Published: January 2017

Background: Rectus femoris injuries are common among athletes, especially in kicking sports such as soccer; however, proximal rectus femoris avulsions in athletes are a relatively rare entity. Purpose/Hypothesis: The purpose of this study was to describe and report the results of an original technique of surgical excision of the proximal tendon remnant followed by a muscular suture repair. Our hypothesis was that this technique limits the risk of recurrence in high-level athletes and allows for rapid recovery without loss of quadriceps strength. Study Design: Case series; Level of evidence, 4. Methods: Our retrospective series included 5 players aged 31.8 ± 3.9 years with acute proximal rectus femoris avulsion injuries who underwent a surgical resection of the proximal tendon between March 2012 and June 2014. Four of these players had recurrent rectus femoris injuries in the 9 months before surgery, while 1 player had surgery after a first injury. Mean follow-up was 18.2 ± 12.6 months, and minimum follow-up was 9 months. We analyzed the age, sex distribution, physical examination outcomes, type and mechanism of injury, diagnosis, treatment and complications during surgery, postoperative follow-up, and time to return to play. The Lower Extremity Functional Scale (LEFS) and Marx scores were obtained at 3-month follow-up, and isokinetic tests were performed before return to sports. A telephone interview was completed to determine the presence of recurrence at an average follow-up of 18.2 months. Results: At 3-month follow-up, all patients had Marx activity scores of 16 and LEFS scores of 80. Return to the previous level of play occurred at a mean of 15.8 ± 2.6 weeks after surgery, and none of the athletes suffered a recurrence. Isokinetic test results were comparable between both sides. Conclusion: The surgical treatment of proximal rectus femoris avulsions, consisting of resection of the tendinous part of the muscle, is a reliable and safe technique allowing a fast recovery in professional athletes.

Authors: Cheng Eugene Y. , Stevens Rom A. , Stommel Kimberly A. , Roerig David L. 
Published: January 2017

Objective: To determine analgesic qualities of epidural sufentanil, associated plasma concentrations, and incidence of adverse effects. Design: Case series. Setting: Postanesthesia care unit of a tertiary care facility. Patients: Thirteen patients undergoing elective intraabdominal surgery. Interventions: Postsurgical analgesia was maintained with epidural sufentanil infusion (0.3–0.6 μg/kg/h). Epidural boluses of sufentanil 0.3 μg/kg had been administered prior to sufentanil infusion to achieve adequate analgesia. Main Outcome Measures: Quality of analgesia was measured with a visual analog scale (VAS). Adverse effects measured included nausea, vomiting, and pruritus. Respiratory function was monitored with end-tidal CO2, pulse oximetry, and respiratory rate. To determine systemic absorption, plasma concentrations of sufentanil were measured. Results: Analgesia occurred within five minutes after bolus epidural sufentanil injection. Mean ± SEM VAS scores decreased from 6.2 ± 0.7 at time 0 to 2.4 ± 0.6 after five minutes and were less than three over the next eight hours. One of 13 patients became nauseated and one experienced hypotension and respiratory depression during the study period. Mean plasma sufentanil concentrations were <0.1 ng/mL for the first seven hours and at the lower limits of assay detection (0.1 ng/mL) during hour 8. After 24 and 48 hours of epidural sufentanil infusion, the mean plasma sufentanil concentration was 0.4 ± 0.1 (n=8) and 0.4 ± 0.1 ng/mL (n=4), respectively. Conclusions: These data suggest that epidural sufentanil can provide rapid postoperative analgesia. Plasma sufentanil concentration tends to increase with the duration of infusion, which could increase the risk of respiratory depression.

Published: January 2017

Objective: To report the first case series study of two patients who developed parotid gland swelling while taking clozapine. Case Summaries: Transient, unilateral parotid swelling was noted in two patients who were on clozapine. Discussion: Some patients who have hypersalivation develop unilateral parotid swelling. The swelling tends to resolve spontaneously within a few hours. Conclusions: Clinicians should be aware of this potential spontaneously reversible reaction. J Pharm Technol 1995;11:18–20.
Reducing Inappropriate Prescribing of Sublingual Nifedipine
Authors: Yasuda Sally U. , Woosley Raymond L. 
Published: January 2017

Objective: To report a program to reduce the practice of prescribing sublingual nifedipine. Monitoring and Educational Program: Pharmacy records were used to identify orders for sublingual nifedipine at Georgetown University Medical Center. Initial review showed 30–40 orders/month, or approximately 11 % of all nifedipine orders. A newsletter was published outlining Pharmacy and Therapeutics Committee guidelines for the use of nifedipine when rapid onset of action is desired. Further educational efforts involved correspondence with each attending physician responsible for the sublingual nifedipine orders. A reduction in orders for sublingual nifedipine to approximately 10 orders/month (3.9% of total nifedipine orders) was observed after using this educational approach. The reduction in orders has been maintained by frequent contact with the attending physicians. Conclusions: Repeated educational measures have resulted in a reduction in the inappropriate prescribing of sublingual nifedipine.
RETRACTED ARTICLE: Effect of Paclitaxel-Mesoporous Silica Nanoparticles with a Core-Shell Structure on the Human Lung Cancer Cell Line A549
Authors: Wang Tieliang , Liu Ying , Wu Chao 
Published: January 2017

AbstractA nanodrug delivery system of paclitaxel-mesoporous silica nanoparticles with a core-shell structure (PAC-csMSN) was used to increase the dissolution of paclitaxel (PAC) and improve its treatment of lung cancer. PAC was loaded into the core-shell mesoporous silica nanoparticles (csMSN) by the adsorption equilibrium method and was in an amorphous state in terms of its mesoporous structure. In vitro and in vivo studies showed that csMSN increased the dissolution rate of PAC and improved its lung absorption. The area under concentration-time curve (AUC) value of PAC-csMSN used for pulmonary delivery in rabbits was 2.678-fold higher than that obtained with the PAC. After continuous administration for 3 days, a lung biopsy showed no signs of inflammation. Cell apoptosis results obtained by flow cytometry indicated that PAC-csMSN was more potent than pure PAC in promoting cell apoptosis. An absorption investigation of PAC-csMSN in A549 cells was carried out by transmission electron microscopy (TEM) and laser scanning confocal microscopy (LSCM). The obtained results indicated that the cellular uptake was time-dependent and csMSN was uptaken into the cytoplasm. All these results demonstrate that csMSN have the potential to achieve pulmonary inhalation administration of poorly water-soluble drugs for the treatment of lung cancer.
Field-of-study mismatch and overqualification: labour market correlates and their wage penalty
Authors: Montt Guillermo 
Published: January 2017

AbstractField-of-study mismatch occurs when a worker, trained in a particular field, works in another field. This study draws on the Survey of Adult Skills (PIAAC) to explore how skill supply and labour market demand dynamics influence mismatch. It updates cross-national estimates on mismatch and estimates the mismatch wage penalty. Findings suggest that around 40% of workers are mismatched by field at their qualification level, 11% overqualified in their field and 13% overqualified and working outside their field. The saturation of the field in the labour market and the transferability of the fields’ skills predict the incidence of field-of-study mismatch and overqualification. Workers who are mismatched by field only suffer a wage penalty if they are overqualified.

Published: January 2017

AbstractArthrobacter sp. B6 is a Gram-positive, non-motile, facultative aerobic bacterium, isolated from the arsenic-contaminated aquifer sediment in the Datong basin, China. This strain displays high resistance to arsenic, and can dynamically transform arsenic under aerobic condition. Here, we described the high quality draft genome sequence, annotations and the features of Arthrobacter sp. B6. The G + C content of the genome is 64.67%. This strain has a genome size of 4,663,437 bp; the genome is arranged in 8 scaffolds that contain 25 contigs. From the sequences, 3956 protein-coding genes, 264 pseudo genes and 89 tRNA/rRNA-encoding genes were identified. The genome analysis of this strain helps to better understand the mechanism by which the microbe efficiently tolerates arsenic in the arsenic-contaminated environment.
Information Sharing, Advice Provision, or Delegation: What Leads to Higher Trust and Trustworthiness?
Authors: Özer Özalp , Subramanian Upender , Wang Yu 
Published: January 2017

In many market settings, a customer often obtains assistance from a supplier (or service provider) to make better-informed decisions regarding the supplier’s product (or service). Because the two parties often have conflicting pecuniary incentives, customer trust and supplier trustworthiness play important roles in the success of these interactions. We investigate whether and how the process through which assistance is provided can foster trust and trustworthiness, and thus facilitate better cooperation. We compare three prevalent assistance processes: information sharing, advice provision, and delegation. We propose that, even if the pecuniary incentives of both parties do not vary from one assistance process to another, the assistance process itself impacts the customer’s and supplier’s nonpecuniary motives that give rise to trust and trustworthiness. Consequently, the assistance process affects the level of cooperation and payoffs. We test our behavioral predictions through laboratory experiments based on a retail distribution setting. We quantify the impact of different assistance processes on trust, trustworthiness and channel performance, and identify the underlying drivers of those impacts. Our results offer insight into the role of the assistance process in managing supplier assistance effectively and why certain assistance processes may lead to more successful outcomes than others even if the pecuniary incentives remain unaltered.

Published: January 2017

Objective: The aim of this study was to evaluate the adhesion of a self-etching system to caries-affected dentin (CAD) and sound dentin (SD) after different caries removal techniques by using microtensile bond strength test (?TBS). Materials and Methods: Twenty-four extracted human molars with coronal carious lesions were used. The samples were randomly divided into 5 groups, according to caries removal method: G1 - negative control (no removal); G2 abrasive disc; G3 – slow speed steel bur; G4 - Nd:YAG laser (energy density 21.2J/cm2); G5 - Er:YAG laser (energy density 80.24J/cm2). SD and CAD/ infected dentin substrates were tested. Self-etch system (Clearfil SE Bond) was applied and resin crowns were built up. Results: One-way ANOVA showed statistically significant difference between experimental groups (p<0.001), with significantly lower results for infected dentin (G1), when compared to all other experimental groups. A statistically significant higher bond strength value was observed for SD irradiated with Er:YAG laser when compared to CAD. For bur and Nd:YAG laser specimens, SD and CAD showed the same bonding performance. Conclusion: infected dentin is not an adequate substrate for bonding; Nd:YAG laser and steel burs showed the same bonding performance for both SD and CAD; while both dentins, when irradiated by Er:YAG laser, did not adequately interact with self-etching system resulting in poor adhesion.Keywords: Er:YAG laser; Nd:YAG laser; Infected dentin; Dentin.

Published: January 2017

Objective: To compare the visual-tactile examination with the technology-based caries detection examinations in children. Methods: We assessed the teeth next to the cleft area of 95 children aged 6 to 12 years with oral clefts but without the presence of any associated syndrome or craniofacial anomaly, according to the following detection methods: visual-tactile examination (Method 1), visual-tactile examination through operating microscope (Method 2), visual examination through LED-based fluorescence device (Method 3), using ICDAS-II scores. The caries detection methods were compared by Friedman test (P<0.05). Results: The efficacy of carious lesion detection methods were statistically similar (P=0.786). Conclusions: Technology-based devices did not improve caries diagnosis in children because their results were similar to those of visual-tactile clinical examination. From a clinical point of view, we recommended the dentists to be cautious in using these additional diagnostic measures to avoid false positive errors mainly in tooth surfaces difficult to be examined.Keywords: Dental Caries.

Abstract
A series of mono-, di- and tetranuclear copper(I) complexes with macrocyclic 14-, 16-, 18- and 20-membered tetrakis-phosphine ligands (P4N2) was obtained and fully characterized including single crystal X-ray diffraction. The 14-membered P4N2 macrocycles form very stable cationic mononuclear tetraphospha-coordinated copper(I) complexes, whereas their higher 16-, 18- and 20-membered homologues give neutral dinuclear [Cu2I2L] complexes under the same conditions. An unusual tetranuclear complex with two three- and two four-coordinated copper(I) atoms was obtained from 16-PMes
4NCH2CH2Py-2
2 and copper(I) iodide. This is the first example of N-coordination of cyclic aminomethylphosphines towards “soft” copper(I).
Consent by Proxy for Nonurgent Pediatric Care

This Clinical Report was reaffirmed November 2024.
Minor-aged patients are often brought to the pediatrician for nonurgent acute medical care, physical examinations, or health supervision visits by someone other than their legally authorized representative, which, in most situations, is a parent. These surrogates or proxies can be members of the child’s extended family, such as a grandparent, adult sibling, or aunt/uncle; a noncustodial parent or stepparent in cases of divorce and remarriage; an adult who lives in the home but is not biologically or legally related to the child; or even a child care provider (eg, au pair, nanny, private-duty nurse/nurse’s aide, group home supervisor). This report identifies common situations in which pediatricians may encounter “consent by proxy” for nonurgent medical care for minors, including physical examinations, and explains the potential for liability exposure associated with these circumstances. The report suggests practical steps that balance the need to minimize the physician’s liability exposure with the patient’s access to health care. Key issues to be considered when creating or updating office policies for obtaining and documenting consent by proxy are offered.
The Annales School and the Environmental History of Latin America
Authors: Tortolero Villaseñor Alejandro 
Published: January 2017

There are different influences in Environmental Latin-American History. From the historical demography to anthropology, this discipline has been benefit from Cook and Borah’s contributions to Carl Sauer’s. In this article, my contribution consists in broading the spectrum towards the European influence and particularly to the so-called Annales School. While it is true that this movement had a strong influence in Latin-American History, in contrast, in Environment Historians, such influence has not been comparable to quantity history or the history of prices. My purpose is to analyze the roots of this influence in Latin America, their scope and limits.
Effect of a therapeutic dose of pseudoephedrine on swimmers’ performance

Published: January 2017

Background. The potential performance-enhancement effect of pseudoephedrine (PSE) use has led to its prohibition in competition sports (urine concentrations >150 μg/ml). Data are, however, scarce regarding whether therapeutic PSE use enhances swimming performance.Objective. To investigate the effect of therapeutic PSE use on performance in aerobic and explosive sprint swimming events.Method. A double-blinded cross-over study design was used. Participants in the control group initially received a placebo and those in the experimental group received a divided PSE dose of 90 mg/d. Anaerobic power (50 m sprint) and aerobic (2 000 m) swimming testing was conducted at (i) baseline; (ii) after ingestion of a placebo or PSE; and (iii) after the groups were crossed over, following a wash-out period of 4 days, to determine changes in performance between trials.Results. The participants (mean age 44 years; N=7) were competitive masters swimmers with normal resting heart rates (68 beats per minute (bpm); standard deviation (SD) ±14) and blood pressures (BPs) (171 (SD ±27)/83 (SD ±16) mmHg). The use of PSE during the anaerobic swim test showed only a trivial chance (68%) of improvement, with a likely enhancement in systolic BP (86%). The aerobic swim test did not affirm performance enhancement as measured by time to completion (52% chance of a positive effect; 41% chance of a negative effect), nor did any other physiological variable of interest (peak heart rate and exercising BP) differ significantly from baseline results.Conclusion. The use of a therapeutic amount of PSE in short and endurance swimming trials did not appear to have any major ergogenic effect on performance.
