Body fat, cardiovascular risk factors and polymorphism in the FTO gene: randomized clinical trial and different physical exercise for adolescents

Abstract Objective: To investigate the effects of different physical exercise programs and polymorphisms of the FTO (fat mass and obesity-associated gene) on body composition and cardiovascular risk factors in adolescents with overweight and obesity. Methods: A randomized, parallel, double-blind clinical trial consisting of the adolescent overweight from the state public network, in a simple representative random sample, who participated in an aerobic exercise or weight training intervention for 10 weeks. Anthropometry, body composition, biochemical markers, sexual maturation, and rs9939609 polymorphism in the FTO gene were assessed. 347 adolescents had their characterization of nutritional status. 72 individuals with overweight and obesity were invited to participate. 39 remained for the start of the program and were randomly allocated to both types of intervention. In the end, 26 subjects participated in the intervention programs, with 12 and 14 in the aerobic and weight training programs, respectively. Results: Heterozygous and homozygous bearers of risk allele A participating in the aerobic program showed improvements in glycemia (p = 0.002) and total cholesterol (p = 0.023) and a reduction in body fat mass (p = 0.041). The weight training program reduced glycemia in patients with the risk allele A (p = 0.027). Cameron's stage four sexual maturation participants were 2.1 times more likely to improve their body fat (CI = 1.31-3.39). Conclusion: Aerobic exercises produced exclusively a significant decrease in fat mass and total cholesterol in patients with risk allele A. Distinct physical exercise programs may cause diverse changes in risk variables related to the health of adolescents.

The use of emergency contraception among female senior high students in the Ho municipality of the Volta Region, Ghana

Background: Emergency contraception (EC) is one option for preventing unplanned pregnancy when it is available and properly used. Unsafe abortions are responsible for nearly one third of maternal deaths in sub-Saharan Africa and about quarter of unsafe abortions are among teenagers.Methods: A quantitative descriptive cross-sectional study. Data was collected using a pretested questionnaire. 260 senior high students were selected using a systematic sampling method in the Volta Region, Ghana. Data were cleaned and entered into SPSS version 22 and analysed into descriptive statistics.Results: Respondents acquired awareness about EC from friends (36.9%), family members (5.6%) and the mass media (41.6%). The required time for EC to be taken were stated as immediately after sex (57.9%), 24 hours after sex (1.2%) and (30.6%) did not know. 28.4% of participants indicated they would not use EC in the future as their faith was against it, 18.0% believed EC is ineffective and 24.9% consider it dangerous to their health. Reasons for use of EC included condom slipped (35.7%), inability to be on daily pill (33.7%), forced unprotected sex (8.2%) and miscalculation of the safe menstrual period (22.4%). There was a significant relationship between age and history of use of EC (p=0.000, c2=8.128, n=260).Conclusions: Strengthening education in Senior High Schools on sexual and reproductive health, with special emphasis on emergency contraceptives as a pregnancy preventive procedure will remain imperative to reducing the canker of maternal mortality attributed to adolescent abortions while improving understanding of the appropriate use of EC.

Knowledge of pregnant women on the factors that influence anaemia in pregnancy in a rural farming district of the Western Region of Ghana

Background: The presence of anaemia in pregnancy is one of the serious public health concerns across the globe especially in developing countries like Ghana. This study assessed pregnant women's knowledge on factors influencing aneamia in pregnancy in a low-income district of Ghana.Methods: A quantitative descriptive cross-sectional study. Data was collected using a pretested questionnaire. 112 pregnant women seeking antenatal care were recruited using systematic sampling technique in the Wassa East district of Ghana. Data were cleaned and entered into SPSS version 22 and analysed into descriptive statistics.Results: Majority of participants; 72.3% did not know the causes of anaemia in pregnancy. Pregnant women (27.7%) indicated nutritional deficiency as a common cause of anaemia; 18.7% of them could identify appropriately at least one sign of anaemia in pregnancy with 28% asserting that pregnancy-related anaemia can affect labour, despite 72% indicating that anaemia could cause maternal mortality. The reasons for irregular ANC attendance included; perceived non importance of ANC (18.8%), financial difficulties (17.9%), health facility inaccessibility (18.8%) and time constraints (44.5%). There was a strong association between knowledge level on the cause of anaemia in pregnancy and the educational level of pregnant women (p=0.005 chi square = 50.289).Conclusions: Lack of knowledge on the importance of antenatal care and financial constraints were among the reasons leading to a surge in anaemia amongst pregnant women in the district. Health providers should incorporate services which enable pregnant women to access valuable information on anaemia prevention in pregnancy.

Intra-abdominal fat measurement by ultrasonography: association with anthropometry and metabolic syndrome in adolescents / Gordura intra-abdominal medida por ultrassonografia: relação com antropometria e síndrome metabólica em adolescentes

Abstract Objective: To associate intra-abdominal fat thickness measured by ultrasonography to the factors related to metabolic syndrome and to determine cutoff points of intra-abdominal fat measurement associated with a greater chance of metabolic syndrome in adolescents. Methods: This was a cross-sectional study, with 423 adolescents from public schools. Intra-abdominal fat was measured by ultrasonography. Anthropometric data were collected, and biochemical analyses were performed. Results: Intra-abdominal fat was measured by ultrasonography, showing a statistically significant association with the diagnosis of metabolic syndrome (p = 0.037), body mass index (p < 0.001), elevated triglyceride levels (p = 0.012), decreased plasma HDL levels (p = 0.034), and increased systemic blood pressure values (p = 0.023). Cutoff values of intra-abdominal fat thickness measurements were calculated by ultrasound to estimate the individuals most likely to develop metabolic syndrome. In the logistic regression models, the cutoff values that showed the highest association with metabolic syndrome in males were 4.50, 5.35, 5.46, 6.24, and 6.50 cm for the ages of 14, 15, 16, 17, and 18/19 years, respectively. In the female gender, the cutoff values defined for the same age groups were 4.46, 4.55, 4.45, 4.90, and 6.46 cm. In an overall analysis using the ROC curve, without gender and age stratification, the cut-off of 3.67 cm showed good sensitivity, but low specificity. Conclusion: Ultrasonography is a useful method to estimate intra-abdominal adipose tissue in adolescents, which is associated with the main factors related to obesity and metabolic syndrome.

Resumo Objetivo: Relacionar a espessura da gordura intra-abdominal medida pela ultrassonografia aos fatores ligados à síndrome metabólica. Determinar pontos de corte da medida da gordura intra-abdominal associados a uma maior chance de síndrome metabólica em adolescentes. Métodos: Estudo seccional, com 423 adolescentes de escolas públicas. A gordura intra-abdominal foi medida pela ultrassonografia. Foram coletados dados antropométricos e feitas análises bioquímicas. Resultados: As medidas da gordura intra-abdominal por ultrassonografia apresentaram associação estatisticamente significativa com o diagnóstico de síndrome metabólica (p = 0,037), índice de massa corporal (p < 0,001), níveis elevados de triglicerídeos (p = 0,012), redução dos níveis plasmáticos de HDL (p = 0,034) e aumento da pressão arterial sistêmica (p = 0,023). Calcularam-se pontos de corte da medida da espessura da gordura intra-abdominal por ultrassom, para estimar os indivíduos com mais chance para o desenvolvimento de síndrome metabólica. Em modelos de regressão logística, os pontos de corte que apresentaram maior associação com a síndrome metabólica no sexo masculino foram de 4,50, 5,35, 5,46, 6,24 e 6,50 cm para as idades de 14, 15, 16, 17 e 18/19 anos, respectivamente. No sexo feminino, os pontos de corte definidos para as mesmas faixas etárias foram de 4,46, 4,55, 4,45, 4,90 e 6,46 cm. Em análise global por meio da curva ROC, sem estratificações por sexo e idade, o ponto de corte de 3,67 cm teve boa sensibilidade, porém apresentou baixa especificidade. Conclusão: A ultrassonografia é um método útil para a estimativa do tecido adiposo intra-abdominal em adolescentes, está associada com os principais fatores relacionados à obesidade e à síndrome metabólica.

Differences between genders in anaerobic capacity during a supramaximal effort

Aim: The present study aimed to verify if there is a difference between genders in anaerobic capacity estimated by energetic equivalents of glycolytic and phosphagen pathways (AC[La-]+EPOCfast). Methods: In this way, 8 men and 8 women (physical education students) were subjected to the following sequence of tests: session 1) graded exercise test to measure the maximal oxygen consumption (VÖ½ O2max) and intensity associated with VÖ½ O2max (iVÖ½ O2max); sessions 2 to 3) familiarization with supramaximal effort at 115% of iVÖ½ O2max; session 4) supramaximal effort at 115% of iVÖ½ O2max to measure AC[La-]+EPOCfast. Results: The AC[La-]+EPOCfast was lower in women compared to men when expressed in absolute and relative values (-38.11%; p=0.01 and -25.71%; p=0.03, respectively). A non-significant difference was observed in performance in the supramaximal effort (-12.08%; p=0.15), besides which, a likely negative inference was observed when comparing women to men. In addition, energetic equivalents of the glycolytic pathway (e[La- ]) were also lower in women when expressed in relative and absolute values (-47.01%; p=0.001 and -36.71%; p=0.001, respectively), however no statistical difference was found for energetic equivalents of the phosphagen pathway (ePCr) (p>0.05). Conclusion: The AC[La-]+EPOCfast is lower in women compared to men, mainly due to differences in the glycolytic pathway.(AU)

Utilization of the oncoscan microarray assay in cancer diagnostics

Current strategies for cancer patient management include the use of genomic and proteomic test results to help guide therapeutic selection. The need for multi-target variant analysis is highlighted by the growing number of novel therapies to treat tumors with specific profiles and the increasing recognition that cancer is an extremely heterogeneous syndrome. Microarray analysis is a powerful genomic tool that provides genome-wide genetic information that is critical for guiding cancer treatments. Unlike constitutional applications of microarray analysis which are performed on whole blood samples, microarray analysis of solid tumors is challenging because tumor tissues are typically formalin fixed and paraffin embedded (FFPE). Genomic DNA extracted from FFPE tissues can also be fragmented into small pieces and yield much lower concentrations of DNA. We validated and implemented the Affymetrix OncoScan® FFPE assay to enable genome-wide analysis from these types of samples. The Affymetrix OncoScan® assay utilizes molecular inversion probes that generate multiplexed array hybridization targets from as short as 40 base-pairs of sequence and as low as approximately 80 ng of genomic DNA. OncoScan microarray analysis provides genomic information that includes structural variations, copy number variations and SNPs in a timely and a cost-effective manner from FFPE tumor tissues (AU)

Mandibular ameloblastoma with lung metastasis 10 years after resection

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To present a case of mandibular ameloblastoma with pulmonary metastasis after ten years and discuss the possible pathophysiology, diagnostic and therapeutic options.<br /><strong>METHODS:</strong><br /><strong> Design:</strong> Case Report<br /> <strong>Setting:</strong> Tertiary Private Hospital<br /><strong> Patient:</strong> One<br /><strong>RESULTS:</strong> A  27-year-old  woman  diagnosed  with  follicular  variant  ameloblastoma  underwent left  segmental  mandibulectomy  with  iliac  bone reconstruction  in  2004.  The  titanium  plates were  removed  in  2008  because  of  a  recurrent  orocutaneous  fistula.  She  was  apparently  well until 2014, when she complained of intermittent, non-radiating, sharp and piercing, right upper back pains.

Attitudes, practices on allergic rhinitis of three socioeconomic classes of Filipinos in the National Capital Region

BACKGROUND: Healthcare access and usage may vary according to socioeconomic class (SEC). Knowing this variable's effect on patient attitudes, practices, and health seeking behavior allows better understanding of compliance, adherence to treatment, and educational needs on allergic rhinitis (AR). OBJECTIVE: This study seeks to assess the attitudes and practices on AR of Filipinos in the National Capital Region. METHODS: A cross sectional survey of 301 Filipinos, stratified into socioeconomic groups ABC1, C2, and DE, was conducted from December 2014 to February 2015. A previously validated and pilot tested questionnaire on AR was administered via structured face to face interviews. RESULTS: Most respondents attributed their symptoms to "colds" (ABC1 77%, C2 79%, DE 78%); most did not consult a physician for their symptoms. Only 26% of all respondents were aware of AR. Only the ABC1 group had respondents who specifically used the term AR. Most respondents' symptoms fulfilled criteria for moderate to severe disease. Sleep was the activity most affected by AR (62%). For symptom relief, over the counter antihistamine-decongestants were the most preferred drug preparations (ABC1 30%, C2 38%, DE 34%). Groups ABC1 and C2 cited family, television, and Internet as the top primary sources of health information; DE cited family, television, and friends. CONCLUSION: Regardless of SEC, Filipinos are not aware of AR. Lack of awareness and gaps in knowledge can result to an underestimation of the condition, decrease in health seeking behavior, unmet patient needs, and undertreatment of disease.

Pterygopalatine fossa infiltration: A radio-anatomic study among adult patients in a tertiary private hospital

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> As   a   guide   to   the   clinical   practice   of   infiltration   of   local   anesthesia   into   the pterygopalatine fossa via the greater palatine canal, this study sought to determine and record the  mean  CT  scan  measurements  of  the  following:  1)  palatal  mucosal  thickness,  2)  length  and width  of  greater  palatine  canal,  and  3)  length  and  width  of  pterygopalatine  fossa  among  adult patients in a private tertiary hospital in Quezon City.<br /><strong>METHODS:</strong><br /><strong>Design:</strong> Retrospective, Descriptive Study<br /><strong>Setting:</strong> Tertiary Private Hospital<br /><strong>Subjects:</strong> Paranasal Sinus (PNS) CT Scans of 113 adult patients from January 2014 to May 2014 were reviewed and evaluated.

Diagnostic Criteria for Meniere's Disease / 대한평형의학회지

This paper presents diagnostic criteria for Meniere's disease jointly formulated by the Classification Committee of the Barany Society, The Japan Society for Equilibrium Research, the European Academy of Otology and Neurotology, the Equilibrium Committee of the American Academy of Otolaryngology-Head and Neck Surgery, and the Korean Balance Society. The classification includes two categories: definite Meniere's disease and probable Meniere's disease. The diagnosis of definite Meniere's disease is based on clinical criteria and requires the observation of an episodic vertigo syndrome associated with low- to medium- frequency sensorineural hearing loss and fluctuating aural symptoms (hearing, tinnitus and/or fullness) in the affected ear. Duration of vertigo episodes is limited to a period between 20 minutes and 12 hours. Probable Meniere's disease is a broader concept defined by episodic vestibular symptoms (vertigo or dizziness) associated with fluctuating aural symptoms occurring in a period from 20 minutes to 24 hours.

Attitudes, practices on allergic rhinitis of generalists and specialists in Philippine National Capital Region

BACKGROUND: Treatment of allergic rhinitis (AR) consistent with consensus guidelines is reported to result in better patient outcomes. However, physicians may manage patients independently of guidelines. Asian data on physician perspectives regarding AR diagnosis and management is limited. OBJECTIVE: The study objective is to assess attitudes and practices on AR of Filipino specialists and generalists. METHODS: A cross sectional survey of 100 specialists and 100 generalists was conducted from November 2014 to January 2015. A previously validated and pilot tested questionnaire was administered via structured face to face interviews. RESULTS: Specialists reported greater adequate knowledge of AR (specialists, 58%; generalists, 39%) and adherence to guidelines (specialists, 84%; generalists, 54%). Diagnostic tests were not routinely used (specialists, 81%; generalists, 92%). Monotherapy, specifically antihistamines, was preferred for mild AR. For moderate-severe AR, preference for monotherapy versus combination therapy (specialists, 49% vs. 51%; generalists, 44% vs. 56%) was similar. Both groups preferred intranasal corticosteroid spray (INCS) for monotherapy and antileukotrienes, antihistamines, INCS for combination therapy. For adjuvant therapy, specialists (82%) preferred nasal irrigation/douche. Primary consideration for choice of therapy was efficacy. Cost was the perceived reason for patients' noncompliance with treatment. CONCLUSION: Despite differences in awareness of and adherence to guidelines, prescribing patterns on management of mild and moderate-severe AR are similar among Filipino specialists and generalists. This can be attributed to a shared perception of efficacy and cost as drivers for therapeutic choices.

Rosai-Dorfman disease presenting as recurrent nasal polyposis

@#OBJECTIVES: To present a case of Rosai-Dorfman disease in an individual with a 14-year history of recurrent nasal polyposis and discuss its clinical presentation, physical examination, radiologic findings, histopathologic characteristics and available treatment. METHODS: Design: Case Report Setting: Tertiary Government Hospital Patient: One RESULTS: A 26-year-old Filipino diagnosed and repeatedly treated medically and surgically for recurrent nasal polyposis underwent repeat endoscopic sinus surgery. A histopathologic impression of Rosai-Dorfman disease was confirmed by positive S-100 and CD1a negative immunochemistry in conjunction with the morphologic findings. CONCLUSION: Rosai-Dorfman disease is a rare entity which should be considered when dealing with recurrent nasal polyposis that is intractable to initial medical and surgical therapies. Histopathologic findings of emperipolesis and immunohistochemical S-100 stains play a key role in the diagnosis but there is yet no definite treatment for this disease.

Nd:YAG membranotomy for preretinal hemorrhage secondary to valsalva retinopathy

To report four cases of premacular hemorrhage secondary to valsalva retinopathy treated with Nd:YAG membranotomy and discuss techniques as well as the literature. Retrospective case series. A retrospective review was conducted for four patients with vision obstructing hemorrhage secondary to valsalva retinopathy. These patients were all treated with Nd:YAG membranotomy. Four patients with premacular hemorrhage secondary to valsalva retinopathy were treated with Nd:YAG laser creating a membranotomy to drain the hemorrhage. Power settings ranged from 1.7 to 3.8 mJ. Visual acuity at presentation ranged from 20/400 [1 patient] to count fingers [3 patients]. Visual acuity improved in three out of four patients after laser treatment. Final visual acuity ranged from 20/20 to 20/30 in these three patients. One patient was lost to follow up after performing laser membranotomy and therefore visual acuity after treatment was not obtained. No complications were noted. Nd:YAG membranotomy is a non-invasive, office-based treatment option that may be successfully used to treat premacular hemorrhage secondary to valsalva retinopathy

Determinantes sociodemográficos, antropométricos e alimentares de dislipidemia em pré-escolares / Sociodemographic, anthropometric and dietary determinants of dyslipidemia in preschoolers

OBJETIVO: O objetivo deste estudo foi investigar os determinantes de dislipidemia em pré-escolares. MÉTODOS: A partir de um desenho transversal, foi avaliado um total de 227 pré-escolares com 5 anos de idade residentes em uma área urbana da cidade de Diamantina, Minas Gerais, Brasil. Foram avaliados: variáveis bioquímicas, antropométricas, condição socioeconômica e comportamental, a partir de um questinário; e ingestão alimentar, a partir de um questionário de fequência de consumo de alimentos. Os padrões alimentares denominados "dieta mista", "fast food" e "não saudável" foram identificados por meio de análise de componentes principais. Os determinantes de dislipidemia foram examinados através da análise de regressão de Poisson. RESULTADOS: A prevalência de dislipidemia, neste estudo, foi de 65,19%. Os pré-escolares que consumiam com menos frequência alimentos do padrão "dieta mista" tiveram um risco maior de concentrações mais altas de lipoproteína de baixa densidade (PR = 2,30; p = 0,004), em comparação com aqueles com um consumo mais frequente do padrão "dieta mista". Os pré-escolares cujas mães apresentaram uma escolaridade mais baixa tiveram menor risco de concentrações mais altas de lipoproteína de baixa densidade (PR = 0,43; p = 0,003), e os pré-escolares que estavam com sobrepeso/obesos apresentaram maior risco de concentrações mais altas de lipoproteína de baixa densidade (PR = 2,23; p = 0,003). CONCLUSÃO: Os determinantes de dislipidemia identificados neste estudo foram o consumo menos frequente de alimentos do padrão "dieta mista", índice de massa corporal mais alto e um maior nível de escolaridade materna. Este estudo mostra que, apesar da baixa idade do grupo em estudo, já estão apresentando alta prevalência de dislipidemia, que é um fator de risco importante para doença cardiovascular.

OBJECTIVE: To investigate the determinants of dyslipidemia in preschoolers. METHODS: A total of 227 preschoolers residing in an urban area of the city of Diamantina, Minas Gerais, Brazil were evaluated at age 5 years, using a cross-sectional design. Dietary intake from a food frequency questionnaire, anthropometric/biochemical parameters, and socioeconomic/behavioral information from a questionnaire were evaluated. 'Mixed diet', 'snack', and 'unhealthy' dietary patterns were identified using principal component analysis. The determinants of dyslipidemia were examined using Poisson regression analysis. RESULTS: The prevalence of dyslipidemia in this study was 65.19%. Preschoolers who less frequently consumed foods in the 'mixed diet' dietary pattern had a higher risk of high concentrations of low-density lipoprotein cholesterol (PR = 2.30; p = 0.004) when compared with those with more frequent consumption of the 'mixed diet' dietary pattern. Preschoolers whose mothers had lower levels of education presented a lower risk of high concentrations of low-density lipoprotein cholesterol (PR = 0.43; p = 0.003), and preschoolers who were overweight/obese presented with greater risk of high concentrations of low-density lipoprotein cholesterol (PR = 2.23; p = 0.003). CONCLUSION: The determinants of dyslipidemia identified in this study were less frequent consumption of foods in the 'mixed diet' dietary pattern, higher body mass index, and higher level of maternal education. This study shows that despite the young age of the group under study, they already present a high prevalence of dyslipidemia, which is an important risk factor for cardiovascular disease.
