Surgery for women with apical vaginal prolapse.

Within the context of heavy menstrual bleeding, pandemics impact upon women's assessment and treatment by healthcare providers. To summarise the evidence from Cochrane Reviews evaluating interventions for heavy menstrual bleeding that are commonly available during pandemics. We sought published Cochrane Reviews, evaluating interventions that can continue during pandemics for women with heavy menstrual bleeding with no known underlying cause. We identified Cochrane Reviews by searching the Cochrane Database of Systematic Reviews in June 2020. The primary outcome was menstrual bleeding. Secondary outcomes included quality of life, patient satisfaction, side effects, and serious adverse events. We undertook the selection of systematic reviews, data extraction, and quality assessment in duplicate. We resolved any disagreements by discussion. We assessed review quality using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) 2 tool, and the certainty of the evidence for each outcome using GRADE methods. We included four Cochrane Reviews, with 11 comparisons, data from 44 randomised controlled trials (RCTs), and 3196 women. We assessed all the reviews to be high quality. Non-steroidal anti-inflammatory drugs (NSAIDs) NSAIDs may be more effective in reducing heavy menstrual bleeding than placebo (mean difference (MD) -124 mL per cycle, 95% confidence interval (CI) -186 to -62 mL per cycle; 1 RCT, 11 women; low-certainty evidence). Mefenamic acid may be similar to naproxen (MD 21 mL per cycle, 95% CI -6 to 48 mL per cycle; 2 RCTs, 61 women; low-certainty evidence), and NSAIDs may be similar to combined hormonal contraceptives for heavy menstrual bleeding (MD 25 mL per cycle, 95% CI -22 to 73 mL per cycle; 1 RCT, 26 women; low-certainty evidence). NSAIDs may be be less effective in reducing menstrual bleeding than antifibrinolytics (relative risk (RR) 0.70, 95% CI 0.58 to 0.85; 2 RCTs, 161 women; low-certainty evidence). We are uncertain whether NSAIDs reduce menstrual blood loss more than short-cycle progestogens (RR 0.80, 95% CI 0.49 to 1.32; 1 RCT 32 women; very low-certainty evidence). Antifibrinolytics Antifibrinolytics appear to be more effective in reducing heavy menstrual bleeding than placebo (MD -53 mL per cycle, 95% CI -63 to -44 mL per cycle; 4 RCTs, 565 women; moderate-certainty evidence). Antifibrinolytics may be similar to placebo on the incidence of side effects (RR 1.05, 95% CI 0.93 to 1.18; 1 RCT, 297 women; low-certainty evidence), and they are probably similar on the incidence of serious adverse events (thrombotic events; RR 0.10, 95% CI 0.00 to 2.46; 2 RCT, 468 women; moderate-certainty evidence). Antifibrinolytics may be more effective in reducing heavy menstrual bleeding than short-cycle progestogen (MD -111 mL per cycle, 95% CI -178 mL to -44 mL per cycle; 1 RCT, 46 women; low-certainty evidence). We are uncertain whether antifibrinolytics are similar to short-cycle progestogens on quality of life (RR 1.67, 95% CI 0.76 to 3.64; 1 RCT, 44 women; very low-certainty evidence), patient satisfaction (RR 0.91, 95% CI 0.59 to 1.39; 1 RCT, 42 women; very low-certainty evidence), or side effects (RR 0.85, 95% CI 0.65 to 1.12; 3 RCTs, 211 women; very low-certainty evidence). We are uncertain whether antifibrinolytics are more effective in reducing heavy menstrual bleeding when compared with long-cycle progestogen (MD -9 points per cycle, 95% CI -30 to 12 points per cycle; 2 RCTs, 184 women; low-certainty evidence). Antifibrinolytics may increase self-reported improvement in menstrual bleeding when compared with long-cycle medroxyprogesterone acetate (RR 1.32, 95% CI 1.08 to 1.61; 1 RCT, 94 women; low-certainty evidence). Antifibrinolytics may be similar to long-cycle progestogens on quality of life (MD 5, 95% CI -2.49 to 12.49; 1 RCT, 90 women; low-certainty evidence). We are uncertain whether antifibrinolytics are similar to long-cycle progestogens on side effects (RR 0.58, 95% CI 0.33 to 1.00; 2 RCTs, 184 women; very low-certainty evidence). There were no trials comparing antifibrinolytics to combined hormonal contraceptives. Combined hormonal contraceptives Combined hormonal contraceptives appear to be more effective for heavy menstrual bleeding than placebo or no treatment (RR 13.25, 95% CI 2.94 to 59.64; 2 RCTs, 363 women; moderate-certainty evidence). Combined hormonal contraceptives are probably similar to placebo on the incidence of side effects (RR 1.53, 95% CI 0.90 to 2.60; 2 RCTs, 411 women; moderate-certainty evidence). Progestogens There were no trials comparing progestogens to placebo. Limitations in the evidence included risk of bias in the primary RCTs, inconsistency between the primary RCTs, and imprecision in effect estimates. There is moderate-certainty evidence that antifibrinolytics and combined hormonal contraceptives reduce heavy menstrual bleeding compared with placebo. There is low-certainty evidence that NSAIDs reduce heavy menstrual bleeding compared with placebo. There is low-certainty evidence that antifibrinolytics are more effective in reducing heavy menstrual bleeding when compared with NSAIDs and short-cycle progestogens, but we are unable to draw conclusions about the effects of antifibrinolytics compared to long-cycle progestogens, on low-certainty evidence.

Anticoagulation for the long-term treatment of venous thromboembolism in people with cancer.

There is currently moderate- to very low-certainty evidence available regarding the benefits and harms of maintenance therapy in people with CLL. Anti-CD20 mAbs maintenance improved PFS, but also increased grade 3/4 AEs and all AEs. IMiD maintenance had a large effect on PFS, but also increased grade 3/4 AEs. However, none of the above-mentioned maintenance interventions show differences in OS between the maintenance and control groups. The effects of alemtuzumab maintenance are uncertain, coupled with a warning for drug-related infectious toxicity. We found no studies evaluating other novel maintenance interventions, such as B-cell receptor inhibitors, B-cell leukaemia-2/lymphoma-2 inhibitors, or obinutuzumab.

Early scans probably reduce short term maternal anxiety. Later scans may reduce labour induction for post-maturity. They may improve detection of major fetal abnormalities and increase the number of women who choose termination of pregnancy for this reason. They may also reduce the number of undetected twin pregnancies. All these findings accord with observational data. Neither type of scan appears to alter other important maternal or fetal outcomes, but our review may underestimate the effect in modern practice because trials were mostly from relatively early in the development of the technology, and many control participants also had scans. The trials were also underpowered to show an effect on other important maternal or fetal outcomes.

Peritonitis is one of the limiting factors for the growth of peritoneal dialysis (PD) worldwide and is a major cause of technique failure. Several studies have examined the effectiveness of various catheter-related interventions for lowering the risk of PD-related peritonitis. This is an update of a review first published in 2004. To evaluate the role of different catheter implantation techniques and catheter types in lowering the risk of PD-related peritonitis in PD patients. We searched the Cochrane Kidney and Transplant Register of Studies up to 15 January 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. Studies comparing different catheter insertion techniques, catheter types, use of immobilisation techniques and different break-in periods were included. Studies of different PD sets were excluded. Two authors independently assessed study quality and extracted data. Statistical analyses were performed using a random effects model and the results expressed as risk ratio (RR) with 95% confidence intervals (CI). Forty-two studies (3144 participants) were included: 18 evaluated techniques of catheter implantation, 22 examined catheter types, one assessed an immobiliser device, and one examined break-in period. In general, study quality was variable and almost all aspects of study design did not fulfil CONSORT standards for reporting.Catheter insertion by laparoscopy compared with laparotomy probably makes little or no difference to the risks of peritonitis (RR 0.90, 95% CI 0.59 to 1.35; moderate certainty evidence), exit-site/tunnel infection (RR 1.00, 95% CI 0.43 to 2.31; low certainty evidence), catheter removal/replacement (RR 1.20, 95% CI 0.77 to 1.86; low certainty evidence), technique failure (RR 0.71, 95% CI 0.47 to 1.08; low certainty evidence), and death (all causes) (RR 1.26, 95% CI 0.72 to 2.20; moderate certainty evidence). It is uncertain whether subcutaneous burying of catheter increases peritonitis (RR 1.16, 95% CI 0.37 to 3.60; very low certainty evidence). Midline insertion compared to lateral insertion probably makes little or no difference to the risks of peritonitis (RR 0.65, 95% CI 0.32 to 1.33; moderate certainty evidence) and may make little or no difference to exit-site/tunnel infection (RR 0.56, 95% CI 0.12 to 2.58; low certainty evidence). Percutaneous insertion compared with open surgery probably makes little or no difference to the exit-site/tunnel infection (RR 0.16, 95% CI 0.02 to 1.30; moderate certainty evidence).Straight catheters probably make little or no difference to the risk of peritonitis (RR 1.04, 95% CI 0.82 to 1.31; moderate certainty evidence), peritonitis rate (RR 0.91, 95% CI 0.68 to 1.21; moderate certainty evidence), risk of exit-site infection (RR 1.12, 95% CI 0.94 to 1.34; moderate certainty evidence), and exit-site infection rate (RR 1.05, 95% CI 0.77 to 1.43; moderate certainty evidence) compared to coiled catheter. It is uncertain whether straight catheters prevent catheter removal or replacement (RR 1.11, 95% CI 0.73 to 1.66; very low certainty evidence) but straight catheters probably make little or no difference to technique failure (RR 0.82, 95% CI 0.51 to 1.31; moderate certainty evidence) and death (all causes) (RR 0.95, 95% CI 0.62 to 1.46; low certainty evidence) compared to coiled catheter. Tenckhoff catheter with artificial curve at subcutaneous tract compared with swan-neck catheter may make little or no difference to peritonitis (RR 1.29, 95% CI 0.85 to 1.96; low certainty evidence) and incidence of exit-site/tunnel infection (RR 0.96, 95% CI 0.77 to 1.21; low certainty evidence) but may slightly improve exit-site infection rate (RR 0.67, 95% CI 0.50 to 0.90; low certainty evidence). There is no strong evidence that any catheter-related intervention, including the use of different catheter types or different insertion techniques, reduces the risks of PD peritonitis or other PD-related infections, technique failure or death (all causes). However, the numbers and sizes of studies were generally small and the methodological quality of available studies was suboptimal, such that the possibility that a particular catheter-related intervention might have a beneficial effect cannot be completely ruled out with confidence.

This review shows that antacids, sucralfate, and H2 receptor antagonists might be more effective in preventing upper GI bleeding in ICU patients compared with placebo or no prophylaxis. The effect estimates of any treatment versus no prophylaxis on nosocomial pneumonia were consistent with benefits and harms. Evidence of low certainty suggests that proton pump inhibitors might be more effective than H2 receptor antagonists. Therefore, patient-relevant benefits and especially harms of H2 receptor antagonists compared with proton pump inhibitors need to be assessed by larger, high-quality RCTs to confirm the results of previously conducted, smaller, and older studies.

Small numbers of studies and participants in each comparison limited our confidence in the evidence. Sclerosing agents were more effective than placebo for resolution or improvement of telangiectasias but also caused more adverse events (moderate-certainty evidence), and may result in more pain (low-certainty evidence). There was no evidence of a benefit in resolution or improvement for any sclerosant compared to another or to laser. There may be more resolution or improvement of telangiectasias in the combined laser and polidocanol group compared to polidocanol alone (low-certainty evidence). There may be differences between treatments in adverse events and pain. Compared to other sclerosing agents polidocanol probably causes less pain; STS resulted in more hyperpigmentation, matting and probably pain; foam may cause more matting (low-certainty evidence); laser treatment may result in less hyperpigmentation (moderate-certainty evidence). Further well-designed studies are required to provide evidence for other available treatments and important outcomes (such as recurrence, time to resolution and delayed adverse events); and to improve our confidence in the identified comparisons.

Interventions for preventing venous thromboembolism in adults undergoing knee arthroscopy.

People with AMD may experience some delay in progression of the disease with multivitamin antioxidant vitamin and mineral supplementation. This finding was largely drawn from one large trial, conducted in a relatively well-nourished American population. We do not know the generalisability of these findings to other populations. Although generally regarded as safe, vitamin supplements may have harmful effects. A systematic review of the evidence on harms of vitamin supplements is needed. Supplements containing lutein and zeaxanthin are heavily marketed for people with age-related macular degeneration but our review shows they may have little or no effect on the progression of AMD.

Compared with no drain use, it is unclear whether routine drain use has any effect on mortality at 30 days or postoperative complications after pancreatic surgery. Compared with no drain use, low-certainty evidence suggests that routine drain use may reduce mortality at 90 days. Compared with a passive drain, the evidence is very uncertain about the effect of an active drain on mortality at 30 days or postoperative complications. Compared with late drain removal, early drain removal may reduce intra-abdominal infection rate, morbidity, and length of hospital stay for people with low risk of postoperative pancreatic fistula, but the evidence is very uncertain.

Cardiovascular (CV) disease is the leading cause of death in dialysis patients, and strongly associated with fluid overload and hypertension. It is plausible that low dialysate [Na+] may decrease total body sodium content, thereby reducing fluid overload and hypertension, and ultimately reducing CV morbidity and mortality. This review evaluated harms and benefits of using a low (< 138 mM) dialysate [Na+] for maintenance haemodialysis (HD) patients. We searched the Cochrane Kidney and Transplant Register of Studies up to 7 August 2018 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. Randomised controlled trials (RCTs), both parallel and cross-over, of low (< 138 mM) versus neutral (138 to 140 mM) or high (> 140 mM) dialysate [Na+] for maintenance HD patients were included. Two investigators independently screened studies for inclusion and extracted data. Statistical analyses were performed using random effects models, and results expressed as risk ratios (RR) for dichotomous outcomes, and mean differences (MD) or standardised MD (SMD) for continuous outcomes, with 95% confidence intervals (CI). Confidence in the evidence was assessed using GRADE. We included 12 studies randomising 310 patients, with data available for 266 patients after dropout. All but one study evaluated a fixed concentration of low dialysate [Na+], and one profiled dialysate [Na+]. Three studies were parallel group, and the remaining nine cross-over. Of the latter, only two used a washout between intervention and control periods. Most studies were short-term with a median (interquartile range) follow-up of 3 (3, 8.5) weeks. Two were of a single HD session, and two of a single week's HD. Half of the studies were conducted prior to 2000, and five reported use of obsolete HD practices. Risks of bias in the included studies were often high or unclear, lowering confidence in the results.Compared to neutral or high dialysate [Na+], low dialysate [Na+] had the following effects on "efficacy" endpoints: reduced interdialytic weight gain (10 studies: MD -0.35 kg, 95% CI -0.18 to -0.51; high certainty evidence); probably reduced predialysis mean arterial blood pressure (BP) (4 studies: MD -3.58 mmHg, 95% CI -5.46 to -1.69; moderate certainty evidence); probably reduced postdialysis mean arterial BP (MAP) (4 studies: MD -3.26 mmHg, 95% CI -1.70 to -4.82; moderate certainty evidence); probably reduced predialysis serum [Na+] (7 studies: MD -1.69 mM, 95% CI -2.36 to -1.02; moderate certainty evidence); may have reduced antihypertensive medication (2 studies: SMD -0.67 SD, 95% CI -1.07 to -0.28; low certainty evidence). Compared to neutral or high dialysate [Na+], low dialysate [Na+] had the following effects on "safety" endpoints: probably increased intradialytic hypotension events (9 studies: RR 1.56, 95% 1.17 to 2.07; moderate certainty evidence); probably increased intradialytic cramps (6 studies: RR 1.77, 95% 1.15 to 2.73; moderate certainty evidence).Compared to neutral or high dialysate [Na+], low dialysate [Na+] may make little or no difference to: intradialytic BP (2 studies: MD for systolic BP -3.99 mmHg, 95% CI -17.96 to 9.99; diastolic BP 1.33 mmHg, 95% CI -6.29 to 8.95; low certainty evidence); interdialytic BP (2 studies:, MD for systolic BP 0.17 mmHg, 95% CI -5.42 to 5.08; diastolic BP -2.00 mmHg, 95% CI -4.84 to 0.84; low certainty evidence); dietary salt intake (2 studies: MD -0.21g/d, 95% CI -0.48 to 0.06; low certainty evidence).Due to very low quality of evidence, it is uncertain whether low dialysate [Na+] changed extracellular fluid status, venous tone, arterial vascular resistance, left ventricular mass or volumes, thirst or fatigue. Studies did not examine cardiovascular or all-cause mortality, cardiovascular events, or hospitalisation. It is likely that low dialysate [Na+] reduces intradialytic weight gain and BP, which are effects directionally associated with improved outcomes. However, the intervention probably also increases intradialytic hypotension and reduces serum [Na+], effects that are associated with increased mortality risk. The effect of the intervention on overall patient health and well-being is unknown. Further evidence is needed in the form of longer-term studies in contemporary settings, evaluating end-organ effects in small-scale mechanistic studies using optimal methods, and clinical outcomes in large-scale multicentre RCTs.

Anti-VEGF drugs are effective at improving vision in people with DMO with three to four in every 10 people likely to experience an improvement of 3 or more lines VA at one year. Aflibercept may confer some advantage over ranibizumab and bevacizumab in people with DMO at one year in visual and anatomic terms but it is unclear whether this applies to the long-term. There is a need for more evidence on the long-term (greater than two years) comparative effects of these anti-VEGF agents. Evidence from RCTs may not apply to real-world practice, where people in need of antiangiogenic treatment are often under-treated and under-monitored.We found no signals of differences in overall safety between the three antiangiogenic drugs that are currently available to treat DMO, but our estimates are imprecise for cardiovascular events and death.

This is an update of a previously published version of the review (Issue 10, 2011).Epithelial ovarian cancer (EOC) is the seventh most common cause of cancer death among women worldwide. Treatment consists of a combination of surgical debulking and platinum-based chemotherapy. Between 55% and 75% of women who respond to first-line therapy experience relapse within twoyears. Second-line chemotherapy is palliative and aims to reduce symptoms and prolong survival. Improved understanding about the molecular basis of EOC has led to the development of novel agents, such as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors and anti-EGFR antibodies. To compare the effectiveness and harmful effects of interventions that target the epidermal growth factor receptor in the treatment of epithelial ovarian cancer (EOC). We searched the Cochrane Gynaecological Cancer Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL; 2010, Issue 4), MEDLINE, and Embase up to October 2010. We also searched registers of clinical trials, abstracts of scientific meetings, and reference lists of included studies, and we contacted experts in the field. This update includes further searches up to September 2017. Randomised controlled trials (RCTs) comparing anti-EGFR agents with or without conventional chemotherapy versus conventional chemotherapy alone or no treatment in women with histologically proven EOC. Two review authors independently abstracted data, assessed risk of bias, and performed GRADE assessment. From 6105 references obtained through the literature search and an additional 15 references derived from grey literature searches, we identified seven RCTs that met our inclusion criteria and included 1725 participants. Trial results show that after first-line chemotherapy is provided, maintenance treatment with erlotinib (EGFR tyrosine kinase inhibitor (TKI)) probably makes little or no difference in overall survival (hazard ratio (HR) 0.99, 95% confidence interval (CI) 0.81 to 1.20; one study; 835 participants; low-certainty evidence) and may make little or no difference in progression-free survival (HR 1.05, 95% CI 0.90 to 1.23; one study; 835 participants; very low-certainty evidence). Less than 50% of participants provided quality of life data, and study authors reported these results incompletely. The certainty of evidence is very low, but treatment may reduce quality of life compared to observation.Treatment with an EGFR TKI (vandetanib) for women with relapsed EOC may make little or no difference in overall survival (HR 1.25, 95% CI 0.80 to 1.95; one study; 129 participants; low-certainty evidence) and may make little or no difference in progression-free survival (HR 0.99, 95% CI 0.69 to 1.42; one study; 129 participants; very low-certainty evidence). In treating patients with relapse, giving EGFR TKI may slightly increase some toxicities, such as severe rash (risk ratio (RR) 13.63, 95% CI 0.78 to 236.87; one study; 125 participants; very low-certainty evidence). Quality of life data were not available for meta-analysis.Anti-EGFR antibody treatment in relapsed EOC may or may not make a difference to overall survival (HR 0.93, 95% CI 0.74 to 1.18; four studies; 658 participants; moderate-certainty evidence) and may or may not have any effect on progression-free survival (HR 0.90, 95% CI 0.70 to 1.16; four studies; 658 participants; low-certainty evidence). Anti-EGFR antibody treatment may or may not increase side effects, including severe nausea and/or vomiting (RR 1.27, 95% CI 0.56 to 2.89; three studies; 503 participants; low-certainty evidence), severe fatigue (RR 1.06, 95% CI 0.66 to 1.73; I² = 0%; four studies; 652 participants; low-certainty evidence), and hypokalaemia (RR 2.01, 95% CI 0.80 to 5.06; I² = 0%; three studies; 522 participants; low-certainty evidence). Severe diarrhoea rates were heterogeneous across studies (RR 2.87, 95% CI 0.59 to 13.89; four studies; 652 participants; low-certainty evidence), and subgroup analysis revealed that severe diarrhoea was more likely with pertuzumab (RR 6.37, 95% CI 1.89 to 21.45; I² = 0%; three studies; 432 participants; low-certainty evidence) than with seribantumab treatment (RR 0.38, 95% CI 0.07 to 2.23; I² = 0%; one study; 220 participants; very low-certainty evidence). Quality of life data were incompletely reported, and we were unable to combine them in a meta-analysis. Current evidence suggests that an anti-EGFR single-agent biological treatment (EGFR TKI or anti-EGFR antibody) makes little or no difference to survival, either as maintenance treatment after first-line chemotherapy or in association with chemotherapy in recurrent cancer. Anti-EGFR therapy may increase some side effects and may or may not reduce quality of life.

In preterm infants less than 36 weeks' PMA, rescue S-LMA may have little or no effect on the composite outcome of death or BPD at 36 weeks' PMA. However, it may reduce the need for mechanical ventilation at any time. This benefit is limited to trials reporting the use of analgesia or sedation in the InSurE and S-ETT groups. There is low- to very-low certainty evidence for no or little difference in neonatal morbidities and mortality. Long-term outcomes are largely unreported. In preterm infants less than 32 weeks' PMA or less than 1500 g, there are insufficient data to support or refute the use of S-LMA in clinical practice. Adequately powered trials are required to determine the effect of S-LMA for prevention or early treatment of RDS in extremely preterm infants. S-LMA use should be limited to clinical trials in this group of infants.
