Abstract
Background The prevalence of varicoceles is estimated to be 15% in the general population but is nearly 35% among men with primary infertility and increases by 10% with each decade of life. Studies among adults infer a higher rate of varicoceles among first-degree relatives of patients with varicoceles. However, these studies do not consider the presence of varicoceles, or other venous abnormalities, at the time of desired paternity in first-degree relatives of adolescent patients. Our aim was to document the prevalence of varicoceles and varicose veins among first-degree relatives of pediatric patients diagnosed with varicoceles. Methods A series of 884 patients between the ages of 17 and 22 diagnosed with a varicocele were contacted and of the responders, permission was asked to discuss family history. Each patient underwent a telephone survey regarding the presence of a varicocele in the father prior to achieving paternity, the presence of a varicocele in brothers in childhood, or varicose veins in the father and mother prior to achieving pregnancy. If a varicocele or varicose vein was present, a history of intervention was surveyed. Descriptive statistics were performed to assess overall prevalence of varicocele and varicose veins in first-degree relatives. Chi-squared and logistic regression analyses were performed. Results In total, 152 patients (17.2%) responded and 139 (91.4%) consented to the telephone survey (mean age 19.5±1.84 years old). Overall, 12.9% of fathers had varicoceles and 8.6% of fathers underwent surgical intervention. Among siblings, 18 individuals had a varicocele and 5.6% of siblings with varicocele required intervention. Varicose veins were diagnosed in 7.9% of fathers and 25.2% of mothers; 8.6% of mothers underwent intervention. Surveillance was employed in 76.3% of patients, and surgery undertaken 21.6%. Patients with grade 2 or 3 varicoceles were more likely to have a father with a varicocele than those with grade 1 varicocele (P=0.037). Patients with grade 2 varicocele were more likely to have a father who required varicocele surgery than grade 1 (P=0.019). There was no statistical association of adolescent varicocele and varicose veins in first degree relatives (P=0.306). Conclusions This series shows that while a father’s prevalence is similar to that of the general population, higher grade varicoceles were associated with a higher prevalence of varicoceles and surgical ligation. This suggests the existence of a hereditary predisposition to high grade varicoceles. Furthermore, varicocele is not associated with varicose veins in first degree relatives.

Abstract
ZusammenfassungDie Prognose der spontanen intrazerebralen Massenblutungen gleich welcher Ätiologie ist nach wie vor ungünstig. Weder die konservative Therapie noch das konventionelle neurochirurgische Vorgehen konnten die hohen Mortalitäts-und Morbiditätsraten wesentlich senken.Die CT-stereotaktische Hämatomteilentleerung mit anschließender Fibrinolyse des Resthämatoms stellt hierzu eine effektive therapeutische Alternative dar.Von Oktober 1985 bis August 1988 wurden in der Abt. Stereotaxie und Neuronuklearmedizin der Neurochirurgischen Universitätsklinik Freiburg insgesamt 60 Patienten mit dieser Methode behandelt. Während des Beobachtungszeitraums von durchschnittlich 27 Monaten verstarben insgesamt 15 Patienten, 10 davon innerhalb der ersten 60 Tage unmittelbar an den Blutungsfolgen. Die aktuelle Lebensqualität der 45 überlebenden Patienten wurde nach der Karnofsky-Skala beurteilt. Sie war zum Nachuntersuchungszeitpunkt in 64,4% der Fälle sehr gut bis gut und in 28,9% mäßig. Nur 6,7% der Patienten waren schwer krank und benötigten spezielle Betreuung.Die Langzeitergebnisse der stereotaktischen Behandlungsmethode bei intrazerebralen Blutungen sind somit, verglichen mit den Angaben in der Literatur, deutlich günstiger und daher ermutigend. Durch frühzeitiges Einleiten einer intensiven neurologischen Rehabilitationsbehandlung mit optimaler Hilfsmittelversorgung lassen sich die Resultate wahrscheinlich noch verbessern.

Abstract
BACKGROUND Response Evaluation Criteria in Solid Tumors (RECIST) permits rapid evaluation of new therapeutic strategies in cancer. However, RECIST does not capture the heterogeneity of response in highly active therapies. Depth of tumor response may provide a more granular view of response. We explored the association between, depth of response (DepOR), with overall survival (OS) and progression-free survival (PFS) for patients with NSCLC being treated with an ALK inhibitor (ALKi) or an anti-PD-1 antibody (Ab). METHODS Experimental arms from two randomized controlled trials (RCTs) of an ALKi and two RCTs of an anti-PD-1 Ab were separately pooled. Patient responses were grouped into DepOR 'quartiles' by percentage of maximal tumor shrinkage (Q1 = 1%-25%, Q2 = 26%-50%, Q3 = 51%-75%, and Q4 = 76%-100%), Q0 had no shrinkage. We carried out a retrospective exploratory responder analysis to evaluate the association between DepOR and OS or PFS using hazard ratios (HR) generated by the Cox proportional hazards model. RESULTS In the pooled ALK analysis there were 12, 39, 70, 144, and 40 patients in quartiles 0-4, respectively. The DepOR versus PFS/OS analyses HR were: 0.19/0.94 for Q1 0.11/0.56 for Q2, 0.05/0.28 for Q3, and 0.03/0.05 for Q4. In the PD-1 trials within quartiles 0-4 there were 168, 70, 44, 45, and 28 patients, respectively. The DepOR versus PFS/OS analyses HR were 0.3/0.52 for Q1, 0.22/0.47 for Q2, 0.09/0.07 for Q3, and 0.07/0.14 for Q4. CONCLUSIONS Our analysis suggests a greater DepOR is associated with longer PFS and OS for patients receiving ALKi or anti-PD1 Ab. Overall, this suggests that DepOR may provide an additional outcome measure for clinical trials, and may allow better comparisons of treatment activity.

Abstract
A wearable skin hydration sensor in the form of a capacitor is demonstrated based on skin impedance measurement. The capacitor consists of two interdigitated or parallel electrodes that are made of silver nanowires (AgNWs) in a polydimethylsiloxane (PDMS) matrix. The flexible and stretchable nature of the AgNW/PDMS electrode allows conformal contact to the skin. The hydration sensor is insensitive to the external humidity change and is calibrated against a commercial skin hydration system on an artificial skin over a wide hydration range. The hydration sensor is packaged into a flexible wristband, together with a network analyzer chip, a button cell battery, and an ultralow power microprocessor with Bluetooth. In addition, a chest patch consisting of a strain sensor, three electrocardiography electrodes, and a skin hydration sensor is developed for multimodal sensing. The wearable wristband and chest patch may be used for low-cost, wireless, and continuous monitoring of skin hydration and other health parameters.

Fludarabine with pharmacokinetically guided IV busulfan is superior to fixed-dose delivery in pretransplant conditioning of AML/MDS patients. Bone Marrow Transplant 2016; 52:580-587.

Abstract
We hypothesized that IV Busulfan (Bu) dosing could be safely intensified through pharmacokinetic (PK-) dose guidance to minimize the inter-patient variability in systemic exposure (SE) associated with body-sized dosing, and this should improve outcome of AML/MDS patients undergoing allogeneic stem cell transplantation (allo-HSCT). To test this hypothesis, we treated 218 patients (median age 50.7 years, male/female 50/50%) with fludarabine (Flu) 40 mg/m2 once daily ×4, each dose followed by IV Bu, randomized to 130 mg/m2 (N=107) or PK-guided to average daily SE, AUC of 6,000 µM-min (N=111), stratified for remission-status, and allo-grafting from HLA-matched donors. Toxicity and graft vs. host disease (GvHD) rates in the groups were similar; the risk of relapse or treatment-related mortality remained higher in the fixed-dose group throughout the 80-month observation period. Further, PK-guidance yielded safer disease-control, leading to improved overall and progression-free survival, most prominently in MDS-patients and in AML-patients not in remission at allo-HSCT. We conclude that AML/MDS patients receiving pretransplant conditioning treatment with our 4-day regimen may benefit significantly from PK-guided Bu-dosing. This could be considered an alternative to fixed dose delivery since it provides the benefit of precise dose delivery to a predetermined SE without increasing risk(s) of serious toxicity and/or GvHD.

Abstract
An 82-year-old woman with longstanding medial thigh pain presented with a 5-day history of constipation, vomiting, abdominal pain and distension. She was unable to pass flatus for the preceding 24 hours and had a past history of laparoscopic abdominal surgery. Computed tomography of the abdomen and pelvis revealed a right-sided obturator hernia containing a dilated loop of small bowel. She underwent emergency surgery for a right obturator hernia repair by limited laparotomy and was discharged after an extended stay complicated by postoperative atrial fibrillation.

Abstract
OBJECTIVES The Accreditation Council for Graduate Medical Education (ACGME) emphasizes the importance of medical trainees meeting specific performance benchmarks and demonstrating readiness for unsupervised practice. The aim of this study was to examine the readiness of Gastroenterology (GI) fellowship programs for competency-based evaluation in endoscopic procedural training. METHODS ACGME-accredited GI program directors (PDs) and GI trainees nationwide completed an online survey of domains relevant to endoscopy training and competency assessment. Participants were queried about current methods and perceived quality of endoscopy training and assessment of competence. Participants were also queried about factors deemed important in endoscopy competence assessment. Five-point Likert items were analyzed as continuous variables by an independent t-test and χ(2)-test was used for comparison of proportions. RESULTS Survey response rate was 64% (94/148) for PDs and 47% (546/1,167) for trainees. Twenty-three percent of surveyed PDs reported that they do not have a formal endoscopy curriculum. PDs placed less importance (1—very important to 5—very unimportant) on endoscopy volume (1.57 vs. 1.18, P<0.001), adenoma detection rate (2.00 vs. 1.53, P<0.001), and withdrawal times (1.96 vs. 1.68, P=0.009) in determining endoscopy competence compared with trainees. A majority of PDs report that competence is assessed by procedure volume (85%) and teaching attending evaluations (96%). Only a minority of programs use skills assessment tools (30%) or specific quality metrics (28%). Specific competencies are mostly assessed by individual teaching attending feedback as opposed to official documentation or feedback from a PD. PDs rate the overall quality of their endoscopy training and assessment of competence as better than overall ratings by trainees. CONCLUSIONS Although the majority of PDs and trainees nationwide believe that measuring specific metrics is important in determining endoscopy competence, most programs still rely on procedure volume and subjective attending evaluations to determine overall competence. As medical training transitions from an apprenticeship model to competency-based education, there is a need for improved endoscopy curricula which are better suited to demonstrate readiness for unsupervised practice.

Abstract
Wearable electrodes made of silver nanowires (AgNWs) have demonstrated great potential for sensing a variety of physical and physiological signals. This paper aimed to study the feasibility of AgNWs electrodes for measuring surface electromyographic (sEMG) signals. One human subject was recruited and instructed to perform wrist extension repetitively or to produce no movement in the experiment. sEMG signals were collected from the right extensor digitorum communis of the human subject by an AgNWs electrode and a commercially available Ag/AgCl wet sEMG electrode, separately. The quality of recorded sEMG in time and frequency domains was compared between the two types of electrodes. The results showed that the sEMG signals recorded by the AgNW electrode were comparable with that by the Ag/AgCl electrode. Since the dry AgNWs electrodes are flexible, wearable, and potentially robust for daily use, novel AgNW-based EMG electrodes are promising for many biomedical applications, such as myoelectric control of artificial limbs.
