From epidemiological studies and studies done evaluating microbiomes in infants, there is a strong signal that the infants born by elective cesarean section (C-section) develop microbiota that differs from those babies born by vaginal delivery. Epidemiological studies show increased odds ratios for the development of immunological disorders such as type 1 diabetes, celiac disease, asthma, allergic diseases as well as metabolic diseases such as obesity in babies born by C-section. These are interesting associations, and if supported by additional studies that rigorously control for confounding factors, they will have major public health implications...

REVIEW
Alberto Monje, Andres Catena, Wenche S Borgnakke
AIM: This systematic review investigates whether hyperglycemia/diabetes mellitus is associated with peri-implant diseases (peri-implant mucositis and peri-implantitis). MATERIALS AND METHODS: Electronic and manual literature searching was conducted. An a priori case definition for peri-implantitis was used as an inclusion criterion to minimize risk of bias. The Newcastle Ottawa Scale was used for quality assessment; random effect models were applied; and results were reported according to the PRISMA Statement...

Stable isotope analysis of primate tissues in tropical forest contexts is an increasingly popular means of obtaining information about niche distinctions among sympatric species, including preferences in feeding height, forest canopy density, plant parts, and trophism. However, issues of equifinality mean that feeding height, canopy density, as well as the plant parts and plant species consumed, may produce similar or confounding effects. With a few exceptions, researchers have so far relied largely on general principles and/or limited plant data from the study area as references for deducing the predominant drivers of primate isotope variation...

Autologous NP cell implantation is a potential therapeutic avenue for intervertebral disc (IVD) degeneration. However, monolayer expansion of cells isolated from surgical samples may negatively impact matrix production by way of dedifferentiation. Previously, we have used a continuous expansion culture system to successfully preserve a chondrocyte phenotype. In this work, we hypothesised that continuous expansion culture could also preserve nucleus pulposus (NP) phenotype. We confirmed that serial passaging drove NP dedifferentiation by significantly decreasing collagen type II, aggrecan and chondroadherin (CHAD) gene expression, compared to freshly isolated cells...

The treatment of epistaxis is well codified, ligation of the ethmoidal arteries being the last resort. We report the case of a 25-year-old pregnant patient, who has had a ligation of the anterior and posterior ethmoidal arteries after a persistent epistaxis. Postoperatively, she presented a complete ptosis and an impaired eye elevation without any visual acuity disorders, evoking a lesion of the upper branch of the common oculomotor nerve (third cranial nerve). The patient totally recovered after 3 months...

A spectral processing method was developed and tested for analyzing temperature-dependent attenuated total reflection infrared (ATR-IR) spectra of aliphatic polyesters. Spectra of a bio-based, biodegradable polymer, 3.9 mol % 3HHx poly[(R)-3-hydroxybutyrate- co-(R)-3-hydroxyhexanoate] (PHBHx), were analyzed and corrected prior to analysis using two-dimensional correlation spectroscopy (2D-COS). Removal of the temperature variation of diamond absorbance, correction of the baseline, ATR correction, and appropriate normalization were key to generating more reliable data...

Ming Yang, Ziwen He, Suhua Shi, Chung-I Wu
The allopatric model, which requires a period of geographical isolation for speciation to complete, has been the standard model in the modern era. Recently, "speciation with gene flow" has been widely discussed in relation to the model of "strict allopatry" and the level of DNA divergence across genomic regions. We wish to caution that genomic data by themselves may only permit the rejection of the simplest form of allopatry. Even a slightly more complex and realistic model that starts with sub-divided populations would be impossible to reject by the genomic data alone...

In recent past, direct-acting anti-viral drugs (DAAs) have become the standard of care for the treatment of hepatitis C virus (HCV) infection. However, the experience with the use of these drugs in Indian renal transplant recipients is limited. We retrospectively reviewed our experience with DAA-based treatment for HCV infection in such patients. Between April 2015 and December 2016, six adults (median age 41 [range 34-52] years, male 5; GT1 2, GT3 3, and GT4 1; including three with prior failed interferon-based treatment) had received genotype-guided, DAA-based anti-HCV treatment 1 to 158 (median 15) months after renal transplantation...

Our understanding of the frequency and duration of maternal care behaviours in the domestic dog during the first two postnatal weeks is limited, largely due to the inconsistencies in the sampling methodologies that have been employed. In order to develop a more concise picture of maternal care behaviour during this period, and to help establish the sampling method that represents these behaviours best, we compared a variety of time sampling methods Six litters were continuously observed for a total of 96hours over postnatal days 3, 6, 9 and 12 (24hours per day)...

PURPOSE: To evaluate the effect of isolated anterior cruciate ligament (ACL) injury on tibial external rotation as measured by the dial test. METHODS: Twenty-seven consecutive patients scheduled to undergo a primary ACL reconstruction were prospectively evaluated. Physical examination and magnetic resonance imaging findings were analyzed to exclude multiligamentous injury. The dial test was performed with the patient under anesthesia with a goniometer on both the affected and unaffected knees at 30° and 90°...

We evaluated the effect of hydrochlorothiazide in a sample of anuric patients on hemodialysis and found an increase in serum calcium, which occurred only in those with parathyroid hormone >300 pg/ml. This finding highlights the extra-renal effect of this diuretic and a possible role of parathyroid hormone in the mechanism. PURPOSE: Thiazide diuretics are commonly used in patients with chronic kidney disease to treat hypertension. Their effects on calcium and bone metabolism are not well established, once calciuria may not fully explain levels of calcium and parathyroid hormone (PTH) in this population...

The introduction of "highly sensitive" cardiac troponin assays (hsTn) has reinforced the evidence that only serial testing incorporated in running algorithms allows a more accurate diagnosis of acute myocardial infarction. In this report, we consider the available evidence supporting the use of fast track protocols for ruling out and ruling in non-ST elevation myocardial infarction (NSTEMI) and compare it with the content of recently released guideline by the European Society of Cardiology, noting some uncomfortable aspects that need urgent clarification and/or revision...
