Type 2 diabetes mellitus is a complex and heterogeneous disorder which in its most common manifestation arises from insulin resistance and later insulin insufficiency. Type 2 diabetes is characterised by impaired insulin sensitivity and diagnosed as hyperglycaemia. Because of its cardiovascular consequences, Type 2 diabetes represents one of the world's leading causes of mortality and morbidity. Drug discovery and development are required to produce better ways to prevent, treat and manage diabetes and its complications...

BACKGROUND: A fish spike injury can be sustained by anyone handling fish; during fishing, meal preparation or in retail. Case reports of fish spikes inoculating victims with virulent marine-specific pathogens and causing systemic illness led us to question whether empirical treatment of these injuries with amoxicillin and clavulanic acid is adequate. METHODS: This 2-year prospective observational study was conducted at Middlemore Hospital, Auckland, New Zealand...

BACKGROUND: The main reason for morbidity after aneurysmal subarachnoid hemorrhage (aSAH) is delayed cerebral ischemia (DCI). The mainstay of medical therapy for treating DCI is induced hypertension with vasopressors to restore cerebral perfusion. Both phenylephrine (PE) and norepinephrine (NE) are commonly used for induced hypertension, but the impact of the initial choice of vasopressor on the efficacy, adverse effects, or outcome after hemodynamic therapy for DCI is unknown. METHODS: Sixty-three patients with aSAH between January 2012 and October 2014, who developed DCI (defined as new focal deficit or decline in Glasgow Coma Score) and in which PE (n = 45) or NE (n = 18) treatment was initiated were evaluated in this retrospective study...

Polycyclic aromatic hydrocarbons (PAHs) are widely spread in various ecosystems and are of great concern due to their potential toxicity, mutagenicity and carcinogenicity. Bioremediation has been proposed as an effective approach to remove PAHs. In this study, the physiological responses and proteome of Brevibacillus brevis under exposure to pyrene, a four-ring compound from PAHs family, were investigated. The changes of cell viability of B. brevis were observed during the degradation of pyrene by means of flow cytometry...

BACKGROUND: Postpartum depression (PPD) is prevalent, occurring in 8 to 13% of new fathers. Identifying effective and acceptable treatments for paternal PPD is important to prevent negative family outcomes. Participation in a patient preferred treatment for depression increases treatment adherence and effectiveness. Thus, developing and delivering interventions that are preferred by the target population is an important aspect of successful treatment. The current study investigated treatment preferences for paternal PPD...

Multiple sclerosis (MS) is a chronic inflammatory disease of the CNS, and one of the most common causes of disability in young adults. Over the last decade, new disease modifying therapies have rapidly emerged, including monoclonal antibodies (mAbs) that have provided highly targeted therapies with superior efficacy compared to platform therapies. In particular, monoclonal antibodies directed against CD20-positive B cells have shown remarkable results in recent clinical trials, and renewed interest in the mechanism of B-cell depleting therapies to ameliorate relapse activity and progression in MS...

As immune-related pathways involved in the pathogenesis of psoriasis are elucidated, new biologic treatments targeting these steps of the psoriatic immune cascade are developed. In this article, we review the literature on IL-23 and IL-17 inhibitors in the pipeline for use in moderate to severe psoriasis. Numerous pipeline biologic therapies, including risankizumab, guselkumab, tildrakizumab, ixekizumab, and brodalumab, are being investigated in phase 2 and 3 studies to establish the efficacy and safety of these new agents...

BACKGROUND: Sevoflurane is the most widely used inhalational anesthetic in pediatric medicine. Despite this, sevoflurane has been reported to exert potentially neurotoxic effects on the developing brain. Clinical interventions and treatments for these effects are limited. Tanshinone IIA (Tan IIA), extracted from Salvia miltiorrhiza (Danshen), has been documented to alleviate cognitive decline in traditional applications. Therefore, we hypothesized that preadministration of Tan IIA may attenuate sevoflurane-induced neurotoxicity, suggesting that Tan IIA is a new and promising drug capable of counteracting the effects of cognitive dysfunction produced by general anesthetics...

PURPOSE OF REVIEW: Benign prostatic enlargement is a common age-related condition, affecting over 50% of men aged more than 60 years. Side effects of medical therapy and significant morbidity of transurethral resection of the prostate and open surgery led to the development of so-called minimally invasive procedures, with the aim to be efficient but with less morbidity and shorter or no hospitalization. For this review, a systematic literature was performed. We report recent results in different treatment options for benign prostate hypoplasia (BPH) and recommend the best minimal-invasive treatment for BPH...

Toshiro Tango
Tango (Biostatistics 2016) proposed a new repeated measures design called the S:T repeated measures design, combined with generalized linear mixed-effects models and sample size calculations for a test of the average treatment effect that depend not only on the number of subjects but on the number of repeated measures before and after randomization per subject used for analysis. The main advantages of the proposed design combined with the generalized linear mixed-effects models are (1) it can easily handle missing data by applying the likelihood-based ignorable analyses under the missing at random assumption and (2) it may lead to a reduction in sample size compared with the simple pre-post design...

Primary central nervous system tumors are the most common solid neoplasm of childhood and the leading cause of cancer-related death in pediatric patients. Survival rates for children with malignant supratentorial brain tumors are poor despite aggressive treatment with combinations of surgery, radiation, and chemotherapy, and survivors often suffer from damaging lifelong sequelae from current therapies. Novel innovative treatments are greatly needed. One promising new approach is the use of a genetically engineered, conditionally replicating herpes simplex virus (HSV) that has shown tumor-specific tropism and potential efficacy in the treatment of malignant brain tumors...

Survivin is a member of the inhibitor of apoptosis (IAP) family. The function of the survivin protein is to inhibit caspase activation, thereby leading to negative regulation of apoptosis or programmed cell death. This has been shown by the disruption of survivin induction pathways leading to an increased apoptosis and decreased tumour growth. These data suggest that survivin may provide a new target for cancer treatment, which would distinguish transformed cells from normal cells. In the present study, we aimed to investigate exon 1 of the survivin gene by means of methylation-specific PCR and evaluate its impact on survivin protein expression following DNA isolation and bisulphite modification in paraffin-embedded normal and tumour tissues of lung cancer patients with squamous cell carcinoma...

17β-Hydroxysteroid dehydrogenase type 2 (17β-HSD2) converts the active steroid hormones estradiol, testosterone, and 5α-dihydrotestosterone into their weakly active forms estrone, Δ(4)-androstene-3,17-dione, and 5α-androstane-3,17-dione, respectively, thereby regulating cell- and tissue-specific steroid action. As reduced levels of active steroids are associated with compromised bone health and onset of osteoporosis, 17β-HSD2 is considered a target for antiosteoporotic treatment. In this study, a pharmacophore model based on 17β-HSD2 inhibitors was applied to a virtual screening of various databases containing natural products in order to discover new lead structures from nature...

Stem cell research arose from the need to explore new therapeutic possibilities for intractable and lethal diseases. Although musculoskeletal disorders are basically nonlethal, their high prevalence and relative ease of performing clinical trials have facilitated the clinical application of stem cells in this field. However, few reliable clinical studies have been published, despite the plethora of in vitro and preclinical studies in stem cell research for regenerative medicine in the musculoskeletal system...

Surgical resection of solid tumors is currently the gold standard and preferred therapeutic strategy for cancer. Chemotherapy drugs also make a significant contribution by inhibiting the rapid growth of tumor cells and these two approaches are often combined to enhance treatment efficacy. However, surgery and chemotherapy inevitably lead to severe side effects and high systemic toxicity, which in turn results in poor prognosis. Precision medicine has promoted the development of treatment modalities that are developed to specifically target and kill tumor cells...

Since their introduction, implant-retained overdentures have represented a feasible, economical, and highly successful treatment option for completely edentulous patients. Different attachment systems have been effectively used to retain these implant overdentures, and each system has advantages and disadvantages. Locator attachment (Zest Anchors) is one system that has been widely used by clinicians, particularly, for two-implant-supported situations. Recently, Zest Anchors developed a new locator-style abutment, Locator R-Tx...
