This 2011 review predates current reporting standards and methodological expectations for Cochrane Reviews. It should not be used for clinical decision‐making. ⋯ Chemical and physical methods aimed at reducing exposure to house dust mite allergens cannot be recommended. It is doubtful whether further studies, similar to the ones in our review, are worthwhile. If other types of studies are considered, they should be methodologically rigorous and use other methods than those used so far, with careful monitoring of mite exposure and relevant clinical outcomes.

Review Meta AnalysisDipeptidyl peptidase-4 (DPP-4) inhibitors for type 2 diabetes mellitus.
In type 2 diabetes mellitus there is a progressive loss of beta-cell function. One new approach yielding promising results is the use of the orally active dipeptidyl peptidase-4 (DPP-4) inhibitors like sitagliptin and vildagliptin. ⋯ DPP-4 inhibitors have some theoretical advantages over existing therapies with oral antidiabetic compounds but should currently be restricted to individual patients. Long-term data especially on cardiovascular outcomes and safety are urgently needed before widespread use of these new agents. More information on the benefit-risk ratio of DPP-4 inhibitor treatment is necessary especially analysing adverse effects on parameters of immune function. Also, long-term data are needed investigating patient-oriented parameters like health-related quality of life, diabetic complications and all-cause mortality.

ReviewWITHDRAWN: Amino acids for amyotrophic lateral sclerosis / motor neuron disease.
Amyotrophic lateral sclerosis, also known as motor neuron disease, is a progressive neuromuscular disease that causes disability and eventual death. Various amino acid preparations, the three branched-chain amino acids (L-leucine, L-valine and L-isoleucine) or, alternatively, L-threonine have been used as experimental therapy. ⋯ There is no evidence to support a beneficial effect of either branched-chain amino acids or L-threonine in amyotrophic lateral sclerosis/motor neuron disease.

Review Meta AnalysisLong-term results of laparoscopic colorectal cancer resection.
Although minimally invasive surgery has been accepted for a variety of disorders, laparoscopic resection of colorectal cancer is performed by few. Concern about oncological radicality and long term outcome has limited the adoption of laparoscopic surgery for colorectal cancer. ⋯ Laparoscopic resection of carcinoma of the colon is associated with a long term outcome no different from that of open colectomy. Further studies are required to determine whether the incidence of incisional hernias and adhesions is affected by method of approach. Laparoscopic surgery for cancer of the upper rectum is feasible, but more randomised trials need to be conducted to assess long term outcome.

Review Meta AnalysisChinese herbal medicine Huangqi type formulations for nephrotic syndrome.
At present, there is a lack of safe and effective drugs for nephrotic syndrome (NS). Huangqi type formulations have been used to treat nephrotic syndrome for years in China, however the effects and safety of these formulations have not been systematically reviewed. ⋯ Huangqi type formulations may have some positive effects in treating NS by increasing plasma albumin and reducing blood cholesterol, Cushing's syndrome, hormone reduced syndrome and respiratory tract infection. However, limited by the lack of high quality clinical studies, we are unable to recommend Huangqi type formulations for NS. Large, properly randomised, placebo-controlled, double-blind studies are required.
