Background: Preoperative anemia has been associated with perioperative morbidity and mortality in patients undergoing cardiac and non-cardiac surgery. Preoperative anemia is common in elderly hip fracture patients. The primary objective of the study was to explore the relationship between preoperative hemoglobin levels and postoperative major adverse cardiovascular events (MACEs) in hip fracture patients over 80 years. Methods: The retrospective study enrolled hip fracture patients over 80 years from January 2015 to December 2021 in our center. The data were collected from the hospital's electronic database after approval by the ethics committee. The primary objective of the study was to investigate MACEs, and the secondary objectives included in-hospital mortality, delirium, acute renal failure, ICU admission rate, and transfusion (>2 U). Results: 912 patients were entered for final analysis. Based on the restricted cubic spline, the risk of preoperative hemoglobin (<10 g/DL) was associated with an increased risk of postoperative complications. With univariable logistic analysis, a hemoglobin level <10 g/DL was associated with increased MACEs [OR 1.769, 95% CI (1.074, 2.914), P =.025], in-hospital mortality [OR 2.709, 95% CI (1.215, 6.039), P =.015] and transfusion >2 U risk [OR 2.049, 95% CI (1.56, 2.69), P <.001]. Even after adjustment for confounding factors, MACEs [OR 1.790, 95% CI (1.073, 2.985), P =.026], in-hospital mortality [OR 2.81, 95% CI (1.214, 6.514), P =.016] and transfusion >2 U rate [OR 2.002, 95% CI (1.516, 2.65), P <.001] were still higher in the lower hemoglobin level cohort. Moreover, a log-rank test showed increased in-hospital mortality in the cohort with a preoperative hemoglobin level of <10 g/DL. However, there was no difference in delirium, acute renal failure, and ICU admission rates. Conclusions: In conclusion, for hip fracture patients over 80 years, preoperative hemoglobin levels <10 g/DL might be associated with increased postoperative MACEs, in-hospital mortality, and transfusion >2 U.

Objective: to analyze the profile of nurses regarding integrative and complementary practices in health (ICPH) and understand how they are used in the care of people with arterial hypertension. Method: mixed-methods sequential explanatory design. The cross-sectional quantitative stage included 386 nurses who completed an online questionnaire addressing sociodemographic and professional information, training, and practice, with a descriptive and inferential analysis. The qualitative stage was performed via 18 online interviews with professionals who had ICPH training and implemented it in the care provided to individuals with hypertension, with a participatory analysis. Integration occurred through a connecting approach. Results: 36.8% had ICPH training; most were women, Caucasian, married, public servants, aged 37 (+ 9.4) on average; 14.2% incorporated ICPH into the care provided to people with hypertension; predominantly auriculotherapy (28.2%) and bloodletting in hypertensive crises. The results show that nurses integrally approached patients, and their approach was not limited to the vital sign altered at the time, but they also intervened in anxiety, stress, sleep, and rest. A potentiality observed concerns support treatment adherence. Conclusion: the profile of nurses with ICPH training is presented, and such practice has implications for lowering blood pressure. ICPH has been incorporated into the care of people with hypertension, but its use is still incipient, considering its potential in nursing care. [ABSTRACT FROM AUTHOR]

Background: The prevalence, indications, and preferred methods for gastrocnemius recession and tendo-Achilles lengthening—grouped as triceps surae lengthening (TSL) procedures—in foot and ankle trauma are supported by a scarcity of clinical evidence. We hypothesize that injury, practice environment, and training heritage are significantly associated with probability of performing adjunctive TSL in the operative management of foot and ankle trauma. Methods: A survey was distributed to members of the American Orthopaedic Foot & Ankle Society and the Orthopaedic Trauma Association. Participants rated how likely they would be to perform TSL at initial management, definitive fixation, and after weightbearing in the presence and absence of a positive Silfverskiöld test in 10 clinical scenarios of closed foot and ankle trauma. Results: A total of 258 surgeons with median 14 years' experience responded. Eighty-five percent reported foot and ankle fellowship training, 24% reported traumatology fellowship training, 13% both, and 4% no fellowship. Ninety-nine percent reported performing TSL with a median 25 TSL procedures per year, 72% open gastrocnemius recession, and 17% percutaneous tendo-Achilles lengthening). Across all scenarios, we observed low overall 8% probability with fair agreement (κ = 0.246) of performing TSL (range, 1% at initial management of an unstable Weber B bimalleolar ankle fracture with negative contralateral Silfverskiöld test to 29% at definitive fixation of tongue-type calcaneus fracture with positive contralateral Silfverskiöld test). Silfverskiöld testing significantly influenced TSL probability at all time points. University of Washington training (β = 1.5, P =.007) but not trauma vs foot fellowship training, years in practice, academic practice, urban setting, or facility trauma designation were significantly associated with likelihood of performing TSL. Conclusion: Orthopaedic traumatology and foot and ankle surgeons report similar indications, methods, and low perceived propensity to use TSL in the management of foot and ankle trauma. We found that graduates of 1 fellowship training site were more likely to perform TSL in the setting of acute trauma potentially indicating the need for better scientific data to support this practice. Level of Evidence: Level V, therapeutic. [ABSTRACT FROM AUTHOR]

Background: Examining factors that increase risk of death in veterans with multiple sclerosis (MS) may help reduce MS-related mortality. We sought to determine predictors of mortality in veterans with MS attending an outpatient clinic. Methods: Review of electronic medical records of 226 veterans with MS regularly followed up from January 1, 2000, through December 31, 2014. Results: Mortality at the end of the 15-year study period was 14%. Patients with MS died prematurely, with a standardized mortality rate of 1.35 relative to the general (Oklahoma) population. The main causes of death documented were MS disease itself (57% of cases), infection (43%), and cancer and respiratory failure (18% each). Cox regression analysis using the whole cohort showed that progressive MS type; older age at entry into the study; presence of sensory, cerebellar, or motor (weakness and/or ataxia) concerns on presentation; more disability on presentation; higher body-mass index; being diabetic; never received disease-modifying therapy; and presence of pressure ulcers or neurogenic bladder were significant predictors of higher mortality. Conclusions: Initial presentation by MS type (progressive MS), higher level of disability, and associated motor, sensory, and cerebellar concerns are significant predictors of MS-related mortality. The main causes of death were MS disease itself, infection, respiratory disease, and cancer. More attention should be given to preventive strategies that delay mortality, such as yearly immunization and aggressively treating MS- related complications and diabetes mellitus.

Context: Concussions in student-athletes are a serious problem. Most states have enacted legislation mandating concussion education for student-athletes, under the assumption that education leads to better self-reporting of concussions and improved knowledge of symptoms. Objectives: (1) To determine the effect of state-based concussion legislation on the proportion of student-athletes receiving concussion education and to assess the moderation of this effect by gender and sport and (2) to assess the effect of concussion education on student-athletes' knowledge of concussion symptoms and likelihood of seeking treatment after a concussion. Design: Cross-sectional study. Setting: Private university. Patients or Other Participants: A total of 249 National Association of Intercollegiate Athletics collegiate athletes attending St Xavier University; 160 were surveyed prelegislation and 89 were surveyed postlegislation. Main Outcome Measure(s): Participants completed an anonymous survey that assessed previous involvement in concussion-education programs, degree of self-reporting after a concussion, and ability to enumerate symptoms. Results: The number of athletes who reported having received education increased after the implementation of concussion legislation; however, almost 25% still reported not having received education. Athletes who played football were more likely to report having received education than those who played volleyball. The student-athletes' ability to name a diversity of concussion symptoms or to report seeking medical attention after a concussion did not improve in the postlegislation period relative to the prelegislation period. Conclusions: Legislation has been passed in all 50 states to address concussions in student-athletes; however, improvements are still needed. Concussion education must be delivered in a uniform, effective manner to all student-athletes across sports and genders. Concussion education should emphasize the diversity of symptoms, especially cognitive and behavioral symptoms. We must develop and disseminate evidence-based educational programs that are clinically proven to be effective in improving athletes' knowledge and behaviors. [ABSTRACT FROM AUTHOR]

Context.--Image-guided, fine-needle aspiration--assisted core needle biopsy with an on-site evaluation by a pathologist (FNACBP) of osseous lesions is not a common practice in pediatric institutions. Objectives.--To evaluate the diagnostic adequacy and accuracy of FNACBP for pediatric osseous lesions and to compare the adequacy with procedures that do not use fine-needle aspiration. Design.--Six-year, retrospective review of 144 consecutive children biopsied for osseous lesions with and without fine-needle aspiration assistance. Results.--Pathologic diagnosis was achieved in 79% (57 of 72) of the core biopsies without an on-site evaluation, 78% (32 of 41) of the open biopsies (9 with intraoperative consultation), and 97% (30 of 31) of the FNACBPs as the initial diagnostic procedure. Three FNACBP cases were preceded by nondiagnostic open biopsies. Among 34 lesions sampled by FNACBP, 33 (97%) succeeded with diagnostic tissue, with most (30 of 33; 91%) being neoplasms, including 16 malignant (48%), 13 benign (39%), and 1 indeterminate (3%) lesions. The mostcommon diagnoses were osteosarcoma (9 of 33; 27%) and Langerhans cell histiocytosis (7 of 33; 21%). In cases with follow-up information available, 93% (28 of 30) of the FNACBP-rendered diagnoses were clinically useful, allowing initiation of appropriate therapy. The FNACBP procedure had 100% specificity, sensitivity, and positive predictive value for all 14 malignant lesions, with the sensitivity being 88% in benign lesions. Most FNACBP procedures (32 of 34; 94%) yielded adequate material for ancillary testing. A gradual upward trend was observed for the choice of FNACBP as an initial diagnostic procedure for osseous lesions. Conclusions.--The FNACBP procedure yields sufficient material for diagnosis and ancillary studies in pediatric, osseous lesions and may be considered an initial-diagnostic procedure of choice.

Background: The six-minute walk test (6MWT) is a simple, low cost, reliable, and valid method for evaluating the functional capacity of cardiac patients. However, its early use and safety following acute myocardial infarction (AMI) is recent and has been little investigated. Objective: To evaluate and to compare the safety and the cardiac behavior of early performance of the 6MWT in patients following uncomplicated AMI up to 4 days or more than 4 days after the event. Methods: Following discharge from the Coronary Care Unit, 152 stable asymptomatic patients diagnosed with uncomplicated AMI performed the 6MWT. During the test, in addition to the distance walked, heart rate (HR), blood pressure (BP), and adverse events were also recorded. Electrocardiography was recorded using a Holter monitor in 105 patients. Patients were allocated considering two groups according to the number of days since AMI: Up to 4 Days Group and After 4 Days Group. Results: All patients completed the 6MWT, 66 in the Up to 4 Days Group and 86 in the After 4 Days Group. The walking distance was similar in both groups (85% of the predicted value), as well as the physiological responses (increase in systolic BP and HR), reaching 63% (median) of maximum HR. Only 3.9% of patients had major complications (angina, drop in BP, or ventricular tachycardia), with no difference between the groups. None of the complications regarded as severe led to truly significant complications or death. Conclusion: The 6MWT was proven to be safe and feasible for early functional evaluation following uncomplicated AMI. [ABSTRACT FROM AUTHOR]

Background: India's high prevalence of iron-deficiency anemia has largely been attributed to the local diet consisting of nonheme iron, which has lower absorption than that of heme iron. Objective: We assessed the efficacy of the consumption of ironsupplement bars in raising hemoglobin concentrations and hematocrit percentages in anemic (hemoglobin concentration <12 g/dL) Indian women of reproductive age. Design: The Let's be Well Red study was a 90-d, pair-matched, cluster-randomized controlled trial. A total of 361 nonpregnant women (age 18-35 y) were recruited from 10 sites within Mumbai and Navi Mumbai, India. All participants received anemia education and a complete blood count (CBC). Random assignment of anemic participants to intervention and control arms occurred within 5 matched site-pairs. Intervention participants received 1 iron-supplement bar (containing 14 mg Fe)/d for 90 d, whereas control subjects received nothing. CBC tests were given at days 15, 45, and 90. Primary outcomes were 90-d changes from baseline in hemoglobin concentrations and hematocrit percentages. Linear mixed models and generalized estimating equations were used to model continuous and binary outcomes, respectively. Results: Of 179 anemic participants, 136 (76.0%) completed all follow-up assessments (65 intervention and 71 control participants). Baseline characteristics were comparable by arm. Mean hemoglobin and hematocrit increases after 90 d were greater for intervention than for control participants [1.4 g/dL (95% CI: 1.3, 1.6 g/dL) and 2.7% (95% CI: 2.2%, 3.2%), respectively]. The anemia prevalence at 90 d was lower for intervention (29.2%) than for control participants (98.6%) (OR: 0.007; 95% CI: 0.001, 0.04). Conclusions: The daily consumption of an iron-supplement bar leads to increased hemoglobin concentrations and hematocrit percentages and to a lower anemia prevalence in the target population with no reported side effects. This intervention is an attractive option to combat anemia in India. This trial was registered at clinicaltrials.gov as NCT02032615. [ABSTRACT FROM AUTHOR]

Background: Recent studies have proved metabolic syndrome (MetS) was linked to cancer risks. However, few data has examined the relationship between MetS and epithelial ovarian cancer (EOC). Methods: We conducted a population-based case-control study in Tianjin Medical University Cancer Institute and Hospital, China (2010-2015) that enrolled 573 EOC patients and 1146 matched controls. Data were collected through in-person interviews, anthropometric measurement, and 8-h fasting bloods drawn. MetS was estimated by Chinese Diabetes Society (CDS) definition requiring presence of ≥3 of the following risk factors: 1) body mass index (BMI) ≥25. 0kg/m²,2) fasting plasma glucose ≥6.1 mmol/L or 2-h plasma glucose ≥ 7.8 mmol/L, 3) systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, 4) triglyceride (TG) ≥1.70 mmol/L or high-density lipoprotein cholesterol (HDL-C) < 1.0 mmol/L. Statistics were completed using chi-square tests and logistic regression analysis. The survival analysis was conducted by the Kaplan-Meier method and Cox proportional hazard regression models. Results: MetS was significantly more prevalent among EOC (25.13%) than controls (6.89%). A statistically significant increase risk for EOC was observed for MetS (multivariable-adjusted OR = 3.187; 95% CI: 2.135-4.756). MetS was significantly associated with histological grade (P < 0.001), FIGO stage (P = 0.003), and lymph node (LN) status (P = 0.002) of EOC. In binary logistic regression analysis, the presence of MetS predicts the risk of advanced FIGO stage (OR = 2.155, 95% CI: 1.327-3.498, P = 0.002), lower differentiation (OR = 2.472, 95% CI: 1.164-5.250, P = 0.019), and LN metastasis (OR = 2.590, 95% CI: 1.089-6.160, P = 0.031) of EOC. Moreover, MetS is the independent factor for the evaluation of PFS and OS of EOC patients (both of them P < 0.001) in Cox proportional hazard model. Conclusion: MetS is obviously related to increased EOC risk. EOC patients with MetS in Chinese population were found to have statistically significant tumor advanced stage, low differentiation, LN metastasis and poor prognosis. [ABSTRACT FROM AUTHOR]

Objective The disease process in rheumatoid arthritis (RA) starts years before the clinical diagnosis is made, and elevated levels of disease-specific autoantibodies can be detected during this period. Early responses to known or novel autoantigens likely drive the eventual production of pathogenic autoimmunity. Importantly, the presence of disease-specific autoantibodies can identify individuals who are at high risk of developing RA but who do not currently have arthritis. The goal of the current study was to characterize plasmablasts from individuals at risk of developing RA. Methods We investigated antibody-secreting plasmablasts derived from a well-characterized cohort of individuals who were at risk of developing RA, based on RA-related serum autoantibody positivity, as compared to patients with early (<1 year) seropositive RA as well as healthy control subjects. The plasmablast antibody repertoires of at-risk subjects were analyzed using DNA barcode-based methods with paired heavy- and light-chain gene sequencing. Cells were single-cell sorted, the cell- and plate-specific DNA barcodes were sequentially added, and next-generation sequencing was performed. Results Total plasmablast levels were similar in the antibody-positive (1%) and control (0.4-1.6%) groups. However, increased frequencies of IgA+ versus IgG+ plasmablasts were observed in the antibody-positive group (39% IgA+ and 37% IgG+) as compared to other groups (1-9% IgA+ and 71-87% IgG+). Paired antibody sequences from antibody-positive subjects revealed cross-isotype clonal families and similar sequence characteristics in the IgA and IgG plasmablast repertoires. Antibody-positive individuals also demonstrated elevated serum levels of IgA isotype anti-cyclic citrullinated peptide 3 antibodies. Conclusion The IgA plasmablast dominance in these antibody-positive individuals suggests that a subset of RA-related autoantibodies may arise from mucosal immune responses and may be involved in early disease pathogenesis in individuals who are at risk of developing RA.

Purpose: There is a comparative lack of concussion incidence data on the new Olympic sport Rugby 7s. This study aimed to determine the incidence (number of concussions per 1000 playing hours [ph]), mean and median severity (days absence), and cause of concussive injuries. Methods: This is a prospective epidemiology study, amateur to elite/national candidate, male (9768) and female (3876) players in USA Rugby sanctioned tournaments, compliant with the international consensus statement for studies in rugby union. Results: Concussions in US Rugby 7s were 7.7/1000 ph (n = 67). Women encountered concussions at 8.1/1000 ph, and men at 7.6/1000 ph (risk ratio [RR] = 1.10, P = 0.593). Elite/national-level players encountered concussions at higher rates (18.3/1000 ph) than lower levels (6.4/1000 ph; RR = 5.48, P < 0.001). Nonelite backs had higher concussive injury rates compared with forwards (7.7/1000 ph; 3.6/1000 ph; RR = 1.28, P = 0.024). Women missed 36.7 d absence from play, meanwhile men missed 27.9 d (P = 0.245). Retrospective history recall reflected previous concussive injuries occurred in 43% of the current study's cohort; of these, 57% encountered multiple concussions within 1 yr. The incidence of repetitive concussions was not statistically different between genders (RR = 1.09, P = 0.754). Most concussions occurred from tackles (63%) and collisions (24%) (P = 0.056). Conclusions: Sports-related concussions occurred with frequency among US amateur Rugby 7s players. US Elite tournament players sustained concussions at much higher rates than international male Rugby 7s counterparts. A substantial portion of US players who sustained a concussion had previous concussion injuries. Given the high rate of concussion, including repetitive concussive injuries, US Rugby 7s may benefit from concussion prevention measures similar to other contact sports such as instruction on proper tackling techniques, in-game and postgame medical assessment, and a standardized return-to-play protocol.

Background: Several factors may mitigate the efficacy of repetitive transcranial magnetic stimulation (rTMS) over sham rTMS in patients with treatment-resistant depression (TRD). These factors include unilateral stimulation (i.e., treatment of only the left dorsolateral prefrontal cortex [DLPFC]), suboptimal methods of targeting the DLPFC and insufficient stimulation intensity (based on coil-to-cortex distance). Methods: We recruited patients with TRD between the ages of 18 and 85 years from a university hospital, and participants were randomized to receive sequential bilateral rTMS (600 pulses at 1 Hz followed by 1500 pulses at 10 Hz), unilateral high-frequency left (HFL)-rTMS (2100 pulses at 10 Hz) or sham rTMS for 3 or 6 weeks depending on treatment response. Stimulation was targeted with MRI localization over the junction of the middle and anterior thirds of the middle frontal gyrus, using 120% of the coil-to-cortex adjusted motor threshold. Our primary outcome of interest was the remission rate. Results: A total of 121 patients participated in this study. The remission rate was significantly higher in the bilateral group than the sham group. The remission rate in the HFL-rTMS group was intermediate and did not differ statistically from the rate in the 2 other groups. There were no significant differences in reduction of depression scores among the 3 groups. Limitations: The number of pulses used per session in the unilateral group was somewhat lower in our trial than in more recent trials, and the sham condition did not involve active stimulation. Conclusion: Our findings suggest that sequential bilateral rTMS is superior to sham rTMS; however, adjusting for coil-to-cortex distance did not yield enhanced efficacy rates. [ABSTRACT FROM AUTHOR]

Background: Anemia during pregnancy is a leading nutritional disorder with serious short- and long-term consequences for both the mother and the fetus. Objective: The objective was to investigate the association between dietary diversity during pregnancy and maternal anemia, low birth weight (LBW), preterm birth (PTB), and stillbirth in rural Ethiopia. Design: We conducted a prospective cohort study and enrolled 432 pregnant women in their first antenatal care visit (24-28 gestational weeks); 374 women completed the follow-up. By using the FAO Women's Dietary Diversity Scores (WDDSs), subjects were categorized into "inadequate" (WDDS <4) and "adequate" (WDDS ≥4) groups and were followed until delivery. Primary outcomes were maternal anemia, birth weight, term delivery, and stillbirth. Results: The attrition rate was 13.7% and was balanced across the 2 groups. The proportion of women consuming dairy, animal-source foods, fruits, and vegetables including vitamin A-rich ones was higher in the adequate than in the inadequate WDDS group (P < 0.05). The overall incidence of maternal anemia increased from 28.6% to 32.4% during the follow-up period. The overall proportion of LBW, PTB, and stillbirth were 9.1%, 13.6%, and 4.5%, respectively. After control for baseline differences, women in the inadequate group had a higher risk of anemia [adjusted RR (ARR: 2.29; 95% CI: 1.62, 3.24], LBW (ARR: 2.06; 95% CI: 1.03, 4.11), and PTB (ARR: 4.61; 95% CI: 2.31, 9.19) but not of stillbirth (ARR: 2.71; 95% CI: 0.88, 8.36) than women in the adequate group (P < 0.05). Conclusions: A WDDS of ≥4 food groups during pregnancy was shown to be associated with lower risk of maternal anemia, LBW, and PTB. Population-based controlled trials of various options to improve dietary diversity are needed before conclusive recommendations can be made. This trial was registered at clinicaltrials.gov as NCT02620943. [ABSTRACT FROM AUTHOR]

Background: Low vitamin B-6 status has been related to increased risk of coronary artery disease (CAD), which is a condition that is associated with inflammation. The most common status marker, plasma pyridoxal 5'-phosphate (PLP), decreases during inflammation; therefore, causal relations are uncertain. Objective: We evaluated the vitamin B-6 biomarkers PLP, pyridoxal, and pyridoxic acid (PA) and the pyridoxic acid:(pyridoxal + PLP) ratio (PAr), a proposed marker of vitamin B-6 catabolism during activated cellular immunity, as predictors of mortality. Design: Associations with risks of long-term all-cause mortality and cardiovascular mortality were evaluated with the use of Cox regression in patients who were undergoing elective coronary angiography for suspected stable angina pectoris (SAP) (n = 4131) and an independent cohort of patients who were hospitalized for acute myocardial infarction (AMI) (n = 3665). Results: Plasma PLP (AMI patients only) and PA predicted all-cause mortality in models that were adjusted for established risk predictors, but associations were attenuated or nonsignificant after additional adjustment for inflammatory markers. PAr was correlated with biomarkers of inflammation (Pearson's r ≥ 0.37) and predicted all-cause mortality and cardiovascular mortality after adjustment for established risk predictors. In SAP patients, PAr had greater predictive strength than did current smoking, diabetes, hypertension, apolipoproteins, or C-reactive protein. PAr provided multiadjusted HRs per SD of 1.45 (95% CI: 1.30, 1.63) and 1.31 (95% CI: 1.21, 1.41) in SAP and AMI patients, respectively. In both cohorts, PAr was a particularly strong predictor of all-cause mortality for patients with no previous CAD history (P-interaction ≤ 0.04). Conclusion: PAr may capture unique aspects of inflammatory activation and thus provide new insights into disease mechanisms that may aid in identifying patients at increased risk of future fatal events.

Background: Urinary tract infections (UTIs) are among the most common bacterial infections and are often treated with antibiotics. Concerns about multidrug-resistant uropathogens have pointed to the need for safe and effective UTI-prevention strategies such as cranberry consumption. Objective: We assessed the effects of the consumption of a cranberry beverage on episodes of clinical UTIs. Design: In this randomized, double-blind, placebo-controlled, multicenter clinical trial, women with a history of a recent UTI were assigned to consume one 240-mL serving of cranberry beverage/ d (n = 185) or a placebo (n = 188) beverage for 24 wk. The primary outcome was the clinical UTI incidence density, which was defined as the total number of clinical UTI events (including multiple events per subject when applicable) per unit of observation time. Results: The dates of the random assignment of the first subject and the last subject's final visit were February 2013 and March 2015, respectively. The mean age was 40.9 y, and characteristics were similar in both groups. Compliance with study product consumption was 98%, and 86% of subjects completed the treatment period in both groups. There were 39 investigator-diagnosed episodes of clinical UTI in the cranberry group compared with 67 episodes in the placebo group (antibiotic use-adjusted incidence rate ratio: 0.61; 95% CI: 0.41, 0.91; P = 0.016). Clinical UTI with pyuria was also significantly reduced (incidence rate ratio: 0.63; 95% CI: 0.40, 0.97; P = 0.037). One clinical UTI event was prevented for every 3.2 woman-years (95% CI: 2.0, 13.1 woman-years) of the cranberry intervention. The time to UTI with culture positivity did not differ significantly between groups (HR: 0.97; 95% CI: 0.56, 1.67; P = 0.914). Conclusion: The consumption of a cranberry juice beverage lowered the number of clinical UTI episodes in women with a recent history of UTI. This study was registered at clinicaltrials.gov as NCT01776021. [ABSTRACT FROM AUTHOR]

Objectives. To evaluate the association between osmophobia and the characteristics of patients and their headaches, among migraine patients. Methods. This was a cross-sectional study. Patients who consecutively sought medical attendance in a primary care unit were asked about their headaches over the last 12 months. Those who had migraine were included. A semi-structured interview, the Headache Impact Test and the Hospital Anxiety and Depression Scale were used. Results. 147 patients had migraine; 78 had osmophobia; 60 had significant anxiety symptoms; and 78 had significant depression symptoms. The mean age of these patients was 43.2 years (± 13.7); 91.2% were women. The mean length of time with complaints of headache was 13.8 years (± 12). Among the migraine patients, those with anxiety, more years of headache history, and phonophobia presented significantly more osmophobia (multivariate logistic regression). Conclusion: Osmophobia in migraine patients is associated with significant anxiety symptoms, length of headache history, and phonophobia. [ABSTRACT FROM AUTHOR]

Background: Chronic migraine is a disabling, under-recognized, and undertreated disorder that increases health burdens. The aim of this study was to evaluate phenotypic features and the relevance of accompanying symptoms of migraine attacks in chronic migraine. Method: This study was conducted as part of an ongoing Turkish Headache Database Study investigating the clinical characteristics and outcomes of headache syndromes in the Turkish population. The electronic database was examined retrospectively, and 835 patients with chronic migraine were included. Results: Patient group consisted of 710 women and 125 men (85 and 15 %, respectively). Mean patient age was 36.8 ± 13.5 years, median value of migraine onset was 60 months (18-120), median headache frequency was 25 days per month (16-30), median of attack duration was 12 h (4-24), and median of intensity was eight (7-9). Increasing headache days per month were inversely related with the presence of nausea, vomiting, phonophobia, and photophobia. Longer duration of headache (months) and higher visual analog scale (VAS) for headache intensity were associated with all accompanying symptoms. Phonophobia, nausea, photophobia, and vomiting were the most frequent accompanying symptoms (experienced by 80.2, 77.6, 71.2, and 40.9 % of patients, respectively). Osmophobia was also frequent in chronic migraine patients (53.4 %) and was closely associated with other accompanying symptoms. Vertigo and dizziness were observed less frequently, and they were not associated with accompanying symptoms. Conclusion: Phenotype of chronic migraine may be associated with the course of chronification. Duration of illness and attack intensity were closely related with the presence of accompanying symptoms, although headache frequency was found to be inversely related to the presence of accompanying symptoms. Osmophobia was also a frequent symptom and was closely related with other accompanied symptoms, unlike vertigo and dizziness. Inclusion of osmophobia into the diagnostic criteria might improve accurate diagnosis of chronic migraine. [ABSTRACT FROM AUTHOR]

Background: The utility of dairy ingredients in the supplementary foods used in the treatment of childhood moderate acute malnutrition (MAM) remains unsettled. Objective: We evaluated the effectiveness of a peanut-based ready-to-use supplementary food (RUSF) with soy protein compared with a novel RUSF containing dairy ingredients in the form of whey permeate and whey protein concentrate in the treatment of children with MAM. Design: We conducted a randomized, double-blind clinical effectiveness trial involving rural Malawian and Mozambican children 6-59 mo of age with MAM treated with either soy RUSF or a novel whey RUSF treatment of ~75 kcal ⋅ kg-1 ⋅ d-1 for up to 12 wk. Results: The proportion of children that recovered from MAM was significantly higher in the group that received whey RUSF (960 of 1144; 83.9%) than in the group that received soy RUSF (874 of 1086; 80.5%; P, 0.04; risk difference 3.4%, 95% CI: 0.3%, 6.6%). Children who consumed whey RUSF also demonstrated better growth markers, with a higher mean midupper arm circumference (MUAC) at the time of discharge (P < 0.009), greater MUAC gain during the course of treatment (P < 0.003), higher mean weight-for-height z score at discharge (P < 0.008), and greater weight gain (P < 0.05). No significant differences were identified in length gain or time to recovery between the 2 groups. Conclusion: This study highlights the importance of milk protein in the treatment of MAM, because the use of a novel whey RUSF resulted in higher recovery rates and improved growth than did soy RUSF, although the whey RUSF supplement provided less total protein and energy than the soy RUSF. This study was registered at clinicaltrials.gov as NCT01790048. [ABSTRACT FROM AUTHOR]

Background. A multidimensional geriatric assessment (GA) is recommended in older cancer patients to inventory health problems and tailor treatment decisions accordingly but requires considerable time and human resources. The G8 is among the most sensitive screening tools for selecting patients warranting a full GA but has limited specificity. We sought to develop and validate an optimized version of the G8. Patients and Methods. We used a prospective cohort of cancer patients aged ≥70 years referred to geriatricians for GA (2007-2012: n = 729 [training set]; 2012-2014: n = 414 [validation set]). Abnormal GA was defined as at least one impaired domain across seven validated tests. Multiple correspondence analysis, multivariate logistic regression, and bootstrapped internal validation were performed sequentially. Results. The final model included six independent predictors for abnormal GA: weight loss, cognition/mood, performance status, self-rated health status, polypharmacy (≥6 medications per day), and history of heart failure/coronary heart disease. For the original G8, sensitivity was 87.2% (95% confidence interval, 84.3-89.7), specificity 57.7% (47.3-67.7), and area under the receiver-operating characteristic curve (AUROC) 86.5% (83.5-89.6). The modified G8 had corresponding values of 89.2% (86.5-91.5), 79.0% (69.4-86.6), and 91.6% (89.3; 93.9), with higher AUROC values for all tumor sites and stable properties on the validation set. Conclusion. A modified G8 screening tool exhibited better diagnostic performance with greater uniformity across cancer sites and required only six items. If these features are confirmed in other settings, the modified tool may facilitate selection for a full GA in older patients with cancer. [ABSTRACT FROM AUTHOR]

Patients with a history of substance use disorder (SUD) are more likely to be prescribed opioid medications for chronic pain than patients without an SUD history; however, little is known about prescription opioid therapy in populations composed exclusively of patients with SUD. This study examined correlates of prescription opioid therapy in 214 Veterans with chronic noncancer pain and an SUD history. Participants completed psychosocial questionnaires and participated in a structured mental health diagnostic interview, and medical diagnoses and opioid pharmacy data were abstracted from their Department of Veterans Affairs electronic medical records. Participants were categorized into three groups based on opioid prescriptions in the past 90 d: no opioid therapy (n = 134), short-term (<90 d) opioid therapy (n = 31), or long-term (>/= 90 d) opioid therapy (n = 49). Relative to participants prescribed no or short-term opioid therapy, participants who were prescribed long-term opioid therapy had a greater number of pain diagnoses; reported higher levels of pain severity, interference, and catastrophizing; and endorsed lower chronic pain self-efficacy. In a multivariate model, number of pain diagnoses and pain interference were associated with a greater likelihood of being prescribed long-term opioid therapy after controlling for demographic and clinical characteristics. Findings highlight the poor pain-related functioning in patients with SUD histories who are prescribed long-term opioid therapy. [ABSTRACT FROM AUTHOR]

Background: Observational data have suggested that intakes of nutrients involved in one-carbon metabolism are inversely associated with risk of colorectal carcinoma and adenomas. In contrast, results from some preclinical studies and cardiovascular and chemoprevention trials have raised concerns that high folate intake may promote carcinogenesis by facilitating the progression of established neoplasia. Objective: We tested the hypothesis that higher total folate intake (including food folate and folic acid from fortified foods and supplements) or other one-carbon nutrient intakes might be associated with poorer survival after a diagnosis of colorectal cancer. Design: We used rectal and colon cancer cases within the following 2 US prospective cohort studies: the Nurses' Health Study and the Health Professionals Follow-Up Study. Biennial questionnaires were used to gather information on medical history and lifestyle factors, including smoking and alcohol consumption. B-vitamin and methionine intakes were derived from food-frequency questionnaires. Data on tumor molecular characteristics (including microsatellite instability, CpG island methylator phenotype, KRAS, BRAF, and PIK3CA mutations, and long interspersed nucleotide element 1 methylation level) were available for a subset of cases. We assessed colorectal cancer-specific mortality according to postdiagnostic intakes of one-carbon nutrients with the use of multivariable Cox proportional hazards regression models. Results: In 1550 stage I--III colorectal cancer cases with a median follow-up of 14.9 y, we documented 641 deaths including 176 colorectal cancer-specific deaths. No statistically significant associations were observed between postdiagnostic intakes of folate or other one-carbon nutrients and colorectal cancer-specific mortality (multivariate P-trend ≥ 0.21). In an exploratory molecular pathologic epidemiology survival analysis, there was no significant interaction between one-carbon nutrients or alcohol and any of the tumor molecular biomarkers examined. Conclusions: Higher postdiagnostic intakes of one-carbon nutrients are not associated with the prognosis in stage I--III colorectal cancer. Our findings do not support the hypothesis that higher folate intake after colorectal cancer diagnosis might increase risk of cancer-related death. [ABSTRACT FROM AUTHOR]

Background: Experimental evidence has suggested that vitamin D may be protective against tobacco-related cancers through the inhibition of the formation of tumors induced by tobacco carcinogens. To our knowledge, only one previous epidemiologic study investigated the association between vitamin D status and tobacco-related cancer risk, and no study has focused on vitamin D-related gene polymorphisms. Objective: Our objective was to prospectively study the association between plasma 25-hydroxyvitamin D [25(OH)D] concentrations, vitamin D-related gene polymorphisms, and risk of tobacco-related cancers. Design: A total of 209 tobacco-related cancers were diagnosed within the SU.VI.MAX (Supplémentation en vitamines et minéraux antioxydants) cohort (1994-2007) and were matched with 418 controls as part of a nested case-control study. Tobacco-related cancers (i.e., cancers for which tobacco is one of the risk factors) included several sites in the respiratory, digestive, reproductive, and urinary systems. Total plasma 25(OH)D was assessed with the use of an electrochemolumi-nescent assay. Polymorphisms were determined with the use of a Taq-Man assay. Conditional logistic regression models were computed. Results: A 25(OH)D concentration ≥30 ng/mL was associated with reduced risk of tobacco-related cancers (OR for ≥30 compared with <30 ng/mL: 0.59; 95% CI 0.35, 0.99; P = 0.046). This association was observed in former and current smokers (OR for ≥30 compared with <30 ng/mL: 0.43; 95% CI: 0.23, 0.84; P = 0.01) but not in never smokers (P = 0.8). The vitamin D receptor (VDR) FokI AA genotype and retinoid X receptor (RXR) rs7861779 TT genotype were associated with increased risk of tobacco-related cancers [OR for homozygous mutant type (MT) compared with wild type (WT): 1.87; 95% CI: 1.08, 3.23; P-trend = 0.02; OR for heterozygous type (HT) plus MT compared with WT: 1.60; 95% CI: 1.07, 2.38; P = 0.02]. Conclusions: In this prospective study, high vitamin D status [25(OH)D concentration ≥30 ng/mL] was associated with decreased risk of tobacco-related cancers, especially in smokers. These results, which are supported by mechanistic plausibility, suggest that vitamin D may contribute to the prevention of tobacco-induced cancers in smokers and deserve additional investigation. The SU.VI.MAX trial was registered at clinicaltrials.gov as NCT00272428. [ABSTRACT FROM AUTHOR]

Background: In utero latent iron deficiency has been associated with abnormal neurodevelopmental outcomes during childhood. Its concomitant effect on auditory neural maturation has not been well studied in late preterm and term infants. Objective: The objective was to determine whether in utero iron status is associated with auditory neural maturation in late preterm and term infants. Design: This prospective cohort study was performed at Sir Ganga Ram Hospital, New Delhi, India. Infants with a gestational age ≥34 wk were eligible unless they met the exclusion criteria: craniofacial anomalies, chromosomal disorders, hemolytic disease, multiple gestation, third-trimester maternal infection, chorioamnionitis, toxoplas-mosis, other infections, rubella, cytomegalovirus infection, and herpes simplex virus infections (TORCH), Apgar score < 5 at 5 min, sepsis, cord blood not collected, or auditory evaluation unable to be performed. Sixty consecutive infants with risk factors for iron deficiency, such as small for gestational age and maternal diabetes, and 30 without risk factors for iron deficiency were enrolled. Absolute wave latencies and interpeak latencies, evaluated by auditory brainstem response within 48 h after birth, were measured and compared between infants with latent iron deficiency (serum ferritin ≤75 ng/mL) and infants with normal iron status (serum ferritin >75 ng/mL) at birth. Results: Twenty-three infants had latent iron deficiency. Infants with latent iron deficiency had significantly prolonged wave V latencies (7.10 6 0.68 compared with 6.60 6 0.66), III-V interpeak latencies (2.37 6 0.64 compared with 2.07 6 0.33), and I-V interpeak latencies (5.10 6 0.57 compared with 4.72 6 0.56) compared with infants with normal iron status (P < 0.05). This difference remained significant on regression analyses after control for confounders. No difference was noted between latencies I and III and interpeak latencies I III. Conclusion: Latent iron deficiency is associated with abnormal auditory neural maturation in infants at ≥34 wk gestational age. This trial was registered at clinicaltrials.gov as NCT02503397.

Background: Mandatory fortification, prevalent supplement use, and public health guidelines recommending periconceptional supplementation have increased folic acid intakes in North American pregnant women. However, the effects of increased folic acid intakes during pregnancy on maternal and cord blood folate concentrations have not been well established. Objectives: In this prospective study, we determined maternal and cord blood concentrations of folate and unmetabolized folic acid (UMFA) in a cohort of pregnant Canadian women and their newborns and examined the effect of maternal intakes of folate and folic acid and fetal genetic variants in folate metabolism on folate status. Design: Folate and folic acid intakes of 368 Canadian pregnant women were assessed in early (0-16 wk) and late (23-37 wk) pregnancy. Blood concentrations of folate and UMFAwere measured with the use of immunoassays and liquid chromatography-mass spectrometry, respectively, in maternal samples in early pregnancy (12-16 wk), at delivery (28-42 wk), and in cord blood. Four fetal genetic variants of the 5,10-methylenetetrahydrofolate reductase (MTHFR) and dihydrofolate reductase (DHFR) genes were assessed for their association with cord blood concentrations of folate and UMFA. Results: Geometric mean (95% CI) maternal red blood cell (RBC) folate concentrations were 2417 nmol/L (2362, 2472 nmol/L ) and 2793 nmol/L (2721, 2867 nmol/L ) in early pregnancy and at delivery, respectively. The mean (95% CI) cord RBC folate concentration was 2689 nmol/L (2614, 2765 nmol/L). UMFA was detectable in .90% of maternal and cord plasma samples. Although 3 fetal MTHFR and DHFR genetic variants had no effect, the fetal MTHFR 677TT genotype was associated with significantly lower cord serum (P = 0.03) and higher cord RBC (P = 0.02) folate concentrations than those of the wild type. Conclusions: Notwithstanding differences in assays, maternal and cord RBC folate and plasma UMFA concentrations were higher than previously reported values. Functional ramifications of high folate and UMFA concentrations in maternal and fetal circulation warrant additional investigation because an excess folate status may affect long-term health outcomes of the offspring. This study was registered at www.clinicaltrials.gov as NCT02244684. [ABSTRACT FROM AUTHOR]

Background: Considering the suggested link between vitamin D insufficiency and several chronic diseases, attention should be given to approaches for improving vitamin D status. Elderly subjects are regarded as a high-risk group for developing an insufficient vitamin D status. Socioeconomic, dietary, lifestyle and environmental factors are considered as influencing factors, whereupon sex differences in predictors of vitamin D status are rarely investigated. The purpose of this study is to identify the main predictors of serum 25-hydroxyvitamin D3 [25(OH)D3] concentrations in elderly subjects by taking into account potential sex differences. Methods: This is a cross-sectional study in 162 independently living German elderly aged 66 to 96 years. Serum 25(OH)D3 concentrations were assessed by an electrochemiluminescence immunoassay. Multiple regression analyses were performed to identify predictors of 25(OH)D3 concentrations stratified by sex. Results: Median 25(OH)D3 concentration was 64 nmol/L and none of the subjects had 25(OH)D3 concentrations < 25 nmol/L. In women, intact parathyroid hormone (iPTH) (β = -0.323), % total body fat (β = -0.208), time spent outdoors (β = 0.328), month of blood sampling (β = 0.229) and intake of vitamin D supplements (β = 0.172) were the predominant predictors of 25(OH)D3, whereas in men, iPTH (β = -0.254), smoking (β = -0.282), physical activity (β = 0.336) and monthly household net income (β = 0.302) predicted 25 (OH)D3 concentrations. The final regression models accounted for 30% and 32% of the variance in 25(OH)D3 concentrations in women and men, respectively. Conclusion: The findings indicate that 25(OH)D3 concentrations are influenced by body composition, month of blood sampling, economic factors, lifestyle, supplement intake and iPTH, but may not be associated with age, sex, dietary factors, kidney function and presence of selected chronic diseases in community-dwelling elderly. Furthermore, our results provide evidence for sex-specific determinants of the vitamin D status, which ought to be considered for preventive strategies. [ABSTRACT FROM AUTHOR]

BACKGROUND: Polyunsaturated fatty acids (PUFAs) may play a role in fracture, but studies have been largely confined to estimates of dietary intake. OBJECTIVE: We aimed to examine associations between fatty acids measured in late life and fish-oil consumption in early life, midlife, and late life with osteoporotic fracture risk. DESIGN: Osteoporotic fractures were determined from medical records over 5-9 y of follow-up in men and women aged 66-96 y. Data were analyzed from 1438 participants including 898 participants who were randomly selected from the Age, Gene/Environment Susceptibility Study, which is an observational study, and 540 participants with incident fracture. Plasma phospholipid fatty acids were assessed by using gas chromatography. Fish-oil consumption was assessed by using validated questionnaires as never (referent), less than daily, or daily. HRs and 95% CIs adjusted for age, education, height, weight, diabetes, physical activity, and medications were estimated by using Cox regression. RESULTS: In men, the highest tertile of PUFAs, n-3 (ω-3), and eicosapentaenoic acid were associated with decreased fracture risk [HRs (95% CIs): 0.60 (95% CI: 0.41, 0.89), 0.66 (0.45, 0.95), and 0.59 (0.41, 0.86), respectively]. In women, PUFAs tended to be inversely associated with fracture risk (P-trend = 0.06), but tertiles 2 and 3 were not independently associated with risk. Tertile 2 of n-6 and arachidonic acid was associated with fracture risk in women [HRs (95% CIs): 1.43 (1.10, 1.85) and 1.42 (1.09, 1.85), respectively]. Daily fish-oil consumption in late life was associated with lower fracture risk in men (HR: 0.64; 95% CI: 0.45, 0.91). Daily fish-oil consumption in midlife was associated with lower fracture risk in women (HR: 0.75; 95% CI: 0.58, 0.98). CONCLUSIONS: Greater PUFA concentrations may be associated with lower osteoporotic fracture risk in older adults, particularly in men. Critical time periods for n-3 fatty acid consumption may differ by sex. [ABSTRACT FROM AUTHOR]

Background. We conducted this prospective, randomized, double-blind, placebo-controlled study to evaluate the effects of transcutaneous electric acupoint stimulation (TEAS) on the quality of recovery (QoR) and postoperative analgesia after gynecological laparoscopic surgery. Methods. 74 American Society of Anesthesiologists physical status (ASA) I or II patients undergoing gynecological laparoscopic surgery were randomly allocated to TEAS or control groups. The primary outcome was the quality of recovery, which was assessed on the day before surgery and 24 h after surgery using a 40-item questionnaire. Secondary outcomes included postoperative pain scores, the incidence of postoperative nausea and vomiting (PONV), duration of postanesthesia care unit (PACU) stay, and patient's satisfaction. Results. The TEAS group had higher QoR scores than control group upon 24 h after surgery (177 versus 165; P < 0.001). Compared with the control group, postoperative pain scores and the cumulative number of opioids administered were lower in the TEAS group patients (P = 0.04). TEAS reduced the incidence of PONV and dizziness, as well as duration of PACU stay. Simultaneously, the patient's satisfaction scores were higher in the TEAS group (P = 0.002). Conclusion. Preoperative TEAS enhances QoR, improves postoperative analgesia and patient's satisfaction, alleviates postoperative side effects, and accelerates discharge after general anesthesia for gynecological laparoscopic surgery.

Background: Unlike experimental results, epidemiologic studies that used dietary questionnaires were not convincing as regards the relations between dietary fatty acids (FAs) and risk of colorectal cancer (CRC). The FA composition of adipose tissue, which is considered to be an indicator of dietary intake over 2-3 y because of the slow turnover rate, appears promising but has so far been rarely used to explore the relation between CRC and exogenous or endogenously produced FAs. Objective: In this case-control study, we aimed to investigate associations between risk of CRC and the FA composition of subcutaneous adipose tissue and product-to-precursor ratios as indexes of enzymatic activities. Design: From 2008 to 2011, we recruited 203 cases with newly diagnosed CRC and elective surgery with a curative intent and 223 control subjects with planned abdominal surgery for benign disease and no history of CRC or polyp resection. During surgery, abdominal subcutaneous adipose tissue samples were optimally collected, stored, and analyzed by using high-performance gas chro-matography. Multivariate logistic regression was used to estimate ORs for CRC in relation to individual FAs divided into tertiles according to the FA distribution in controls. Results: After adjustment, significant positive associations with CRC risk were observed in highest compared with lowest tertiles of 16:1n-9 (OR: 1.75; 95% CI: 1.00, 3.06; P-trend = 0.045), 20:3n-6 (OR: 1.79; 95% CI: 1.01, 3.17; P-trend = 0.038), 22:5n-3 (OR: 1.82; 95% CI: 1.06, 3.12; P-trend = 0.023), and the ratio of 18:2n-6 to 18:3n-3 (OR: 2.34; 95% CI: 1.37, 3.98; P-trend = 0.001). Significant inverse associations were observed for 18:3n-3 (OR: 0.48; 95% CI: 0.29, 0.81; P-trend = 0.007). Several product-to-precursor ratios showed significant differences between cases and controls in particular ratios that reflected elongase 2/5 activity. Conclusions: CRC patients presented higher concentrations of some FAs but lower concentrations of a-linolenic acid in their subcutaneous adipose tissue than did controls. These results may reflect both dietary patterns and altered FA metabolism but require mechanistic explorations. This study was registered at clinicaltrials.gov as NCT01966081. [ABSTRACT FROM AUTHOR]

Background: In obstructive uropathy, despite a severe increase in the serum creatinine (Cr) levels, only a mild cystatin C (CysC) increase was previously reported. Therefore, we aimed to determine the availability of serum Cr/CysC ratio in predicting postrenal acute kidney injury (AKI). Materials and Methods: This was a cross-sectional study involving 61-adult patients with heterogeneous AKI cases. Patients with bilateral pelvicalyceal dilatation in renal sonography were considered as postrenal AKI group (n = 15) and others were intrinsic AKI group (n = 46). Venous blood sampling for blood urea nitrogen, Cr and CysC measurements were performed on admission. Results: The mean age of study population was 66.3 ± 15.5 years; 38 (62%) of which were male. Two groups were similar regarding age, gender, and comorbidities. Cr/CysC ratio was significantly higher in postrenal AKI group (6.9 ± 3.1 vs. 4.4 ± 2.1, P = 0.007). Conclusion: We suggest that serum Cr/CysC ratio seems to be a useful diagnostic tool for detection of postrenal AKI cases, especially for the cases without definite hydronephrosis.

The modification of microbiota composition to a ‘beneficial’ one is a promising approach for improving intestinal as well as overall health. Natural fibres and phytochemicals that reach the proximal colon, such as those present in various nuts, provide substrates for the maintenance of healthy and diverse microbiota. The effects of increased consumption of specific nuts, which are rich in fibre as well as various phytonutrients, on human gut microbiota composition have not been investigated to date. The objective of the present study was to determine the effects of almond and pistachio consumption on human gut microbiota composition. We characterised microbiota in faecal samples collected from volunteers in two separate randomised, controlled, cross-over feeding studies (n 18 for the almond feeding study and n 16 for the pistachio feeding study) with 0, 1·5 or 3 servings/d of the respective nuts for 18 d. Gut microbiota composition was analysed using a 16S rRNA-based approach for bacteria and an internal transcribed spacer region sequencing approach for fungi. The 16S rRNA sequence analysis of 528 028 sequence reads, retained after removing low-quality and short-length reads, revealed various operational taxonomic units that appeared to be affected by nut consumption. The effect of pistachio consumption on gut microbiota composition was much stronger than that of almond consumption and included an increase in the number of potentially beneficial butyrate-producing bacteria. Although the numbers of bifidobacteria were not affected by the consumption of either nut, pistachio consumption appeared to decrease the number of lactic acid bacteria (P< 0·05). Increasing the consumption of almonds or pistachios appears to be an effective means of modifying gut microbiota composition. [ABSTRACT FROM PUBLISHER]

Background: Determining the appropriate disposition of emergency department (ED) syncope patients is challenging. Previously developed decision tools have poor diagnostic test characteristics and methodological flaws in their derivation that preclude their use. We sought to develop a scale to risk-stratify adult ED syncope patients at risk for serious adverse events (SAEs) within 30 days. Methods: We conducted a medical record review to include syncope patients age ≥ 16 years and excluded patients with ongoing altered mental status, alcohol or illicit drug use, seizure, head injury leading to loss of consciousness, or severe trauma requiring admission. We collected 105 predictor variables (demographics, event characteristics, comorbidities, medications, vital signs, clinical examination findings, emergency medical services and ED electrocardiogram/monitor characteristics, investigations, and disposition variables) and information on the occurrence of predefined SAEs. Univariate and multiple logistic regression analyses were performed. Results: Among 505 enrolled patient visits, 49 (9.7%) suffered an SAE. Predictors of SAE and their resulting point scores were as follows: age ≥ 75 years (1), shortness of breath (2), lowest ED systolic blood pressure < 80 mm Hg (2), Ottawa Electrocardiographic Criteria present (2), and blood urea nitrogen > 15 mmol/L (3). The final score calculated by addition of the individual scores for each variable (range 0- 10) was found to accurately stratify patients into low risk (score < 1, 0% SAE risk), moderate risk (score 1, 3.7% SAE risk), or high risk (score > 1, ≥ 10% SAE risk). Conclusion: We derived a risk scale that accurately predicts SAEs within 30 days in ED syncope patients. If validated, this will be a potentially useful clinical decision tool for emergency physicians, may allow judicious use of health care resources, and may improve patient care and safety.

Background. Exercise has been suggested to be a viable treatment for depression. This study investigates the effect of supervised aerobic exercise training on depressive symptoms and physical performance among Chinese patients with mild to moderate depression in early in-patient phase. Methods. A randomized repeated measure and assessor-blinded study design was used. Subjects in aerobic exercise group received 30 minutes of aerobic training, five days a week for 3 weeks. Depressive symptoms (MADRS and C-BDI) and domains in physical performance were assessed at baseline and program end. Results. Subjects in aerobic exercise group showed a more significant reduction in depressive scores (MADRS) as compared to control (between-group mean difference = 10.08 ± 9.41; p = 0.026) after 3 weeks training. The exercise group also demonstrated a significant improvement in flexibility (between group mean difference = 4.4 ± 6.13; p = 0.02). Limitations. There was lack of longitudinal followup to examine the long-term effect of aerobic exercise on patients with depression. Conclusions. Aerobic exercise in addition to pharmacological intervention can have a synergistic effect in reducing depressive symptoms and increasing flexibility among Chinese population with mild to moderate depression. Early introduction of exercise training in in-patient phase can help to bridge the gap of therapeutic latency of antidepressants during its nonresponse period. [ABSTRACT FROM AUTHOR]

Background: Obstetric complications have predicted future development of schizophrenia in previous studies, but they are also more common in mothers with schizophrenia. The aims of this study were to compare the occurrence of obstetric complications in children of mothers with schizophrenia spectrum psychoses and control children, and to investigate whether obstetric complications predicted children’s psychiatric morbidity. Method: The Helsinki High-Risk (HR) Study monitors females born between 1916 and 1948 and treated for schizophrenia spectrum disorders in Helsinki psychiatric hospitals, their offspring born between 1941 and 1977, and controls. We examined information on obstetric complications and neonatal health of 271 HR and 242 control offspring. We compared the frequency of obstetric complications and neonatal health problems in the HR group vs controls and in HR children who later developed psychotic disorders vs healthy HR children. A Cox regression model was used to assess whether problems in pregnancy or delivery predicted psychiatric morbidity within the HR group. Results: Few differences between HR and control offspring were found in obstetric complications. Within the HR group, infections (hazard rate ratio [HRR] 3.73, 95% CI 1.27–11.01), hypertension during pregnancy (HRR 4.10, 95% CI 1.15–14.58), and placental abnormalities (HRR 4.09, 95% CI 1.59–10.49) were associated with elevated risk of schizophrenia spectrum psychoses. Conclusions: Common medical problems during pregnancy were associated with increased risk of schizophrenia spectrum psychoses in offspring of mothers with schizophrenia spectrum psychoses. These results underline the role of the prenatal period in the development of schizophrenia and the importance of careful monitoring of pregnancies of mothers with psychotic disorder.

Context.-Prostate cancer (PC) with lymph node metastases (LN+) is relatively rare, whereas it is relatively common in disease with a Gleason score (GS) 8 to 10 and virtually never seen in PC with GS 6 or less. It is most variable in GS 7 PC. Objective.-To determine clinicopathologic features associated with GS 7 PC with LN+ compared with a control group without lymph node metastases (LN-). Design.-We analyzed 184 GS 7 radical prostatectomies with LN+ and the same number of LN- Gleasonmatched controls. The LN+ cases were GS 3+4=7 (n=64; 34.8%), GS 4 + 3 = 7 (n ¼ 66; 35.9%), GS 3 + 4 = 7 with tertiary 5 (n = 10; 5.4%), and GS 4 + 3 = 7 with tertiary 5 (n = 44; 23.9%). Results.-The LN+ cases demonstrated higher average values in preoperative prostate-specific antigen (12.2 versus 8.1 ng/mL), percentage of positive biopsy cores (59.1% versus 42.9%), prostate weight (54.4 versus 49.4 g), number of LNs submitted (12.7 versus 9.4), incidence of nonfocal extraprostatic extension (82.6% versus 63.6%), tumor volume (28.9% versus 14.8%), frequency of lymphovascular invasion (78.3% versus 38.6%), intraductal spread of carcinoma (42.4% versus 20.7%), incidence of satellite tumor foci (16.4% versus 4.3%), incidence of pT3b disease (49.5% versus 14.7%), and lymphovascular invasion in the seminal vesicles (52% versus 30%). There were differences in GS 4 patterns and cytology between LN+ and LN- cases, with the former having higher volumes of cribriform and poorly formed patterns, larger nuclei and nucleoli, and more-frequent macronucleoli. All P ≤ .05. Conclusion.-Gleason score 7 PC with LN+ has features highlighting a more-aggressive phenotype. These features can be assessed as prognostic markers in GS 7 disease on biopsy (eg, GS 4 pattern, intraductal spread, cytology) or at radical prostatectomies (all variables), even in men without LN dissection or LN- disease.

Introduction: Fournier's gangrene is a rare, rapidly progressive, necrotizing fasciitis of the external genitalia and perineum. Case series have shown a mortality rate of 20% to 40% with an incidence of as high as 88% in some reports. In this study we aimed to share our experience in the management of Fournier's gangrene and to identify risk factors that affect mortality. Methods: The medical records of 50 patients with Fournier's gangrene who presented at the University Hospital Hassan II of Fez from January 2003 to December 2009 were reviewed retrospectively to analyze the outcome and identify the risk factors and prognostic indicators of mortality. Results: Ten males and five females were enrolled in the study. The mean age was 54 years (range 23-81). The most common predisposing factor was diabetes mellitus (34%). E. coli was the most frequent bacterial organisms cultured. All patients were treated with a common approach of resuscitation, broad-spectrum antibiotics, and wide surgical excision. The mortality rate was 24%. The advanced age, renal failure on admission, extension of infection to the abdominal wall, occurrence of septic shock and need for postoperative mechanical ventilation are the main prognostic factors of mortality. In multivariate analysis, none of these variables is an independent predictor of mortality. Conclusions: Fournier's gangrene is still a very severe disease with high mortality rates. Early recognition of infection associated with invasive and aggressive treatment is essential for attempting to reduce these prognostic indices. [ABSTRACT FROM AUTHOR]

Context.--Human telomerase reverse transcriptase (hTERT), an enzyme that enables cells to overcome replicative senescence and to divide indefinitely, is overexpressed in many cancers and their precursor lesions. Objective.--To test whether hTERT expression is related to neoplastic progression and resistance to apoptosis in vulvar epithelia. Design.--Immunoexpression of hTERT was evaluated in 101 formalin-fixed, paraffin-embedded archival vulvar epithelia consisting of normal squamous vulvar epithelia (n = 25), lichen sclerosus (n = 10), high-grade classic vulvar intraepithelial neoplasia (n = 16), differentiated vulvar intraepithelial neoplasia (n = 18), and vulvar invasive keratinizing squamous cell carcinoma (n = 32) and related to survivin and p53 expression. Immunostaining for all factors was scored for moderate and strong intensities with regard to quantity to determine upregulation and overexpression (score 0, 0% immunoreactive cells; score 1+, <5% immunoreactive cells; score 2+, 5% to 50% immunoreactive cells; score 3+, >50% immunoreactive cells). Score 3+ was considered as overexpression. Results.--Nuclear hTERT immunoexpression was closely related to survivin reactivity, increased from normal vulvar squamous epithelia to lichen sclerosus and to high-grade classic vulvar intraepithelial neoplasia, differentiated vulvar intraepithelial neoplasia, and invasive keratinizing squamous cell carcinoma (P < .001), and followed the morphologic distribution of atypical squamous epithelial cells. Overexpression of hTERT was comparable to that seen for p53 in invasive keratinizing squamous cell carcinoma (P = .62); significant differences were calculated for differentiated vulvar intraepithelial neoplasia (P = .003) and high-grade classic vulvar intraepithelial neoplasia (P = .001). Conclusion.--Human telomerase reverse transcriptase is upregulated in vulvar intraepithelial neoplasia and invasive keratinizing squamous cell carcinoma compared with nonneoplastic squamous epithelia of the vulva as an apparently early and preinvasive event in the neoplastic transformation, with development of cellular longevity and resistance to apoptosis by survivin activation as associated features, independent of the etiology of vulvar intraepithelial neoplasia.

The overall goal of this observational study was to determine the type and prevalence of colonoscopic lesions encountered in veterans with traumatic spinal cord injury (SCI) and to examine their relationship to lesion level, completeness, and duration postinjury. We retrospectively reviewed the electronic charts of veterans with SCI who are regularly followed in our SCI clinic. Colonoscopy in veterans with SCI was undertaken for their gastrointestinal (GI) complaints. Of the 87 veterans with SCI, 71 who were 50 years of age or older were included in this study. Of these 71, 28 underwent colonoscopies (39.4%). Demographic variables were matched between patients who underwent colonoscopies and those who did not for age, sex, race/ethnicity, age of onset of SCI, and duration of SCI (p > 0.05). The colonoscopic lesions seen in 26 (93%) of the 28 veterans with SCI who underwent colonoscopies included diverticulae, internal hemorrhoids, and polyps. No relationship was found between colonoscopic lesion type and SCI lesion location or severity. A relationship was found between total colonoscopic lesions and duration of SCI (p < 0.001). Age-, sex-, and race/ethnicity-matched veterans without SCI (controls) who underwent colonoscopy for their GI complaints had more colonoscopic lesions than the veterans with SCI who underwent colonoscopies (p < 0.001).

Background. Evidence-based stroke care should be available to all patients. However, evidence exists of inequalities according to age. This study compared access to care for younger adults to that for over 65s. Methods. Using population-based data from 4229 patients with first-ever stroke between 1995 and 2010, associations between age and 21 care indicators were investigated using multivariable logistic regression. Results. Age was not associated with stroke unit admission for ischaemic stroke (P = 0.666). Younger PICH patients were least likely to be admitted to stroke units (P = 0.001), instead treated on neurosurgical or ICU wards. Younger age was also associated with admission to neurosurgery or ICU after SAH (P = 0.006), increased occupational or physiotherapy at 1 year (P = 0.043), and contact with a GP 3 months after stroke (P < 0.001). Conclusion. Younger patients have equal or greater access to evidence-based care. However, there is a need to ensure that services meet the needs of this group. [ABSTRACT FROM AUTHOR]

Guidelines do not include cerebral oximetry among monitoring for carotid endarterectomy (CEA). The purpose of this study was to evaluate the reliability of near-infrared spectroscopy (NIRS) in the detection of clamping ischemia and in the prevention of clamping-related neurologic deficits using, as a cutoff for shunting, a 20% regional cerebral oxygen saturation (rSO2) decrease if persistent more than 4minutes, otherwise a 25% rSO2 decrease. Bilateral rSO2 wasmonitored continuously in patients undergoing CEA under general anesthesia (GA). Data was recorded after clamping, declamping, during shunting and lowest values achieved. Preoperative neurologic, CT-scan, and vascular lesions were recorded. We reviewed 473 cases: 305 males (64.5%) mean age 73.3 ± 7.3. Three patients presented transient ischemic deficits at awakening, no perioperative stroke or death; 41 (8.7%) required shunting: 30 based on the initial rSO2 value and 11 due to a decrease during surgery. Using the ROC curve analysis we found, for a > 25% reduction from baseline value, a sensitivity of 100% and a specificity of 90.6%. Reliability, PPV, and NPV were 95.38%, 9%, and 100%, respectively. In conclusion, this study indicates the potential reliability of NIRS monitoring during CEA under GA, using a cutoff of 25% or a cutoff of 20% for prolonged hypoperfusion. [ABSTRACT FROM AUTHOR]

Purpose: To provide a quantative analysis of postlobectomy chest radiographic changes and to evaluate whether the scarring from prior sternotomy affects the size of the hemithorax and the duration of air leak in patients with subsequent lobectomy. Methods In this retrospective case-controlled series, 10 consecutive patients who had a lobectomy after a prior sternotomy and 30 controls, 3 for each case, matched for lobectomy site were identified. Pre- and postoperative chest radiographs were quantitatively analysed for diaphragmic elevation, size of each hemithorax, mediastinal shift, and the presence of pneumothorax. Charts were reviewed for air-leak duration, surgical complications, and duration of hospitalization. Results There was no difference between patients with lobectomy and with and without prior sternotomy for the following variables expressed as mean (SD): hemidiaphragm elevation (1.5 ± 2.5 vs 0.5 ± 2.0 cm; P = .2), change of hemithorax size (mean transverse, 0.99 ± 0.05 vs 0.97 ± 0.07; P = .5; craniocaudal, 0.93 ± 0.08 vs 0.91 ± 0.08; P = .4) and mediastinal shift (upper, 1.2 ± 0.4 vs 1.3 ± 0.6; P = .5; lower, 1.2 ± 0.4 vs 1.2 ± 0.3; P = .8), the latter 2 were expressed as the ratio of post- to preoperative measurements. These postlobectomy radiographic findings varied, depending on the resected lobe, and became progressively more pronounced during the first 12 months after surgery. There was no difference in pneumothorax duration (mean [SD]) (9.5 ± 21 days vs 6.4 ± 7.5 days; P = .5), air leak duration (mean [SD]) (0.7 ± 0.8 days vs 1.3 ± 3.9 days; P = .6), complication rate (20% vs 30%; P = .5), or hospital stay (mean [SD]) (6.0 ± 1.7 days vs 6.9 ± 4.7 days; P = .6). Conclusion There are specific patterns of volume loss, mediastinal shift, and hemidiaphragm displacement that can be quantified on postlobectomy chest radiographs. Prior sternotomy did not affect postlobectomy radiographic changes or patient outcome. [ABSTRACT FROM AUTHOR]

Purpose. To assess the impact of a pharmacist-managed insulin titration program on achieving clinical goals in an underserved population with diabetes. Methods. The study included 35 subjects followed in a pharmacist-managed insulin titration and 35 matched control subjects. Control subjects were followed under standard procedures within the same clinic and were matched for age, titration time frame, and insulin regimen. The primary outcome was change in A1C between the two groups at 6 months. Secondary outcomes included change in A1C within groups at 3, 6, 9, and 12 months, as well as the proportion of subjects attaining a goal A1C of < 7% and adhering to preventive care recommendations. Results. Between-group comparison demonstrated a significant absolute difference in mean change in A1C at 6 months favoring pharmacist management (0.9%, 95% CI 0.2-1.6, P = 0.009). Within-group comparisons demonstrated significant A1C reduction from baseline at 6 months (-1.1%, 95% CI -1.7 to -0.4, P = 0.002), 9 months (-1.4%, 95% CI -2.0 to -0.7, P < 0.001), and 12 months (-1.3%, 95% CI -2.0 to -0.5, P = 0.001) in the pharmacist- managed group with no significant changes observed in the control group. Conclusion. Pharmacist-managed insulin titration resulted in significant improvement in glycemic control compared to standard care in an indigent population. [ABSTRACT FROM AUTHOR]

Objectives: The rate of recombinant tissue plasminogen activator (rtPA) use for stroke is low among the Chinese-Taiwanese. The study objective was to determine if less restrictive exclusion criteria for rtPA would increase eligibility and the rate of treatment. Methods: This retrospective before-and-after study was conducted from 2006 to 2009. The authors compared stroke patients treated under the old rtPA exclusion criteria (January 2006 to December 2008) with those treated with less restrictive rtPA exclusion criteria (January to December 2009). Rates of eligibility and treatment and reasons for exclusion from rtPA between the two phases were assessed. Results: Of 461 eligible patients during the study period, 333 were evaluated by the old criteria and 128 were evaluated by the less restrictive criteria. Minor or improving stroke was the primary exclusion reason in both groups (194/333, 58% vs. 70/128, 55%). Eligibility for rtPA was increased in the less restrictive criteria (35/127, 27%, 95% confidence interval [CI] = 20% to 36%) compared to the old criteria (40/333, 12%, 95% CI = 8.7% to 16%; p = 0.0001). Fewer patients were excluded due to old age in the less restrictive criteria (0/128, 0%) compared to the old criteria (37/333, 11%; p = 0.0001). The rate of consent refusal increased in the less restrictive criteria (27/128, 21%, 95% CI = 14% to 29%) compared to the old criteria (23/333, 6.9%, 95% CI = 4.4% to 10%; p < 0.0001). Rate of rtPA treatment was unchanged between the less restrictive criteria (8/128, 6.3%, 95% CI = 2.7% to 12%) and the old criteria (17/333, 5.1%, 95% CI = 3% to 8%; p = 0.63). Conclusions: Increasing eligibility for rtPA does not increase the rate of treatment, possibly due to the high symptomatic intracerebral hemorrhage rate among Chinese-Taiwanese, which is a major concern among emergency physicians (EPs), neurologists, and patients. Dealing with perceived safety issues of rtPA is crucial before the rate of treatment can be increased. [ABSTRACT FROM AUTHOR]
