Review Meta AnalysisUncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer.
Choosing an optimal reconstruction method is pivotal for patients with gastric cancer undergoing distal gastrectomy. The uncut Roux-en-Y reconstruction, a variant of the conventional Roux-en-Y approach (or variant of the Billroth II reconstruction), employs uncut devices to occlude the afferent loop of the jejunum. This modification is designed to mitigate postgastrectomy syndrome and enhance long-term functional outcomes. However, the comparative benefits and potential harms of this approach compared to other reconstruction techniques remain a topic of debate. ⋯ Given the predominance of low- to very low-certainty evidence, this Cochrane review faces challenges in providing definitive clinical guidance. We found the majority of critical outcomes may be comparable between the uncut Roux-en-Y reconstruction and other methods, but we are very uncertain about most of these results. Nevertheless, it indicates that uncut Roux-en-Y reconstruction may reduce the incidence of bile reflux compared to Billroth-II reconstruction, albeit with low certainty. In contrast, compared to Roux-en-Y reconstruction, uncut Roux-en-Y may increase bile reflux incidence, based on very low-certainty evidence. To strengthen the evidence base, further rigorous and long-term trials are needed. Additionally, these studies should explore variations in surgical procedures, particularly regarding uncut devices and methods to prevent recanalisation. Future research may potentially alter the conclusions of this review.

Massage is widely used for neck pain, but its effectiveness remains unclear. ⋯ The contribution of massage to the management of neck pain remains uncertain given the predominance of low-certainty evidence in this field. For subacute and chronic neck pain (closest to 12 weeks follow-up), massage may result in a little or no difference in improving pain, function-disability, health-related quality of life and participant-reported treatment success when compared to a placebo. Inadequate reporting on adverse events precluded analysis. Focused planning for larger, adequately dosed, well-designed trials is needed.

Oral submucous fibrosis (OSF) is a chronic disease of the oral cavity that causes progressive constriction of the cheeks and mouth accompanied by severe pain and reduced mouth opening. OSF has a significant impact on eating and swallowing, affecting quality of life. There is an increased risk of oral malignancy in people with OSF. The main risk factor for OSF is areca nut chewing, and the mainstay of treatment has been behavioural interventions to support habit cessation. This review is an update of a version last published in 2008. ⋯ We found moderate-certainty evidence that antioxidants administered systemically probably improve mouth opening slightly at three to six months and improve burning sensation VAS scores up to and beyond six months. We found only low/very low-certainty evidence for all other comparisons and outcomes. There was insufficient evidence to make an informed judgement about potential adverse effects associated with any of these treatments. There was insufficient evidence to support or refute the effectiveness of the other interventions tested. High-quality, adequately powered intervention trials with a low risk of bias that compare biologically plausible treatments for OSF are needed. It is important that relevant participant-reported outcomes are evaluated.

ReviewTherapeutic exercises for idiopathic scoliosis in adolescents.
Adolescent idiopathic scoliosis (AIS) is a pathology that changes the three-dimensional shape of the spine and trunk. While AIS can progress during growth and cause cosmetic issues, it is usually asymptomatic. However, a final spinal curvature above the critical threshold of 30° increases the risk of health problems and curve progression in adulthood. The use of therapeutic exercises (TEs) to reduce the progression of AIS and delay or avoid other, more invasive treatments is still controversial. ⋯ The evidence on the efficacy of TE is currently sparse due to heterogeneity, small sample size, and many different comparisons. We found only one study following participants to the end of growth showing the efficacy of PSSE over TE. This result was weakened by adding studies with short-term results and unclear preparation of treating physiotherapists. More RCTs are needed to strengthen the current evidence and study other highly clinically relevant outcomes such as QoL, psychological and cosmetic issues, and back pain.

ReviewMacrolide antibiotics (including azithromycin) for cystic fibrosis.
Cystic fibrosis (CF) is a life-limiting genetic condition, affecting over 90,000 people worldwide. CF affects several organs in the body, but airway damage has the most profound impact on quality of life (QoL) and survival. Causes of lower airway infection in people with CF are, most notably, Staphylococcus aureus in the early course of the disease and Pseudomonas aeruginosa at a later stage. Macrolide antibiotics, e.g. azithromycin and clarithromycin, are usually taken orally, have a broad spectrum of action against gram-positive (e.g. S aureus) and some gram-negative bacteria (e.g. Haemophilus influenzae), and may have a modifying role in diseases involving airway infection and inflammation such as CF. They are well-tolerated and relatively inexpensive, but widespread use has resulted in the emergence of resistant bacteria. This is an updated review. ⋯ Azithromycin therapy is associated with a small but consistent improvement in respiratory function, a decreased risk of exacerbation and longer time to exacerbation at six months; but evidence for treatment efficacy beyond six months remains limited. Azithromycin appears to have a good safety profile (although a weekly dose was associated with more gastrointestinal side effects, which makes it less acceptable for long-term therapy), with a relatively minimal treatment burden for people with CF, and it is inexpensive. A wider concern may be the emergence of macrolide resistance reported in the most recent study which, combined with the lack of long-term data, means we do not feel that the current evidence is strong enough to support azithromycin therapy for all people with CF. Future research should report over longer time frames using validated tools and consistent reporting, to allow for easier synthesis of data. In particular, future trials should report important adverse events such as hearing impairment or liver disease. More data on the effects of azithromycin given in different ways and reporting on our primary outcomes would benefit decision-making on whether and how to give macrolide antibiotics. Finally, it is important to assess azithromycin therapy for people with CF who are established on the relatively new cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies which correct the underlying molecular defect associated with CF (none of the trials included in the review are relevant to this population).
