ReviewCrisis interventions for adults with borderline personality disorder.
People diagnosed with borderline personality disorder (BPD) frequently present to healthcare services in crisis, often with suicidal thoughts or actions. Despite this, little is known about what constitutes effective management of acute crises in this population and what type of interventions are helpful at times of crisis. In this review, we will examine the efficacy of crisis interventions, defined as an immediate response by one or more individuals to the acute distress experienced by another individual, designed to ensure safety and recovery and lasting no longer than one month. This review is an update of a previous Cochrane Review examining the evidence for the effects of crisis interventions in adults diagnosed with BPD. ⋯ A comprehensive search of the literature revealed very little RCT-based evidence to inform the management of acute crises in people diagnosed with BPD. We included two studies of two very different types of intervention (JCP and BA). We found no clear evidence of a benefit over TAU in any of our main outcomes. We are very uncertain about the true effects of either intervention, as the evidence was judged low- and very low-certainty, and there was only a single study of each intervention. There is an urgent need for high-quality, large-scale, adequately powered RCTs on crisis interventions for people diagnosed with BPD, in addition to development of new crisis interventions.

Review Meta AnalysisAcupuncture for treating overactive bladder in adults.
Overactive bladder is a common, long-term symptom complex, which includes frequency of micturition, urgency with or without associated incontinence and nocturia. Around 11% of the population have symptoms, with this figure increasing with age. Symptoms can be linked to social anxiety and adaptive behavioural change. The cost of treating overactive bladder is considerable, with current treatments varying in effectiveness and being associated with side effects. Acupuncture has been suggested as an alternative treatment. ⋯ The evidence is very uncertain about the effect acupuncture has on cure or improvement of overactive bladder symptoms compared to no treatment. It is uncertain if there is any difference between acupuncture and sham acupuncture in cure or improvement of overactive bladder symptoms. This review provides low-certainty evidence that acupuncture may result in a slight increase in cure or improvement of overactive bladder symptoms when compared with medication and may reduce the incidence of minor adverse events. These conclusions must remain tentative until the completion of larger, higher-quality studies that use relevant, comparable outcomes. Timing and frequency of treatment, point selection, application and long-term follow-up are other areas relevant for research.

Review Meta AnalysisAppetite stimulants for people with cystic fibrosis.
Chronic loss of appetite in cystic fibrosis concerns both individuals and families. Appetite stimulants have been used to help cystic fibrosis patients with chronic anorexia attain optimal body mass index (BMI) and nutritional status. However, these may have adverse effects on clinical status. This is an updated version of the original review. ⋯ We included four trials (70 participants) comparing appetite stimulants (cyproheptadine hydrochloride and megestrol acetate) to placebo; the numbers of adults or children within each trial were not always reported. We assessed the certainty of evidence as low due to the small number of participants, incomplete or selective outcome reporting, and unclear risk of selection bias. Regarding our primary outcomes, a meta-analysis of two trials (42 participants) showed that appetite stimulants may produce a larger increase in weight (kg) at three months (mean difference (MD) 1.25 kg, 95% confidence interval (Cl) 0.45 to 2.05), and one trial (17 participants) showed a similar result at six months (MD 3.80 kg, 95% CI 1.27 to 6.33) (both low-certainty evidence). Results also showed that weight z score may increase with appetite stimulants compared to placebo at three months (MD 0.61, 95% CI 0.29 to 0.93; 3 studies; 40 participants; P < 0.001) and at six months (MD 0.74, 95% CI 0.26 to 1.22; 1 trial; 17 participants). There was no evidence of a difference in effect between cyproheptadine hydrochloride and megestrol acetate for either outcome. Only one trial (25 participants) reported analysable data for body composition (BMI), with results favouring cyproheptadine hydrochloride compared to placebo; a further trial (16 participants) narratively agreed with this result. All four trials reported on lung function at durations ranging from two to nine months. Considering analysable data, two trials (42 participants) found that appetite stimulants may make little or no difference in forced expiratory volume at one second (FEV1) % predicted at three months, and one trial (17 participants) found similar results at six months. Two further three-month trials narratively agreed with these results. Limited information was reported for secondary outcomes. Two trials (23 participants) reported results showing that appetite stimulants may increase appetite compared to placebo at three months (odds ratio 45.25, 95% CI 3.57 to 573.33; low-certainty evidence). Only one study reported on quality of life, finding that cyproheptadine reduced fatigue in two participants compared with none with placebo. One study (25 participants) found no difference in energy intake between appetite stimulant or placebo at three months. Insufficient reporting of adverse effects prevented a full determination of their impact. Two studies (33 participants) narratively reported similar requirements for additional antibiotics between appetite stimulants and placebo at three months. AUTHORS' CONCLUSIONS: At six months in adults and children, appetite stimulants improved only two of the outcomes of this review: weight (or weight z score) and subjectively reported appetite. Insufficient reporting of side effects prevented a full determination of their impact. Whilst the data may suggest the potential use of appetite stimulants in treating anorexia in adults and children with cystic fibrosis, this is based upon low-certainty evidence from a small number of trials, therefore firm conclusions cannot be drawn. Clinicians need to be aware of the potential adverse effects of appetite stimulants and actively monitor any individuals prescribed these medications accordingly. Research is required to determine meaningful surrogate measures for appetite and to define what constitutes quality weight gain. Future trials of appetite stimulants should use a validated measure of symptoms including a disease-specific instrument for measuring poor appetite. This review highlights the need for multicentred, adequately powered, and well-designed trials to evaluate agents to safely increase appetite in people with cystic fibrosis and to establish the optimal mode of treatment.

ReviewPharmacological interventions for the treatment of disordered and problem gambling.
Pharmacological interventions for disordered and problem gambling have been employed in clinical practice. Despite the availability of several reviews of the efficacy of pharmacological interventions for disordered or problem gambling, few have employed systematic search strategies or compared different categories of pharmacological interventions. Systematic reviews of high-quality evidence are therefore essential to provide guidance regarding the efficacy of different pharmacological interventions for disordered or problem gambling. ⋯ This review provides preliminary support for the use of opioid antagonists (naltrexone, nalmefene) and atypical antipsychotics (olanzapine) to produce short-term improvements in gambling symptom severity, although a lack of available evidence precludes a conclusion regarding the degree to which these pharmacological agents can improve other gambling or psychological functioning indices. In contrast, the findings are inconclusive with regard to the effects of mood stabilisers (including anticonvulsants) in the treatment of disordered or problem gambling, and there is limited evidence to support the efficacy of antidepressants. However, these conclusions are based on very low to low certainty evidence characterised by a small number of included studies, high risk of bias, modest pooled sample sizes, imprecise estimates, moderate between-study heterogeneity, and exclusion of participants with psychiatric comorbidities. Moreover, there were insufficient studies to conduct meta-analyses on many outcome measures; to compare efficacy across and within major categories of interventions; to explore dosage effects; or to examine effects beyond post-treatment. These limitations suggest that, despite recommendations related to the administration of opioid antagonists in the treatment of disordered or problem gambling, pharmacological interventions should be administered with caution and with careful consideration of patient needs. A larger and more methodologically rigorous evidence base with longer-term evaluation periods is required before definitive conclusions can be drawn about the effectiveness and durability of pharmacological treatments for disordered or problem gambling.

ReviewNirmatrelvir combined with ritonavir for preventing and treating COVID-19.
Oral nirmatrelvir/ritonavir (Paxlovid®) aims to avoid severe COVID-19 in asymptomatic people or those with mild symptoms, thereby decreasing hospitalization and death. Due to its novelty, there are currently few published study results. It remains to be evaluated for which indications and patient populations the drug is suitable. OBJECTIVES: To assess the efficacy and safety of nirmatrelvir/ritonavir (Paxlovid®) plus standard of care compared to standard of care with or without placebo, or any other intervention for treating COVID-19 and for preventing SARS-CoV-2 infection. To explore equity aspects in subgroup analyses. To keep up to date with the evolving evidence base using a living systematic review (LSR) approach and make new relevant studies available to readers in-between publication of review updates. ⋯ There is low-certainty evidence that nirmatrelvir/ritonavir reduces the risk of all-cause mortality and hospital admission or death based on one trial investigating unvaccinated COVID-19 participants without previous infection that were at high risk and with symptom onset of no more than five days. There is low- to moderate-certainty evidence that nirmatrelvir/ritonavir is safe in people without prior or concomitant therapies including medications highly dependent on CYP3A4. Regarding equity aspects, except for ethnicity, no differences in effect size and direction were identified. No evidence is available on nirmatrelvir/ritonavir to treat hospitalized people with COVID-19 and to prevent a SARS-CoV-2 infection. We will continually update our search and make search results available on OSF.
