Jiří Černý, Bohdan Schneider, Lada Biedermannová
Water molecules represent an integral part of proteins and a key determinant of protein structure, dynamics and function. WatAA is a newly developed, web-based atlas of amino-acid hydration in proteins. The atlas provides information about the ordered first hydration shell of the most populated amino-acid conformers in proteins. The data presented in the atlas are drawn from two sources: experimental data and ab initio quantum-mechanics calculations. The experimental part is based on a data-mining study of a large set of high-resolution protein crystal structures...

REVIEW
Arunkumar E Achari, Sushil K Jain
Adiponectin is the most abundant peptide secreted by adipocytes, whose reduction plays a central role in obesity-related diseases, including insulin resistance/type 2 diabetes and cardiovascular disease. In addition to adipocytes, other cell types, such as skeletal and cardiac myocytes and endothelial cells, can also produce this adipocytokine. Adiponectin effects are mediated by adiponectin receptors, which occur as two isoforms (AdipoR1 and AdipoR2). Adiponectin has direct actions in liver, skeletal muscle, and the vasculature...

OBJECTIVE: Both trait and contextual self-concealment, as well as shame- and guilt-proneness, have previously been found to be associated with psychological distress. However, findings regarding the associations between these variables among patients with cancer and among the spouses of patients with cancer are limited. The aim of the current study was therefore to investigate the relationship between shame-proneness and psychological distress (anxiety and depression) by examining the mediating role of both trait and contextual self-concealment among patients with cancer and among the spouses of patients with cancer...

Inspiratory flow limitation (IFL) is a critical symptom of sleep breathing disorders. A characteristic flattened flow-time curve indicates the presence of highest resistance flow limitation. This study involved investigating a real-time algorithm for detecting IFL during sleep. Three categories of inspiratory flow shape were collected from previous studies for use as a development set. Of these, 16 cases were labeled as non-IFL and 78 as IFL which were further categorized into minor level (20 cases) and severe level (58 cases) of obstruction...

Currently we observe a gap between theory and practices of patient engagement. If both scholars and health practitioners do agree on the urgency to realize patient engagement, no shared guidelines exist so far to orient clinical practice. Despite a supportive policy context, progress to achieve greater patient engagement is patchy and slow and often concentrated at the level of policy regulation without dialoguing with practitioners from the clinical field as well as patients and families. Though individual clinicians, care teams and health organizations may be interested and deeply committed to engage patients and family members in the medical course, they may lack clarity about how to achieve this goal...

We have developed methods for full-genome sequencing of Zika viruses (ZIKVs) based on a targeted amplification approach. We used alignments of publicly available complete genome data to design a primer set that selectively amplifies ZIKVs. The approach includes amplification strategies for templates present at both high- and low-copy number, and PCR cycling conditions that have been normalized across genome fragments in order to streamline laboratory handling. Abundant templates can be amplified using a strategy that uses 6 overlapping amplicons to cover the complete viral genome, whereas scarce templates can be amplified using a strategy that uses 11 overlapping amplicons of smaller size...

Alberto Fernández, Cristobal José Carmona, María José Del Jesus, Francisco Herrera
Imbalanced classification is related to those problems that have an uneven distribution among classes. In addition to the former, when instances are located into the overlapped areas, the correct modeling of the problem becomes harder. Current solutions for both issues are often focused on the binary case study, as multi-class datasets require an additional effort to be addressed. In this research, we overcome these problems by carrying out a combination between feature and instance selections. Feature selection will allow simplifying the overlapping areas easing the generation of rules to distinguish among the classes...

Loop diuretics are recommended for relieving symptoms and signs of congestion in patients with chronic heart failure and are administered to more than 80% of them. However, several of their effects have not systematically been studied. Numerous cohort and four interventional studies have addressed the effect of diuretics on renal function; apart from one prospective study, which showed that diuretics withdrawal is accompanied by increase in some markers of early-detected renal injury, all others converge to the conclusion that diuretics receipt, especially in high doses is associated with increased rates of renal dysfunction...

BACKGROUND: Huntington disease (HD) is a fatal neurodegenerative disorder involving reduced muscle coordination, mental and behavioral changes, and testicular degeneration. In order to further clarify the decreased fertility and penetration ability of the spermatozoa of transgenic HD minipig boars (TgHD), we applied a set of mitochondrial metabolism (MM) parameter measurements to this promising biological material, which can be collected noninvasively in longitudinal studies. OBJECTIVE: We aimed to optimize methods for MM measurements in spermatozoa and to establish possible biomarkers of HD in TgHD spermatozoa expressing the N-terminal part of mutated human huntingtin...

REVIEW
Mohamed A Kharfan-Dabaja, Mahmoud Aljurf
Hematopoietic cell transplantation (HCT), particularly allogeneic HCT, is a complex and a high-risk procedure requiring expertise to manage potential treatment complications. Published data supports the value of quality management systems in improving post-transplant outcomes; however, there are no universally established, or agreed upon, criteria to assess adequacy of training of physicians, transplant or nontransplant, and supporting staff, among others. It is of paramount importance for transplant centers to identify the needed area(s) of expertise in order to seek appropriate training for their staff...

Tetanus is declining due to vaccination, professional labor management and appropriate wound care. Tetanus cases have been reported despite immunization. We report the case of a previously healthy 21 years old female patient that presented a mild generalized tetanus requiring admission after mild and recurrent cat scratch and bites. She had received six vaccine shots during childhood, and a booster dose five years earlier after a rabbit bite. Symptoms appeared seven weeks after the last contact, and included headache, muscle spasms and mild opisthotonus...

OBJECTIVE: To evaluate the short-term effects of feed fortification, feed volume increase, and PRBC transfusion on the odds of developing NEC. STUDY DESIGN: Case-crossover study of neonatal intensive care infants born at ≤ 32 weeks' gestation who were admitted to 5 central Ohio intensive care units from January 2012-July 2016 and developed NEC Bell Stage ≥2. Each patient served as their own control, with exposure during the 48-hour period just prior to NEC onset (hazard period) being compared to a preceding 48-hour control period, thus eliminating confounding by patient factors fixed between both intervals...

Current automatic dose rate controls (ADRCs) of dynamic x-ray imaging systems adjust acquisition parameters in response to changes in patient thickness in order to achieve a constant signal level in the image receptor. This work compares a 3 parameter (3P) ADRC control to a more flexible 5-parameter (5P) method to meet this goal. A phantom composed of 15 composite poly(methyl) methacrylate (PMMA)/aluminium (Al) plates was imaged on a Siemens Artis Q dynamic system using standard 3P and 5P ADRC technique. Phantom thickness covered a water equivalent thickness range of 2...

The COMQ-12 questionnaire has been elaborated to evaluate the deterioration in the quality of life of the subjects suffering from chronic suppurative otitis media (CSOM) based on the reports of the patients themselves. This questionnaire is of special interest in that it allows to register the complaints of the patients stated by them in the order of priority beginning from those that are responsible for the most pronounced manifestations of the impairment in the quality of life. It, in turn, helps the medical practitioner to rationally organize the treatment of a concrete patient taking into consideration his or her individual expectations...
