in-depth interviews to document women and men’s perceptions about HIVST, strategies used by women in delivering the kits to their male partners, male partners’ reactions to receiving kits from their female partners, and positive and negative social outcomes post-test. All interviews were audio-recorded, transcribed verbatim, and analyzed manually following a thematic framework approach. Results: Women were initially anxious about their male partners’ reaction if they brought HIVST kits home, but the majority eventually managed to deliver the kits to them successfully. Women who had some level of apprehension used a variety of strategies to deliver the kits including placing the kits in locations that would arouse male partners’ inquisitiveness or waited for ‘opportune’ moments when their husbands were likely to be more receptive. A few (three) women lied about the purpose of the test kit (testing for syphilis and other illnesses) while one woman stealthily took a mucosal swab from the husband. Most men initially doubted the ability of oral HIVST kits to test for HIV, but this did not stop them from using them. Both men and women perceived HIVST as an opportunity to learn about each other’s HIV status. No serious adverse events were reported post-test. Conclusion: Our findings lend further credence to previous findings regarding the feasibility of female-delivered HIVST to improve male partner HIV testing in sub-Saharan Africa. However, support for women in challenging relationships is required to minimize potential for deception and coercion.

Background A 2006 trial in healthy medical students found that anodal slow oscillating tDCS delivered bi-frontally during slow wave sleep had an enhancing effect in declarative, but not procedural memory. Although there have been supporting animal studies, and similar findings in pathological groups, this study has not been replicated, or refuted, in the intervening years. We therefore tested these earlier results for replication using similar methods with the exception of current wave form (square in our study, nearly sinusoidal in the original). Objective/Hypothesis Our objective was to test the findings of a 2006 trial suggesting bi-frontal anodal tDCS during slow wave sleep enhances declarative memory. Methods Twelve students (mean age 25, 9 women) free of medical problems underwent two testing conditions (active, sham) in a randomized counterbalanced fashion. Active stimulation consisted of oscillating square wave tDCS delivered during early Non-Rapid Eye Movement (NREM) sleep. The sham condition consisted of setting-up the tDCS device and electrodes, but not turning it on during sleep. tDCS was delivered bi-frontally with anodes placed at F3/F4, and cathodes placed at mastoids. Current density was 0.517mA/CM2, and oscillated between zero and maximal current at a frequency of 0.75Hz. Stimulation occurred during five-five minute blocks with one-minute inter-block intervals (25 minutes total stimulation). The primary outcomes were both declarative memory consolidation measured by a paired word association test (PWA), and non-declarative memory, measured by a non-dominant finger-tapping test (FTT). We also recorded and analyzed sleep EEG. Results There was no difference in the number of paired word associations remembered before compared to after sleep [(active = 3.1±3.0SD more associations) (sham = 3.8±3.1S.D more associations)]. Finger tapping improved, (non-significantly) following active stimulation [(3.6±2.7 S.D. correctly typed sequences) compared to sham stimulation (2.3± 2.2 S.D. correctly typed sequences)]. Conclusion In this study, we failed to find improvements in declarative or performance memory and could not replicate an earlier study using nearly identical settings. Specifically we failed to find a beneficial effect on either overnight declarative or non-declarative memory consolidation via square-wave oscillating tDCS intervention applied bi-frontally during early NREM sleep. It is unclear if the morphology of the tDCS pulse is critical in any memory related improvements.
