mRNAs showing highest levels of fold-change included several which code for membrane-localised proteins and receptors (Thbs1, Tfrc1, Ackr3, Extl1). CONCLUSIONS Growth-arrest induced by polyamine deprivation was associated with significant alterations in levels of mRNAs associated with cell cycle progression, DNA repair, RNA splicing, ER trafficking and membrane signalling as well as p53 and apoptosis-related pathways.Even though several clinics serve patients in more than one stage (e.g., visit nurse and then visit doctor) and employ multiple providers in each stage, most of the previous work on appointment system design considers a simplified single-stage single-server clinic. Motivated by a real-life clinic setting, this paper aims to determine the schedule configuration of a hybrid appointment system (i.e., the number of pre-booking and same-day time slots reserved for a physician along with their positions in the schedule) for a two-stage multi-server clinic. A stochastic optimization model is developed to obtain a schedule configuration that minimizes the expected total cost - a weighted sum of excessive patient waiting time, resource idle time, resource overtime, and denied appointment requests. Owing to its computational complexity, we estimate the expected total cost using the sample average approximation method. The proposed model is verified and validated using small test instances and subject matter experts. A case study of a family medicine clinic in Pennsylvania is used to illustrate the proposed approach. The schedule generated by the proposed model results in a significantly lower expected cost compared to the approximated single-stage system's best schedule configuration and clinic's existing configuration. Further, sensitivity analysis is conducted to assess the impacts of no-show rate, service time variation, and cost ratios on the schedule configuration. Our findings demonstrate that the schedule configuration is sensitive to changes in the average no-show rate and cost ratios but is not significantly impacted by service time variation. Several managerial insights are also drawn from our analysis. Finally, we provide directions for future research that also highlights the potential to use the revenue management approach to address the problem under study.PURPOSE Complex abdominal wall repair (CAWR) in a contaminated operative field is a challenge. Available literature regarding long-term outcomes of CAWR comprises studies that often have small numbers and heterogeneous patient populations. This study aims to assess long-term outcomes of modified-ventral hernia working group (VHWG) grade 3 repairs. Because the relevance of hernia recurrence (HR) as the primary outcome for this patient group is contentious, the need for further hernia surgery (FHS) was also assessed in relation to long-term survival. METHODS A retrospective cohort study with a single prospective follow-up time-point nested in a consecutive series of patients undergoing CAWR in two European national intestinal failure centers. RESULTS In long-term analysis, 266 modified VHWG grade 3 procedures were included. The overall HR rate was 32.3%. The HR rates for non-crosslinked biologic meshes and synthetic meshes when fascial closure was achieved were 20.3% and 30.6%, respectively. The rates of FHS were 7.2% and 16.7%, and occurred only within the first 3 years. Bridged repairs showed poorer results (fascial closure 22.9% hernia recurrence vs bridged 57.1% recurrence). Overall survival was relatively good with 80% en 70% of the patients still alive after 5 and 10 years, respectively. In total 86.6% of the patients remained free of FHS. CONCLUSIONS In this study of contaminated CAWR, non-crosslinked biologic mesh shows better results than synthetic mesh. Bridging repairs with no posterior and/or anterior fascial closure have a higher recurrence rate. The overall survival was good and the majority of patients remained free of additional hernia surgery.Secondary distribution of HIV self-tests to sexual partners is acceptable but concerns remain about reactions if a partner tests HIV-positive. selleck chemicals We report on 14 participants whose sexual partners tested HIV-positive during the "I'll Show You Mine" Study, a randomized controlled trial (N = 272) of HIV self- and partner-testing among men who have sex with men (MSM) and transgender women (TGW). All 14 were MSM and racial/ethnic minorities, mean age was 36.6 years; 86% were gay-identified. Twenty-four partners tested positive; about half were new partners. Six participants had multiple partners test positive. During in-depth interviews with 10 of these participants, they reported their partners' reactions ranged from tearful and worried among those whose result was unexpected, to resignation among those who suspected a positive result, to nonchalance among partners who participants concluded knew of their HIV infection. After testing, some HIV-positive partners disclosed prior knowledge of their status. No partner reacted violently. Participants typically comforted their partners and encouraged confirmatory testing. Four participants had anal intercourse with partners who tested positive. Participants and partners were able to effectively handle situations in which the partner tested HIV-positive.We examined the prevalence of intimate partner violence (IPV) perpetration and characteristics of HIV-infected male perpetrators. The cross-sectional study was conducted in Vietnam with male antiretroviral treatment clients (N = 1099; mean age = 40.2 years). Bivariable associations were tested between psychological or physical/sexual IPV perpetration in the last 12 months and sociodemographic, psychosocial, and sexual behavioral factors using prevalence ratios. Factors significant at p  less then  0.10 were entered in multivariable models for each IPV outcome using a modified Poisson approach. Results showed 15.6% (N = 171/1099) reported perpetrating psychological IPV and 7.6% (N = 84/1099) perpetrating physical/sexual IPV in the last 12 months. HIV risk behaviors, including hazardous drinking and multiple sexual partners, having witnessed interparental violence as a child, and depressive symptoms were associated with perpetrating IPV. HIV interventions targeting HIV-infected men in Vietnam should intervene on IPV perpetration by addressing the co-occurring factors of sexual risk, depression, alcohol use, and child maltreatment that are correlated with IPV.
