TL;DR: There are great variations in types of surgery performed, secondary to many factors such as surgeon’s training and socioeconomic factors, which will pose a major challenge to the health care systems.
Abstract: Millions of women are afflicted with stress urinary incontinence (SUI) and pelvic organ prolapse (POP) around the globe, and the literature is abundant with different types of surgery to correct these problems. Only recently have outcome measures been applied to research in these areas. There are great variations in types of surgery performed, secondary to many factors such as surgeon’s training and socioeconomic factors. As the population of aging women increases worldwide, it is inevitable that these women’s disorders will become more prevalent. This will pose a major challenge to the health care systems.

TL;DR: A consensus-based method for standardizing terminology for reporting outcome measures of POP surgery was developed to aid clinicians working in this area of research.
Abstract: Standardized terminology has yet to be developed for reporting the outcomes for surgery for pelvic organ prolapse (POP). This report combines the input of the Terminology and Standardization Committees of the International Urogynecological Association (IUGA) and the International Continence Society (ICS) and a joint Working Group on this topic, as well as expert external referees. The aim was to present a standardized terminology for the definitions of surgery and propose a structure for reporting the outcomes of surgical procedures for POP. An extensive drafting and review process was undertaken, as well as open review on both IUGA and ICS websites. A terminology report was developed outlining the recommended structure for reporting outcomes of surgical trials involving POP. This document does not define success and failure. The report includes patient-reported, subjective and objective outcomes to enable researchers to report on their results and compare them with other studies. A consensus-based method for standardizing terminology for reporting outcome measures of POP surgery was developed to aid clinicians working in this area of research.

TL;DR: The establishment of breeding lines of transgenic mice that reproducibly develop prostate cancer provides an animal model system to study the molecular basis of transformation of normal prostatic cells and the factors influencing the progression to metastatic prostate cancer.
Abstract: Progress toward understanding the biology of prostate cancer has been slow due to the few animal research models available to study the spectrum of this uniquely human disease. To develop an animal model for prostate cancer, several lines of transgenic mice were generated by using the prostate-specific rat probasin promoter to derive expression of the simian virus 40 large tumor antigen-coding region. Mice expressing high levels of the transgene display progressive forms of prostatic disease that histologically resemble human prostate cancer, ranging from mild intraepithelial hyperplasia to large multinodular malignant neoplasia. Prostate tumors have been detected specifically in the prostate as early as 10 weeks of age. Immunohistochemical analysis of tumor tissue has demonstrated that dorsolateral prostate-specific secretory proteins were confined to well-differentiated ductal epithelial cells adjacent to, or within, the poorly differentiated tumor mass. Prostate tumors in the mice also display elevated levels of nuclear p53 and a decreased heterogeneous pattern of androgen-receptor expression, as observed in advanced human prostate cancer. The establishment of breeding lines of transgenic mice that reproducibly develop prostate cancer provides an animal model system to study the molecular basis of transformation of normal prostatic cells and the factors influencing the progression to metastatic prostate cancer.

TL;DR: The central role of catalase in the VBNC response of some bacteria, including its genetic regulation, is described and a variety of interesting chemical and biological factors have been shown to allow resuscitation, including extracellular resuscitation-promoting proteins, a novel quorum-sensing system and interactions with amoeba.
Abstract: Many bacteria, including a variety of important human pathogens, are known to respond to various environmental stresses by entry into a novel physiological state, where the cells remain viable, but are no longer culturable on standard laboratory media. On resuscitation from this ‘viable but nonculturable’ (VBNC) state, the cells regain culturability and the renewed ability to cause infection. It is likely that the VBNC state is a survival strategy, although several interesting alternative explanations have been suggested. This review describes the VBNC state, the various chemical and physical factors known to induce cells into this state, the cellular traits and gene expression exhibited by VBNC cells, their antibiotic resistance, retention of virulence and ability to attach and persist in the environment, and factors that have been found to allow resuscitation of VBNC cells. Along with simple reversal of the inducing stresses, a variety of interesting chemical and biological factors have been shown to allow resuscitation, including extracellular resuscitation-promoting proteins, a novel quorum-sensing system (AI-3) and interactions with amoeba. Finally, the central role of catalase in the VBNC response of some bacteria, including its genetic regulation, is described.

TL;DR: Overall, the review provides some support for the widespread recommendation that PFMT be included in first-line conservative management programmes for women with stress, urge, or mixed, urinary incontinence.
Abstract: Background Pelvic floor muscle training is the most commonly used physical therapy treatment for women with stress urinary incontinence (SUI). It is sometimes also recommended for mixed and, less commonly, urgency urinary incontinence. Objectives To determine the effects of pelvic floor muscle training for women with urinary incontinence in comparison to no treatment, placebo or sham treatments, or other inactive control treatments. Search methods We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL) (1999 onwards), MEDLINE (1966 onwards) and MEDLINE In-Process (2001 onwards), and handsearched journals and conference proceedings (searched 15 April 2013) and the reference lists of relevant articles. Selection criteria Randomised or quasi-randomised trials in women with stress, urgency or mixed urinary incontinence (based on symptoms, signs, or urodynamics). One arm of the trial included pelvic floor muscle training (PFMT). Another arm was a no treatment, placebo, sham, or other inactive control treatment arm. Data collection and analysis Trials were independently assessed by two review authors for eligibility and methodological quality. Data were extracted then cross-checked. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook for Systematic Reviews of Interventions. Trials were subgrouped by diagnosis of urinary incontinence. Formal meta-analysis was undertaken when appropriate. Main results Twenty-one trials involving 1281 women (665 PFMT, 616 controls) met the inclusion criteria; 18 trials (1051 women) contributed data to the forest plots. The trials were generally small to moderate sized, and many were at moderate risk of bias, based on the trial reports. There was considerable variation in the interventions used, study populations, and outcome measures. There were no studies of women with mixed or urgency urinary incontinence alone. Women with SUI who were in the PFMT groups were 8 times more likely than the controls to report that they were cured (46/82 (56.1%) versus 5/83 (6.0%), RR 8.38, 95% CI 3.68 to 19.07) and 17 times more likely to report cure or improvement (32/58 (55%) versus 2/63 (3.2%), RR 17.33, 95% CI 4.31 to 69.64). In trials in women with any type of urinary incontinence, PFMT groups were also more likely to report cure, or more cure and improvement than the women in the control groups, although the effect size was reduced. Women with either SUI or any type of urinary incontinence were also more satisfied with the active treatment, while women in the control groups were more likely to seek further treatment. Women treated with PFMT leaked urine less often, lost smaller amounts on the short office-based pad test, and emptied their bladders less often during the day. Their sexual outcomes were also better. Two trials (one small and one moderate size) reported some evidence of the benefit persisting for up to a year after treatment. Of the few adverse effects reported, none were serious. The findings of the review were largely supported by the summary of findings tables, but most of the evidence was down-graded to moderate on methodological grounds. The exception was 'Participant perceived cure' in women with SUI, which was rated as high quality. Authors' conclusions The review provides support for the widespread recommendation that PFMT be included in first-line conservative management programmes for women with stress and any type of urinary incontinence. Long-term effectiveness of PFMT needs to be further researched.
