To assess the prevalence of abortion among population groups and changes in rates between 2008 and 2014.We used secondary data from the Abortion Patient Survey, the American Community Survey, and the National Survey of Family Growth to estimate abortion rates. We used information from the Abortion Patient Survey to estimate the lifetime incidence of abortion.Between 2008 and 2014, the abortion rate declined 25%, from 19.4 to 14.6 per 1000 women aged 15 to 44 years. The abortion rate for adolescents aged 15 to 19 years declined 46%, the largest of any group. Abortion rates declined for all racial and ethnic groups but were larger for non-White women than for non-Hispanic White women. Although the abortion rate decreased 26% for women with incomes less than 100% of the federal poverty level, this population had the highest abortion rate of all the groups examined: 36.6. If the 2014 age-specific abortion rates prevail, 24% of women aged 15 to 44 years in that year will have an abortion by age 45 years.The decline in abortion was not uniform across all population groups.

Recent years have seen a paradigm shift in the management of patients with diabetes mellitus. Rather than good glycaemic control being the sole primary aim, the therapeutic focus has broadened to consider potential additional cardiovascular and renal benefits. Sodium-glucose co-transporter 2 inhibitors, such as empagliflozin, canagliflozin and dapagliflozin, have gained increasing prominence, with evidence suggesting significant improvement in outcomes in patients with established cardiovascular and renal disease. Here, we discuss the benefits and relative risks of these novel agents and highlight important clinical issues of relevance to general physicians.

Often, catch and release regulations are meant to maximize a fisheries potential to create trophy fish. I evaluated adult Brown Trout populations at five locations within Rapid Creek within Rapid City, SD over a two-year period. In each year, one of these locations was within a catch and release area, while two were outside. In 2012, density and biomass estimates were higher in a site located outside of the catch and release area. Additionally, size structure within the catch and release area was only significantly larger than one of the two sites outside of the regulation area. Mean relative weight values were inversely related to density estimates, with the lowest density sites having the highest mean relative weights. Similarly, a site outside of the catch and release area had the highest abundance and biomass estimates in 2013. The cumulative length distribution was significantly different between the site within the catch and release area and the two located outside. Relative weight was significantly higher in the catch and release area than the two sites outside. As population characteristics within the catch and release area were not consistently better than outside, it is more likely that factors such as habitat and density dependence are impacting the Brown Trout population more than the regulation itself.

The objective of this study was to evaluate the effect of modified atmosphere packaging (MAP) on fish skin, gills and intestines bacterial microbiome. Whole gilthead seabream was packed aerobically or under modified atmospheres (60% CO2, 30% N2, 10% O2) and stored isothermally at 0 °C. Next Generation Sequencing (NGS) analysis was applied for the characterization of fish microbiome on fish skin, gills, and intestines initially (time of packaging, 1 day after harvesting) and after 10 days of isothermal storage at 0 °C. NGS results indicated statistically significant differences in families’ richness and diversity in the tested fish tissues between aerobic and MAP packaging during storage at 0 °C. The most persistent bacteria were Proteobacteria for both packaging types. For fish skin microbiota, the initially prevailing families were Comamonadaceae, Enterobacteriaceae and Moraxellaceae while in the intestines Comamonadaceae, Anaplasmataceae, Bacillaceae and Enterobacteriaceae were the dominant bacteria. At the end of storage period, the fish microbiota was dominated by psychotropic and psychrophilic families (Pseudoalteromonadaceae, Psychromonadaceae, and Shewanellaceae), while families such as Comamonadaceae were persistent under MAP conditions. By 8 days of fish storage at 0 °C, ΜΑΡ samples exhibited higher sensory scorings than the respective aerobically stored fish, indicating better retention of fish freshness and fish quality attributes under MAP. Based on the results of the study, MAP modified significantly the microbiological status and extended the shelf life of fish. NGS was a powerful tool that provided a more complete assessment compared to a culture-based analysis.

Fresh fish, and especially fatty species, are highly perishable due to oxidative deterioration of fish flesh and the elevated microbial load on fish surface. The implementation of a variety of “mild hurdles” may significantly decrease the rates of fish chemical degradation and microbiological spoilage, by better retaining the initial quality, compared to more intense preservation techniques. The aim of this work is the comparative study of different, single or combined, treatments at 15 °C on the quality and shelf life of chilled eel fillets. Fish fillets were treated using osmotic solutions consisting of glycerol (30%–40%–45%) and 5% NaCl with and without former antioxidant impregnation by using Rosemary Serum. In all cases, water activity decreased to approximately 0.90 after 420 min of osmotic treatment. Untreated and osmotically treated fish fillets were subsequently stored at 4 °C and their stability under chill conditions was assessed based on microbial growth and oxidative deterioration. Microbial growth of treated samples was significantly delayed, especially due to the osmotic step (OS) and the derived water activity decrease. Lipid oxidation, a major cause of rejection for fatty fish such as eel, was greatly inhibited in treated fillets, owing to both ‘hurdles’, aw lowering (OS) and antioxidant impregnation with rosemary serum (RS/OS), showing the synergistic effect of these successive procedures. Shelf life of treated eel fillets exhibited a more than 10-fold increase, as compared to the untreated samples, based on chemical composition and a 2 to 3-fold shelf life improvement, in terms of microbial growth.

The objective of the study was to investigate the efficiency of slurry ice during harvesting and transportation of European sea bass (Dicentrarchus labrax) to retain flesh quality and extend shelf life, compared with conventional flake ice. Fish was slaughtered and transported in different mixtures of slurry ice and conventional flake ice (C: slaughtered and transported in 100% flake ice-Control samples, SC: slaughtered in 100% slurry ice and transported in 100% flake ice, S50: slaughtered and transported in 50% slurry ice-50% flake ice, S100: slaughtered and transported in 100% slurry ice) and subsequently stored under controlled isothermal conditions at 0 °C for shelf life modelling and flesh quality evaluation (proteolytic enzymes). The replacement of conventional flake ice with slurry ice as a slaughtering method led to improved quality stability during subsequent refrigerated storage and shelf life extension, in terms of microbial growth, flesh quality and sensory degradation of fish. Based on microbial growth, the shelf life of C samples was found to be 19 days, whereas the shelf life of S50/S100 and SC was 21 and 25 days, respectively, showing that the replacement of flake ice with slurry ice resulted in 2–6 days shelf life extension of whole sea bass stored at 0 °C. The use of slurry ice at slaughter and flake ice in transportation was accompanied by low activities and late peaks of all four enzymes that is expected to lead to delayed proteolytic degradation and extended freshness.

Occurrence of biogenic amines in fresh fish and fishery products constitute a significant safety concern. Ingestion of histamine is identified as the causative agent of several food poisoning incidences on an annual basis. In addition, cadaverine, putrescine and tyramine have been recognized as potentiators of histamine poisoning. Accumulation of biogenic amines in fresh fish and fishery products has been mainly attributed to growth of bacteria possessing amino acid decarboxylase activity, which is facilitated by lack of hygienic conditions and strict temperature control during their storage. To this end, the effectiveness of traditional and modern approaches to control biogenic amine accumulation has been in the epicenter of intensive study. The aim of the present review article is to update and integrate current knowledge regarding the biogenic amine content of fresh fish and fishery products as well as the capacity of traditional and emerging control strategies.

Mitochondrial turnover in the form of mitophagy is emerging as a central process in maintaining cellular function. The degradation of damaged mitochondria through mitophagy is particularly important in cells/tissues that exhibit high energy demands. Skeletal muscle is one such tissue that requires precise turnover of mitochondria in several conditions in order to optimize energy production and prevent bioenergetic crisis. For instance, the formation of skeletal muscle (i.e., myogenesis) is accompanied by robust turnover of low-functioning mitochondria to eventually allow the formation of high-functioning mitochondria. In mature skeletal muscle, alterations in mitophagy-related signaling occur during exercise, aging, and various disease states. Nonetheless, several questions regarding the direct role of mitophagy in various skeletal muscle conditions remain unknown. Furthermore, given the heterogenous nature of skeletal muscle with respect to various cellular and molecular properties, and the plasticity in these properties in various conditions, the involvement and characterization of mitophagy requires more careful consideration in this tissue. Therefore, this review will highlight the known mechanisms of mitophagy in skeletal muscle, and discuss their involvement during myogenesis and various skeletal muscle conditions. This review also provides important considerations for the accurate measurement of mitophagy and interpretation of data in skeletal muscle.

Background Neutrophilic dermatosis of the dorsal hands is an uncommon localised variant of Sweet syndrome first described in 1995. It is characterised by tender erythematous plaques, pustules and bullae on the dorsa of the hands. Literature Review A total of 123 cases of NDDH are included in this review. The mean patient age was 62.1 years and there was a slight female preponderance. 78.0% of cases had reported bilateral involvement and other sites were affected in almost a third of cases. Underlying disease was found in around 40% of patients, with the most common associations being haematological disorders (gammopathies, myelodysplasias or malignancies), recent infection, solid organ tumours and inflammatory bowel disease. Systemic and/or topical corticosteroids were employed in the treatment of 88.1% of cases while dapsone, colchicine and tetracyclines were the commonest steroid-sparing agents used. Improvement was often rapid and complete resolution the norm. Conclusions Whilst being uncommon, NDDH is frequently misdiagnosed and thus, its exact prevalence is probably underestimated. This may have significant implications including treatment delays or incorrect management. Moreover, recognition of NDDH is important since a correct diagnosis should trigger a search for underlying diseases and proper treatment with corticosteroids and/or steroid-sparing agents which is almost invariably curative.

Background Ibrutinib is an oral inhibitor of Bruton’s tyrosine kinase (BTK) that is FDA-approved for several lymphoproliferative disorders and chronic GVHD. Objective To characterize cutaneous eruptions arising from ibrutinib and highlight overlap with epidermal growth factor receptor inhibitor (EGFRi)-induced dermatologic adverse events (dAEs). Methods Single-center retrospective cohort of patients referred to the Skin Toxicities Program for management of cutaneous eruptions while taking ibrutinib. Results Among 19 patients, cutaneous eruptions manifested as facial-predominant papulopustular eruptions, petechiae or ecchymoses, photosensitivity, panniculitis, xerosis, and clinical staphylococcal overgrowth. The majority of patients were able to continue ibrutinib therapy with focused management of their cutaneous toxicities. Limitations This study represents cases at a single tertiary care center and is limited to patients referred for toxicity. Conclusions With the exception of petechiae, the cutaneous toxicities of ibrutinib overlap with those associated with selective EGFR inhibitors. We observed that these reactions can be successfully managed using approaches for EGFR inhibitor-induced cutaneous adverse events.

Resume Introduction La Therapie Comportementale Dialectique (TCD) vise a diminuer la dysregulation emotionnelle, notamment par l’apprentissage en groupe de competences. En mars 2020, le confinement du a la COVID-19 a interrompu brutalement ces groupes. Nous avons poursuivi cet apprentissage par videos YouTube. Notre objectif est d’evaluer la faisabilite de ce format pendant le confinement. Methode Tous les participants a des groupes d’entrainement aux competences TCD realises a Strasbourg ont ete inclus (n = 37). Les videos psychoeducatives ont ete publiees, de facon bihebdomadaire, durant le confinement sur la chaine YouTube « GREMO HUS ». Les participants ont ete encourages a visionner ces videos par appels/messages. Un mois apres la fin du confinement, un questionnaire en ligne a evalue la satisfaction. Resultats Au total, 92 % des patients ont repondu. Sur les 34 repondeurs, 28 (82 %) avaient regarde au moins une video, et 32 % plus de 6 videos. Une tres large majorite des utilisateurs etaient satisfaits des videos. Au total, 79 % se disaient fortement aides dans la comprehension des competences, et 77 % pensaient avoir utilise plus frequemment les competences TCD. Tous sauf un se sont dit aides par les competences pour mieux surmonter les difficultes en periode de confinement. Discussion Notre etude est la premiere a interroger directement des patients concernant des videos YouTube. Ces videos sont jugees pertinentes par les participants en periode de confinement. Leur utilisation pourrait etre un complement des groupes hors confinement, ainsi que pour la formation des therapeutes.

The last 30 years have seen a revolution in the provision of minimal access surgery for many conditions, and technological advances are increasing exponentially. Many instruments are superseded by improved versions before the NHS and publicly funded health services can offer widespread coverage. Although we tend to think of minimal access surgery as a modern concept, Parts I and II of this series have shown that there is a 5000-year history to this specialty and our predecessors laid down many principles which still apply today. During the 19th and early 20th centuries, minimal access surgery was driven forward by visionary individuals, often in the face of opposition from colleagues and the medical establishment. However, in the last 30 years, innovation has been driven more in partnerships between healthcare, scientific, financial, educational and charitable organisations. There are far too many individuals involved to detail every contribution here, but this third part of the series will concentrate on some of the important themes in the development of minimal access surgery to its current status.

The neuraminidase (NA) of influenza A and B viruses plays a distinct role in viral replication and has a highly conserved catalytic site. Numerous sialic (neuraminic) acid analogs that competitively bind to the NA active site and potently inhibit enzyme activity have been synthesized and tested. Four NA inhibitors are now licensed in various parts of the world (zanamivir, oseltamivir, peramivir, and laninamivir) to treat influenza A and B infections. NA changes, naturally occurring or acquired under selective pressure, have been shown to reduce drug binding, thereby affecting the effectiveness of NA inhibitors. Drug resistance and other drawbacks have prompted the search for the next-generation NA-targeting therapeutics. One of the promising approaches is the identification of monoclonal antibodies (mAbs) targeting the conserved NA epitopes. Anti-NA mAbs demonstrate Fab-based antiviral activity supplemented with Fc-mediated immune effector functions. Antiviral Fc-conjugates offer another cutting-edge strategy that is based on a multimodal mechanism of action. These novel antiviral agents are composed of a small-molecule NA inhibitor and an Fc-region that simultaneously engages the immune system. The significant advancements made in recent years further support the value of NA as an attractive target for the antiviral development.

This review will detail the embryology and morphology of the heart. We will begin with the heart's origin in the lateral plate mesoderm of the early embryo, review its fusion into a linear heart tube, followed by looping and remodeling to create a four-chambered organ with pulmonary and systemic venous inflow and pulmonary and systemic arterial outflow. We will discuss important concepts in heart development at genetic, cellular, and physiologic levels and review some key experimental models and methods important to the study of cardiac development. This review will also serve to introduce some of the congenital heart defects that can result from abnormalities in development and some of the genetic syndromes that are linked to congenital heart defects.

• The presentation of urinary tract infections (UTIs) in neonates differs from that seen in older children. • The type and route of infection also differ in neonates, when compared with older children. • An appropriate urine sample for diagnosis is needed, but treatment should not be delayed. • A neonate in whom a UTI is suspected should be evaluated for sepsis, including invasive cultures. • After a documented neonatal UTI, a radiologic work-up is warranted to detect anatomic anomalies. • Vesicoureteral reflux (VUR) is diagnosed in 30%–50% of neonates with proven UTI. • Voiding cystourethrogram is the gold standard for the diagnosis of VUR and should be performed on high-risk neonates. • Treatment of VUR should be tailored to each patient's individual risk of UTI recurrence, with the goals of preventing future UTIs and renal scar formation.

Auxin signaling regulates growth and developmental processes in plants. The core of nuclear auxin signaling relies on just three components: TIR1/AFBs, Aux/IAAs, and ARFs. Each component is itself made up of several domains, all of which contribute to the regulation of auxin signaling. Studies of the structural aspects of these three core signaling components have deepened our understanding of auxin signaling dynamics and regulation. In addition to the structured domains of these components, intrinsically disordered regions within the proteins also impact auxin signaling outcomes. New research is beginning to uncover the role intrinsic disorder plays in auxin-regulated degradation and subcellular localization. Structured and intrinsically disordered domains affect auxin perception, protein degradation dynamics, and DNA binding. Taken together, subtle differences within the domains and motifs of each class of auxin signaling component affect signaling outcomes and specificity.

Summary This is the second of a three-part series that charts the history of minimal access surgery from antiquity to current times. Although rapid developments in laparoscopic and robotic surgery have transformed surgical care over the last 30 years, our predecessors made significant advances in their time which set the principles for modern practice. Part I of this series described how ancient medical practitioners developed simple instruments, from metal or wood, for viewing body cavities. Improvements in the use of metal, glass and lighting allowed for inspection of deeper parts of the body. This second part of the series will show how advances in electrical technology allowed the development of improved lighting for endoscopy and laparoscopy along with the use of electrocautery for a wide range of therapeutic procedures.

This review identifies the three-dimensional knee loads that have the highest risk of injuring the anterior cruciate ligament (ACL) in the athlete. It is the combination of the muscular resistance to a large knee flexion moment, an external reaction force generating knee compression, an internal tibial torque, and a knee abduction moment during a single-leg athletic manoeuvre such as landing from a jump, abruptly changing direction, or rapidly decelerating that results in the greatest ACL loads. While there is consensus that an anterior tibial shear force is the primary ACL loading mechanism, controversy exists regarding the secondary order of importance of transverse-plane and frontal-plane loading in ACL injury scenarios. Large knee compression forces combined with a posteriorly and inferiorly sloped tibial plateau, especially the lateral plateau-an important ACL injury risk factor-causes anterior tibial translation and internal tibial rotation, which increases ACL loading. Furthermore, while the ACL can fail under a single supramaximal loading cycle, recent evidence shows that it can also fail following repeated submaximal loading cycles due to microdamage accumulating in the ligament with each cycle. This challenges the existing dogma that non-contact ACL injuries are predominantly due to a single manoeuvre that catastrophically overloads the ACL.

Background Thumb carpometacarpal (CMC) joint arthroplasty is a common procedure in the surgical management of symptomatic thumb basal joint arthritis. Following trapeziectomy, a number of suspensionplasty techniques are often used, but limited comparative evidence exists between these techniques. The central aim of this study was to prospectively compare the outcomes of 2 suspensionplasty techniques following trapeziectomy: suture button (TightRope) versus ligament reconstruction and tendon interposition (LRTI). Methods Prospective data were collected on 112 consecutive patients with Eaton stage III-IV thumb CMC arthritis who underwent open trapeziectomy and suspensionplasty. There were 53 LRTI and 59 TightRope suspensionplasty procedures. Outcomes were measured using the Quick Disabilities of the Arm, Shoulder, and Hand ( QuickDASH) questionnaire, Visual Analogue Scale (VAS) for pain, radiographic analysis, and lateral pinch strength. Patient demographic data and complications were also recorded. Results Patients undergoing TightRope suspensionplasty had significantly higher trapeziometacarpal index and thus less subsidence than the LRTI group at 2 weeks (0.22 vs 0.17 [ P < .0001]) and 3 months (0.17 vs 0.15 [ P < .05]) postoperatively. TightRope suspensionplasty also had a significantly lower QuickDASH score at 2 weeks (64.7 vs 74.6 [ P < .05]), 3 months (20.7 vs 32.5 [ P < .05]), and 1 year postoperatively (7.57 vs 21.5 [ P < .05]) compared with the LRTI group. However, there was no difference in VAS pain, lateral pinch strength, reoperation, or complications at any time point between groups. Conclusions Thumb CMC joint arthroplasty performed with a TightRope suspensionplasty versus LRTI yielded short-term improved resistance to subsidence, long-term greater improvement in clinical outcome by QuickDASH, and no difference in pain or complication rates.

• Current American Urological Association guidelines do not recommend ultrasound for the evaluation of undescended testicles. • Children with an undescended testicle should be referred to a pediatric urologist at approximately 6 months of age. • Infants with bilateral nonpalpable testicles should be evaluated for possible congenital adrenal hyperplasia. • Infants with hypospadias and unilateral or bilateral undescended testicles should be evaluated for disorder of sexual development. • Repair of hypospadias is recommended at between 6 months and 1 year of age. • Bladder exstrophy repairs are currently delayed to 3 months of age. • A voiding cystourethrogram should be performed in infants with high-grade hydronephrosis and bilateral hydronephrosis. • Most hydroceles in infants are noncommunicating, and infants should be referred to a urologist if they fluctuate in size suggesting a communicating hydrocele. • Vesicoureteral reflux is more common in male infants and has a high rate of resolution.

A new section on the approach to diagnostic histological interpretation, is the overture to this chapter on inherited and developmental disorders. This initial section is split chronologically into the early neonatal and infantile period and later childhood and adulthood; with the intention of reflecting clinical practice as closely and succinctly as possible. Disorders of the biliary tree, bile formation and secretion, and hepatocyte metabolism are the core of this chapter, a merger of chapters 3 and 4 of the previous edition. Considerations on the pathogenetic and/or clinical overlap between developmental, genetic and metabolic disorders were the rationale behind this change. The complexity of hepatocyte metabolism is reflected into the miriad of related pathological conditions. Recent technological advances, particularly in genomics in the last five years, have resulted in a plethora of new entities and changes in terminology, challenging the authors to balance detail and application to clinical practice. Tables and figures from previous editions have been largely kept due to their quality and contemporary relevance, whilst new ones have been added to accommodate new advances (e.g. classification of mitochondrial disorders), a compromise to bridge between the two editions for the accustomed reader. Liver involvement in immunodeficiency and miscellaneous disorders precede the final section on anatomical anomalies. Vascular anomalies are now included in the chapters on vascular disorders.

In the general population, the construct of race is associated with disparities in cognitive aging. There are notable racial group disparities and inequities among people living with schizophrenia (PLWSz). Despite the salience of the construct of race in schizophrenia, there remains a knowledge gap about racial disparities in cognitive impairment among older adults in this vulnerable population. Our study uses mediation analysis to examine racial disparities in cognitive impairment among older adults with schizophrenia.We assess global cognition in PLWSz over age 55 with the Measurement and Treatment Research to Improve Cognition in Schizophrenia cognitive test battery in our "all-comer" sample (There was a Black/non-Black group racial disparity in global cognitive score (-2.8, 95% CI: -4.4, -1.3) after adjusting for confounding and interaction. This disparity was significantly mediated by years of education.There are notable racial disparities in cognitive impairment among older adults with schizophrenia; however, differences in cognitive scores between racial groups are mediated by level of education.Social determinants of health, particularly educational attainment, are important risk factors for cognitive impairment in PLWSz and should be considered by clinicians. Early screening and assessment of cognitive symptoms is essential to addressing health disparities/inequalities among older adults living with schizophrenia.Controlled Direct EffectsHIV: Human Immunodeficiency VirusMATRICS: Measurement and Treatment Research to Improve Cognition in SchizophreniaMCCB: MATRICS Consensus Cognitive BatteryMTE: Marginal Total EffectsNDE: Natural Direct EffectsPANSS: Positive and Negative Symptom ScalePLWSz: People with schizophrenia.

The lateral step-down test is used to appraise movement quality in patients with patellofemoral pain (PFP), however, it is unclear if reliability of the test is affected by physical therapist experience.Determine if there is a difference in reliability between 'experienced' and 'novice' physical therapists appraising movement quality of patients with PFP during the lateral step-down test.Three 'experienced' and 3 'novice' physical therapists analyzed movement quality of 22 participants [mean age (SD) 28.25 (6.5) years] with PFP. Physical therapists viewed two-dimensional videos of participants performing the lateral step-down test and appraised the quality with a score (0-1 = 'good'; 2-3 = 'fair', and 4-5 = 'poor') at baseline and 1 week. Inter- and intra-rater reliability were calculated with kappa and percent agreement. Differences between the groups were assessed with the chi-square test with an a priori alpha level of0.05.Inter- and intra-rater reliability ranged from fair to moderate (ĸ = 0.40-0.65). There was no difference in reliability between 'experienced' and 'novice' physical therapists at baseline (There was no difference in reliability between 'experienced' and 'novice' physical therapists using categories to appraise movement quality during the lateral step-down test for patients with chronic PFP.

Background: Depression is a concern during pregnancy, but it is especially prevalent for pregnant adolescents. Because prenatal depression is a strong predictor of postpartum depression and other forms of psychopathology in both mothers and children, it is important to understand potential risk and protective factors for prenatal depression.Objectives: The present study examined whether social support buffered the impact of childhood trauma on prenatal depression, and whether social support exerted a stronger buffering effect for adolescents compared to adults.Method: Self-reported levels of childhood trauma, social support, and prenatal depression were collected in a racially and ethnically diverse sample of 682 first-time mothers, 58% were adolescents (n = 396; Mage = 17.38 years) and 42% were adults (n = 286; Mage = 26.29 years).Results: Using multi-group moderation analyses, we found that pregnant adolescents with more social support were buffered from the effects of childhood trauma on prenatal depression symptoms, but pregnant adults with more social support were not.Conclusion: Findings support the stress-buffering model in that those with more stressors may benefit more from social support than those with fewer stressors. These results highlight the importance of social support and inform prenatal depression prevention/intervention strategies particularly with pregnant adolescents.

BACKGROUND: The association between obesity (body mass index (BMI) ≥ 30 kg/m(2)) and pattern of medication use during pregnancy in the United States is not well-studied. Higher prepregnancy BMI may be associated with increases or decreases in medication use across pregnancy as symptoms (e.g. reflux) or comorbidities (e.g. gestational diabetes) requiring treatment that may be associated with higher BMI could also change with advancing gestation. OBJECTIVES: To determine whether prenatal medication use, by the number and types of medications, varies by pre-pregnancy obesity status. METHODS: In a secondary data analysis of a racially/ethnically diverse prospective cohort of pregnant women with low risk for fetal abnormalities enrolled in the first trimester of pregnancy and followed to delivery (singleton, 12 United States clinical sites), free text medication data were obtained at enrollment and up to five follow-up visits and abstracted from medical records at delivery. RESULTS: In 436 women with obesity and 1750 women without obesity (pre-pregnancy BMI, 19–29.9 kg/m(2)), more than 70% of pregnant women (77% of women with and 73% of women without obesity) reported taking at least one medication during pregnancy, respectively (adjusted risk ratio (aRR)=1.10, 95% confidence interval (CI)=1.01, 1.20), with 81% reporting two and 69% reporting three or more. A total of 17 classes of medications were identified. Among medication classes consumed by at least 5% of all women, the only class that differed between women with and without obesity was hormones and synthetic substitutes (including steroids, progesterone, diabetes, and thyroid medications) in which women with obesity took more medications (11 vs. 5%, aRR = 1.9, 95% CI = 1.38, 2.61) compared to women without obesity. Within this class, a higher percentage of women with obesity took diabetes medications (2.3 vs. 0.7%) and progesterone (3.4 vs. 1.3%) than their non-obese counterparts. Similar percentages of women with and without obesity reported consuming medications in the remaining medication classes including central nervous system agents (50 and 46%), gastrointestinal drugs (43 and 40%), anti-infective agents (23 and 21%), antihistamines (20 and 17%), autonomic drugs (10 and 9%), and respiratory tract agents (7 and 6%), respectively (p > 0.05 for all adjusted comparisons). There were no differences in medication use by obesity status across gestation. Since the study exclusion criteria limited the non-obese group to women without thyroid disease, in a sensitivity analysis we excluded all women who reported thyroid medication intake and still a higher proportion of women with obesity took the hormones and synthetic substitutes class compared to women without obesity. CONCLUSION: Our findings suggest that pre-pregnancy obesity in otherwise healthy women is associated with a higher use of only selected medications (such as diabetes medications and progesterone) during pregnancy, while the intake of other more common medication types such as analgesics, antibiotics, and antacids does not vary by pre-pregnancy obesity status. As medication safety information for prenatal consumption is insufficient for many medications, these findings highlight the need for a more in-depth examination of factors associated with prenatal medication use.

Leukemia and lymphoma are cancers affecting children, adolescents, and young adults and may affect reproductive outcomes and maternal metabolism. We evaluated for metabolic changes in newborns of mothers with a history of these cancers.A cross-sectional study was conducted on California births from 2007 to 2011 with linked maternal hospital discharge records, birth certificate, and newborn screening metabolites. History of leukemia or lymphoma was determined using ICD-9-CM codes from hospital discharge data and newborn metabolite data from the newborn screening program.A total of 2,068,038 women without cancer history and 906 with history of leukemia or lymphoma were included. After adjusting for differences in maternal age, infant sex, age at metabolite collection, gestational age, and birthweight, among newborns born to women with history of leukemia/lymphoma, several acylcarnitines were significantly (The varied metabolite levels suggest history of leukemia or lymphoma has metabolic impact on newborn offspring, which may have implications for future metabolic consequences such as necrotizing enterocolitis and urea cycle enzyme disorders in children born to mothers with a history of leukemia or lymphoma.

Summary Surgeons and their patients recognise that one of the major advances in surgical technique over the last 20 years has been the growth of minimal access surgery by means of laparoscopic and robotic approaches. Partnerships with industry have facilitated the development of advanced technical instruments, light sources, recording devices and optics which are almost out of date by the time they are introduced to surgical practice. However, lest we think that technological innovation is entirely a modern concept, we should remember that our predecessors were masters of their craft and able to apply new technologies to surgical practice. The history of minimal access surgery can be traced back to approximately 5000 years ago and this review aims to remind us of the achievements of historical doctors and engineers, as well as bring more modern developments to wider attention. This review will comprise a three-part series: Part I 3000BC to 1850 Early instruments for viewing body cavities Part II 1850 to 1990 Technological developments Part III 1990 to present Organisational issues and the rise of the robots

Background Distal-ulna stump (DUS) instability often occurs when performing a distal radioulnar joint (DRUJ) arthroplasty. Recent studies suggest that the distal interosseous membrane (DIOM) reinforces the triangular fibrocartilage complex, providing additional stability to the DRUJ. The aim of this study was to determine whether the DIOM stabilizes the ulnar stump. Methods Twenty fresh-frozen random forearms were dissected. The presence of a distal oblique bundle (DOB) was recorded and measured. The radius was fixed to a vise and the ulna kept free. The DRUJ was fixed with a lag screw. A bone slice was removed by transverse ulna osteotomies 10 and 15 mm proximal to the DRUJ. A 10-N force was applied to the ulna in dorsal and volar directions. Displacements were measured. The DIOM was then transected, and maneuvers and measurements were repeated and compared. Results A distinct distal membrane was present in 70% and a cord-like DOB in 30%. The mean length was 29 mm. Its origin was proximal to the sigmoid notch; its insertion was on the distal third of the ulna, at its lateral border. This attachment is comprised between 39 and 48 mm proximal to the ulnocarpal joint. Initial displacements averaged 22 mm dorsally and 13 mm volarly. After DIOM transection, ulnar translocation increased to 31 mm dorsally and 19 mm volarly. Conclusion In DRUJ arthroplasties, the DIOM does not appear to be a stabilizer of the DUS beneath a useful threshold. Its retaining effect occurs only after an initial 22-mm dorsal displacement, which we consider not clinically admissible. Therefore, in DRUJ arthroplasties, some augmentation might be advisable.

OBJECTIVE: To evaluate whether pathologic complete response (pCR) exclusively defines major pathologic response to treatment with improved survival. SUMMARY BACKGROUND DATA: pCR following trimodality therapy for esophagogastric adenocarcinoma is infrequent but associated with improved prognosis. Yet most clinical trials and correlative studies designate pCR as the primary endpoint. METHODS: We analyzed our prospectively maintained database for patients who underwent trimodality therapy for locally advanced esophageal adenocarcinoma between 1995 and 2017. Overall survival (OS) was examined by percentage treatment response (TR) in the primary tumor bed and pathologic nodal stage (ypN0) using Kaplan-Meier plots. Optimal thresholds of TR for differentiating patients in terms of OS were investigated with descriptive plots using restricted cubic spline functions; associations were quantified using Cox multivariable analysis. RESULTS: Among 788 patients, median follow-up was 37.5 months (range, 0.4–210.6); median OS was 48.3 months (95% CI, 42.2–58.8). Absence of residual nodal disease was independently associated with improved survival (P

Background: The optimal vasopressor management for septic patients with left ventricular (LV) dysfunction has not been well established, and current evidence is conflicting regarding the optimal vasopressor discontinuation order. Objective: The objective was to evaluate the impact of LV dysfunction on the hemodynamic management of septic shock by assessing the incidence of clinically significant hypotension after vasopressor discontinuation. Methods: In this single-center, retrospective cohort study, adult patients were included if they met the Sepsis-3 definition of septic shock, had LV dysfunction (defined as an ejection fraction ≤40%), and received norepinephrine and vasopressin as the last vasopressors discontinued. The primary outcome was the incidence of clinically significant hypotension following discontinuation of vasopressin or norepinephrine. Clinically significant hypotension was defined as a MAP less than 60 mmHg and the need for either: 1) the reinstitution of the previously discontinued agent at any dosage, 2) the receipt of at least 500 mL of a crystalloid at a rate of at least 500 mL/hour, 3) or the receipt of at least 25 grams of albumin 5% at a rate of at least 25 gram/hour. Secondary outcomes included intensive care unit (ICU) and hospital lengths of stay, and ICU and hospital mortality. Results: A total of 78 patients met inclusion criteria, with 37 patients having vasopressin discontinued first and 41 having norepinephrine discontinued first. Clinically significant hypotension occurred in 28 patients (76%) following the discontinuation of vasopressin, compared to 28 patients (81%) following the discontinuation of norepinephrine (p = 0.61). ICU length of stay was 9 days in the vasopressin discontinued first cohort, compared to 15 days in the norepinephrine discontinued first cohort (p = 0.01). There was no statistically significant difference in mortality observed. Conclusion: The discontinuation order of norepinephrine and vasopressin did not impact the incidence of clinically significant hypotension in patients with septic shock and LV dysfunction, but may influence ICU length of stay, although other factors may have impacted this finding.

Environmental awareness consists in the way human beings understand the environment. We observe that relation between humans and the natural environment is a concern related to the currently environmental and social. Thus, this paper aims to identify what we call as environmental perception in students from a 6th grade elementary state school in Sorriso, Mato Grosso. For this case study, we used a semi structured questionnaire with open and closed questions for a group of 63 students. After the answer’s analysis phase, for some previously selected questions, were created categories and tabulated, for other questions, data’s were analyzed and demonstrated in charts. As results, as quoted by several authors, we observed that the environmental and sight perception of the students are coherent for schoolchildren in this age, however, the authors reinforce that the development of projects concerning environmental education are still needed., A percepção ambiental consiste na forma como o ser humano compreende o meio ambiente. Observando a relação do homem com o ambiente natural é uma preocupação pertinente ao quadro ambiental e social, o presente trabalho tem como objetivo identificar aquilo que chamamos de percepção ambiental de alunos de 6° ano do ensino fundamental de uma escola estadual de Sorriso, Mato Grosso. Para este estudo de caso, foi utilizado um questionário semiestruturado com perguntas fechadas e abertas, para um grupo de 63 estudantes. Após a análise do conteúdo das respostas, para algumas questões previamente selecionadas, foram criadas categorias e tabeladas, para outras, os dados foram analisados e demonstrados em tabelas. Foi possível observar que a percepção ambiental dos alunos e a visão de meio ambiente é coerente com o citado por diversos autores para estudantes dessa idade, no entanto, reforçam que ainda há uma necessidade de desenvolvimento de projetos voltados à educação ambiental.

Introduction GOLD 2017 report proposed that the combined COPD assessment should be done according only to symptom burden and exacerbation history in the previous year. Objective This study aims to investigate the change in the COPD groups after the GOLD 2017 revision and also to discuss the evaluation of group C and D as a single group after the GOLD 2019 report. Method The study was designed as a cross-sectional. 251 stable COPD patients admitted to our out-patient clinic; aged ≥40 years, at least one-year diagnosis of COPD and ≥10 pack-year smoking history were consecutively recruited for the study. Results In GOLD 2017, a significant difference was found between the distribution of all groups compared to GOLD 2011 (P = 0,001). 31 patients included in group C were reclassified into group A and 37 patients in group D were reclassified into group B. The FEV1 values of group A and B patients were significantly low and group C and D patients had had exacerbations in more frequently the previous year in GOLD 2017 compared to GOLD 2011. Conclusion After the GOLD 2017 revision, the rate of group C patients decreased even more compared to GOLD 2011 and the group C and D may be considered as a single group in terms of the treatment recommendations with the GOLD 2019 revision. We think that future prospective studies are needed to support this suggestion.

Resumen Para preservar la salud de los jovenes de entre 5-17 anos, la Organizacion Mundial de la Salud recomienda niveles de actividad fisica de al menos 60 minutos al dia de actividad fisica moderada o sostenida. Por tomar el caso de Francia, los jovenes son el grupo de edad mas activo y, en general, estan sanos, pero su nivel de actividad fisica y/o deportiva es insuficiente y disminuye de generacion en generacion. La educacion fisica y deportiva y las practicas deportivas de ocio no son suficientes para compensar el descenso de la actividad fisica en la vida cotidiana. Los analisis demuestran que la inactividad contribuye en gran medida al sobrepeso y la obesidad, factores nocivos para la salud. Ademas, se reconoce que el nivel de actividad fisica en la infancia/adolescencia condiciona el nivel de actividad en la edad adulta. Las ninas y los ninos tienen las mismas capacidades fisicas antes de la pubertad. Su potencial de resistencia aerobica es muy alto, por lo que no es necesario restringirlos por miedo al cansancio o al agotamiento durante esfuerzos de menos de 10-15 minutos. En cambio, su potencial de fuerza es moderado y su potencial de resistencia es bajo. El nino esta «preparado» para el deporte de competicion cuando busca comparar sus propias habilidades con las de sus companeros. En el caso de los deportes de equipo, el nino tambien debe comprender el proceso competitivo subyacente: la estrategia y la cooperacion dentro del grupo. Esto no suele ocurrir hasta la edad de 10-12 anos. Las lesiones por uso excesivo, el sindrome de sobreentrenamiento e incluso el sindrome de agotamiento son posibles en los atletas jovenes. Como las secuelas de estos trastornos pueden tener un impacto significativo en el crecimiento oseo y en el desarrollo psicologico del joven, es importante estar alerta y reaccionar tan pronto como aparezcan los signos prodromicos.

INTRODUCTION Advances in the treatment of myasthenia gravis (MG) have improved quality of life and prognosis for the majority of patients. However, 10%-20% of patients present refractory MG, with frequent relapses and significant functional limitations. PATIENTS AND METHODS Patients with refractory MG were selected from a cohort of patients diagnosed with MG between January 2008 and June 2019. Refractory MG was defined as lack of response to treatment with prednisone and at least 2 immunosuppressants, inability to withdraw treatment without relapse in the last 12 months, or intolerance to treatment with severe adverse reactions. RESULTS We identified 84 patients with MG, 11 of whom (13%) met criteria for refractory MG. Mean (standard deviation) age was 47 (18) years; 64% of patients with refractory MG had early-onset generalised myasthenia (as compared to 22% in the group of patients with MG; P

We performed a retrospective analysis of the patients assessed at our memory unit for whom Alzheimer disease (AD) cerebrospinal fluid biomarker results were available. We selected patients diagnosed with mild cognitive impairment due to AD (National Institute on Aging-Alzheimer's Association clinical criteria), confirmed neuropsychological deficit, a Global Deterioration Scale score of 3, and an abnormal profile of cerebrospinal fluid biomarkers. Of the 588 cases reviewed, 110 met the inclusion criteria. During follow-up, 50 cases (45.45%) progressed to dementia due to AD. Baseline levels of total and phosphorylated tau were higher in the group of patients that progressed to dementia than in those remaining with mild cognitive impairment. After adjusting for age, sex, history of hypertension, diabetes, and educational level, a 10% increase in total tau protein values was associated with a 7.60% increase in the risk of progression to dementia (hazard ratio: 2.22; 95% confidence interval, 1.28-3.84]; P = .004). Among patients with mild cognitive impairment due to AD and abnormal cerebrospinal fluid biomarker profiles, progressively higher concentrations of total or phosphorylated tau were associated with increased risk of progression to dementia.

Prevelar raising/fronting has been documented as a “defining feature” of Pacific Northwest English, yet its status in nearby California remains unclear. This study investigates prevelar raising/fronting across four Californian field sites. Examining word list data from 276 White speakers and sociolinguistic interview data from 64 White speakers, we complicate assumptions of prevelar conditioning in the West in two ways. First, the authors show that the prevelar pattern is not confined to the Pacific Northwest but is extensive throughout California. Results suggest that, in line with previous work in Washington and Oregon, this prevelar pattern is also on the decline among younger Californians, although the trajectory of change appears to differ from that observed in Washington. As this is yet more evidence that the West is broadly participating in similar vocalic patterns, this article tentatively explores historical migration events as one possible source for the contemporary Western vowel system. Second, the authors also complicate phonetic notions of prevelar “tensing,” showing that F1 and F2 are not always operating in tandem: speakers who raise bag, for example, do not always front bag to the same degree, and vice versa. All of this points to an increasingly complex view of the prevelar pattern and one that warrants continued investigations for theories of sound change.

Resumen En junio de 2019 se organizo en Sevilla el primer curso de resonancia magnetica (RM) fetal, con el aval de las sociedades espanolas de Radiologia Medica (SERAM) y Radiologia Pediatrica (SERPE), y se fundo el grupo espanol de RM fetal. Para establecer este grupo, se diseno un cuestionario para radiologos que se dediquen a la imagen prenatal en Espana que anuncio la Sociedad Espanola de Radiologia a sus socios. Las preguntas estaban relacionadas con el tipo de hospital, con los estudios de RM (campo magnetico, edad gestacional, uso de sedacion, numero de estudios por ano, proporcion de estudios de neuroimagen fetal) y con la docencia e investigacion de la RM fetal. Recogimos 41 respuestas de 25 provincias (88% hospitales publicos). Muy pocos radiologos realizan ecografia (7%) o tomografia computarizada prenatal en Espana. La RM se realiza en el segundo trimestre (34%) o tercer trimestre (44%). En el 95% de los centros predominan los estudios del cerebro fetal. El 41% de los centros tienen la posibilidad de realizar sus estudios en RM 3 Tesla. La sedacion materna se usa en el 17% de los centros. El numero de estudios de RM fetal por ano es muy variable, siendo mucho mayor en Barcelona y Madrid que en el resto de Espana.

Current research aims at improving early detection and treatment of cognitive impairment (CI), particularly in patients at high risk for progression to dementia. It is important to treat signs and symptoms as early as possible to normalize quality of life. In older cognitively impaired patients, dentists and physicians should consider polypharmacy, uncontrolled cardiovascular risk factors, depression, metabolic or endocrine derangements, delirium due to intercurrent illness, and dementia, all of which may increase risk for CI and other negative outcomes. An interdisciplinary team approach is a necessity for a responsible and safe treatment sequence.

In this report, we present a series of two unusual cases of elapid snakebite with acute neuroparalysis, that after initial response to standard anti-snake venom therapy, developed recurrence of disabling quadriparesis with dysautonomia, that on detailed evaluation turned out to be immune-mediated polyradiculoneuropathy (GB syndrome). Both the cases then responded to therapy with intravenous immunoglobulins. These cases bring out the rare immune-mediated late complication of snake venom, which if recognized and treated in time, can significantly reduce the morbidity and mortality.

Background and objectives Contribution margin per hour (CMH) has been proposed in healthcare systems to increase the profitability of operating suites. The aim of our study is to propose a simple and reproducible model to calculate CMH and to increase cost-effectiveness. Methods For the ten most commonly performed surgical procedures at our Institution, we prospectively collected their diagnosis-related group (DRG) reimbursement, variable costs and mean procedural time. We quantified the portion of total staffed operating room time to be reallocated with a minimal risk of overrun. Moreover, we calculated the total CMH with a random reallocation on a first come-first served basis. Finally, prioritizing procedures with higher CMH, we ran a simulation by calculating the total CMH. Results Over a two-months period, we identified 14.5 hours of unutilized operating room to reallocate. In the case of a random “first come–first serve” basis, the total earnings were 87,117 United States dollars (USD). Conversely, with a reallocation which prioritized procedures with a high CMH, it was possible to earn 140,444 USD (p Conclusion Surgical activity may be one of the most profitable activities for hospitals, but a cost-effective management requires a comprehension of its cost profile. Reallocation of unused operating room time according to CMH may represent a simple, reproducible and reliable tool for elective cases on a waiting list. In our experience, it helped improving the operating suite cost-effectiveness.

Background The aim of this study was to review, systematically, evidence concerning the link between the ACTN3 R577X polymorphism and the rates and severity of non-contact injuries and exercise-induced muscle damage in athletes and individuals enrolled in exercise training programs. Methods A computerized literature search was performed in the electronic databases PubMed, Web of Science, and SPORTDiscus, from inception until November 2020. All included studies compared the epidemiological characteristics of non-contact injury between the different genotypes of the ACTN3 R577X polymorphism. Results Our search identified 492 records. After the screening of titles, abstracts, and full texts, 13 studies examining the association between the ACTN3 genotypes and the rate and severity of non-contact injury were included in the analysis. These studies were performed in 6 different countries (Spain, Japan, Brazil, China, Republic of Korea, and Italy) and involved a total participant pool of 1093 participants. Of the studies, 2 studies involved only women, 5 studies involved only men, and 6 studies involved both men and women. All the studies included were classified as high-quality studies (≥6 points in the Physiotherapy Evidence Database (PEDro) scale score). Overall, evidence suggests there is an association between the ACTN3 R577X genotype and non-contact injury in 12 investigations. Six studies observed a significant association between ACTN3 R577X polymorphism and exercise induced muscle damage: two with non-contact ankle injury, three with non-contact muscle injury, and one with overall non-contact injury. Conclusion The present findings support the premise that possessing the ACTN3 XX genotype may predispose athletes to a higher probability of some non-contact injuries, such as muscle injury, ankle sprains, and higher levels of exercise-induced muscle damage.

Background Early specialist evaluation during rapid proliferative growth of complicated infantile hemangiomas (IH) is crucial. Health disparities and barriers of access-to-care for children with IH have not been examined. Objective Investigate whether socioeconomic status (SES) is associated with age at subspecialist presentation for IH evaluation. Method Retrospective cohort study of 804 children presenting to a large academic hospital. Primary outcome was age at initial presentation. Covariates included demographic, socioeconomic, geographic, and clinical characteristics. Medicaid or Children's Health Insurance Program (CHIP) were proxies for lower SES. Analysis of covariance, χ2 tests, and generalized ordered logistic regressions were performed. Results Children with lower SES had higher odds of presenting after 3 months of age (OR 2.11, 95% CI 1.31-3.38). In the subset that qualified for institutional care management program (ICMP), no risk factors were associated with delayed presentation. Limitations Use of insurance and economic distress as proxies for SES; exclusion of uninsured children may underestimate racioethnic effects; single academic center study limiting generalizability. Conclusions Children with IH and lower SES were more likely to present later to specialists, but those enrolled in an ICMP did not, suggesting that integrated ICMPs may mitigate disparities and delayed access-to-care for IH among lower SES populations.

Essential voice tremor (EVT) is a voice disorder resulting from dyscoordination within the laryngeal musculature. A low-frequency fluctuations of fundamental voice frequency or the strength of excitation amplitude is the main consequence of the disorder. The automatic classification of healthy control and EVT is useful tool for the clinicians. A typical automatic EVT classification involves three steps. The first step is to compute the pitch contour from the speech. The second step is to compute the features from the pitch contour, and the final step is to use a classifier to classify the features into healthy or EVT. It is shown that a high-resolution pitch contour estimated from the glottal closure instants (GCIs) is useful for EVT classification. The HPRC estimation can be very poor in the presence of noise. Hence, a probabilistic source filter model based noise robust GCI detection is used for HPRC estimation. The Empirical mode decomposition based feature extraction is used followed by a support vector machine classifier. The EVT classification performance is evaluated using recordings from 45 subjects. The proposed method is found to perform better than the baseline techniques in eight different additive noise conditions with six SNR levels.

Neurofibromatosis (NF) is an inherited neuroectodermal abnormality that primarily affects the growth of neural tissues, and Riccardi classified it into eight types. Segmental neurofibromatosis, which is a rare form of neurofibromatosis, is classified as type 5. We report a case for very unusual presentation of segmental NF with unilateral lisch nodules and uncommon sites involving the scalp. Moreover, we could find only one case report of segmental NF with lisch nodules in the literature and could not find any case report involving the scalp.
