Comparative Study of Serum Lipid Profile in Tobacco Addicts, Tobacco Non-addicts and Head-Neck Malignancy.

The present study was undertaken to evaluate lipid profile in tobacco consumers with and without head and neck malignancy and to see whether tobacco consumption causes same degree of alteration in lipid profile. Prospective study of serum lipid profile in 90 patients was done at Govt. Medical College Hospital. Various details of all participants such as age and sex of patients, detailed history of tobacco consumption were taken. Patients were divided into group I, II and III. Serum lipid profile was studied in 30 patients with tobacco addicts for more than 5 years in the form of tobacco chewing and smoking without head-neck malignancy (Group I), 30 patients with tobacco addicts for more than 5 yrs in the form of tobacco chewing and smoking with head-neck malignancy (Group II) and 30 controls i.e., non-smokers and non-tobacco chewers (Group III). Statistical analysis was done to compare the serum lipid profile (Total Cholesterol, HDL, Ratio, Sr. triglyceride, VLDL, LDL) among the tobacco chewers with head and neck malignancy, non-tobacco consumers and tobacco consumers without malignancy and controls i.e., non-smokers and non-tobacco chewers. There was no significant change in total cholesterol, LDL, VLDL, HDL in patients with tobacco addicts and tobacco non-addicts. Serum triglycerides are significantly decreased in tobacco addicts and in malignancy. Total cholesterol, HDL, and LDL are significantly increased in malignancy as compared to tobacco addicts and tobacco non-addicts. There was no significant change in total cholesterol, LDL, VLDL, HDL in patients with tobacco addicts and tobacco non-addicts. Serum triglycerides are significantly decreased in tobacco addicts and in malignancy.

Mucormycosis in COVID-19 pandemic: study at tertiary hospital in India.

AIM: During the second wave of COVID-19, cases of mucormycosis were increased suddenly over a period of 3 months in Maharashtra, India. An attempt was made to study the clinical profile and risk factors associated with mucormycosis. MATERIALS AND METHODS: A retrospective descriptive study was carried out at a tertiary hospital during May 2021-July 2021. After obtaining informed written consent from the participants, various details of all participants, such as diabetes mellitus, use of steroids in COVID-19 treatment, use of immunosuppressant drugs, oxygen therapy, use of ventilators, complications that occurred during treatment, etc., were noted. All mucormycosis patients were treated with amphotericin B and aggressive surgical treatment. RESULTS: In the present study, 74.7% of mucormycosis patients were male. 77.4% of mucormycosis patients were above 40 years of age. 6.7% of mucormycosis patients were partially vaccinated. Among risk factors, 86.6% had diabetes mellitus, 84% had COVID-19 infection, 44% had received steroids, and 54.7% had received oxygen. 80% of patients were present during and within 1 month of COVID-19 infection. 52% of patients were presented in stage III and 41.3% were presented in stage II. Despite aggressive surgical debridement along with amphotericin B, mortality was 25.33%. 5.3% of patients had brain abscesses, 8% of patients had cavernous sinus thrombosis, 4% of patients had facial nerve palsy and 1.3% of patients had meningitis. CONCLUSION: Mucormycosis was predominantly seen in male above the age of 40 years COVID-19 infection and diabetes mellitus was common risk factor for mucormycosis.

COVID-19 at War: The Joint Forces Operation in Ukraine.

The ongoing pandemic disaster of coronavirus erupted with the first confirmed cases in Wuhan, China, in December 2019, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) novel coronavirus, the disease referred to as coronavirus disease 2019, or COVID-19. The World Health Organization (WHO) confirmed the outbreak and determined it a global pandemic. The current pandemic has infected nearly 300 million people and killed over 3 million. The current COVID-19 pandemic is smashing every public health barrier, guardrail, and safety measure in underdeveloped and the most developed countries alike, with peaks and troughs across time. Greatly impacted are those regions experiencing conflict and war. Morbidity and mortality increase logarithmically for those communities at risk and that lack the ability to promote basic preventative measures. States around the globe struggle to unify responses, make gains on preparedness levels, identify and symptomatically treat positive cases, and labs across the globe frantically rollout various vaccines and effective surveillance and therapeutic mechanisms. The incidence and prevalence of COVID-19 may continue to increase globally as no unified disaster response is manifested and disinformation spreads. During this failure in response, virus variants are erupting at a dizzying pace. Ungoverned spaces where nonstate actors predominate and active war zones may become the next epicenter for COVID-19 fatality rates. As the incidence rates continue to rise, hospitals in North America and Europe exceed surge capacity, and immunity post infection struggles to be adequately described. The global threat in previously high-quality, robust infrastructure health-care systems in the most developed economies are failing the challenge posed by COVID-19; how will less-developed economies and those health-care infrastructures that are destroyed by war and conflict fare until adequate vaccine penetrance in these communities or adequate treatment are established? Ukraine and other states in the Black Sea Region are under threat and are exposed to armed Russian aggression against territorial sovereignty daily. Ukraine, where Russia has been waging war since 2014, faces this specific dual threat: disaster response to violence and a deadly infectious disease. To best serve biosurveillance, aid in pandemic disaster response, and bolster health security in Europe, across the North Atlantic Treaty Alliance (NATO) and Black Sea regions, increased NATO integration, across Ukraine's disaster response structures within the Ministries of Health, Defense, and Interior must be reinforced and expanded to mitigate the COVID-19 disaster.

Composition of Brazil Nut (Bertholletia excels HBK), Its Beverage and By-Products: A Healthy Food and Potential Source of Ingredients.

The consumption of plant-based beverages is a growing trend and, consequently, the search for alternative plant sources, the improvement of beverage quality and the use of their by-products, acquire great interest. Thus, the purpose of this work was to characterize the composition (nutrients, phytochemicals and antioxidant activity) of the Brazil nut (BN), its whole beverage (WBM), water-soluble beverage (BM-S), and its by-products of the beverage production: cake, sediment fraction (BM-D), and fat fraction (BM-F). In this study, advanced methodologies for the analysis of the components were employed to assess HPLC-ESI-QTOF (phenolic compounds), GC (fatty acids), and MALDI-TOF/TOF (proteins and peptides). The production of WBM was based on a hot water extraction process, and the production of BM-S includes an additional centrifugation step. The BN showed an interesting nutritional quality and outstanding content of unsaturated fatty acids. The investigation found the following in the composition of the BN: phenolic compounds (mainly flavan-3-ols as Catechin (and glycosides or derivatives), Epicatechin (and glycosides or derivatives), Quercetin and Myricetin-3-O-rhamnoside, hydroxybenzoic acids as Gallic acid (and derivatives), 4-hydroxybenzoic acid, ellagic acid, Vanillic acid, p-Coumaric acid and Ferulic acid, bioactive minor lipid components (ß-Sitosterol, γ-Tocopherol, α-Tocopherol and squalene), and a high level of selenium. In beverages, WBM had a higher lipid content than BM-S, a factor that influenced the energy characteristics and the content of bioactive minor lipid components. The level of phenolic compounds and selenium were outstanding in both beverages. Hydrothermal processing can promote some lipolysis, with an increase in free fatty acids and monoglycerides content. In by-products, the BM-F stood out due to its bioactive minor lipid components, the BM-D showed a highlight in protein and mineral contents, and the cake retained important nutrients and phytochemicals from the BN. In general, the BN and its beverages are healthy foods, and its by-products could be used to obtain healthy ingredients with appreciable biological activities (such as antioxidant activity).

An Evaluation of the Efficacy of LED Light Curing Units in Primary and Secondary Dental Settings in the United Kingdom.

OBJECTIVE: This study aimed to evaluate the irradiance and the quality of LED light curing units (LCUs) in primary and secondary clinics in the UK and to assess the effect of damage, contamination, use of protective sleeves, and distance of light tips to target on the irradiance and performance of LCUs. METHODS: The irradiance levels (mW/cm2) of 26 LED LCUs from general dental practices and 207 LED LCUs from two dental hospitals were measured using a digital radiometer (Blue Phase II, Ivoclar, Vivadent, Amherst, NY). Ten LED light guide tips (Satelec Mini, Acteon, Merignac, France) were selected to evaluate the effect of chipping, contamination (tip debris), and use of protective sleeves and tips to sensor distance on irradiance (mW/cm2) using a MARC Resin Calibrator (Blue Light Analytics, Halifax, Canada). Homogeneity of the light output was evaluated using a laser beam profiler (SP620; Ophir-Spiricon, North Longan, UT, USA). Statistical analysis was conducted using a one-way analysis of variance (ANOVA) with post hoc Tukey test (α=0.05) and linear regression with stepwise correlation tests. RESULTS: Thirty-three percent of the LCUs delivered irradiance output less than 500 mW/cm2. The condition of the light curing tips was poor, with 16% contaminated with resin debris, 26% damaged, and 10% both contaminated and damaged. The irradiance output was significantly reduced in contaminated (62%) and chipped (50%) light curing tips and when using protective sleeves (24%) (p<0.05). Irradiance was also reduced when increasing the distance with 25% and 34% reduction at 7 mm and 10 mm, respectively (p<0.05). CONCLUSION: There remains a lack of awareness of the need for regular monitoring and maintenance of dental LCUs. Damaged and contaminated light curing tips, use of protective sleeves, and increasing the distance from the restoration significantly reduced the irradiance output and the performance of the LCUs.

A service evaluation of an intervention to increase application of topical fluoride varnish in general dental practice in South Yorkshire.

PURPOSE: Dental caries is still common in children in the UK despite many available preventative interventions. Application of topical fluoride varnish can reduce caries experience. National and international guidance recommends at least twice-yearly application of topical fluoride varnish, however guidance is not always followed. This project aimed to first identify the proportion of patients receiving fluoride varnish by their primary care dental practitioner prior to their referral to a secondary care service and subsequently increase this rate by introducing an intervention. METHODS: The intervention required the referring practitioner to document the date of which topical fluoride was applied prior to referral. Referrals without this information were rejected. Data were collected pre and post this change in policy to ascertain fluoride application rates. Parents and children were questioned about the frequency of application, and referral forms were reviewed for practitioner-reported application. RESULTS: Topical fluoride application rates improved by 19% points for patient-reported application, and 31% points for practitioner-reported application. The biggest increase in application rate was in the cohort of patients receiving 6-monthly fluoride application. CONCLUSION: This study demonstrated that a simple intervention, mandating that primary care dental practitioners record the most recent application of topical fluoride before referring a patient to secondary care, can improve the rates of topical fluoride varnish application in the UK.

Anthropometric variables, propulsive force and biological maturation: A mediation analysis in young swimmers.

Youth swimming performance may be influenced by anthropometric and body composition factors during growth. Propulsive force of the arm (PFA) is highly related to swimming performance as 85-90% of the propulsive power comes from the arms. The current study analyzed the mediating effect of biological maturation on the relationship between anthropometric variables and body composition with PFA in young swimmers. A total of 128 swimmers [boys: n = 53, age = 13.6 (1.8) y; girls: n = 75, age = 12.5 (1.8) y] were evaluated. Propulsive force of the arm was estimated by the tethered swimming test. Anthropometric characteristics (body mass, stature, sitting height, arm span, arm muscle area, %body fat, and fat-free mass) were evaluated. Biological maturation was estimated by the age of peak height velocity. Mediation analyses were performed using the Preacher and Hayes bootstrapping method, adjusted for chronological age and sex. All anthropometric and body composition variables, except %body fat, were positively associated with PFA, being mediated by biological maturation. Indirect effects and 95% confidence intervals were: body mass [.20 (.09-.34)], stature [.22 (.11-.43)], arm span [0.17 (.05-.31)], arm muscle area [.74 (.38-1.19)] and fat free-mass [.17 (.05-.34)]. In conclusion, biological maturation mediated the positive associations between body size and composition and PFA in young swimmers.

Environmental Orientation, Green Supply Chain Management, and Firm Performance: Empirical Evidence from Chinese Small and Medium-Sized Enterprises.

This study investigates the relationship between environmental orientation and firm performance with the mediating role of green supply chain management (GSCM). This study uses a survey questionnaire to collect data from 247 CEOs from Chinese small and medium-sized enterprises (SMEs). Structural equation modeling is used to analyze data and test hypotheses. Empirical results show that internal and external environmental orientations are positively related to the three elements of GSCM, namely, environmental selection, monitoring, and collaboration with suppliers which are also positively related to firm performance. In addition, results show that environmental selection, monitoring, and collaboration with suppliers mediates the relationship between internal and external environmental orientations and firm performance. The findings provide important implications for academic researchers and business managers in planning and implementing environmental strategies. In terms of theoretical implications, this study sheds a new light to current knowledge about the effect of environmental orientation on GSCM and firm performance of SMEs. This study also provides empirical evidence to clarify the mediating mechanism of GSCM in the link between environmental orientation and firm performance of SMEs. In terms of practical implications, this study provides knowledge for managers of SMEs to better understand the important role of environmental orientation and green supply chain management. Findings of this study provide knowledge for managers of SMEs to make their business policies better.

Surgical outcomes after uterine artery occlusion at the time of myomectomy: systematic review and meta-analysis.

OBJECTIVE: To systematically review and meta-analyze evidence on surgical outcomes after uterine artery occlusion (UAO) at myomectomy. DESIGN: Systematic review and meta-analysis. SETTING: Not applicable. PATIENT(S): Twenty-six studies involving 2,871 patients located via database searches of MEDLINE, Embase, Web of Science, PubMed, clinicaltrials.gov, and cited references. INTERVENTION(S): Intervention groups undergoing UAO at laparoscopic or abdominal myomectomy (UAO+M) (1,569 patients), and control groups undergoing myomectomy alone (1,302 patients). MAIN OUTCOME MEASURE(S): Primary outcome of surgical blood loss (estimated blood loss, transfusion rate, and change in hemoglobin values), and secondary outcomes including operative time, length of stay, conversion and complications rates, fibroid recurrence, and changes in fibroid-related symptoms. RESULT(S): The patients undergoing UAO+M had a statistically significant reduction in estimated blood loss (mean difference [MD] -103.7 mL; 95% confidence interval [CI], -126.5 to -80.8), blood transfusion (relative risk [RR] 0.24; 95% CI, 0.15-0.39), and change in hemoglobin values (MD -0.60 g/dL; 95% CI, -0.79 to -0.40) compared with controls. Using UAO+M prolonged operative times (MD 10.9 minutes; 95% CI, 3.5-18.2) but shortened the length of stay (MD -0.37 days; 95% CI, -0.62-0.11). Using UAO+M lowered the complication rates (RR 0.73; 95% CI, 0.52-1.00) to the threshold of statistical significance and reduced the risk of fibroid recurrence (RR 0.36; 95% CI, 0.16-0.83) compared with controls. CONCLUSION(S): Uterine artery occlusion at myomectomy is associated with decreased surgical blood loss and transfusion rate compared with control patients. However, further research is required on reproductive outcomes and the effect on ovarian reserve before routine use can be recommended in women desiring future fertility.

An Exploration of the Relationships Among Facial Dimensions, Age, Sex, Dominance Status, and Personality in Rhesus Macaques (Macaca mulatta).

Aspects of personality in nonhuman primates have been linked to health, social relationships, and life history outcomes. In humans as well as nonhuman primates, facial morphology is associated with assertiveness, aggression, and measures of dominance status. In this study we aimed to examine the relationship among facial morphology, age, sex, dominance status, and ratings on the personality dimensions Confidence, Openness, Assertiveness, Friendliness, Activity, and Anxiety in rhesus macaques (Macaca mulatta). We measured facial width-to-height ratio (fWHR) and lower-height/full-height ratio (fLHFH) using photographs from 109 captive rhesus macaques, which observers also assessed for dominance status and personality, and explored the associations among facial morphology, age, sex, dominance status, and personality. fWHR and fLHFH personality associations depended on age category: Assertiveness was associated with higher fWHR and fLHFH, and Confidence was associated with lower fWHR and fLHFH, but all these associations were consistent only in individuals <8 yr. of age. We found fWHR and fLHFH to not be consistently associated with sex or dominance status; compared to younger individuals, we found few associations with fWHR and fLHFH for individuals older than 8 yr., which may be due to limited sample size. Our results indicate that in macaques <8 yr. old, facial morphology is associated with the Assertiveness and Confidence personality dimensions, which is consistent with results suggesting a relationship between fWHR and trait aggression in humans and assertiveness in brown capuchins, all of which implies that fWHR might be a cue to assertive and aggressive traits.

Obstetrical provider knowledge and attitudes towards cell-free DNA screening: results of a cross-sectional national survey.

BACKGROUND: Cell-free DNA (cfDNA) screening has recently acquired tremendous attention, promising patients and healthcare providers a more accurate prenatal screen for aneuploidy than other current screening modalities. It is unclear how much knowledge regarding cfDNA screening obstetrical providers possess which has important implications for the quality and content of the informed consent patients receive. METHODS: A survey was designed to assess obstetrical provider knowledge and attitudes towards cfDNA screening and distributed online through the Society of Obstetricians & Gynecologists of Canada (SOGC). Chi-squared tests were used to detect differences in knowledge and attitudes between groups. RESULTS: 207 respondents completed the survey, composed of 60.6% Obstetricians/Gynecologists (OB/GYN), 15.4% Maternal Fetal Medicine (MFM) specialists, 16.5% General Practitioners (GP), and 7.5% Midwives (MW). MFM demonstrated a significant trend of being most knowledgeable about cfDNA screening followed by OB/GYN, GP, and lastly MW in almost all aspects of cfDNA screening. All groups demonstrated an overall positive attitude towards cfDNA screening; however, OB/GYN and MFM demonstrated a significantly more positive attitude than GP and MW. Despite not yet being a diagnostic test, 19.4% of GP would offer termination of pregnancy immediately following a positive cfDNA screen result compared to none of the MFM and only few OB/GYN or MW. CONCLUSIONS: We have demonstrated that different types of obstetrical providers possess varying amounts of knowledge regarding cfDNA screening with MFM currently having greater knowledge to all other groups. All obstetrical providers must have adequate prenatal screening understanding so that we can embrace the benefits of this novel and promising technology while protecting the integrity of the informed consent process.

Osteologia do membro torácico de Lycalopex gymnocercus Fischer, 1814 (Carnivora, Mammalia): abordagens comparada, radiográfica e osteométrica / Osteology of the thoracic limb in the Lycalopex gymnocercus Fischer, 1814 (Carnivora, Mammalia): comparative, radiograpahic and osteometric approaches

O membro torácico é a parte do esqueleto pós-craniano que mais informações oferece sobre a locomoção e hábitos de vida de uma espécie. Objetivou-se realizar uma descrição macroscópica, comparativa, radiográfica e osteométrica do esqueleto do membro torácico de Lycalopex gymnocercus. Para tal foram analisados ossos de 24 espécimes adultos coletados mortos em rodovias. Foram realizadas descrições macroscópicas e comparadas com as de outros canídeos, imagens radiográficas para reconhecimento dos padrões de trabeculação e topografia óssea, mensurações lineares e tridimensionais e avaliações histológicas das clavículas. O esqueleto do membro torácico de L. gymnocercus apresentou adaptações morfofuncionais em todos os segmentos para a locomoção cursorial especializada e alguma capacidade de pronação e supinação para captura de presas de porte menor. Houve uma tendência de os ossos serem maiores nos machos, especialmente na região distal do úmero, presumivelmente para a fixação de músculos antebraquiais mais fortes. A clavícula vestigial foi encontrada em todos os espécimes, teve natureza predominantemente cartilagínea e foi significativamente maior nos machos. A conformação básica do esqueleto do membro torácico foi semelhante à dos canídeos domésticos e silvestres descritos na literatura, ainda que particularidades de L. gymnocercus sejam encontradas.(AU)

The forelimb is the part of the post-cranial skeleton that provides more information about locomotion and life habits of a species. The objective of this study was to perform a detailed macroscopic, comparative, radiographic and osteometric investigation of the thoracic limb of Lycalopex gymnocercus. Twenty-four adult specimens collected dead from roadkill were studied. Analysis included macroscopic and comparative descriptions to other canids, radiographic images for recognition of trabeculation patterns and topographical arrangement of bones, linear and three-dimensional measurements, and histological evaluation of the clavicles. The forelimb skeleton of L. gymnocercus presented morphological and functional adaptations in every segment for a specialized cursorial locomotion and some ability to pronation and supination for capture of small vertebrates. There was a tendency for the bones to be longer in males, especially in the distal end of humerus, presumably to fixation of stronger antebrachial muscles. The vestigial clavicle bone was found in all the specimens, had a predominantly cartilaginous nature and was significantly larger in males. The basic conformation of the forelimb skeleton was similar to that of domestic and wild canids described in the literature, although peculiar characteristics of L. gymnocercus have been found.(AU)

Chimpanzee Personality and the Arginine Vasopressin Receptor 1A Genotype.

Polymorphisms of the arginine vasopressin receptor 1a (AVPR1a) gene have been linked to various measures related to human social behavior, including sibling conflict and agreeableness. In chimpanzees, AVPR1a polymorphisms have been associated with traits important for social interactions, including sociability, joint attention, dominance, conscientiousness, and hierarchical personality dimensions named low alpha/stability, disinhibition, and negative emotionality/low dominance. We examined associations between AVPR1a and six personality domains and hierarchical personality dimensions in 129 chimpanzees (Pan troglodytes) living in Japan or in a sanctuary in Guinea. We fit three linear and three animal models. The first model included genotype, the second included sex and genotype, and the third included genotype, sex, and sex × genotype. All personality phenotypes were heritable. Chimpanzees possessing the long form of the allele were higher in conscientiousness, but only in models that did not include the other predictors; however, additional analyses suggested that this may have been a consequence of study design. In animal models that included sex and sex × genotype, chimpanzees homozygous for the short form of the allele were higher in extraversion. Taken with the findings of previous studies of chimpanzees and humans, the findings related to conscientiousness suggest that AVPR1a may be related to lower levels of impulsive aggression. The direction of the association between AVPR1a genotype and extraversion ran counter to what one would expect if AVPR1a was related to social behaviors. These results help us further understand the genetic basis of personality in chimpanzees.

The potential use of shear viscosity to monitor polymer conditioning of sewage sludge digestates.

The work assessed the use of shear viscosity at 0.1 s-1 ( [Formula: see text] ) as a parameter to detect changes in the conditioning and dewatering of digestates. Total and soluble fractions of organic matter of digestate samples before and after storage were also assessed in regards to their conditioning and dewatering performance. Digestate from a conventional mesophilic anaerobic digestion (CMAD) and advanced anaerobic digestion (AAD) plants were used. Linear regression and correlation analysis of 29 different parameters showed that soluble and total fractions of organic matter (Norg, Sc, Sp, Tp, TKN/COD, tCOD and sCOD) during plant operation and storage conditions correlated (r between 0.80 and 0.99) with the variation in polymer dose, floc strength and CST of conditioned digestate samples. The variations occurred within the content of soluble and total fractions of organic matter, and showed to correlate with both conditioning requirements and the variation in [Formula: see text] . The work concluded that [Formula: see text] measurements of unconditioned digestate samples have the potential to be used as a parameter to monitor conditioning requirements during digestate storage or during process changes. It was found important to analyse soluble and total fractions of organic matter in order to understand the changes in [Formula: see text] within specific process conditions.

The association between prior statin use and long-term outcomes after critical care admission.

BACKGROUND: Statins may have immunomodulatory effects that benefit critically ill patients. Therefore, we retrospectively examined the association between survival and the prescription of statins prior to admission to an intensive care unit (ICU), or high dependency unit (HDU), as a result of major elective surgery or as an emergency with a presumed diagnosis of sepsis. METHODS: We retrospectively studied critical care patients (ICU or HDU) from a tertiary referral UK teaching hospital. Nottingham University Hospitals have more than 2200 beds, of which 39 are critical care beds. Over a 5-year period (2000-2005), 414 patients were identified with a presumed diagnosis of sepsis, and 672 patients were identified who had planned ICU/HDU admissions following elective major surgery. Patients prescribed statins prior to hospital admission were compared with those who were not. Demographics, medical history, drug history, and Acute Physiology and Chronic Health Evaluation II scores were examined. Univariate and multivariate analyses were applied using the primary end point of survival at 5 years after admission. RESULTS: Patients prescribed statins prior to critical care admission were, on average, older and had higher initial Acute Physiology and Chronic Health Evaluation II scores and more preexisting comorbidities. Statins were almost invariably stopped following admission to critical care. Statin use was not associated with significantly altered survival during hospital admission, or at 5 years, for either patients with sepsis (9% vs 15%, P=.121; 73% vs 84%, P=.503, respectively) or postoperative patients (55% vs 58%, P=.762; 57% vs 63%, P=.390). CONCLUSIONS: Prior statin use was not associated with improved outcomes in patients admitted to critical care after elective surgical cases or with a presumed diagnosis of sepsis.
