Meta AnalysisPresent-centered therapy (PCT) for post-traumatic stress disorder (PTSD) in adults.
Present-centered therapy (PCT) is a non-trauma, manualized psychotherapy for adults with post-traumatic stress disorder (PTSD). PCT was originally designed as a treatment comparator in trials evaluating the effectiveness of trauma-focused cognitive-behavioral therapy (TF-CBT). Recent trials have indicated that PCT may be an effective treatment option for PTSD and that patients may drop out of PCT at lower rates relative to TF-CBT. ⋯ Moderate-quality evidence indicates that PCT is more effective in reducing PTSD severity compared to control conditions. Low quality of evidence did not support PCT as a non-inferior treatment compared to TF-CBT on clinician-rated post-treatment PTSD severity. The treatment effect differences between PCT and TF-CBT may attenuate over time. PCT participants drop out of treatment at lower rates relative to TF-CBT participants. Of note, all of the included studies were primarily designed to test the effectiveness of TF-CBT which may bias results away from PCT non-inferiority.The current systematic review provides the most rigorous evaluation to date to determine whether PCT is comparably as effective as TF-CBT. Findings are generally consistent with current clinical practice guidelines that suggest that PCT may be offered as a treatment for PTSD when TF-CBT is not available.

Meta AnalysisWorkplace interventions for increasing standing or walking for decreasing musculoskeletal symptoms in sedentary workers.
The prevalence of musculoskeletal symptoms among sedentary workers is high. Interventions that promote occupational standing or walking have been found to reduce occupational sedentary time, but it is unclear whether these interventions ameliorate musculoskeletal symptoms in sedentary workers. ⋯ Currently available limited evidence does not show that interventions to increase standing or walking in the workplace reduced musculoskeletal symptoms among sedentary workers at short-, medium-, or long-term follow up. The quality of evidence is low or very low, largely due to study design and small sample sizes. Although the results of this review are not statistically significant, some interventions targeting the physical work environment are suggestive of an intervention effect. Therefore, in the future, larger cluster-RCTs recruiting participants with baseline musculoskeletal symptoms and long-term outcomes are needed to determine whether interventions to increase standing or walking can reduce musculoskeletal symptoms among sedentary workers and can be sustained over time.

Meta AnalysisFluorides for preventing early tooth decay (demineralised lesions) during fixed brace treatment.
Early dental decay or demineralised lesions (DLs, also known as white spot lesions) can appear on teeth during fixed orthodontic (brace) treatment. Fluoride reduces decay in susceptible individuals, including orthodontic patients. This review compared various forms of topical fluoride to prevent the development of DLs during orthodontic treatment. This is the second update of the Cochrane Review first published in 2004 and previously updated in 2013. ⋯ This review found a low level of certainty that 12,300 ppm F foam applied by a professional every 6 to 8 weeks throughout fixed orthodontic treatment, might be effective in reducing the proportion of orthodontic patients with new DLs. In addition, there is a low level of certainty that the patient use of a high fluoride toothpaste (5000 ppm F) throughout orthodontic treatment, might be more effective than a conventional fluoride toothpaste. These two comparisons were based on single studies. There was insufficient evidence of a difference regarding the professional application of fluoride varnish (7700 or 10,000 ppm F). Further adequately powered, randomised controlled trials are required to increase the certainty of these findings and to determine the best means of preventing DLs in patients undergoing fixed orthodontic treatment. The most accurate means of assessing adherence with the use of fluoride products by patients and any possible adverse effects also need to be considered. Future studies should follow up participants beyond the end of orthodontic treatment to determine the effect of DLs on patient satisfaction with treatment.

Meta AnalysisPharmacological interventions for painful sickle cell vaso-occlusive crises in adults.
Sickle cell disease (SCD) is a group of inherited disorders of haemoglobin (Hb) structure in a person who has inherited two mutant globin genes (one from each parent), at least one of which is always the sickle mutation. It is estimated that between 5% and 7% of the world's population are carriers of the mutant Hb gene, and SCD is the most commonly inherited blood disorder. SCD is characterized by distorted sickle-shaped red blood cells. Manifestations of the disease are attributed to either haemolysis (premature red cell destruction) or vaso-occlusion (obstruction of blood flow, the most common manifestation). Shortened lifespans are attributable to serious comorbidities associated with the disease, including renal failure, acute cholecystitis, pulmonary hypertension, aplastic crisis, pulmonary embolus, stroke, acute chest syndrome, and sepsis. Vaso-occlusion can lead to an acute, painful crisis (sickle cell crisis, vaso-occlusive crisis (VOC) or vaso-occlusive episode). Pain is most often reported in the joints, extremities, back or chest, but it can occur anywhere and can last for several days or weeks. The bone and muscle pain experienced during a sickle cell crisis is both acute and recurrent. Key pharmacological treatments for VOC include opioid analgesics, non-opioid analgesics, and combinations of drugs. Non-pharmacological approaches, such as relaxation, hypnosis, heat, ice and acupuncture, have been used in conjunction to rehydrating the patient and reduce the sickling process. ⋯ This review identified only nine studies, with insufficient data for all pharmacological interventions for analysis. The available evidence is very uncertain regarding the efficacy or harm from pharmacological interventions used to treat pain related to sickle cell VOC in adults. This area could benefit most from more high quality, certain evidence, as well as the establishment of suitable registries which record interventions and outcomes for this group of people.

Meta AnalysisAdalimumab for induction of remission in Crohn's disease.
Adalimumab is an IgG1 monoclonal antibody that targets and blocks tumor necrosis factor-alpha, a pro-inflammatory cytokine involved in the pathogenesis of Crohn's disease (CD). A significant proportion of people with CD fail conventional therapy or therapy with biologics or develop significant adverse events. Adalimumab may be an effective alternative for these individuals. ⋯ High-certainty evidence suggests that adalimumab is superior to placebo for induction of clinical remission and clinical response in people with moderate to severely active CD. Although the rates of AEs, SAEs and withdrawals due to AEs were lower in adalimumab participants compared to placebo, we are uncertain about the effect of adalimumab on AEs due to the low number of events. Therefore, no firm conclusions can be drawn regarding the safety of adalimumab in CD. Futher studies are required to look at the long-term effectiveness and safety of using adalimumab in participants with CD.
