Overt thyroid disease, be it overt hypothyroidism or overt hyperthyroidism, is associated with a multitude of adverse outcomes during pregnancy including miscarriage, gestational hypertension, gestational diabetes, preterm delivery and decreased IQ in the offspring.1 In its most severe form, overt hypothyroidism results in cretinism. The impact of subclinical hypothyroidism (SCH) on pregnancy outcomes is complex. Observational and retrospective studies have shown a correlation with adverse maternal and fetal events.2 In 1999, Pop et al 3 and Haddow et al 4 reported a correlation between hypothyroidism and isolated hypothyroxinaemia (IH) with decreased neurocognitive function in the offspring. However, only two prospective randomised studies have evaluated the impact of levothyroxine therapy for SCH or IH on pregnancy outcomes. In an Italian study, levothyroxine therapy for SCH in thyroid antibody-positive women in the first trimester of pregnancy …

Our goal was to determine the extent to which recommendations for primary care practice are informed by high-quality research-based evidence, and the extent to which they are based on evidence of improved health outcomes (patient-oriented evidence). As a substrate for study, we used Essential Evidence, an online, evidence-based, medical reference for generalists. Each of the 721 chapters makes overall recommendations for practice that are graded A, B or C using the Strength of Recommendations Taxonomy (SORT). SORT A represents consistent and good quality patient-oriented evidence; SORT B is inconsistent or limited quality patient-oriented evidence and SORT C is expert opinion, usual practice or recommendations relying on surrogate or intermediate outcomes. Pairs of researchers abstracted the evidence ratings for each chapter in tandem, with discrepancies resolved by the lead author. Of 3251 overall recommendations, 18% were graded 'A', 34% were 'B' and 49% were 'C'. Clinical categories with the most 'A' recommendations were pregnancy and childbirth, cardiovascular, and psychiatric; those with the least were haematological, musculoskeletal and rheumatological, and poisoning and toxicity. 'A' level recommendations were most common for therapy and least common for diagnosis. Only 51% of recommendations are based on studies reporting patient-oriented outcomes, such as morbidity, mortality, quality of life or symptom reduction. In conclusion, approximately half of the recommendations for primary care practice are based on patient-oriented evidence, but only 18% are based on patient-oriented evidence from consistent, high-quality studies.

In children, complicated pneumonia implies pneumonia infection that is associated with pleural effusion or empyema.1 Initial management involves use of parenteral broad spectrum antibiotics to cover the most common organisms1; thoracotomy or chest tube insertion may be indicated if there is no response to antibiotic therapy, or if there is significant respiratory difficulty. Most national guidelines do not specify the preferred route of antibiotic therapy for postdischarge treatment. For instance, British guidelines recommend a switch to oral antibiotics if there is clear evidence of improvement,2 while American guidelines are non-specific.3 This retrospective study compared the benefits and harms of intravenous versus oral antibiotic therapy for treatment of complicated pneumonia in children postdischarge.

Commentary on : Yuan C, Gaskins AJ, Blaine AI, et al . Association between cesarean birth and risk of obesity in offspring in childhood, adolescence, and early adulthood. JAMA Pediatr 2016;170:e162385. Since 2008, several observational studies have reported an association between caesarean section (CS) and offspring obesity. The underlying biological mechanism hypothesised to explain this association is that children born via CS lack exposure to the maternal vaginal flora, resulting in colonisation of the gut with flora that increase energy harvesting from food, thereby contributing to the development of obesity. Maternal pre-pregnancy weight confounds this association, as obesity in the mother is associated with CS and offspring obesity. Not all previous studies were able to adjust for maternal pre-pregnancy weight, but a recent systematic review showed that in studies that were able to adjust for this confounder, there remained a statistically significant …

Lancet 2016;388:1903–11. The role of coronary arteriography in patients with non-ST segment elevation acute coronary syndrome is controversial. Many cardiologists advocate a ‘routine invasive strategy’, which comprises coronary arteriography within a few days of presentation and myocardial revascularisation determined by the angiographic findings, but this exposes patients to procedural risks and incurs significant costs. Other clinicians favour a ‘selective invasive strategy’, with coronary arteriography reserved for patients with recurrent myocardial ischaemia. Randomised trials of these treatment strategies suggest that a routine invasive strategy reduces the risk of recurrent ischaemia and death or recurrent myocardial infarction over 5 years.1 In the RITA-3 trial, a routine invasive strategy was also associated with lower cardiovascular …

Commentary on : Hamdy FC , Donovan JL , Lane JA , et al . 10-Year outcomes after monitoring, surgery, or radiotherapy for localized prostate cancer. N Engl J Med 2016;375:1415–24.[OpenUrl][1] Donovan JL, Hamdy FC, Lane JA, et al . Patient-reported outcomes after monitoring, surgery, or radiotherapy for prostate cancer. N Engl J Med 2016;375:1425–37. Prostate cancer (PCA) remains a common and potentially fatal condition. Effective and safe treatment options are needed. However, few randomised trials have assessed the benefits and harms of radical prostatectomy (RPX), radiation therapy (XRT) and watchful waiting/observation to provide the evidence base for treating men with clinically localised PCA. The Scandinavian Prostate Cancer Group-4 (SPCG-4) trial randomised 695 men diagnosed in the pre-prostate-specific antigen (PSA) era, most had palpable disease, to surgery or observation.1 After a median follow-up of 13.4 years, surgery reduced PCA deaths by 44% (HR=0.56; 95% CI 0.41 to 0.77; absolute risk reduction=11 percentage points). All-cause mortality was reduced by 12.7 percentage points. Reductions were confined to men <65 years of age. The Prostate Cancer Intervention Versus Observation Trial (PIVOT) randomised 731 men from the early PSA era to RPX or observation.2 After a 10-year median follow-up, surgery did not reduce disease-specific mortality (HR=0.63; 95% CI 0.36 to 1.09). There was also no significant reduction for all-cause mortality. Absolute differences were 10 ng/mL or intermediate risk disease (p for interaction=0.11 for PCA mortality in both subgroups).
