BACKGROUND/OBJECTIVES: The risk of chronic kidney disease (CKD) in individuals who regularly drink coffee is controversial. The aim of this meta-analysis was to evaluate the association between coffee consumption and CKD. METHODS: A literature search was performed using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from inception until April 2016. We included studies that reported odd ratios or hazard ratios comparing the risk of CKD in individuals consuming significant amount of coffee vs...

BACKGROUND: Infectious mononucleosis (IM) is a clinical syndrome, usually caused by the Epstein Barr virus (EPV), characterised by lymphadenopathy, fever and sore throat. Most cases of symptomatic IM occur in older teenagers or young adults. Usually IM is a benign self-limiting illness and requires only symptomatic treatment. However, occasionally the disease course can be complicated or prolonged and lead to decreased productivity in terms of school or work. Antiviral medications have been used to treat IM, but the use of antivirals for IM is controversial...

REVIEW
Brock A Lindsey, Justin E Markel, Eugenie S Kleinerman
Osteosarcoma (OS) is the most common primary malignancy of bone and patients with metastatic disease or recurrences continue to have very poor outcomes. Unfortunately, little prognostic improvement has been generated from the last 20 years of research and a new perspective is warranted. OS is extremely heterogeneous in both its origins and manifestations. Although multiple associations have been made between the development of osteosarcoma and race, gender, age, various genomic alterations, and exposure situations among others, the etiology remains unclear and controversial...

Whether the extreme conditions of acidity and heavy metal pollution of streams and rivers originating in pyritic formations are caused primarily by mining activities or by natural activities of metal-oxidizing microbes living within the geological formations is a subject of considerable controversy. Most microbiological studies of such waters have so far focused on acid mine drainage sites, which are heavily human-impacted environments, so it has been problematic to eliminate the human factor in the question of the origin of the key metal compounds...

There is controversy regarding prognosis and treatment of young patients with oral cavity cancer compared to their older counterparts. We conducted a retrospective case-matched analysis of all adult patients younger than 40 years and treated at our institution for a squamous cell carcinoma of the oral cavity. Only non-metastatic adult patients (age >18) with oral tongue cancer were eventually included and matched 1:1 with patients over 40 years of age, at least 20 years older than the cases, with same T and N category and treatment period...

This report describes a stenting technique used to anatomically reconstruct superior vena cava (SVC) bifurcation in a patient with benign SVC syndrome. After recanalizing the SVC bifurcation, we exchanged two 0.035-in. wires for two 0.018-in. wires, deployed the SVC stent over these two wires ("train-track" technique), and stented each innominate vein over one wire. However, our decisions to recanalize both innominate veins, use the "buddy-wire" technique for SVC dilation, and dilate the SVC to 16 mm before stent deployment likely contributed to SVC tear, which was managed by resuscitation, SVC stent placement, and pericardial drainage...

The burden of non-communicable diseases has increased exponentially over the past decade and they account for majority of the health-related morbidity and mortality worldwide. In line with this, the prevalence of chronic kidney disease (CKD) has been increasing over the years. CKD progresses through stages and it is well known that patients are more likely to die than to progress to end-stage renal disease. The presence of multiple classical and novel risk factors predisposes this group of patients to premature cardiovascular mortality...

Obesity-related adipose tissue (AT) inflammation that promotes metabolic dysregulation is associated with increased AT mast cell numbers. Mast cells are potent inducers of inflammatory responses and could potentially contribute to obesity-induced AT inflammation and metabolic dysregulation. Conflicting findings were reported on obesity-related metabolic dysfunction in mast cell-deficient mice, thus creating a controversy that has not been resolved to date. Whereas traditional Kit hypomorphic mast cell-deficient strains featured reduced diet-induced obesity and diabetes, a Kit-independent model of mast cell deficiency, Cpa3(Cre/+) mice, displayed no alterations in obesity and insulin sensitivity...

The Dress photograph, first displayed on the internet in 2015, revealed stunning individual differences in color perception. The aim of this study was to investigate if lay-persons believed that the question about The Dress colors was answerable. Past research has found that optimism is related to judgments of how answerable knowledge questions with controversial answers are (Karlsson et al., 2016). Furthermore, familiarity with a question can create a feeling of knowing the answer (Reder and Ritter, 1992)...

REVIEW
Abdel-Ghani Azzouqa, James P Stevenson
Malignant pleural mesothelioma is an uncommon and aggressive thoracic malignancy that is rarely curable, even when multimodality therapy is used. Systemic chemotherapy is the primary treatment for the majority of patients with this disease; however, surgical resection may benefit a subset of patients with early-stage disease. The surgical approach that offers the best outcomes remains an area of controversy, with data from retrospective comparisons being the only guide. Historically, extrapleural pneumonectomy (EPP) has been the standard procedure, carrying with it a cost of significant morbidity and impact on quality of life that has raised questions regarding its routine application...

PURPOSE: Patients with COPD often experience skeletal muscle dysfunction. For those who are unable or unwilling to undertake physical training, neuromuscular electrical stimulation (NMES) may provide an alternative method of rehabilitation. The purpose of this meta-analysis was to investigate the controversial topic of whether this therapy is effective in patients with moderate-to-severe COPD. PATIENTS AND METHODS: We pooled data from nine trials published between January 9, 2002 and January 4, 2016 across PubMed, Embase, Cochrane Central Register of Controlled Trials, Google Scholar, and relevant websites for randomized controlled trials...

Sildenafil relaxes vascular smooth muscle cells and is used to treat pulmonary artery hypertension as well as erectile dysfunction. However, the effectiveness of sildenafil on skeletal muscle and the benefit of its clinical use have been controversial, and most studies focus primarily on tissues and organs from disease models without cellular examination. Here, the effects of sildenafil on skeletal muscle at the cellular level were examined using mouse primary skeletal myoblasts (the proliferative form of skeletal muscle stem cells) and myotubes, along with single-cell Ca(2+) imaging experiments and cellular and biochemical studies...

BACKGROUND: The significance of mammalian target of rapamycin complex 1 (mTORC1) activity in the maintenance of cancer stem cells (CSCs) remains controversial. Previous findings showed that mTORC1 activation depleted the population of leukemia stem cells in leukemia, while maintaining the stemness in pancreatic CSCs. The purpose of this study was to examine the currently unknown role and significance of mTORC1 activity in brain tumor stem cells (BTSCs). METHODS: Basal mTORC1 activity and its kinetics were investigated in BTSC clones isolated from patients with glioblastoma and their differentiated progenies (DIFFs)...

REVIEW
Jack M Fletcher, Jeremy Miciak
There is considerable controversy about the necessity of cognitive assessment as part of an evaluation for learning and attention problems. The controversy should be adjudicated through an evaluation of empirical research. We review five sources of evidence commonly provided as support for cognitive assessment as part of the learning disability (LD) identification process, highlighting significant gaps in empirical research and where existing evidence is insufficient to establish the reliability and validity of cognitive assessments used in this way...

INTRODUCTION: Lymph node dissection (LND) performed during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) remains controversial and difficult to evaluate. The aim of this study was to investigate whether removal of more lymph nodes during RNU is safe and improves oncologic outcomes. METHODS: We evaluated 422 patients who underwent RNU with concomitant LND for upper tract urothelial carcinoma between 1976 and 2015, assessing for an association between total nodes removed, recurrence-free survival, and cancer-specific survival using Cox proportional hazards models...

BACKGROUND: There is still controversy about which preservation solution in pancreas transplantation could be the best. The aim of this study was to analyze our initial experience with Custodiol solution (CuS) compared with Viaspan solution (VS) and Celsior solution (CS) in pancreas transplantation. METHODS: A retrospective study included 94 consecutive pancreatic transplants, from 2007 until 2015. We compared 3 groups, depending on preservation solution: Viaspan (n = 41), Celsior (n = 40), or Custodiol (n = 13)...

BACKGROUND AND AIMS: The 6-minute withdrawal time for colonoscopy, widely considered the standard of care is controversial; the skill and technique of endoscopists may be as important, or more important than withdrawal time, for adenoma detection. It is unclear whether a shorter withdrawal time with good technique yields an acceptable lesion detection rate. Our objective was to evaluate a 3-minute versus a 6-minute withdrawal time using segmental tandem colonoscopy. METHODS: We performed a prospective, randomized trial using 4 expert endoscopists...

BACKGROUND: Treatment of unstable thoraco-lumbar fractures remains controversial. Long-segment pedicle screw constructs may be stiffer and impart greater forces on adjacent segments compared with short-segment constructs.Short-segment pedicle screw fixation alone may be associated with instrumentation failure. Reinforcement fractured vertebra by additional two screws at fracture level may be usefull in thoraco-lumbar fractures for restoration of anterior vertebral height. MATERIAL AND METHODS: We retrospectively analyzed 38 (22 males, 16 females) unstable thoracolumbar fractures...
