Rapid and accurate diagnosis of tuberculosis (TB) is key to manage the disease and to control and prevent its transmission. Many established diagnostic methods suffer from low sensitivity or delay of timely results and are inadequate for rapid detection of Mycobacterium tuberculosis (MTB) in pulmonary and extra-pulmonary clinical samples. This study examined whether a real-time polymerase chain reaction (RT-PCR) assay, with a turn-a-round time of 2 h, would prove effective for routine detection of MTB by clinical microbiology laboratories. A systematic literature search was performed for publications in any language on the detection of MTB in pathological samples by RT-PCR assay. The following sources were used MEDLINE via PubMed, EMBASE, BIOSIS Citation Index, Web of Science, SCOPUS, ISI Web of Knowledge and Cochrane Infectious Diseases Group Specialised Register, grey literature, World Health Organization and Centres for Disease Control and Prevention websites. Forty-six studies met set inclusion criteria. Generated pooled summary estimates (95% CIs) were calculated for overall accuracy and bivariate meta-regression model was used for meta-analysis. Summary estimates for pulmonary TB (31 studies) were as follows: sensitivity 0.82 (95% CI 0.81–0.83), specificity 0.99 (95% CI 0.99–0.99), positive likelihood ratio 43.00 (28.23–64.81), negative likelihood ratio 0.16 (0.12–0.20), diagnostic odds ratio 324.26 (95% CI 189.08–556.09) and area under curve 0.99. Summary estimates for extra-pulmonary TB (25 studies) were as follows: sensitivity 0.70 (95% CI 0.67–0.72), specificity 0.99 (95% CI 0.99–0.99), positive likelihood ratio 29.82 (17.86–49.78), negative likelihood ratio 0.33 (0.26–0.42), diagnostic odds ratio 125.20 (95% CI 65.75–238.36) and area under curve 0.96. RT-PCR assay demonstrated a high degree of sensitivity for pulmonary TB and good sensitivity for extra-pulmonary TB. It indicated a high degree of specificity for ruling in TB infection from sampling regimes. This was acceptable, but may better as a rule out add-on diagnostic test. RT-PCR assays demonstrate both a high degree of sensitivity in pulmonary samples and rapidity of detection of TB which is an important factor in achieving effective global control and for patient management in terms of initiating early and appropriate anti-tubercular therapy.

Laparoscopic rectal surgery in obese patients is technically challenging. The technological advantages of robotic instruments can help overcome some of those challenges, but whether this translates to superior short-term outcomes is largely unknown. The aim of this study is to compare the short-term surgical outcomes of obese (BMI ≥ 30) robotic and laparoscopic rectal cancer surgery patients.

The harmful effects of female genital mutilation (FGM) on women are recognized worldwide. Although it is practiced by persons of all socioeconomic backgrounds, there are differences within countries and between communities. The aim of this study was to use the 2003 Nigeria Demographic and Health Survey data to determine the spatial distribution of the prevalence of FGM and associated risk factors. Data were available for 7,620 women; 1,673 (22.0%) interviewed had had FGM and 2,168 women had living children, of whom 485 (22.4%) daughters had undergone FGM. Unmarried women were more likely to report a lower prevalence of FGM. Modernization (education and high socioeconomic status) had minimal impact on the likelihood of FGM, but education plays an important role in the mother’s decision not to circumcise her daughter. It follows from these findings that community factors have a large effect on FGM, with individual factors having little effect on the distribution of FGM.

To compare short-term postoperative outcomes in patients undergoing robotic total mesorectal excision (TME) after the use of robotic and laparoscopic staplers. Over a 5-year period, 196 patients were divided into 2 groups according to the use of laparoscopic (LS) or robotic stapler (RS). Patient demographics and postoperative complications were compared. A total of 145 (74%) robotic TME were performed using the LS and 51 (26%) the RS. No conversions to laparoscopy or laparotomy were observed, in either group. Transection of the rectum using one or two firings was achieved in a higher proportion of RS cases (91%) compared with LS cases (60%; p < 0.001). The anastomotic leakage (AL) rate was 4% in the RS group vs. 7% in the LS group (p > 0.05). However, when three or more firings were needed for the rectal transection, the risk of AL increased (3.4% with ≤ 2 firings vs. 10.7% with ≥ 3 firings, p = 0.006). Our data confirm that multiple stapler firings for rectal transection have a major impact on AL. The robotic stapler simplifies the transaction, so that rectal division requires fewer stapler firings, with a potential reduction in the incidence of AL.

Violence against women is a global issue with estimates indicating that 35% of all women worldwide have experienced either physical and/or sexual intimate partner violence or nonpartner violence in their life time. In Malawi, 42% of ever-married women have experienced some form of violence perpetrated by their current or most recent spouse. A number of studies have investigated intimate partner violence in Malawi within the context of HIV/AIDS, girls’ sexual abuse, and psychological distress, and a few studies report on the role of sociocultural factors in influencing gender-based violence. No study has used cluster analysis to systematically analyze different levels of abuse among married women in Malawi. Using the 2015 Malawi Demographic and Health Survey data, we employed cluster analysis and multinomial logistic regression to analyze the distribution of different levels of abuse among married women in Malawi and the key attributes associated with each level of abuse. Correlates of domestic violence significantly differ by levels of abuse and are distributed as follows: controlling behavior (11.8%), general controlling behavior (GCB; 27.1%), moderate physical and emotional abuse (27.2%), and the high and complete abuse (8.5%). Alcohol consumption, ethnicity, and women working status were significantly associated with all four levels of abuse, but age and religion were only associated with controlling behavior and generalized controlling behavior. The strength of association between husband’s alcohol consumption, woman’s working status, and marriage type and domestic violence increased by level of abuse. On each of these factors, the odds of experiencing violence were lowest in the controlling behavior group and highest in the high physical and emotional abuse group. Policies and programs that are designed to tackle violence against married women in Malawi should incorporate strategies that discourage excessive alcohol consumption, promote messages that women can be bread winners, and discourage polygamous marriage.

Objectives. A national audit was performed assessing the early management of suspected inflammatory arthritis by English and Welsh rheumatology units. The aim of this audit was to measure the performance of rheumatology services against National Institute for Health and Care Excellence (NICE) quality standards (QSs) for the management of early inflammatory arthritis benchmarked to regional and national comparators for the first time in the UK. Methods. All individuals >16 years of age presenting to rheumatology services in England and Wales with suspected new-onset inflammatory arthritis were included in the audit. Information was collected against six NICE QSs that pertain to early inflammatory arthritis management. Results. We present national data for the 6354 patients recruited from 1 February 2014 to 31 January 2015; 97% of trusts and health boards in England and Wales participated in this audit. Only 17% of patients were referred by their general practitioner within 3 days of first presentation. Specialist rheumatology assessment occurred within 3 weeks of referral in 38% of patients. The target of DMARD initiation within 6 weeks of referral was achieved in 53% of RA patients; 36% were treated with combination DMARDs and 82% with steroids within the first 3 months of specialist care. Fifty-nine per cent of patients received structured education on their arthritis within 1 month of diagnosis. In total, 91% of patients had a treatment target set; the agreed target was achieved within 3 months of specialist review in only 27% of patients. Access to urgent advice via a telephone helpline was reported to be available in 96% of trusts. Conclusion. The audit has highlighted gaps between NICE standards and delivery of care, as well as substantial geographic variability.
