Although many epidemiological studies on sexuality have been published, none have specifically addressed male and female sexuality in repartnered couples. Aim. To investigate men and women’s sexual behaviors, perceptions and expectations, and the frequency of their sexual dysfunctions, with a focus on repartnered couples, i.e, subjects living with a partner in a stable relationship after divorce or widowhood (including both remarried couples and cohabitating unmarried couples). Methods. Analysis of telephone survey data collected from 1,002 French subjects (483 men, 519 women) ≥35years. Of these, 748 were living with their partner as part of a heterosexual couple. For these subjects, the sexuality of 149 repartnered subjects was compared to that of the other 599 subjects. Main Outcome Measures. A 39-item questionnaire assessing subjects' perceptions, expectations, sexual behaviors and dysfunctions. Results. Compared with other subjects, men and women in repartnered couples had more active sexuality and more interest in sexuality (men 93% vs 80%, P < 0.01, women 73% vs 65%, P < 0.05). They were generally more sensitive to feelings and emotions linked to their sexuality, and these feelings seemed to increase steadily with age. Their sexuality was more attuned to their partner’s pleasure (men 79% vs. 59% P < 0.001, women 50% vs. 34% P < 0.01). Concern for the future of the relationship and for sexuality was equally present for both groups, although repartnered couples were more often concerned about potential inadequacy and conflicts between the two partners. Although repartnered men seemed to be less affected by diminished desire, they had slightly higher rates of premature ejaculation and erectile dysfunction, and considered their quality of life to be more affected by these problems. Conclusion. The sexuality of repartnered couples remains poorly studied, but seems to differ from that of non-repartnered couples. Our findings open interesting avenues of research on the diagnosis and management of repartnered couples.展开更多

Persons with diabetes have a higher incidence of cognitive decline and an increased risk of developing all types of dementia. Cognitive deficits in persons with diabetes mainly affect the areas of psychomotor efficiency, attention, learning and memory, mental flexibility and speed, and executive function. The strong epidemiological association has suggested the existence of a physiopathological link. The determinants of the accelerated cognitive decline in DM2, however, are less clear. Increased cortical and subcortical atrophy have been evidenced after controlling for diabetic vascular disease and inadequate cerebral circulation. Most recent studies have focused on the role of insulin and insulin resistance as possible links between diabetes and AD. Disturbances in brain insulin signaling mechanisms may contribute to the molecular, biochemical, and histopathological lesions in AD. Hyperglycemia itself is a risk factor for cognitive dysfunction and dementia. Hypoglycemia may also have deleterious effects on cognitive function. Recurrent symptomatic and asymptomatic hypoglycemic episodes have been suggested to cause sub-clinical brain damage, and permanent cognitive impairment. Futuretrials are required to clarify the mechanistic link, to address the question whether cognitive decline may be prevented by an adequate metabolic control, and to elucidate the role of drugs that may cause hypoglycemic episodes.展开更多

Although high-volume polyethylene glycol(PEG) solution is the most frequently used preparation for bowel cleansing, patients are often unwilling to take PEG solution due to its large volume, poor palatability, and high incidence of adverse events, such as abdominal bloating and nausea. Other purgatives include osmotic agents(e.g., sodium phosphate, magnesium citrate, and sodium sulfate), stimulant agents(e.g., senna, bisacodyl, and sodium picosulfate), and prokinetic agents(e.g., cisapride, mosapride, and itopride). A combination of PEG with an osmotic, stimulant, or prokinetic agent could effectively reduce the PEG solution volume and increase patients' adherence. Some such solutions have been found in several published studies to not be inferior to PEG alone in terms of bowel cleansing quality. Although combination methods showed similar efficacy and safety, the value of these studies is limited by shortcomings in study design. New effective and well-tolerated combination preparations are required, in addition to rigorous new validated studies.展开更多

The most ideal and reasonable rescue option involves early suspicion and identification of patients with inadequate preparation before sedation, additional oral ingestion of a suitable preparation formulation, and same-day colonoscopy.AIM To compare 0.5-L and 1-L polyethylene glycol containing ascorbic acid(PEG +Asc) as additional bowel cleansing methods after a 2-L split-dose PEG + Asc regimen in patients with expected inadequate bowel preparation before colonoscopy.METHODS Individuals with expected inadequate bowel preparation based on last stool form, such as turbid liquid, particulate liquid, or liquid with small amounts of feces, were randomized to either a 0.5-L PEG + Asc group or a 1-L PEG + Asc group. The primary endpoint was bowel preparation as assessed using the Aronchick bowel preparation scale(ABPS) and Boston bowel preparation scale(BBPS) scores. The secondary endpoints were cecal intubation time, withdrawal time, polyp detection rate(PDR), adenoma detection rate(ADR), individual compliance with additional PEG + Asc, and patient satisfaction.RESULTS Initially, 98 patients were included, but 8 were later excluded due to withdrawal of consent to participate in the study. Adequate bowel preparation(as assessed by ABPS) was observed in 80.9%(38/47) of subjects in the 0.5-L group and in88.4%(38/43) of subjects in the 1-L group(P = 0.617). Mean total BBPS was 6.7 points in the 0.5-L group and 7.0 points in the 1-L group(P = 0.458). ADRs and PDRs were similar in the two groups, and cecal intubation and withdrawal times were not significantly different. However, mean patient satisfaction score was significantly higher in the 0.5-L group(P = 0.041).CONCLUSION The bowel cleaning efficacy of additional 0.5-L PEG + Asc was not inferior to that of 1-L PEG + Asc. Additional 0.5-L PEG + Asc is worthwhile when inadequate bowel preparation is expected before colonoscopy.展开更多

In this study 418 adults (18 to 60 years) from 15 Spanish provinces were studied. Energy and nutrient intake was determined using a 24-hour recall questionnaire for two days. Adequacy of calcium intake was assessed using the established DRI for calcium. Anthropometric data (weight and height) were measured and the body mass index was calculated. Seventy eight percent of the participants in the study did not meet the DRI for calcium. Additionally, 33.7% of the participants did not meet the 67% of the DRI. The daily intake of calcium was 916.6 ± 288.1 mg/day, which represented the 81.3% of the DRI of calcium. Interestingly, subjects who had higher intake of calcium were taller. Additionally, it has been observed that individuals with normal body weight (BMI 2) had higher intakes of dairy products in comparison with overweight and obese individuals (BMI ≥ 25 kg/m2). The main food sources of calcium were dairy products (58.7% of calcium), cereals (13.6%) and vegetables (6.5%). Less than 1% (0.5%) of the calcium intake came from dietary supplements. It was observed that individuals who met the DRI for calcium had a significantly higher intake of dairy products (551.3 ± 240.4 g/day) than individuals who did not meet the DRI of calcium (305.0 ± 150.3 g/day). Calcium intake was inadequate in this sample of the adult Spanish population. Therefore, an increase in the consumption of dairy products, as well as cereals, vegetables and food items fortified with calcium seems to be necessary to achieve an adequate intake of calcium and to prevent diseases caused by calcium deficiency.展开更多

The study conducted a stochastic assessment of the risk of infection linked to the consumption of braised beef meat “Choukouya” contaminated by Clostridium perfringens in C?te d’Ivoire. We conducted “Choukouya” consumers (n = 900) and vendors (n = 300) survey to characterize the actors behavior. 189 samples of “Choukouya” were collected and microbiologically analyzed according to French standard protocols NF V 08-061 and XPV 08-061. A risk model was developed and the risk of infection linked to the consumption of “Choukouya” was estimated by Monte Carlo simulation procedure. The consumer’s surveys showed that the percentage of population consuming “Choukouya” was 74.4%, with an average consumption of 114.3 ± 0.5 g/person/intake. The microbiological analysis revealed the isolation of 70% of Clostridium perfringens in the vegetative form and 60.3% in sporulated form with an average loading of 3.7 ± 2.6 log10·cfu/g and 1.1 ± 1.0 log10·cfu/g respectively. The probability of ingesting a dose greater than 109 bacteria of Clostridium prefringens varied between 7.36% and 7.93%. The braised beef meat “Choukouya” sold in the streets of cities in C?te d’Ivoire represents a real risk of infection, and Clostridium perfringens is one of the causes. This risk could be mitigated by the establishment of good hygiene practices and adequate handling processes in this informal sector.展开更多

Many struggle to integrate the priorities of their academic and clinical missions. Previous studies have documented increasing need for monetary institutional support of academic anesthesia departments. In view of current economic and legislative circumstances, it is arguable that the need for support will grow. This survey demonstrates that staffing issues, which are most likely engendered by financial circumstances, have impacted academic anesthesia departments in the United States to the point of having deleterious effects upon clinical safety and resident education.Methods: After IRB approval, we electronically solicited the anonymous response to a 23 question survey from all 133 chairpersons of academic anesthesia departments in the United States. Results: Sixty-two responded electronically, for an overall response rate of 46.6%. Conclusion: The results of this survey suggest that academic anesthesia departments are being financially stressed to the point that education and patient care are affected.展开更多

An adequate level of IgG measured in all calves at 48 hours, 7 days and 14 days after birth showed level of IgG 1000 mg/dl. This level indicated that they have good passive transfer of immunity. Also, in this study colostrum quality fed to calves was detected using Brix Refractometer. The colostrum is of high quality as it contains 50 mg/ml of IgG. This Brix refractometer can be used on the farm level to estimate colostrum IgG content and monitoring colostrum feeding practices. Colostrum with high quality IgG could provide calves with enough IgG to attain successful passive transfer of immunity. Brix and Obione refractometers provide simple, rapid method for estimating IgG concentration on calf serum, thus considered to be the most common method for determining passive transfer failure.展开更多

Several techniques have been suggested in the literature to increase inadequte bone width which includes bone grafting, distraction osteogenesis and bone expansion. Bone expansion technique is one of the most widely used methods which can also be utilized to increase the width of alveolar ridge and to provide sufficient bone volume for implant placement. The purpose of this study, is to measure the increase of the width of alveolar ridge after bone expansion following implant placement. Between 2013-2016, 30 consecutive, healthy, non-smoking, adult patients with atrophy of the maxilla and mandibula had 149 implants inserted. There were 18 women and 12 men, mean age 51.34 years (range 34 - 67). The initial width of the alveolar ridge measured from 2.5 to 3 mm (mean 2.83 ± 0.2) with Cone beam computed tomography (CBCT). The mean increase of bone width was achieved 1.25 mm (between 0.64 mm and 1.73 mm). Before prosthetic rehabilitation, width of expanded alveolar bone was calculated from 3.50 to 4.75 mm with CBCT. During follow-up, 140 implants survived and 9 implants failed. The rate of implant survival was 93.95% after average 5 years follow-up. In conclusion, we suggest that, bone expansion is useful for managing the unsufficient ridges for implant placement.展开更多

Whereas some aggregate indicators have shown improvement over the year, the cumulative growth rates in consumption and fixed asset investment have continued theirdownward trajectories. Worsening income inequality and resource misallocations, both between secondary and tertiary industries, and within the latter, pose serious challenges, let alone the systemic risk associated with the flourishing shadow banking system, rapid credit growth and debt overhang that weigh on the Chinese economy like the Sword of Damocles. This summary report highlights both the status quo and the consequences of the unbalanced and inadequate development embodied in China's persistently distorted economic structure, and the role of deepening reforms of the institutions and governance in resolving the problems. Our analyses based on IAR-CMM model provide a unified framework for addressing China's short-, medium-, and long-term issues ir~ an internally coherent manner. Looking into year 2018, our benchmark projection of real GDP growth rate is 6.7% (6.41% using more reliable rather than the official data). Alternative scenario analyses and policy simulations are conducted to reflect various aspects of the economic challenges in the short to long runs. Through the lens of these analyses we conclude that rule-of-law based and market-oriented structural reforms should continue to hold a center stage in China's transition from a phase of high-speed but unbalanced growth, to a stage of balanced and adequate high-quality development.展开更多

文摘BACKGROUND No consensus has been reached in patients suspected of having inadequate bowel preparation regarding optimal salvage methods, which negatively affects the efficacy and quality of colonoscopy. The most ideal and reasonable rescue option involves early suspicion and identification of patients with inadequate preparation before sedation, additional oral ingestion of a suitable preparation formulation, and same-day colonoscopy.AIM To compare 0.5-L and 1-L polyethylene glycol containing ascorbic acid(PEG +Asc) as additional bowel cleansing methods after a 2-L split-dose PEG + Asc regimen in patients with expected inadequate bowel preparation before colonoscopy.METHODS Individuals with expected inadequate bowel preparation based on last stool form, such as turbid liquid, particulate liquid, or liquid with small amounts of feces, were randomized to either a 0.5-L PEG + Asc group or a 1-L PEG + Asc group. The primary endpoint was bowel preparation as assessed using the Aronchick bowel preparation scale(ABPS) and Boston bowel preparation scale(BBPS) scores. The secondary endpoints were cecal intubation time, withdrawal time, polyp detection rate(PDR), adenoma detection rate(ADR), individual compliance with additional PEG + Asc, and patient satisfaction.RESULTS Initially, 98 patients were included, but 8 were later excluded due to withdrawal of consent to participate in the study. Adequate bowel preparation(as assessed by ABPS) was observed in 80.9%(38/47) of subjects in the 0.5-L group and in88.4%(38/43) of subjects in the 1-L group(P = 0.617). Mean total BBPS was 6.7 points in the 0.5-L group and 7.0 points in the 1-L group(P = 0.458). ADRs and PDRs were similar in the two groups, and cecal intubation and withdrawal times were not significantly different. However, mean patient satisfaction score was significantly higher in the 0.5-L group(P = 0.041).CONCLUSION The bowel cleaning efficacy of additional 0.5-L PEG + Asc was not inferior to that of 1-L PEG + Asc. Additional 0.5-L PEG + Asc is worthwhile when inadequate bowel preparation is expected before colonoscopy.

文摘The present study aimed to assess calcium intake, dietary sources of this nutrient and its adequacy with respect to the dietary reference intake (DRI) in a representative sample of Spanish adults. In this study 418 adults (18 to 60 years) from 15 Spanish provinces were studied. Energy and nutrient intake was determined using a 24-hour recall questionnaire for two days. Adequacy of calcium intake was assessed using the established DRI for calcium. Anthropometric data (weight and height) were measured and the body mass index was calculated. Seventy eight percent of the participants in the study did not meet the DRI for calcium. Additionally, 33.7% of the participants did not meet the 67% of the DRI. The daily intake of calcium was 916.6 ± 288.1 mg/day, which represented the 81.3% of the DRI of calcium. Interestingly, subjects who had higher intake of calcium were taller. Additionally, it has been observed that individuals with normal body weight (BMI 2) had higher intakes of dairy products in comparison with overweight and obese individuals (BMI ≥ 25 kg/m2). The main food sources of calcium were dairy products (58.7% of calcium), cereals (13.6%) and vegetables (6.5%). Less than 1% (0.5%) of the calcium intake came from dietary supplements. It was observed that individuals who met the DRI for calcium had a significantly higher intake of dairy products (551.3 ± 240.4 g/day) than individuals who did not meet the DRI of calcium (305.0 ± 150.3 g/day). Calcium intake was inadequate in this sample of the adult Spanish population. Therefore, an increase in the consumption of dairy products, as well as cereals, vegetables and food items fortified with calcium seems to be necessary to achieve an adequate intake of calcium and to prevent diseases caused by calcium deficiency.
文摘Inadequate handling, processing and sales of meat products have resulted in microbial contamination responsible for most infectious human food-borne illness. The study conducted a stochastic assessment of the risk of infection linked to the consumption of braised beef meat “Choukouya” contaminated by Clostridium perfringens in C?te d’Ivoire. We conducted “Choukouya” consumers (n = 900) and vendors (n = 300) survey to characterize the actors behavior. 189 samples of “Choukouya” were collected and microbiologically analyzed according to French standard protocols NF V 08-061 and XPV 08-061. A risk model was developed and the risk of infection linked to the consumption of “Choukouya” was estimated by Monte Carlo simulation procedure. The consumer’s surveys showed that the percentage of population consuming “Choukouya” was 74.4%, with an average consumption of 114.3 ± 0.5 g/person/intake. The microbiological analysis revealed the isolation of 70% of Clostridium perfringens in the vegetative form and 60.3% in sporulated form with an average loading of 3.7 ± 2.6 log10·cfu/g and 1.1 ± 1.0 log10·cfu/g respectively. The probability of ingesting a dose greater than 109 bacteria of Clostridium prefringens varied between 7.36% and 7.93%. The braised beef meat “Choukouya” sold in the streets of cities in C?te d’Ivoire represents a real risk of infection, and Clostridium perfringens is one of the causes. This risk could be mitigated by the establishment of good hygiene practices and adequate handling processes in this informal sector.
文摘Background: Academic anesthesia departments are under increasing financial pressure. Many struggle to integrate the priorities of their academic and clinical missions. Previous studies have documented increasing need for monetary institutional support of academic anesthesia departments. In view of current economic and legislative circumstances, it is arguable that the need for support will grow. This survey demonstrates that staffing issues, which are most likely engendered by financial circumstances, have impacted academic anesthesia departments in the United States to the point of having deleterious effects upon clinical safety and resident education.Methods: After IRB approval, we electronically solicited the anonymous response to a 23 question survey from all 133 chairpersons of academic anesthesia departments in the United States. Results: Sixty-two responded electronically, for an overall response rate of 46.6%. Conclusion: The results of this survey suggest that academic anesthesia departments are being financially stressed to the point that education and patient care are affected.

文摘The principal contradiction facing the Chinese society has evolved to be that between imbalanced and inadequate development and the people’s ever-growing needs for a better life.Given China’s vision for achieving moderate prosperity,it is relevant to conduct theoretical and empirical studies on the nation’s development imbalances.As a quantitative index,the Tsinghua China Balanced Development Index measures the extent to which development is uneven and insuf ficient across regions,re flecting the progress and shortfalls in China’s efforts to promote balanced development.Our findings provide implications for how policymakers may help people’s expectations for a better life materialize by spurring balanced economic,social,environmental and livelihood development across regions.
文摘IgG Check calf test has been used in this study to identify if a failure of passive transfer occurs in neonatal calves by measuring the level of IgG in blood. An adequate level of IgG measured in all calves at 48 hours, 7 days and 14 days after birth showed level of IgG 1000 mg/dl. This level indicated that they have good passive transfer of immunity. Also, in this study colostrum quality fed to calves was detected using Brix Refractometer. The colostrum is of high quality as it contains 50 mg/ml of IgG. This Brix refractometer can be used on the farm level to estimate colostrum IgG content and monitoring colostrum feeding practices. Colostrum with high quality IgG could provide calves with enough IgG to attain successful passive transfer of immunity. Brix and Obione refractometers provide simple, rapid method for estimating IgG concentration on calf serum, thus considered to be the most common method for determining passive transfer failure.

文摘The placement of implants in edentulous areas is often compromised because of atrophic alveolar ridges. Several techniques have been suggested in the literature to increase inadequte bone width which includes bone grafting, distraction osteogenesis and bone expansion. Bone expansion technique is one of the most widely used methods which can also be utilized to increase the width of alveolar ridge and to provide sufficient bone volume for implant placement. The purpose of this study, is to measure the increase of the width of alveolar ridge after bone expansion following implant placement. Between 2013-2016, 30 consecutive, healthy, non-smoking, adult patients with atrophy of the maxilla and mandibula had 149 implants inserted. There were 18 women and 12 men, mean age 51.34 years (range 34 - 67). The initial width of the alveolar ridge measured from 2.5 to 3 mm (mean 2.83 ± 0.2) with Cone beam computed tomography (CBCT). The mean increase of bone width was achieved 1.25 mm (between 0.64 mm and 1.73 mm). Before prosthetic rehabilitation, width of expanded alveolar bone was calculated from 3.50 to 4.75 mm with CBCT. During follow-up, 140 implants survived and 9 implants failed. The rate of implant survival was 93.95% after average 5 years follow-up. In conclusion, we suggest that, bone expansion is useful for managing the unsufficient ridges for implant placement.

文摘Leaving year 2017 China's macroeconomy is continuously characterized by unbalanced and inadequate development. Whereas some aggregate indicators have shown improvement over the year, the cumulative growth rates in consumption and fixed asset investment have continued theirdownward trajectories. Worsening income inequality and resource misallocations, both between secondary and tertiary industries, and within the latter, pose serious challenges, let alone the systemic risk associated with the flourishing shadow banking system, rapid credit growth and debt overhang that weigh on the Chinese economy like the Sword of Damocles. This summary report highlights both the status quo and the consequences of the unbalanced and inadequate development embodied in China's persistently distorted economic structure, and the role of deepening reforms of the institutions and governance in resolving the problems. Our analyses based on IAR-CMM model provide a unified framework for addressing China's short-, medium-, and long-term issues ir~ an internally coherent manner. Looking into year 2018, our benchmark projection of real GDP growth rate is 6.7% (6.41% using more reliable rather than the official data). Alternative scenario analyses and policy simulations are conducted to reflect various aspects of the economic challenges in the short to long runs. Through the lens of these analyses we conclude that rule-of-law based and market-oriented structural reforms should continue to hold a center stage in China's transition from a phase of high-speed but unbalanced growth, to a stage of balanced and adequate high-quality development.
