RESUMEN

Women need multipurpose prevention technologies (MPTs) to simultaneously prevent sexually transmitted infections (STIs), including HIV, with or without contraception. User feedback early in product development is critical for maximizing uptake and continuation. Our global online survey (April 2017-December 2018) explored women's opinions about MPT formulations in development (e.g., fast-dissolving vaginal inserts, vaginal films, intravaginal rings, injectables, implants), preferences for long-acting or "on-demand" methods, and interest in a contraceptive MPT versus products for HIV/STI prevention alone. Of the 630 women in our final analysis (mean 30 years old; range 18-49), 68% were monogamous, 79% completed secondary education, 58% had ≥ 1 child, 56% were from sub-Saharan Africa and 82% preferred a cMPT versus HIV/STI prevention alone. There were no clear preferences for any specific product or product type (long-acting, on-demand, daily). No single product will appeal everyone, however, adding contraception is likely to increase uptake of HIV/STI prevention methods for most women.


RESUMEN: Las mujeres necesitan tecnologías de prevención multipropósito (TPM) para prevenir simultáneamente las infecciones de transmisión sexual (ITS), incluido el VIH, con o sin anticoncepción. Las opiniones de los usuarios cuando un producto comienza a desarrollarse son fundamentales para maximizar la adopción y continuación de dicho producto. Nuestra encuesta global realizada en internet (abril de 2017­diciembre de 2018) exploró las opiniones de las mujeres sobre diferentes fórmulas o dispositivos de TPM que se están desarrollando (ej., insertos vaginales de disolución rápida, láminas vaginales, anillos intravaginales, inyectables, implantes). En esta encuesta se indagó acerca de las preferencias en términos de período de acción (prolongado o breve) y propósito del uso (anticonceptivo, productos para la prevención del VIH/ITS, o ambos). De las 630 mujeres (media de 30 años; rango 18­49) en el análisis final, el 68% eran monógamas, el 79% completaron la educación secundaria, el 58% tenían ≥ 1 hijo, el 56% eran del África subsahariana y el 82% preferían una TPM con componente anticonceptivo en vez de un producto para la prevención de VIH/ITS exclusivamente. No hubo preferencias claras por ningún producto o tipo de producto específico (de acción prolongada, de acción breve, de uso diario). Ningún producto por sí solo logró abarcar todas las preferencias; sin embargo, es probable que la inclusión de métodos anticonceptivos en una TPM aumente el uso de métodos de prevención del VIH/ITS en la mayoría de las mujeres.

RESUMEN

OBJECTIVE(S): Effective contraceptive method use is important for HIV-positive women to meet fertility goals, prevent unintended pregnancy and reduce risk of vertical HIV transmission. Our objective was to evaluate factors associated with HIV-positive women's contraceptive method use at last coitus defined as more effective [Tier 1 and 2 methods (T1/2)] versus less effective [Tier 3 or no method (T3/none)] by the US Medical Eligibility Criteria for contraception use. STUDY DESIGN: HIV-positive women, recruited from an HIV clinic in Atlanta, Georgia, between 2013 and 2014, completed a survey of demographic, clinical and reproductive health characteristics surrounding contraception. We examined the relationship between survey responses and contraceptive method use at last coitus using χ2 tests and multivariate logistic regression. RESULTS: Thirty-one percent of this HIV-positive and predominantly African-American (90%) cohort reported usage of T1/2 methods. T1/2 methods use was higher among younger women [adjusted odds ratio (aOR)=.90, p=.008] and those in noncommitted relationships (aOR =.32, p=.027). Only 21% reported dual method use at last intercourse. Fifty-three percent and 31% reported having heard of the intrauterine device and implant, respectively. Misconceptions about contraception were common. CONCLUSIONS: The use of T1/2 methods was more common in this cohort than in the general African-American population, but overall use and dual method use can still be improved, particularly among older women and those in noncommitted relationships. IMPLICATIONS: As this population had low awareness and usage of T1/2 methods and expressed many misconceptions, reoccurring contraceptive counseling may be helpful. Providers should address patient-level barriers, pregnancy intentions, and the importance of dual method and T1/2 method use.

RESUMEN

BACKGROUND: In the Model for End-Stage Liver Disease (MELD) system, patients with "MELD exceptions" points may have unfair privilege in the competition for liver grafts. Furthermore, organ distribution following identical ABO blood types may also result in unjust organ allocation. The aim of this study was to investigate access to liver transplantation in a tertiary Brazilian center, regarding "MELD exceptions" situations and among ABO-blood groups. METHODS: A total of 465 adult patients on the liver waitlist from August 2015 to August 2016 were followed up until August 2017. Patients were divided into groups according to ABO-blood type and presence of "exceptions points." RESULTS: No differences in outcomes were observed among ABO-blood groups. However, patients from B and AB blood types spent less time on the list than patients from A and O groups (median, 46, 176, 415, and 401 days, respectively; P = .03). "Exceptions points" were granted for 141 patients (30.1%), hepatocellular carcinoma being the most common reason (52.4%). Patients with "exceptions points" showed higher transplantation rate, lower mortality on the list, and lower delta-MELD than non-exceptions patients (56.7% vs 19.1% [P < .01]; 18.4% vs 38.5% [P < .01], and 2.0 ± 2.6 vs 6.9 ± 7.0 [P < .01], respectively). Patients with refractory ascites had a higher mortality rate than those with other "exceptions" or without (48%). CONCLUSIONS: The MELD system provides equal access to liver transplantation among ABO-blood types, despite shorter time on the waitlist for AB and B groups. The current MELD exception system provides advantages for candidates with "exception points," resulting in superior outcomes compared with those without exceptions.

RESUMEN

BACKGROUND: The Model for End-Stage Liver Disease (MELD) system reliably predicts mortality in cirrhotic patients. However, the etiology of liver disease and presence of portal vein thrombosis are not directly taken into account in MELD score. Its impact on the outcomes of patients on the waiting list is still unclear. The aim of this study was to investigate mortality and access to transplantation regarding etiology of liver disease and portal vein thrombosis (PVT). METHODS: A total of 465 adult patients on the liver waiting list from August 2015 to August 2016 were followed up until August 2017. Patients were divided into groups according to the etiology of liver disease and presence of PVT. RESULTS: The most frequent etiologies were hepatitis C (26.88%), alcoholic cirrhosis (26.02%) and cryptogenic cirrhosis (10.75%). Death while on the waiting list occurred in 168 patients (36.1%) and was more frequent in nonalcoholic steatohepatitis (NASH, 65.4%) and alcoholic cirrhosis (41.3%). A total of 142 (30.5%) patients underwent transplantation and viral, autoimmune, and biliary diseases showed higher proportion of transplantation (36.3%, 53.8%, and 34%, respectively; P < .01). Mean delta-MELD at the study endpoint was higher in patients with autoimmune hepatitis, biliary diseases, and NASH (8.3 ± 7.2, 8.3 ± 9.1, and 7.5 ± 9.1, respectively; P < .01). A total 77 patients (16.7%) presented PVT. There was no significant difference in outcomes between patients with and without PVT. CONCLUSIONS: Patients with NASH and alcoholic liver disease had higher mortality while on the waiting list, whereas patients with viral and autoimmune hepatitis had higher transplantation rate. Outcomes were not influenced by PVT.

RESUMEN

BACKGROUND: Rifamycin antibiotics are commonly used for treatment of tuberculosis, but may reduce the effectiveness of hormonal contraception (HC). OBJECTIVES: To determine whether interactions between rifamycins and HC result in decreased effectiveness or increased toxicity of either therapy. SEARCH STRATEGY: We searched MEDLINE, Embase, Cochrane and clinicaltrials.gov through May 2017. SELECTION CRITERIA: We included trials, cohort, and case-control studies addressing pregnancy rates, pharmacodynamics or pharmacokinetic (PK) outcomes when HC and rifamycins were administered together versus apart. Of 7291 original records identified, 11 met inclusion criteria after independent review by two authors. DATA COLLECTION AND ANALYSIS: Two authors independently abstracted study details and assessed study quality using the United States Preventive Services Task Force grading system. Findings are reported descriptively. MAIN RESULTS: Studies only addressed combined oral contraceptives (COCs) and none reported pregnancy rates. Quality ranged from good to poor. Rifampin increased the frequency of ovulation in two of four studies, and reduced estrogen and/or progestin exposure in five studies. Rifabutin led to smaller PK changes than rifampin in two studies. In one study each, rifaximin and rifalazil did not alter hormone PK. CONCLUSIONS: No studies evaluated pregnancy risk or non-oral HCs. PK and ovulation outcomes support a clinically concerning drug interaction between COCs and rifampin, and to a lesser extent rifabutin. Data are limited for other rifamycins. TWEETABLE ABSTRACT: Rifampin and rifabutin reduce systemic exposure of oral contraceptives, but no studies have evaluated pregnancy risk.

RESUMEN

This cross-sectional study sought to determine factors associated with sterilization among HIV-positive US women. HIV-positive women aged 18-45 completed an Audio Computer Assisted Self Interview (ACASI) questionnaire. Chi-square tests and multivariable logistic regression evaluated factors associated with sterilization. The median age of the 187 participants was 37, the majority had at least a high school education, and 88% were African American. Nearly a quarter (22%) of women had undergone sterilization at an average age of 25; of these women, 71% cited their HIV-positive status as an important factor in deciding to have a tubal ligation, 22% expressed desire for future children, 32% reported sterilization regret, and 20% reported feeling pressure to undergo sterilization. In multivariable analysis, factors significantly associated with sterilization included non-African American race, no desire for future pregnancy, having heard of any birth control methods making it harder to get pregnant in the future, belief that women should take a break from hormonal methods every few years, and having had a child born with HIV. While almost a quarter of this HIV-positive group was sterilized, many during the height of the early HIV epidemic, a large proportion of sterilized women expressed sterilization regret. Counseling messages for sterilized HIV-positive women should be sensitive to the fact that women may have regret regarding a decision that, in some cases, may historically have been part of provider recommendations to prevent vertical transmission of HIV. Improved knowledge about contraceptive options such as the IUD and implant is needed among HIV-positive women.

RESUMEN

As many as 25 % of colorectal cancer (CRC) patients have liver metastases at presentation. However, the optimal strategy for resectable synchronous colorectal liver metastasis remains controversial. Despite the increasing use of laparoscopy in colorectal and liver resections, combined laparoscopic resection of the primary CRC and synchronous liver metastasis is rarely performed. The potential benefits of this approach are the possibility to perform a radical operation with small incisions, earlier recovery, and reduction in costs. The aim of this study was to review the literature on feasibility and short-term results of simultaneous laparoscopic resection. We conducted a systematic search of all articles published until February 2013. Search terms included: hepatectomy [Mesh], "liver resection," laparoscopy [Mesh], hand-assisted laparoscopy [Mesh], surgical procedures, minimally invasive [Mesh], colectomy [Mesh], colorectal neoplasms [Mesh], and "colorectal resections." No randomized trials are available. All data have been reported as case reports, case series, or case-control studies. Thirty-nine minimally invasive simultaneous resections were identified in 14 different articles. There were 9 (23 %) major hepatic resections. The most performed liver resection was left lateral sectionectomy in 26 (67 %) patients. Colorectal resections included low rectal resections with total mesorectal excision, right and left hemicolectomies, and anterior resections. Despite the lack of high-quality evidence, the laparoscopic combined procedure appeared to be feasible and safe, even with major hepatectomies. Good patient selection and refined surgical technique are the keys to successful simultaneous resection. Simultaneous left lateral sectionectomy associated with colorectal resection should be routinely proposed.

RESUMEN

STUDY OBJECTIVE: To determine if there is an association between pediatric ovarian malignancies and elevated platelet counts: DESIGN: Retrospective chart review. SETTING: Large referral children's hospital. PARTICIPANTS: 154 patients taken to the operating room between February 1993 and February 2006 with an adnexal mass where ovarian tissue was submitted for pathological analysis. MAIN OUTCOME MEASURES: The principle outcome was the presence of ovarian malignancy. RESULTS: We found that there is an increase in thrombocytosis among individuals with ovarian malignancy, with as high as 33% of those with ovarian germ cell tumors demonstrating preoperative thrombocytosis. CONCLUSION: These results suggest that thrombocytosis may be a useful marker for ovarian malignancy in this population. Further studies will be needed to determine if there is any prognostic value to thrombocytosis among these patients, with a potential value for counseling and future intervention based on these findings.

RESUMEN

This study examined behavioral characteristics distinguishing psychiatric geriatric patients requiring alternative levels of care. Multiple behavior rating scales were administered to 389 elderly patients, concurrent with, but independent from, placement decisions of a clinical team. A discriminant function analysis revealed loadings on care needed, activities of daily living, and disorientation as factors discriminating skilled nursing from intermediate care patients. Orthogonal function loadings characterized psychiatric patients as having poorer communication skills, being less cooperative, manifesting greater psychopathology, and showing more seclusiveness. Further analysis provided by a cross-validation study support the utility of behavior rating scales for simulating outcome actions of decision makers.

RESUMEN

A study was designed to measure the impact of intra-hospital relocation upon elderly patients transferred to intermediate, skilled nursing, or psychiatric care facilities. The subjects were 389 elderly residents of a psychiatric hospital. Their mean age was 76.2 years, and mean length of hospitalization 22.4 years. A before-and-after analysis was made of behavior rating scores, and the mortality rate was compared with baseline values. The findings indicated that, for this type of reorganization, no deterioration was evident in the measured behaviors, nor did the move cause sufficient stress to have a substantial impact on mortality. It was concluded that, contrary to numerous reports in the literature, the mass relocation of elderly patients for the purpose of delivering more appropriate treatment services does not necessarily have detrimental effects. Additional research is required to account for outcomes related to the interaction between more specific personal characteristics and environmental components.
