Performance of Holstein-Friesian calves drinking desalinated water in the preweaning period

Background: High salinity of drinking water can adversely affect health and productive performance of calves during artificial rearing. Objective: To evaluate the effect of drinking water total dissolved salts (TDS) content on productive performance of Holstein-Friesian calves during artificial rearing. Methods: Twenty-nine newborn Holstein-Friesian calves weighing 39±0.94 kg at birth were randomly assigned to two treatment groups for 56 d. Treatment 1 (n=14) consisted of drinking water with 1,469±75 mg L-1 TDS, while treatment 2 (n=15) used drinking water from the same source but filtered by reverse osmosis to contain 107±31 mg L-1 TDS. Results: Water intake was numerically affected by TDS concentration, increasing 13% (p>0.08) when drinking low-TDS water (3,554 versus 3,088 ml d-1). Feed intake (dry basis) decreased 26% (500 versus 676 g d-1; p0.05) by TDS content in the drinking water. Conclusion: Desalinated water improves productive performance of Holstein-Friesian calves during artificial rearing.

Resultados: O consumo de água de bezerros durante os 56 dias de lactação artificial foi ligeiramente afetado pela concentração de TDS na água potável (p>0,08) e aumentou em 13% quando os bezerros beberam água com baixo teor de sal (3.554 vs 3.088 ml d-1); o consumo de alimento sólido (base seca) diminuiu em 26% (500 vs 676 g d-1; p0,05) pelo conteúdo de TSD na água de beber. Conclusão: A dessalinização da água de beber melhora o comportamento produtivo de terneiros Holstein durante o período de lactação artificial..

Are Saunas Beneficial or Harmful for Autosomal Dominant Polycystic Kidney Disease? Examination with Model Mouse / 日本温泉気候物理医学会雑誌

  Background: Heat shock proteins (Hsps), expression of which are induced by thermal treatment, function in the protection of kidneys by suppressing apoptosis and maintaining renal tubular viability. Moreover, recently, it has been indicated that the expression of Hsps can be a therapeutic target for autosomal dominant polycystic kidney disease (ADPKD). We investigated the effect of dry sauna therapy on ADPKD model mice.  Methods and Results: The mice (male DBA/2FG-pcy mice) were categorized into three groups: controls, TS: pcy mice subjected to prolonged sauna with administered water containing 4% sucrose, SW: pcy mice administered water containing 4% sucrose. The TS group was subjected to sauna sessions twice a week for four weeks. The TS group attained and were maintained at rectal temperatures of approximately 39.0°C, until they were carefully removed from the far infrared-ray device. After 4 weeks of sauna treatment, creatinine and blood-urea-nitrogen (BUN) levels determined by an enzymatic method. The heat shock protein (HSP) or cell growth and size related proteins were analyzed by western blotting. The TS group exhibited marginally higher creatinine and BUN levels than did the control and SW groups, however, the differences were not significant. However, cyst enlargement in the TS group reduced significantly compared to that of the control group. HSP90 expression was slightly decreased in the TS and SW groups relative to the control group (p < 0.01 or p < 0.001, vs. control), as was Erk expression, which is linked to cyst development and proliferation (p < 0.05, TS vs. control). Hsp27 expression and phosphorylation level in the SW group were comparable with that of the control group. However, the TS group had increased levels of Hsp27 and phosphorylation (NS). The expression of pro-caspase-3 in the TS group was marginally lower than that in the control group. However, the activity of caspase-3 in all groups showed no differences.  Conclusion: The findings of this study indicated that 4 weeks of sauna treatment could cause transient dehydration and related renal dysfunction and led to the risk of stimulating cyst growth by increased Hsp27 expression. Moreover, we concluded that prevention of dehydration and cyst growth could be suppressed by taking an appropriate amount of water directly after sauna treatment.

Benefits of water intake on kidney function in older adults: protocol for a randomized controlled trial / Benefícios da ingestão de água na função renal de idosos: protocolo para um estudo clínico randomizado controlado

Objective: The goal of this study is to evaluate the benefits of an increase in water intake guided by a mathematical formula (per kg of body weight) on kidney function in older adults. Methods: Older adults (≥ 65 years old) cared for at the Internal Medicine Unit of a tertiary hospital will be randomized to receive or not guidance on water intake (30 mL/kg per day) after initial assessment of kidney function. After 14 days, participants will be reevaluated through clinical and laboratory examinations. Patients with uncompensated disease will be excluded. The main outcomes will be glomerular filtration rate and laboratory measures such as serum and urinary osmolality, sodium, urea, 24-h urine volume and serum creatinine, uric acid, and copeptin. The Mini Nutritional Assessment (MNA) questionnaire will be applied to participants at each visit. Categorical variables will be described as numbers of cases (%) and compared using the χ2 test whereas continuous variables will be analyzed with Student's t-test in relation to baseline measures. The Generalized Estimating Equations (GEE) method will be performed to assess differences over time and between groups. This study was approved by the Institution's Research Ethics Committee (grant number 16-0153) and is in accordance with the Declaration of Helsinki. Expected Results:By increasing water intake (ml/Kg) we expect to provide an improvement in kidney function in older population assessed by serum creatinine and cystatin-c applied to eGFR formulas. Relevance:Many conditions, both organic and behavioral, can contribute to chronic dehydration states in older adults. To mention, decreased ability to concentrate urine, reduced kidney mass, blood flow, and glomerular filtration rate (GFR) along with changes in sensitivity to hormones such as renin, vasopressin and natriuretic peptide can generate water imbalance, leading to dehydration. For being simple and inexpensive, this strategy may be broadly used and bring several health benefits to older adults.

Objetivo: O objetivo deste estudo é avaliar os benefícios de um aumento da ingestão de água guiado por uma fórmula matemática (por kg de massa corporal) na função renal de idosos. Metodologia:Idosos (≥ 65 anos) atendidos pelo Serviço de Clínica Médica de um hospital terciário foram randomizados para receber ou não orientação sobre o consumo de água (30 mL/kg por dia) após uma avaliação inicial da função renal. Após 14 dias, os participantes serão reavaliados através de exames clínicos e laboratoriais. Pacientes com doença descompensada serão excluídos. Os desfechos principais são a taxa de filtração glomerular e medidas laboratoriais como osmolaridade, sódio e ureia séricos e urinários, volume de urina de 24 horas e creatinina, ácido úrico e copeptina séricos. A Mini Avaliação Nutricional (MNA) será aplicada aos participantes a cada consulta. Variáveis categóricas serão descritas como números de casos (%) e comparadas usando o teste χ2 , enquanto variáveis contínuas serão analisadas com o teste t de Student em relação às medidas iniciais. O método de Equações de Estimativas Generalizadas (GEE) será usado para avaliar diferenças ao longo do tempo e entre grupos. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa da nossa Instituição (processo número 16-0153) e está de acordo com a Declaração de Helsinki. Resultados esperados:Ao aumentar a ingestão de água (ml/Kg) esperamos proporcionar uma melhora na função renal na população idosa avaliada pela creatinina sérica e cistatina-c aplicada às fórmulas de eGFR. Relevância:Muitas condições, tanto orgânicas quanto comportamentais, podem contribuir para estados de desidratação crônica em idosos. Vale mencionar que a diminuição da capacidade de concentração da urina, redução da massa renal, fluxo sanguíneo e taxa de filtração glomerular (TFG) juntamente com alterações na sensibilidade a hormônios como renina, vasopressina e peptídeo natriurético podem gerar desequilíbrio hídrico, levando à desidratação. Por ser simples e de baixo custo, essa estratégia pode ser amplamente utilizada e trazer diversos benefícios à saúde dos idosos.

Occurrence of common diseases due to habitual food habit or other habit among the students from different regions of Chattogram, Bangladesh

Background:There are some common diseases found among the students of different areas in Bangladesh which are either communicable or non-communicable. Different infectious diseases occur due to lack of hygiene practice and non-infectious diseases are developed because of many irregular daily habits all over the world. Our aim was to evaluate the habit of practicing hygiene and other daily activities to observe their impacts on the health status among the students from different regions of Chattogram in Bangladesh.Methods:With ethical approval, questionnaire forms of daily habits/activities were filled up by 750 students of different educational institutions. The data were analysed afterwards. Results:Among the population of the study 89% (n=667) students werefound to take regular bath; hand washing was regular among 32% (n=240) students, 54% (n=405) students were irregular in hand washing and the rests wash their hands rarely; on the other hand 41% (n=308) students consume street foods regularly; 38% (n=285) students wear eyeglasses due to weak sight; 23% (n=173) suffer from different skin diseases and 63% (n=473) students usually suffer from different gastro intestinal diseases.Conclusions:Our results are not so frustrating, but also not so much good as majority of the students are fond of unhealthy street foods, don’t wash hands regularly and more than half of the students suffer from GI tract diseases with other health problems. It could be recommended that some daily habits including avoiding street foods, intake of sufficient drinking water and hygiene practices should be improved more.

Exposição a fluoreto por crianças na faixa etária crítica para fluorose dentária, residentes no semiárido brasileiro / Exposure to fluoride of children during the critical age for dental fluorosis, in the semiarid region of Brazil

Resumo Há uma preocupação com o aumento da prevalência de fluorose dentária, que depende da dose de fluoreto (F) a que as crianças são submetidas durante a formação dos dentes. A temperatura ambiental afeta a ingestão de água e, portanto, seria importante avaliar se as crianças que vivem em uma região de clima semiárido estão expostas a uma dose excessiva de F. Assim, o objetivo do presente estudo foi determinar a dose total de F a que as crianças são expostas durante a idade crítica para a fluorose dentária, tendo dieta (água e alimentos) e dentifrício como fontes de F, em uma região de clima semiárido no Brasil. Metodologia: foram selecionadas 26 crianças com idade de 25,2 ± 9,1 meses, residentes em Feira de Santana-BA. Foram coletadas amostras de dieta-duplicada, água, produtos de escovação e dentifrícios. A concentração de F foi determinada após o devido preparo das amostras, utilizando um eletrodo específico. Resultados: a média e o desvio padrão de dose (mg F / kg / dia) em função da dieta, dentifrício e total foram, respectivamente: 0,016 ± 0,010; 0,030 ± 0,039 e 0,047 ± 0,043. Conclusões: as crianças avaliadas, residentes em uma região de clima semiárido, não estão expostas a uma dose de risco de fluorose dentária.

Abstract There is a concern about the increasing prevalence of dental fluorosis, which depends on the dose of fluoride (F) to which children are subjected during tooth formation. Environmental temperature affects water intake and therefore it would be important to assess whether children living in the semiarid region are exposed to an excessive dose of F. Therefore, the objective of this study was to determine the total dose of F to which children are exposed during the critical age for dental fluorosis, with diet (water and food) and toothpaste as F sources, in the semiarid region of Brazil. Methodology: 26 children aged 25.2 ± 9.1 months, residents in Feira de Santana, State of Bahia (with F in the public water supply) were selected. Duplicate-diet, water, products from toothbrushing and toothpaste samples were collected. F concentration was determined using an ion-specific electrode, after proper sample preparation. Results: the mean and standard deviation of dose (mg F/kg/day) from diet, toothpaste and total were respectively: 0.016 ± 0.010; 0.030 ± 0.039 and 0.047 ± 0.043. Conclusions: the children evaluated living in the semiarid region are not exposed to a risk dose for dental fluorosis.

Exploratory Study of the Prevalence of Major Chronic Disease According to Daily Water Intake and Physiological Parameters related to Dehydration in Korean Elderly: Based on the Sixth Korea National Health and Nutrition Examination Survey (2015)

PURPOSE: The aim of this study was to explore the prevalence of major chronic diseases related to daily oral water intake and to identify the physiological parameters related to dehydration in Korean elderly. METHODS: The data were collected from the sixth Korea Health and Nutrition Examination Survey (KHANES), which was a nationwide and cross-sectional survey in 2015. We analyzed 1,392 participants using t-test and logistic regression. All participants were divided into the adequate water intake (AWI) group and the non-adequate water intake (NAWI) group based on the dietary reference intakes for Koreans. RESULTS: There was a significant difference in the water intake between the AWI (6.8 cups in a day) and NAWI (2.8 cups) groups (p < .001). There was no statistically significant association between the level of water intake and any of the major chronic diseases. Blood urea nitrogen (BUN) and BUN/Creatinine (Cr) ratio were significantly higher in the NAWI group. Especially, BUN/Cr ratio shows that the NAWI group reached dehydration status. Older age (adjusted odd ratio, OR=1.07, 95% confidence interval, CI [1.04–1.10]), female gender (adjusted OR=1.56, 95% CI [1.05–2.33]), lower body mass index (BMI) (adjusted OR=1.00, 95% CI [0.92–1.00]), higher BUN (adjusted OR=1.04, 95% CI [1.01–1.08]), and higher urine specific gravity (USG) (adjusted OR=1.56, 95% CI [1.19–2.05]) were factors associated with the NAWI group. CONCLUSION: The findings suggest that the level of water intake needs to be considered in relation to age, gender, BMI, BUN, and USG. These are sensitive physiological parameters used for predicting dehydration of the elderly according to their daily oral water intake. It would be helpful to develop strategies to prevent dehydration in elderly individuals and enhance their water intake.

The Relationship of Water Intake and Health Status in Korean Adult: 5th Korea National Health and Nutrition Examination Survey / 계명의대학술지

BACKGROUND: Water is essential to body homeostasis. But there are little attention to basic impact or attribute of response to drinking water. We investigated the factors related to drinking water through the ‘5th Korea National Health and Nutrition Examination Survey’ (KNHANESV). METHODS: From the database of the 5th KNHANESV conducted in 2010 to 2012, data of 15,716 adults who aged 19 or above, and responded to all the questionnaires of health interview, nutrition survey and had health examination were included in this analysis. SPSS 21.0 was used for statistical analysis with complex sample survey modules. RESULTS: The study subjects drink 5.2 ± 0.48 cups of water for a day. The elderly (>65 yrs) drink less water (p < 0.000), and male drink more than female (p < 0.000). And obesity is significantly associated with higher water intake (p < 0.000). Calorie and sodium intake, HbA1c, low-density lipoprotein, triglyceride, feritin, Fe, creatinine are significantly associated with higher water intake. Physical activity and serum vitamin D level are also associated with higher water intake (p < 0.000). CONCLUSION: Older people drink less water and several disease is related with water intake amount. Further studies need to be done about the value of water intake in healthy life style, and measuring the effect of water intake.

Effect of Oral Water Intake to Globus Pharyngeus with Non-Organic Diseases

BACKGROUND AND OBJECTIVES: Globus pharyngeus is a sensation of foreign body in the throat. There are many studies evaluate relationships between globus pharyngeus and organic diseases such as laryngopharyngeal reflux, esophageal motility disorders as well as psychotic causes. But, Also many patients without etiologic causes complain of globus sensation. The authors performed a study that evaluate association between oral water intake and symptoms of globus sensation on the basis of a belief that pharyngeal dehydration due to lack of oral water intake causes globus sensation. MATERIALS AND METHODS: A survey using visual analogue scale to evaluate symptoms was performed with 73 patients with globus pharyngeus. RESULTS: Patients who drink water less than 500 mL per day (p=0.04) and less than five times per day (p=0.02) were improved after 6 months due to education and doctor's recommendation. CONCLUSION: Frequent and enough water intake should be recommended to resolve symptoms of globus sensation.

Establishment of reference intake of water for Korean adults in 2015 / 한국영양학회지

PURPOSE: This review was performed to establish a reference intake of water for Korean (KDRI-water) adults in 2015 by examining current knowledge of the relationship between water intake and health and the general status of water intake and loss. We expect that this study will be utilized for further refinement of KDRI-water. METHODS: Documents were searched using RISS, NDSL, DBPIA, CINAHL, and Pubmed with the keywords ‘water intake, water supply, water ingestion, hydration, dehydration, water balance, and fluid balance’. RESULTS: Water balance is essential for the maintenance of health. Based on this assumption, numerous studies have been performed to investigate the association of water intake with several diseases such as urolithasis, obesity, diabetes, and cancer as well as other health problems, including constipation, cognition, and fetal weight. Effects of water intake for prevention or relief of these health problems vary. Water is supplied to the body by eating foods and drinking liquids such as plain water and beverages. Metabolic water is another source of water input. Water is lost through urine, skin, respiration, and feces. KDRI-water 2015 was set by adequate intake (AI) based on water intake volume, which was the sum of water intakes from foods and fluids reported by the Korea National Health and Nutrition Examination Survey, with extra milk intake of 200 mL. AIs in some age groups were modified considering their estimated energy requirements. CONCLUSION: Accurate data of water intake is critically important for the establishment of KDRI-water. Therefore, improvement of systems investigating water intake is required, and more studies on the status of water intake and loss in Korean people are needed for definite KDRI-water establishment.

Balanço hídrico e excreção renal de metabólitos em ovinos alimentados com palma forrageira (Nopalea cochenillifera Salm Dyck) / Water balance and renal excretion of metabolites in sheep fed forage cactus (Nopalea cochenillifera Salm Dyck)

Objetivou-se avaliar balanço hídrico e excreção renal de metabólitos em borregos sem raça definida, alimentados com diferentes quantidades de palma forrageira (Nopalea cochenillifera Salm Dyck), na forma in natura e em farelo. Foram utilizados 20 borregos, com peso vivo médio inicial de 20 Kg e foram distribuídos no delineamento inteiramente casualizado, sendo cinco tratamentos e quatro repetições. As dietas experimentais consistiram em uma dieta controle à base de feno de tífton, farelo de soja, suplemento mineral e calcário, os demais tratamentos visaram testar níveis diferentes de palma forrageira corrigida com ureia em duas formas: in natura e farelada e em dois níveis de substituição (50 e 100%) da matéria seca do feno de tífton. Amostras de sangue e urina foram coletadas para determinação de diferentes metabólitos e minerais e utilização de equações para obtenção dos índices de excreção urinária destes metabólitos, taxa de depuração endógena de creatinina e reabsorção de água livre de eletrólitos, além do registro de ingestão de água e volume de urina. A ingestão voluntária de água sofreu influência das dietas, sendo que os animais submetidos às dietas contendo farelo de palma e feno e farelo de palma foram superiores aos demais tratamentos. A ingestão de água via alimentos também sofreu influência da dieta, sendo maior nos animais que receberam palma in natura e farelo mais palma in natura. Com relação à ingestão total de água foi maior para os animais alimentados com dietas contendo palma in natura em relação aos demais tratamentos. As dietas experimentais influenciaram na excreção renal de metabólitos derivados purínicos e minerais, sem alterar a função renal. A presença da palma forrageira tanto na condição de farelo como in natura proporciona aumento do volume urinário sem alterar a função renal, além de que deve ser considerado como uma excelente estratégia alimentar no semiárido.

This study aimed to assess fluid balance and renal excretion of metabolites in lambs without defined breed standard, fed different forage cactus (Nopalea cochenillifera Salm Dyck), in natura and bran. 20 lambs were used, with initial body weight of 20 kg and were distributed in a completely randomized design, with five treatments and four repetitions. The experimental diets consisted of a control diet based on Bermuda grass hay, soybean meal, limestone and mineral supplement, other treatments aimed at testing different levels of cactus pear plus urea in two forms: fresh and mash and two levels of substitution (50 and 100%) of dry matter of hay. Blood and urine samples were collected for determination of different metabolites and minerals and use of equations to determine the rates of urinary excretion of these metabolites, rate of endogenous creatinine clearance and electrolyte reabsorption of free water, in addition to recording of water intake and urine volume. The voluntary water intake was influenced by the diets, and the animals subjected to diets containing soybean meal and hay palm and cactus meal were higher than other treatments. Water intake via food was also influenced by diet, being higher in animals fed palm fresh and bran over palm in nature. With respect to total water intake was greater for cows fed diets containing palm in nature compared to the other treatments. The experimental diets influenced the renal excretion of purine metabolites and minerals derived, without changing renal function. The presence of cactus pear both as bran as in nature provides increased urine volume without changing renal function, and to be considered as an excellent food strategy in semiarid.

Involvement of Neuropeptide Orexin B in Basolateral Amygdala Mediated Consummatory Behaviour in Male Wistar Albino Rats.

The basolateral amygdala has been implicated in the regulation of food intake besides the hypothalamic centres. In the present study, we hypothesized that the Orexin B, a polypeptide identified in the lateral hypothalamic region, may be involved in the modification of the functions the of amygdaloid centres. We therefore studied the effect of infusion of Orexin B and its antagonist (TCS-OX2-29) into Basolateral amygdala to study the feeding behaviour. Materials and methods: Adult male Wistar albino rats were selected and grouped into control, sham operated control and experimental groups (n=6 each) Orexin was infused in two doses (3 nmol/μl, 30 nmol/ μl) and TCS-OX2-29(10 μg/μl) was infused in another group. Sequential Food intake and water intake were measured at 1, 2, 4, 6, 12 hours and intake for the day was also recorded in all groups and the results (mean±SEM) were statistically analyzed by Kruskal Wali’s test and p<0.05 was considered significant. Results: The food intake and water intake were significantly increased (p<0.01) in the high dose group though the increase in the low dose treated animals was less. Injection of Orexin B antagonist decreased the food and water intake significantly. Discussion and conclusion: The results suggest that Orexin plays a role in the modulation of feeding behaviour. In the lower doses it did not show significant effect. At higher doses, the effect was marked. The role of orexin in ingestive behaviour is further confirmed by the action of antagonist infusion, which resulted decrease in the feeding activities.

Inquietudes de la población sobre el consumo de agua, sus diferentes tipos y la hidratación / People’s concerns about water intake, beverage categories and hydration

El consumo de agua es fundamental para el ser humano, todo el mundo lo sabe, aunque ¿la población, conoce realmente por qué es necesario? ¿Le gustaría hablar con su médico respecto de las causas por las cuales es nece-sario consumir agua?Objetivos: evaluar la necesidad que tiene la población de consultar con su médico respecto de la importancia del con-sumo de agua.Materiales y métodos: se encargó a la Empresa Ipsos la realización de una encuesta a nivel nacional de 1.000 casos, a individuos de ambos sexos de 18 a 70 años de todos los nive-les socioeconómicos, con representatividad de las principales ciudades, de los cuales el 32% pertenecía al AMBA y el 68% al interior del país.Resultados: el 76% de la población encuestada respondió positivamente a la pregunta: “Si tuviera la posibilidad de ha-blar con un médico o profesional amigo, ¿le preguntaría algo sobre hidratación?”.Las principales inquietudes que mostró la población se en-cuentran ligadas a qué tipo de bebidas consumir (con un 91% de mención), cuáles son los beneficios del agua (con un 82% de mención), qué cantidad se debe ingerir (con un 70% de mención) y la importancia que tiene la cantidad de sodio presente en ella (con un 60% de mención).

It is apparent that there is a significant need of information about the characteristics and necessities of water intake.

The Effect of Long Term Consumption of Powdered Tobacco Diet on Learning and Memory in Swiss White Mice.

Aim: The effects of long term consumption of powdered tobacco (snuff) diet on learning and memory was studied in 30 Swiss white mice. Design: The mice were randomly assigned into two groups (n = 15 each). Mice in group 1 (test group) were fed 1% tobacco diet while mice in the other group (control) were fed normal rodent chow only. Both groups were fed for 31 days before carrying out behavioural testing. All mice were given free access to clean drinking water. Methodology: Food and water consumption by the animals were measured daily while their body weight was measured every two days. The Morris water maze was used to assess Learning and Memory in the mice. Results: The mean daily water and food intake was significantly higher (p<0.01; 0.001 respectively) in the tobacco diet-fed group than in control. The tobacco diet fed group also had a significantly higher (p<0.05) body weight gain than control. The swim latency during the reversal training was shorter in the tobacco diet-fed mice compared to their controls (p<0.01), showing better learning among the tobacco diet-fed group of mice. Southeast (reversal/retention) quadrant duration was also higher in the tobacco diet-fed mice (p<0.01) showing better memory than control. Conclusion: Long term consumption of 1% tobacco diet increased food and water intake, weight gain and improved learning and Memory in mice.

Effect of water intake on postexercise cardiovascular recovery / Efeito da ingestao hidrica sobre a recuperacao cardiovascular pos-exercicio

Physical exercise elicits an increase in heart rate (HR), blood pressure (BP) and, consequently, in the rate-pressure product (RPP). Recovery of HR immediately after exercise indicates cardiovascular health. Blood pressure also decreases after exercise, occasionally reaching values lower than pre-exercise levels (postexercise hypotension). Studies have shown a positive effect of water intake on HR recovery after exercise. However, little is known about the effect of water intake on postexercise BP and RPP responses. The objective of this study was to evaluate the effects of water intake on postexercise cardiac work assessed by HR, BP and RPP. Fourteen healthy volunteers (22 ± 1.4 years) participated in the study. The experimental session consisted of HR, systolic (SBP) and diastolic BP (DBP) recording at rest, followed by submaximal exercise on a cycle ergometer. Next, the subjects consumed water and the cardiovascular variables were recorded during recovery. In addition, a control session without postexercise water intake was performed. The RPP was calculated from the product of HR and SBP. Water intake prevented a postexercise hypotensive effect on DBP, but accelerated postexercise HR and RPP reduction during recovery when compared to the control session. It was concluded that water intake is an effective strategy to reduce postexercise cardiac work.

O exercício físico promove a elevação da frequência cardíaca (FC), pressão arterial (PA) e, por consequência, do duplo produto (DP). Imediatamente após o término do exercício, há a recuperação da FC; resposta que indica boa saúde cardiovascular. A PA também apresenta queda pós-exercício, atingindo, eventualmente, valores abaixo do repouso (hipotensão pós-exercício; HPE). Estudos têm demonstrado efeito positivo da ingestão hídrica (IH) sobre a recuperação da FC pós-exercício. Pouco se sabe a respeito do efeito dessa estratégia sobre o comportamento da PA e do DP nesse período. O objetivo do estudo foi investigar o efeito da IH sobre o trabalho cardiovascular pós-exercício, por meio da avaliação da FC, PA e DP. Quatorze voluntários saudáveis (22 ± 1,4 anos) participaram desse estudo. A sessão experimental constou do registro da FC e PA sistólica (PAS) e diastólica (PAD) de repouso, seguido de exercício físico submáximo em cicloergômetro. Posteriormente, realizou-se a IH e registro das variáveis cardiovasculares na recuperação. Adicionalmente, realizou-se uma sessão controle, excluindo-se a IH pós-exercício. O DP foi calculado a partir do produto da FC pela PAS. A IH impediu a ocorrência de HPE na PAD, porém acelerou a redução da FC e do DP, no período da recuperação pós-exercício, quando comparada à sessão controle. Pode-se concluir que a IH é uma estratégia eficiente na redução do trabalho cardiovascular pós-exercício.

Presence of multiple peripheral circadian oscillators in the tissues controlling voiding function in mice

Circadian clocks are the endogenous oscillators that harmonize a variety of physiological processes within the body. Although many urinary functions exhibit clear daily or circadian variation in diurnal humans and nocturnal rodents, the precise mechanisms of these variations are as yet unclear. In the present study, we demonstrate that Per2 promoter activity clearly oscillates in neonate and adult bladders cultured ex vivo from Per2::Luc knock-in mice. In subsequent experiments, we show that multiple local oscillators are operating in all the bladder tissues (detrusor, sphincter and urothelim) and the lumbar spinal cord (L4-5) but not in the pontine micturition center or the ventrolateral periaqueductal gray of the brain. Accordingly, the water intake and urine volume exhibited daily and circadian variations in young adult wild-type mice but not in Per1-/- Per2-/- mice, suggesting a functional clock-dependent nature of the micturition rhythm. Particularly in PDK mice, the water intake and urinary excretion displayed an arrhythmic pattern under constant darkness, and the amount of water consumed and excreted significantly increased compared with those of WT mice. These results suggest that local circadian clocks reside in three types of bladder tissue and the lumbar spinal cord and may have important roles in the circadian control of micturition function.

Plain water intake of Korean adults according to life style, anthropometric and dietary characteristic: the Korea National Health and Nutrition Examination Surveys 2008-2010

BACKGROUND/OBJECTIVES: The objective of the study was to provide useful insights into plain water intake of Korean adults according to life style, anthropometric, and dietary characteristics. SUBJECTS/METHODS: The data from the 2008-2010 Korea National Health and Nutrition Examination Survey were used. The subjects were 14,428 aged 20-64 years. Water intake was estimated by asking the question "How much water do you usually consume per day?". Dietary intake was estimated by 24-hour dietary recall. A qualitative food frequency questionnaire including 63 food items was also administered. RESULTS: The mean plain water intake for men and women were 6.3 cup/day and 4.6 cup/day, respectively. Plain water intake increased as lean body mass, waist circumference, and body mass index levels increased, except for percentage of body fat. As energy and alcohol intakes increased, plain water intake increased. As total weight of food intake and total volume of food intake increased, plain water intake increased. Plain water intake increased as consumption of vegetables increased. Plain water intake increased as frequencies of green tea, alcoholic drink, and all beverages were increased in men. Plain water intake increased with increased frequencies of green tea, milk, soy milk, and alcoholic drink and decreased frequencies of coffee and soda in women. CONCLUSIONS: Our results suggest that persons who had a higher waist circumference or lean body mass and women with higher BMI consumed more plain water. The persons eating high quality diet, or the persons who had more vegetables, green tea, milk, soy milk, or alcoholic drink consumed more plain water.
