Fasting glucose: a cardiometabolic indicator for subclinical atherosclerosis on excess weight adolescents

Abstract Objective: To build a model based on cardiometabolic indicators that allow the identification of overweight adolescents at higher risk of subclinical atherosclerotic disease (SAD). Methods: Cross-sectional study involving 161 adolescents with a body mass index ≥ + 1 z-Score, aged 10 to 19 years. Carotid intima-media complex thickness (IMT) was evaluated using ultrasound to assess subclinical atherosclerotic disease. Cardiometabolic indicators evaluated included nutritional status, central adiposity, blood pressure, lipidic profile, glycemic profile, as well as age and sex. Data was presented using measures of central tendency and dispersion, as well as absolute and relative frequency. The relationship between IMT measurement (outcome variable) and other variables (independent variables) was assessed using Pearson or Spearman correlation, followed by multiple regression modeling with Gamma distribution to analyze predictors of IMT. Statistical analysis was performed using SPSS and R software, considering a significance level of 5 %. Results: It was observed that 23.7 % had Carotid thickening, and the prevalence of abnormal fasting glucose was the lowest. Age and fasting glucose were identified as predictors of IMT increase, with IMT decreasing with age by approximately 1 % per year and increasing with glucose by around 0.24 % per mg/dL. Conclusion: The adolescent at higher risk is younger with higher fasting glycemia levels.

Stimulation of mouse hematopoietic stem cells by angiogenin and DNA preparations

Immature hematopoietic progenitors are a constant source for renewal of hemocyte populations and the basic component of the tissue and cell repair apparatus. A unique property of these cells of internalizing extracellular double-stranded DNA has been previously shown. The leukostimulatory effect demonstrated in our pioneering studies was considered to be due to the feature of this cell. In the present research, we have analyzed the effects of DNA genome reconstructor preparation (DNAgr), DNAmix, and human recombinant angiogenin on both hematopoietic stem cells and multipotent progenitors. Treatment with bone marrow cells of experimental mice with these preparations stimulates colony formation by hematopoietic stem cells and proliferation of multipotent descendants. The main lineage responsible for this is the granulocyte-macrophage hematopoietic lineage. Using fluorescent microscopy as well as FACS assay, co-localization of primitive c-Kit- and Sca-1-positive progenitors and the TAMRA-labeled double-stranded DNA has been shown. Human recombinant angiogenin was used as a reference agent. Cells with specific markers were quantified in intact bone marrow and colonies grown in the presence of inducers. Quantitative analysis revealed that a total of 14,000 fragment copies of 500 bp, which is 0.2% of the haploid genome, can be delivered into early progenitors. Extracellular double-stranded DNA fragments stimulated the colony formation in early hematopoietic progenitors from the bone marrow, which assumed their effect on cells in G0. The observed number of Sca1+/c-Kit+ cells in colonies testifies to the possibility of both symmetrical and asymmetrical division of the initial hematopoietic stem cell and its progeny.

Clinico-epidemiological and patch test profile of patients with suspected allergic contact dermatitis to cosmetics in a Tertiary Care Hospital in the Southern Philippines: A 3-year retrospective study

Background@#Allergic contact dermatitis (ACD) is a common skin inflammatory reaction occurring at the site of challenge with a contact allergen in sensitized individuals and one of the most common causes for consultation in dermatology clinics. Patch testing is a method for detecting the causative component in suspected cases of ACD. Awareness about the causative allergen aids in reducing morbidity and can significantly minimize the impact of ACD in the affected people. @*Objectives@#The study aimed to measure the number of relevant positive reactions in patch tests being performed in our institution in patients with ACD to cosmetic products.@*Methods@#A total of 60 patients who were diagnosed with ACD to cosmetics and underwent patch testing were reviewed to identify the clinico‑epidemiological and patch test profiles of these patients.@*Results@#The study showed that the mean age of patients was 42 comprising mostly of females. Most of the patients were unemployed, office workers, and medical workers. The most common cosmetic products that caused ACD include soaps, shampoos, lotions, and moisturizers. Nickel is still the most tested positive among these patients, followed by fragrance mixes and 4‑phenylenediamine base. They are widely distributed in cosmetic products, especially in soaps and lotions. The pattern of dermatitis revealed facial dermatitis to be the most common reason for consult of these patients.@*Conclusion@#Patch test is valuable in the setting of establishing the etiology of ACD to cosmetic products.

Acrodermatitis continua of Hallopeau in a 47-year-old female

@#A 45-year-old female came to our clinic due to multiple pustules on her fingers. The lesions first appeared when she was 15 years old, starting as a few erythematous macules on her left thumb that eventually developed into painful pustules. The patient claimed that no relief was provided by analgesics and oral antibiotics. Over the next 11 years, the lesions on her left thumb gradually spread to all her fingers including those on her right hand, accompanied by the development of erosions, fissures, and scales, as well as intermittent joint pains and swelling. These symptoms remained unresponsive to multiple topical products, the names of which the patient could not recall. At 24 years old, the patient experienced onycholysis in the first to third digits of her left hand, which progressed to anonychia and eventually affected all the fingers in her left and right hands. When the patient was 38 years old, similar pustules, erosions, fissures, and scaling appeared on several toes. Due to increasing discomfort from lesions spreading to her toes, making it difficult to put on footwear, the patient sought consultation at our dermatology clinic. No symptoms related to pulmonary, gastrointestinal, and genitourinary systems were reported. The patient denied pain or immobility in other joints of her right hand, hair or scalp changes, and oral mucosal lesions. There was no family history of psoriasis, hypertension, peripheral arterial diseases, or other conditions with similar lesions. The patient denied any history of cigarette smoking, chronic alcohol intake, or illicit drug use. On physical examination, the patient appeared comfortable with no signs of distress. We observed multiple erythematous pustules, some coalescing into pus-filled lakes, and thick white hyperkeratotic plaques with scales located on the distal interphalangeal joints, extending to the tips of all digits on both hands. Similar pustules and plaques with scales were seen on the first metatarsophalangeal joint of the right foot and the first digit of the left foot, sparing only the patient’s palms and soles (Figure 1). Anonychia affected all fingers, and there was shortening of all digits on both hands. No hair changes, oral mucosal lesions, or lymphadenopathies noted. The rest of the physical examination findings were unremarkable. Based on the history and clinical findings, we initially assessed the patient as having a form of acropustulosis. Differential diagnoses included infections (e.g., herpetic whitlow, staphylococcal felon, candidal paronychia), which were ruled out due to finger involvement and lack of systemic symptoms. Malignant conditions (e.g., squamous cell carcinoma, acrometastasis) were excluded from the differential diagnoses due to the absence of other typical indicators like trauma, chronic paronychia, exposure to radiation or arsenic fumes, a history of cigarette smoking, or a primary tumor.1 2 Inflammatory conditions (e.g., dyshidrotic eczema, chronic hand contact dermatitis) were also ruled out due to the lack of prominent pruritus, burning sensation, and exposure to common irritants.3 4 Immune-mediated conditions (e.g., palmoplantar pustulosis, palmoplantar psoriasis) were considered but eventually ruled because the patient's lesions did not involve her palms and soles.4 At the time of our evaluation, the patient had normal results in hematology, lipid panel, and liver and kidney function tests. Radiography of the hands showed shortening of the distal phalanges on the first to third digits on both hands, good alignment of osseous structures, intact outlines and trabecular patterns, and normal joint spaces and soft tissue shadows. These findings are consistent with brachydactyly, frequently observed in cases of psoriasis manifesting with dactylitis. Gram stain of the pustules yielded negative results. Histopathology from a skin punch specimen taken from an erythematous plaque on the third digit of the left hand showed focal parakeratosis overlying a spongiotic epidermis with hypogranulosis and psoriasiform hyperplasia. The dermis showed superficial dermal edema and moderately dense perivascular inflammatory infiltrates composed predominantly of lymphocytes and some neutrophils (Figure 1). The final histopathologic impression was psoriasiform dermatitis, ruling out other possible differential diagnoses, including infectious, malignant, and inflammatory conditions. Given the histopathologic consistency with psoriasis, coupled with the clinical presentation of multiple pustules on the tips of the digits and nail changes, the clinicopathologic final diagnosis was acrodermatitis continua of Hallopeau. We initiated oral methotrexate at 10 mg/week for 3 weeks, followed by an increase to 15 mg/week for 7 weeks, reaching a cumulative dose of 135 mg. The patient also received oral folic acid 5 mg daily on days without methotrexate and topical clobetasol propionate 0.05% ointment applied twice daily with occlusion at night. We provided counseling and education about the chronic nature of her condition, emphasizing the need for follow-up every 3 to 6 months. Most pustules resolved, and no new lesions were observed during the tenth week of treatment. No adverse events were reported, and erythema and scaling were significantly lessened. Acrodermatitis continua of Hallopeau (ACH) is a rare form of localized pustular psoriasis characterized by recurrent chronic eruptions of sterile pustules, especially affecting the distal regions of the fingers and toes, and occasionally the nail beds.4 5 The pathophysiology remains poorly understood, but a few authors attribute it to mutations in the interleukin-36RN gene.6 7 8 Diagnosis of ACH can be established based on clinical features. Histopathologic examination and laboratory tests may be helpful in difficult cases, but they are not necessarily performed in all patients.4 6 9 ACH is associated with a wide range of differential diagnoses including infectious paronychia of viral, bacterial, or fungal etiology, dishydrotic eczema, and infected contact dermatitis.4 10 11 Rarely, osteitis and osteolysis of the phalanges may occur in persistent or severe cases.4 6 12 Due to its chronic and relapsing nature, long-term therapeutic control of ACH is necessary to prevent complications.<13 Cirone et al> ACH is recalcitrant to available therapies, with no clear management guidelines or drugs achieving lasting remission.5 Progression to severe disease with irreversible complications is common, and even with treatment, ACH often recurs, affecting patients' physical and psychological well-being.

Is near-infrared spectroscopy a promising predictor for early intracranial hemorrhage diagnosis in the Emergency Department?

Intracranial hemorrhage (ICH) is a serious medical condition that can lead to significant morbidity and mortality if not diagnosed and treated promptly. Early detection and treatment are essential for improving the outcome in patients with ICH. Near-infrared spectroscopy (NIRS) is a non-invasive imaging technique that has been used to detect changes in brain tissue oxygenation and blood flow in various conditions. The aim of this study was to investigate the predictive potential of NIRS for early diagnosis of ICH in patients presenting to the Emergency Department (ED) triage with headache. A total of 378 patients were included in the study. According to the final diagnosis of the patients, 4 groups were formed: migraine, tension-cluster headache, intracranial hemorrhage and intracranial mass, and control group. Cerebral NIRS values "rSO2" were measured at the first professional medical contact with the patient. The right and left rSO2 (RrSO2, LrSO2) were significantly lower and the rSO2 difference was significantly higher in the intracranial hemorrhage group compared to all other patient groups (P<0.001). The cut-off values determined in the receiver operating characteristics (ROC) analysis were RrSO2 ≤67, LrSO2 ≤67, and ΔrSO2 ≥9. This study found that a difference of more than 9 in cerebral right-left NIRS values can be a non-invasive, easy-to-administer, rapid, and reliable diagnostic test for early detection of intracranial bleeding. NIRS holds promise as an objective method in ED triage for patients with intracranial hemorrhage. However, further research is needed to fully understand the potential benefits and limitations of this method.

Rutin forestalls dysregulated cardiac bioenergetics in bisphenol A and dibutyl phthalate-exposed rats through PPAR? and AMPK modulation

Objectives: Proper cardiac function is greatly dependent on adequate supply and metabolism of energy substrates. Environmental pollutants exposure including plasticizers can trigger adverse cardiac metabolic events. This study was designed to investigate the ameliorative effect of rutin (Rt) on dysregulated cardiac energy metabolism in plasticizer-exposed rats. Materials and Methods: Forty-two rats were randomised into seven groups (n = 6): Control (0.1% dimethyl sulfoxide), bisphenol A (BPA, 25 mg/kg, p.o), dibutyl phthalate (DBP, 25 mg/kg, p.o), BPA + Rt 25 mg/kg, Rt 50 mg/kg, DBP + Rt (25 mg/kg, Rt 50 mg/kg), BPA + DBP and BPA + DBP + Rt, daily for 21 days. Results: BPA and DBP exposure increased plasma glucose, reduced insulin, and increased plasma and cardiac free fatty-acid. Cardiac glucose-6-phosphate level, hexokinase and pyruvate dehydrogenase activities increased in DBP while BPA reduced these variables. Cardiac glucose transporter-4 expression was reduced in BPA group, while cardiac peroxisome proliferator-activated receptor-alpha (PPAR?) and AMP-activated protein kinase (AMPK) expression increased in BPA and DBP-treated rats. However, Rt administration prevents impaired cardiac bioenergetics and glucometabolic regulation. Conclusion: Summarily, Rt improves BPA and DBP-impaired cardiac bioenergetics through PPAR? and AMPK modulation.

Reduction of manually irreducible TMJ dislocation with Forceps Traction: Case report in a 60-year-old woman

Chronic protracted TMJ dislocation refers to a condition in which the joint is displaced from its articulation and fixated in that position (open locked) without reduction. The Hippocratic Manoeuvre is usually unsuccessful with a high failure rate, making treatment of this condition very challenging. This article reports a case of TMJ dislocation not amenable to traditional closed reduction method but which was successfully treated using direct application of reduction forceps on the angle of the mandible. The technical aspects of the procedure and post-operative management were also highlighted.

Enhancing special care dentistry with sensory-adapted dental environment A comparative study

Aim: To compare and evaluate the effect of sensory-adapted dental environment (SADE) and regular dental environment in reducing anxiety levels in children with intellectual disabilities. Materials and Methods: This study was carried out in children with mild intellectual disabilities aged 8–13 years. The developmental screening test was utilized in screening and including these children with IQ scores between 52 and 67, and after random allocation, children were subjected to oral prophylaxis in the SADE and regular dental environment. Anxiety levels were assessed at baseline, 5 min, and at the end of the procedure using Venham's anxiety rating scale, pulse rate, and blood pressure values. Results: The data were coded and analyzed using software SPSS (IBM version 22.0) for statistical analysis. Comparison between the groups was done using independent t-test and repeated measured ANOVA for objective assessment of intergroup and intragroup anxiety levels, respectively, and using Mann–Whitney U-test and Friedman's test for subjective assessment of intergroup and intragroup anxiety levels, respectively. Conclusion: These findings suggest that SADE significantly decreased anxiety levels and cooperative behavior in children with mild intellectual disability and can be used as an alternative behavior management technique in effectively handling children with intellectual disability.

Role of an enriched environment in ameliorating early life stress-induced changes in structure and functions of hippocampus and amygdala in rats

Objectives: This study aimed to understand whether an enriched environment (EE) in adulthood benefits in mitigating the early life stress-induced changes in the structure and functions of the hippocampus and amygdala. Materials and Methods: Male Wistar rats were exposed daily for 6 h to early maternal separation and isolation (MS) stress from postnatal days (PND) 4–14 and later at PND 60–70 days subjected to EE, while, the normal control (NC) rats were not subjected to stress but reared with the mother under standard housing conditions. The effects of MS and EE on adulthood behaviour were not subjected to stress but assessed by measuring the ambulatory, repetitive and anxiety-like behaviour. The study has also done the plasma corticosterone concentrations. The dendritic remodelling in the amygdala and hippocampus was assessed using the Golgi cox staining approach. Finally, the present study compared the reactive oxygen species-induced lipid peroxidation and total antioxidant capacity in MS rats as an indirect measure of oxidative stress to study the impact of MS stress on the limbic circuit and peripheral organs. Results: MS rats showed increased anxiety and lower plasma corticosterone levels. The pyramidal neurons’ dendritic plasticity displayed a different pattern, with shrinkage in the CA1 hippocampal neurons and hypertrophy in the amygdala’s primary neurons. Variations in antioxidant activity and peroxidation observed in NC to MS across tissues indicate the occurrence and management of oxidative stress in MS. The 10 days of EE in young adulthood helped to reduce MS stress-induced structural abnormalities in hippocampal and amygdala pyramidal neurons, as well as anxiety and plasma corticosterone levels. Conclusion: These findings together indicate that exposure to adverse experiences may cause harmful effects on brain plasticity and behaviour in young adulthood. Exposure to EE may be beneficial in reducing the early life stress-induced pathophysiology later in life.

Efficacy and safety of turmeric 1% emollient cream in the control of chronic kidney disease-associated pruritus in Hemodialysis patients: A randomized double-blind clinical trial

Introduction@#Chronic kidney disease-associated pruritus (CKD-aP) remains a frequent and distressing symptom in hemodialysis patients, fur- ther compromising their quality of life. Turmeric, or Curcuma longa, is a naturally-occurring, widely available product that inhibits major inflamma- tory mechanisms associated with CKD-aP.@*Objectives@#This study aimed to determine the efficacy and safety of turmeric 1% emollient cream versus a bland emollient in the reduction of chronic kidney disease-associated pruritus in hemodialysis patients.@*Methods@#This study was a randomized, double-blind, controlled trial of the effect of turmeric 1% cream in the reduction of chronic kidney disease associated pruritus in hemodialysis patients compared to a bland emollient. The main outcome measure was the proportion of subjects who demonstrated response to treatment, as well as the incidence of adverse effects.@*Results@#Intention to treat analysis on 106 patients, 53 assigned to turmeric 1% cream and 53 to bland emollient cream, was done. There was a sig- nificant difference (P=0.03) in the proportion of patients who achieved treatment success between the turmeric group (66%) and bland emollient group (45%). The mean decrease in pruritus score (VAS) of the group treated with turmeric was significantly greater than that of the bland emol- lient group (P=0.018). No adverse effects were noted in both groups.@*Conclusion@#Among hemodialysis patients diagnosed with CKD-aP, topical application of turmeric 1% cream twice daily for four weeks was supe- rior to that of bland emollient cream based on efficacy and safety outcome measures.

Burden of foodborne trematodiases and taeniasis in selected areas in southern Philippines

Background@#There are limited reports on foodborne trematodiases (FBT) and taeniasis prevalence and distribution in the Philippines. @*Objective@#This study aimed to describe their prevalence and distribution and determine the species causing these infections in selected areas in southern Philippines. @*Methodology@#The study was implemented in selected barangays in Caraga and Davao regions in southern Philippines. School-age children and adults with gastrointestinal manifestations within the last two weeks were examined using the modified Kato thick technique, while adults with cough for more than two weeks underwent sputum examination using NaOH concentration technique. The adult helminths from patients positive for FBT and/or taeniasis were processed, mounted, and stained for species identification.@*Results@#Variable FBT and taeniasis prevalence across geographic areas and population groups was seen with a highly focal distribution. Heterophyidiasis was the most common FBT with a 7.5% (168 out of 2,238) prevalence. Species not known to be endemic in the area were identified including Haplorchis taichui, Opisthorchis felineus, and Echinostoma ilocanum. Variable prevalence of soil-transmitted helminthiasis and schistosomiasis was also seen. @*Conclusion@#The study revealed the hidden burden of FBT and taeniasis and identified species not known to be endemic in selected areas in southern Philippines. Addressing this hidden burden will require enhancing service delivery. This may be done by utilizing more accurate diagnosis, updating treatment guidelines, implementing evidence-based control interventions, and improving surveillance. Integrating control programs, for instance, integrating FBT and taeniasis control with STH and schistosomiasis control, and integrating paragonimiasis control with the national TB program, may also help in optimizing resources.

In vitro quorum quenching activity of eleusine indica crude ethanolic extract against pseudomonas aeruginosa and serratia marcescens

@#<p style="text-align: justify;"><strong>Introduction:</strong> Nosocomial contaminants such as Pseudomonas aeruginosa and Serratia marcescens are increasingly developing resistance to many antibiotics. One of the promising alternatives that may complement, if not substitute, the use of antibiotics is quorum quenching, the process of interfering with chemical signals that mediate communication between microorganisms. Eleusine indica, a ubiquitous grass used traditionally to treat infections, has been shown to contain metabolites, such as fatty acid derivatives and p-coumaric acid, capable of quorum quenching. To date, there has been no study on the quorum quenching activity of E. indica.</p><p style="text-align: justify;"><strong>Objectives:</strong> This study aimed to determine the in vitro activity of crude ethanolic extract of E. indica leaves against selected quorum-sensing regulated virulence factors of P. aeruginosa and S. marcescens.</p><p style="text-align: justify;"><strong>Methodology:</strong> E. indica leaves were collected, washed, air-dried, and homogenized. Following ethanolic extraction and rotary evaporation, the extract was screened for antimicrobial activity through disk diffusion test and broth microdilution assay. The quorum quenching activity of the extract against P. aeruginosa was measured through swarming motility assay, while the activity against S. marcescens was measured through swarming motility and pigment inhibition assays. The quorum quenching assays were conducted in triplicates, and analysis of variance (ANOVA) was performed to identify differences among the treatment groups.</p><p style="text-align: justify;"><strong>Results:</strong> Disk diffusion test revealed that no zones of inhibition formed against both P. aeruginosa and S. marcescens for varying concentrations of up to 200 mg/mL of the crude extract. Likewise, the MIC of the extract against both P. aeruginosa and S. marcescens was determined to be >200 mg/mL. However, it was shown that the extract, at 50 mg/mL, has statistically significant activity (p<0.05) against the swarming motility of P. aeruginosa, and it is 71.6% as effective in reducing the swarming area of the bacteria compared to cinnamaldehyde. This was not observed when the extract was tested against the swarming motility of and pigment production by S. marcescens.</p><p style="text-align: justify;"><strong>Conclusion:</strong> In this study, the quorum quenching activity of the crude ethanolic extract of E. indica leaves was found to be effective against P. aeruginosa but not against S. marcescens. The compounds that will be identified by further studies may conceivably be used as an adjunct therapy in P. aeruginosa infections and as coating agents in medical devices.</p>

Memantine for episodic migraine: A systematic review and meta-analysis

@#<p style="text-align: justify;"><strong>Introduction.</strong> Migraine is a common, debilitating primary headache. Memantine is a non-competitive N-methyl D-aspartate (NMDA) antagonist that lowers neuronal excitability that could prevent migraine attacks. This study aimed to determine the efficacy and safety of memantine in patients with episodic migraine attacks using a systematic review and meta-analysis.</p><p style="text-align: justify;"><strong>Methods.</strong> We searched CENTRAL, MEDLINE, Scopus, Cochrane, LILACS, ClinicalTrials.gov, HERDIN and Google Scholar for relevant studies until July 31, 2020. Prespecified screening and eligibility criteria for inclusion were applied. Included studies underwent methodological quality assessment. Study design, patient characteristics, interventions given, and relevant outcomes were extracted and synthesized.</p><p style="text-align: justify;"><strong>Results.</strong> This review included five relevant articles - two randomized controlled trials (RCT) and three non randomized studies (one retrospective records review and survey, two prospective open-label single-arm trials). There were 109 patients included in the RCTs and 197 patients reported in the non-randomized studies. Pooled data from the two RCTs showed that memantine at 10 mg/day significantly decreased the monthly number of migraine days at 12 weeks compared to placebo with a mean difference of -1.58 [95% confidence interval (CI) -1.84, -1.32]. Non-randomized studies also showed a decrease in migraine days per month with memantine (5 to 20 mg/day) after 12 weeks [95% CI]: -9.1 [-11, -7.23], -7.2 [-8.85, -5.55], and -4.9 [-6.29, -3.51]. Adverse drug events (ADE) did not differ significantly between patients treated with memantine compared to placebo.</p><p style="text-align: justify;"><strong>Conclusion.</strong> Memantine may be effective and well-tolerated as prophylaxis for episodic migraine.</p>

Validation of the Portuguese version of the Community Assessment of Psychic Experiences and characterization of psychotic experiences in a Brazilian sample

Objective: We investigated: i) the reliability and validity of a Brazilian version of the Community Assessment of Psychic Experiences (CAPE), developed to detect and characterize psychotic experiences in the general population; and ii) the association between psychotic experiences, childhood adversity, and cannabis use in a population-based sample. Methods: We performed factorial analyses and generalized linear models with CAPE scores as the dependent variable in a sample composed of 217 first-episode psychosis patients, 104 unaffected biological siblings, and 319 non-psychotic population-based participants. Results: After removing seven items from its positive dimension and two items from its negative dimension, a 33-item Brazilian version of the CAPE showed acceptable adjustment indices (confirmatory fit index = 0.895; goodness of fit index = 0.822; parsimony goodness of fit index = 0.761; root mean square error of approximation [RMSEA] = 0.055, p [RMSEA ≤ 0.05] = 0.04) and internal consistency in all its dimensions (> 0.70). Childhood adversity was associated with higher scores in all three dimensions, as well as with total score. Lifetime cannabis use was associated with higher scores only in the positive dimension. Conclusion: The proposed Brazilian version of the CAPE corroborates the tridimensional approach for assessing psychosis-proneness, and the frequency and severity of psychotic manifestations are distributed as a spectrum in the general population.

Endocrine disruption and infertility: Circulatory hormone and bisphenol A concentrations in infertile Saudi women

Aim: Human infertility is a public problem and a cause of social and psychological complications affecting more than 50 million couples globally. Bisphenol A (BPA) is a ubiquitous environmental endocrine disrupting chemical and has been associated with infertility problems in women.The aim of the present study was to analyze concentrations of bisphenol A and circulating hormones in infertile Saudi women for evaluating the association of BPA with infertility.Methodology: The present study was done on 43 infertile women for evaluating possible association of systemic BPA concentrations with infertility in Saudi Arabia. The clinical indications were irregular menses, hyper-androgenism, multiple small ovarian cysts, polycystic ovarian syndrome and unexplained infertility. Blood samples from infertile women and a control group of 18 healthy fertile women were analyzed and compared for concentrations of BPA and circulatory hormones. Results: The results showed that BPA concentrations were not significantly different between infertile women and controls. BPA concentrations were also not correlated with systemic hormone concentrations in infertile women. Interpretation: Serum BPA levels had no association with hormone imbalance in this cohort of infertile Saudi women. However, considering the previous studies that have shown a relationship of BPA with female infertility, an argument can be made that there might be lower exposure of Saudi population to BPA in comparison to BPA analogues such as BPS (according to recent reports). Therefore, it is suggested to conduct more infertility studies that include detection of BPA and its analogues in infertile Saudi women

Eliminación de huevos de los pequeños estróngilos en la materia fecal de los equinos y su importancia práctica en la posibilidad de tratamientos selectivos / Fecal shedding of equine small strongyle eggs and its practical importance for selective treatment

Resumen Los pequeños estróngilos son los parásitos de mayor prevalencia e importancia en los equinos de todo el mundo, y el desarrollo generalizado de la resistencia de estos nematodos a los antihelmínticos está impulsando la aplicación de tratamientos selectivos (TS) para disminuir o demorar el desarrollo de estos fenómenos. Esta estrategia se basa en conteos de huevos de nematodos en la materia fecal de todos los integrantes del grupo animal para tratar solamente aquellos que sobrepasan un determinado umbral o cut off. Este principio de TS se ve favorecido por la consistencia de los conteos de huevos por gramo de heces (hpg) en los equinos y está siendo empleada en algunos países del hemisferio norte, especialmente en los animales adultos. En la Argentina, existe una ausencia de información básica en relación a las condiciones climáticas, de pastoreo y manejo que podrían resultar en cargas parasitarias y transmisión de nematodos diferentes a las observadas en el hemisferio norte. En este contexto, el objetivo de este estudio fue caracterizar la eliminación de huevos de pequeños estróngilos en 436 equinos de diferentes edades pertenecientes a 19 establecimientos del área central de la Argentina. El 90% de los equinos mostró huevos de estróngilos en las heces y los valores de hpg fueron menores a 200 y mayores a 1.000 en el 32% y 22% de los equinos respectivamente. La distribución de los huevos de estróngilos entre individuos de todas las edades fue sobre-dispersa o agregada, con una media aritmética general de 671,59 ± 789,76 y un valor de k o parámetro de agregación inversa de 0,72 (distribución de la binomial negativa). La edad de los animales (potrillos vs adultos) y los biotipos (deportivo vs trabajo) en la categoría adultos influenciaron la magnitud de los valores del hpg (p<0,001). En esta última categoría el 35% de los animales fue responsable de la excreción de aproximadamente el 80% de los huevos eliminados en las pasturas. Si bien existen algunas diferencias con lo observado en países del hemisferio norte con poblaciones parasitarias más agregadas o sobre-dispersas, los TS para el control de los pequeños estróngilos en equinos adultos podrían también ser una estrategia válida bajo nuestras condiciones para disminuir la presión de selección sobre el genoma parasitario y permitir el desarrollo de poblaciones en refugio.

Abstract Small strongyles are the most prevalent and important parasites in grazing horses throughout the world and the widespread development of antihelminthic resistance has prompted in some countries of the northern hemisphere the application of selective treatments (ST) to reduce or delay the development of these phenomena. This strategy is based on determining strongyle fecal egg counts of all herd members and treating only those exceeding a certain threshold or cut off. However, there is an absence of basic information on horses maintained under climatic, grazing or management conditions different from those observed in the northern hemisphere. In this context, the aim of this study was to characterize the elimination of eggs of small strongyles in horses of different ages from 19 farms in the central area of Argentina. Out of a total of 436 horses, 90% showed positive strongyles egg counts and in these animals the count of eggs per gram of feces (epg) was under 200 and over 1,000 in 32% and 22% of the horses respectively. The distribution of strongyle eggs among individuals of all categories was over-dispersed or aggregated with a general epg arithmetic mean of 671.59 ± 789.76 and a value of the inverse aggregation parameter of 0.72 (negative binomial distribution). The age of the animals (foals vs. adults) and the biotypes in the adult category (sports vs. work) influenced the magnitude of the epg values (P <0.001). In the latter category, approximately 35% of the animals were responsible for the excretion of approximately 80% of the eggs in the pastures. Although some differences on magnitude and distribution of strongyle fecal egg counts were observed in countries of the northern hemisphere, ST of small strongyles in adult equines could also be a valid strategy under Argentinian conditions to reduce the selection pressure on the parasitic genome and allow the development of refugia populations.

Meanings of alcohol, other drugs and corporal practices in dependents of psychoactive substances / Significados do álcool e outras drogas e das práticas corporais em dependentes de substâncias psicoativas

ABSTRACT The objective of the study was to analyze the significance of alcohol, illicit drugs and corporal practices for users of psychoactive substances who are in the process of rehabilitation at CAPS ad. 76 users who were in rehabilitation at CAPS ad Recife/PE were interviewed. Multiplicity was found in the meaning of alcohol and drugs, with negative factors predominating, even considering that alcohol is initially recognized as an element of social integration. Corporal practices presented positive meanings related mainly to body movement and mind occupation. Translated with www.DeepL.com/Translator (free version)

Neurologic outcome of Filipino children diagnosed with central nervous system infection

@# Neurologic infections are related to chronic and life-long neurologic impairment. We aim to describe the outcomes of Filipino children with neurologic infections upon, and within one year from discharge. This data will be useful in developing programs for the prevention and improvement of outcomes in children with neurologic infections. Methods: This is a multicenter, cross-sectional, retrospective cohort study at six tertiary hospitals across the Philippines within four years (2007-2010). A standardized report form was used to collect clinical profile and outcome using inpatient and outpatient records. Neurologic outcome was classified and staged at 3-, 6-, 9- and 12-months postdischarge. Results: A total of 480 patients were included in the analysis (mean age 4.7 ± 5.3 y), most were bacterial in etiology (275 cases, or 57.3%). Severity of illness on admission (Stage 3, p <0.001) and etiologic agent (viral, p <0.001) were correlated with poor neurologic outcome on discharge. Of the 154 patients that had follow-up, 91 cases were observed to have neurologic deficits (severe, 50; moderate, 29; and mild 12). Twenty patients had improvement of neurologic impairment on subsequent follow-up. Motor deficits (64 cases), cognitive disorders (26 cases) and seizures (17 cases) are the most common neurologic sequela

Antimicrobial, cytotoxicity, anticancer and antioxidant activities of Jatropha zeyheri Sond. roots (Euphorbiaceae)

Objective: To evaluate the antimicrobial, antioxidant, cytotoxicity and anticancer activity of fractions from Jatropha zeyheri roots and to explore the phytochemical profile of the most biologically active fraction. Methods: Fractions from Jatropha zeyheri ethyl acetate extract were investigated for antimicrobial activity against a plethora of pathogenic microorganisms of different origins. The cytotoxicity studies of fractions were evaluated in vitro using tetrazolium-based calorimetric assay against human dermal fibroblast, colon adenocarcinoma (Caco-2), breast cancer (MCF-7) and lung cancer (A547) cell lines. The anti-oxidant activity of fractions was determined in vitro against 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and chelation of iron (Fe2+). Gas chromatography mass spectrometry analysis was performed to detect phytochemical constituents in fraction with potent biological activity. Results: Fraction 2 of Jatropha zeyheri roots exhibited the lowest minimum inhibitory concentration of 40 μg/mL against Klebsiella pneumoniae and 80 μg/mL against Candida albicans, Staphylococcus aureus and Mycoplasma hominis. The fractions revealed some varying degrees of cytotoxicity against human dermal fibroblasts yielding LC50 values ranging from 28.96 to 166.52 μg/mL. Fraction 3 exhibited the highest selectivity index value of 2.08 against Klebsiella pneumoniae. Moreover, fraction 2 selectively inhibited the growth of Caco-2 with LC50 of 8.83 μg/mL, compared to other cancerous cell lines. Fraction 2 of Jatropha zeyheri further exhibited IC50 of 19.66, 22.63 and 1.82 μg/mL against DPPH, ABTS and Fe2+, respectively. Gas chromatography mass spectrometry analysis revealed the presence of cyclotetracosane (10.08%), 9-hexacosene (9.40%), hexadecanoic acid (3.90%), (Z)-9-octadecenamide (3.63%), octacosane (2.27%), 11-n-decylheneicosane (2.23%), ethyl vallesiachotamate (2.17%), heneicosanoic acid (2.10%), and octadecanoic acid (2.08%) in fraction 2 of Jatropha zeyheri. Conclusions: These identified compounds, particularly cyclotetracosane (hydrocarbon), may well explain the biological activity of fraction 2 of Jatropha zeyheri, which possesses higher biological activity than other fractions. These compounds can be further investigated for use in treating various bacterial and fungal opportunistic infections associated with HIV-AIDS and related cancers.

Extract from byproduct Psidium guajava standardized in ellagic acid: additivation of the in vitro photoprotective efficacy of a cosmetic formulation

ABSTRACT The fruits of guava, Psidium guajava L., Myrtaceae, are cultivated as food and used in agroindustries, generating byproducts or waste that represent environmental problems and require adequate destination. However, these byproducts present high levels of secondary metabolites and have been awakened interest regarding to its reusing. The extract was standardized in ellagic acid concentration by high performance liquid chromatography. The additivation capacity in the in vitro photoprotective efficacy of guava byproduct extract standardized in ellagic acid was verified as a result of its incorporation in cosmetic formulations, comparing it with a standard product. The extract presented synergy with the chemical UV filter (ethylhexyl methoxycinnamate), enhancing the solar protection factor of the phytocosmetic in 17.99%. Besides that, it was possible to show its antioxidant activity and the presence of secondary metabolites such as phenols and flavonoids. According to the results, it is possible to claim that the extract from the guava's agroindustrial byproducts present potential to be studied and reused, applying on the development of innovative products intended to the photoprotection care.
