Osmostress enhances activating phosphorylation of Hog1 MAP kinase by mono-phosphorylated Pbs2 MAP2K.

The MAP kinase (MAPK) Hog1 is the central regulator of osmoadaptation in yeast. When cells are exposed to high osmolarity, the functionally redundant Sho1 and Sln1 osmosensors, respectively, activate the Ste11-Pbs2-Hog1 MAPK cascade and the Ssk2/Ssk22-Pbs2-Hog1 MAPK cascade. In a canonical MAPK cascade, a MAPK kinase kinase (MAP3K) activates a MAPK kinase (MAP2K) by phosphorylating two conserved Ser/Thr residues in the activation loop. Here, we report that the MAP3K Ste11 phosphorylates only one activating phosphorylation site (Thr-518) in Pbs2, whereas the MAP3Ks Ssk2/Ssk22 can phosphorylate both Ser-514 and Thr-518 under optimal osmostress conditions. Mono-phosphorylated Pbs2 cannot phosphorylate Hog1 unless the reaction between Pbs2 and Hog1 is enhanced by osmostress. The lack of the osmotic enhancement of the Pbs2-Hog1 reaction suppresses Hog1 activation by basal MAP3K activities and prevents pheromone-to-Hog1 crosstalk in the absence of osmostress. We also report that the rapid-and-transient Hog1 activation kinetics at mildly high osmolarities and the slow and prolonged activation kinetics at severely high osmolarities are both caused by a common feedback mechanism.

Trends in East Asian nurses recognizing ethical behavioral practices.

BACKGROUND: Nurses are expected to make and implement autonomous decisions to provide patients with excellent quality nursing while practicing complex, high-level care. However, studies have shown that nursing practice based on autonomous decision-making is difficult, and a gap exists between decision-making and implementation. RESEARCH QUESTION/AIM/OBJECTIVES: This study aims to clarify trends among nursing professionals who recognize they are practicing ethical behavior in their nursing practice. RESEARCH DESIGN/PARTICIPANTS AND RESEARCH CONTEXT: We surveyed the basic attributes of and used the Ode's Ethical Behavior Scale for Nurses with 3467 nursing professionals working at 34 hospitals in suburban cities of Japan and investigated the relationships among these factors. ETHICAL CONSIDERATIONS: This study was approved by the appropriate research ethics committee. The Ethical Behavior Scale for Nurses was used with the authors' permission. FINDINGS/RESULTS: Significant differences were found in the mean "ethical behavior" scores between nurses and licensed practical nurses and midwives and licensed practical nurses. Mean scores for the "justice" subscale differed significantly between the low experience group and mid-level experience group and between the high experience group and mid-level experience group. Significant differences were also found in the mean scores between those with ethics education experience and those without, those with ethics training experience and those without, and those with ethics conference experience and those without. DISCUSSION: Midwives and nurses had higher ethical behaviors than licensed practical nurses. Nursing professionals with low and high experience had higher justice scores than those with mid-level experience. Finally, nursing professionals with ethics education, training, or conference experience had higher ethical behavior than those without such experience. CONCLUSION: Nursing professionals who recognize they are practicing ethical behavior tend to be midwives or nurses with low or high levels of experience who attended ethics education, training, or conferences.

tRNA production links nutrient conditions to the onset of sexual differentiation through the TORC1 pathway.

Target of rapamycin (TOR) kinase controls cell growth and metabolism in response to nutrient availability. In the fission yeast Schizosaccharomyces pombe, TOR complex 1 (TORC1) promotes vegetative growth and inhibits sexual differentiation in the presence of ample nutrients. Here, we report the isolation and characterization of mutants with similar phenotypes as TORC1 mutants, in that they initiate sexual differentiation even in nutrient-rich conditions. In most mutants identified, TORC1 activity is downregulated and the mutated genes are involved in tRNA expression or modification. Expression of tRNA precursors decreases when cells undergo sexual differentiation. Furthermore, overexpression of tRNA precursors prevents TORC1 downregulation upon nitrogen starvation and represses the initiation of sexual differentiation. Based on these observations, we propose that tRNA precursors operate in the S. pombe TORC1 pathway to switch growth mode from vegetative to reproductive.

Muscarinic M1 receptors stimulated by intracerebroventricular administration of McN-A-343 reduces the nerve injury-induced mechanical hypersensitivity via GABAB receptors rather than GABAA receptors in mice.

Cholinergic neurons play an important role in the higher functions of the brain, such as the memory, cognition, and nociception. However, the exact mechanism behind how the stimulation of all the muscarinic M1 receptors in the entire brain results in the alleviation of partial sciatic nerve ligation (PSNL)-induced mechanical hypersensitivity has not been investigated. Thus, we examined which subtype of GABA receptor was involved in the alleviation of PSNL-induce mechanical hypersensitivity produced by an intracerebroventricular administration of a muscarinic M1 receptor agonist, McN-A-343. Administering a GABAA receptor antagonist, bicuculline, resulted in no changes to the McN-A-343-induced anti-hypersensitivity in PSNL mice whereas a GABAB receptor antagonist, CGP35348, dose-dependently inhibited the anti-hypersensitivity. Furthermore, CGP35348 increased mechanical hypersensitivity in naïve mice, and the hypersensitivity was blocked by NMDA receptor antagonists, MK-801 and D-AP5. Additionally, muscarinic M1 receptors colocalized with GABAB1 receptors and an NMDA receptor subunit, GluN2A, in a large region of the brain. Consequently, these results suggest that the activation of muscarinic M1 receptors in the entire brain reduces nerve injury-induced mechanical hypersensitivity via the GABAB receptors, and the activation of the GABAB receptors regulates glutamatergic transmission via NMDA receptors.

Nutrition-related factors associated with waiting list mortality in patients with interstitial lung disease: A retrospective cohort study.

Japanese patients with interstitial lung disease (ILD) sometimes die waiting for lung transplantation (LTx) because it takes about 2 years to receive it in Japan. We evaluated nutrition-related factors associated with waiting list mortality. Seventy-six ILD patients were hospitalized in Kyoto University Hospital at registration for LTx from 2013 to 2015. Among them, 40 patients were included and analyzed. Patient background was as follows: female, 30%; age, 50.3 ± 6.9 years; body mass index, 21.1 ± 4.0 kg/m2 ; 6-minute walk distance (6MWD), 356 ± 172 m; serum albumin, 3.8 ± 0.4 g/dL; serum transthyretin (TTR), 25.3 ± 7.5 mg/dL; and C-reactive protein, 0.5 ± 0.5 mg/dL. Median observational period was 497 (range 97-1015) days, and median survival time was 550 (95% CI 414-686) days. Survival rate was 47.5%, and mortality rate was 38.7/100 person-years. Cox analyses showed that TTR (HR 0.791, 95% CI 0.633-0.988) and 6MWD (HR 0.795, 95% CI 0.674-0.938) were independently correlated with mortality and were influenced by body fat mass and leg skeletal muscle mass, respectively. It is suggested that nutritional markers and exercise capacity are important prognostic markers in waitlisted patients, but further study is needed to determine whether nutritional intervention or exercise can change outcomes.

Effects of fasting on warfarin sensitivity index in patients undergoing cardiovascular surgery.

PURPOSE: Warfarin shows large inter- and intra-individual variabilities in its pharmacokinetics and pharmacodynamics. Sufficient understanding of factors affecting the response to warfarin is necessary to achieve improved outcomes for warfarin therapy. In this study, we evaluated effects of fasting on the anticoagulant properties of warfarin. METHODS: We conducted a retrospective observational study involving a total of 58 patients, who received cardiovascular surgeries and subsequent warfarin therapy. The effect of dietary intake on the anticoagulant properties with warfarin was assessed by measurement of the international normalized ratio of prothrombin time (PT-INR): the anticoagulant activities of warfarin were expressed as the warfarin sensitivity index (WSI). Additionally, fluctuations in WSI during the study period were obtained as differences between the maximum and minimum WSI. RESULTS: The maximum PT-INR and WSI values were significantly higher for patients who were fasting for different reasons during the postoperative period than those in the group without reduced dietary intake. The differences between maximum and minimum WSI in the fasting group significantly increased compared with those in the groups with moderate or no reduced dietary intake. Meanwhile, effects of other markers of clinical conditions including the baseline Child-Pugh score and Charlson Comorbidity Index on WSI were not significant. CONCLUSIONS: Our results indicate that postoperative fasting was significantly associated with the anticoagulation activity of warfarin. In patients fasting for different reasons during the postoperative period, closer control of PT-INR values and warfarin adjustments may be required to avoid adverse effects such as bleeding in warfarin treatment.

Nursing students' understanding of the Fundamentals of Care: A cross-sectional study in five countries.

AIM AND OBJECTIVE: To explore the accuracy with which nursing students can identify the fundamentals of care. BACKGROUND: A challenge facing nursing is ensuring the fundamentals of care are provided with compassion and in a timely manner. How students perceive the importance of the fundamentals of care may be influenced by the content and delivery of their nursing curriculum. As the fundamentals of care play a vital role in ensuring patient safety and quality care, it is important to examine how nursing students identify these care needs. DESIGN: Cross-sectional descriptive design. METHODS: A total of 398 nursing students (pre- and postregistration) from universities in Sweden, England, Japan, Canada and Australia participated. The Fundamentals of Care Framework guided this study. A questionnaire containing three care scenarios was developed and validated. Study participants identified the fundamentals of care for each of the scenarios. All responses were rated and analysed using ANOVA. RESULTS: The data illustrate certain fundamentals of care were identified more frequently, including communication and education; comfort and elimination, whilst respecting choice, privacy and dignity were less frequently identified. The ability to identify all the correct care needs was low overall across the pre- and postregistration nursing programmes in the five universities. Significant differences in the number of correctly identified care needs between some of the groups were identified. CONCLUSIONS: Nursing students are not correctly identifying all a patient's fundamental care needs when presented with different care scenarios. Students more frequently identifying physical care needs and less frequently psychosocial and relational needs. The findings suggest educators may need to emphasise and integrate all three dimensions. RELEVANCE TO CLINICAL PRACTICE: To promote students' ability to identify the integrated nature of the fundamentals of care, practising clinicians and nurse educators need to role model and incorporate all the fundamental care needs for their patients.

The Amount of Fluid Given During Surgery That Leaks Into the Interstitium Correlates With Infused Fluid Volume and Varies Widely Between Patients.

BACKGROUND: The revised Starling law suggests that intravenously infused fluid may leak into the interstitium and not remain in the intravascular space. This hypothesis is supported by clinical findings that postoperative weight gain is proportional to the amount of infused fluid. The distribution of intravenously administered fluid between the interstitium and intravascular space deserves evaluation, as postoperative weight gain because of intraoperative infusion is an important risk factor for postoperative adverse events. We quantitatively estimated fluid movement in patients undergoing orthognathic surgery by performing a volume kinetic study using hemoglobin concentration as a marker of dilution. METHODS: Forty-one patients scheduled to undergo orthognathic surgery were enrolled in this study. The arterial hemoglobin concentration was measured at each procedural step. Acute normovolemic hemodilution was induced by withdrawing 400 mL of blood followed by the infusion of a known amount of hydroxyethyl starch, enabling the initial blood volume to be estimated. The dilution rate of the arterial hemoglobin concentration enabled the volume of fluid in the intravascular space to be quantified. The fluid volume that leaked into the interstitium was then calculated based on the change in the estimated intravascular plasma volume. RESULTS: The blood volume estimated via this method was close to the value derived from a previously published formula. The mean volume of crystalloid infused as a maintenance fluid was 2062 ± 408 mL, ranging from 1220 to 3050 mL. None of the cases required blood product transfusion. The amount of infused fluid that remained intravascular varied widely from 2.0 to 35.7 mL/kg (mean, 12.0 ± 8.2 mL) after surgery, corresponding to 5.3% to 95.7% of the infused volume. The change in intravascular fluid volume during surgery was not strongly correlated with the infusion amount (Pearson correlation analysis: r = -0.05, P = .75, -0.44 < ρ ≤ 0.35, confidence intervals; Spearman correlation analysis: r = -0.14, P = .38, -0.51 < ρ ≤ 0.27). However, the amount of fluid that leaked into the interstitium during surgery did correlate with the infusion amount (Pearson correlation analysis: r = 0.42, P = .01, 0.03 < ρ ≤ 0.70; Spearman correlation analysis: r =0.45, P = .003, 0.07 < ρ ≤ 0.72). CONCLUSIONS: We found that the increase in intravascular fluid volume caused by intravenous fluid administration was not correlated strongly with the volume of infused fluid. Instead, the amount of fluid leakage into the interstitial space depended on the infused fluid volume. This clinical result supports the revised Starling law, which suggests that intravascular fluid may often leak into the interstitium. More work is needed to better understand the factors governing leakage of infused fluid into the interstitial space.

Paternal postnatal depression in Japan: an investigation of correlated factors including relationship with a partner.

BACKGROUND: A negative effect of paternal depression on child development has been revealed in several previous studies. The aims of this study were to examine the prevalence and relevant factors associated with paternal postnatal depression at four months postpartum, including age, part-time work or unemployment, experience of visiting a medical institution due to a mental health problem, economic anxiety, unexpected pregnancy, pregnancy with infertility treatment, first child, partner's depression, and lower marital relationship satisfaction. METHODS: We distributed 2032 self-report questionnaires to couples (one mother and one father) with a 4-month old infant between January and April 2013. Data from 807 couples (39.7 %) were analyzed. Depressive symptoms were measured with the Edinburgh Postnatal Depression Scale (EPDS). In order to clarify the factors related with paternal depression, a logistic regression analysis was conducted. RESULTS: One hundred and ten fathers (13.6 %) and 83 mothers (10.3 %) were depressed. According to the logistic regression analysis, paternal depression was positively associated with partner's depression (adjusted odds ratio (AOR) 1.91, 95 % confidence interval (CI) 1.05-3.47), and negatively with marital relationship satisfaction (AOR 0.83, 95 % CI 0.77-0.89). History of infertility treatment (AOR 2.37, 95 % CI 1.32-4.24), experience of visiting a medical institution due to a mental health problem (AOR 4.56, 95 % CI 2.06-10.08), and economic anxiety (AOR 2.15, 95 % CI 1.34-3.45) were also correlated with paternal depression. CONCLUSIONS: This study showed that the prevalence of paternal depression at four months after childbirth was 13.6 % in Japan. The presence of partner's depression and low marital relationship satisfaction were significantly correlated with paternal postpartum depression, suggesting that health professionals need to pay attention to the mental status of both fathers and mothers, and to their relationship.

Relationship Between Frailty and Diabetic Pharmacologic Therapy in Older Adults with Type 2 Diabetes: A Cross-Sectional Study.

BACKGROUND: Older adults with diabetes mellitus require drug treatment considering their frailty, cognitive function, and hypoglycemia. OBJECTIVE: We investigated the association between diabetic pharmacologic therapy and both diabetic complications and frailty across eight diabetes-specific outpatient clinics nationwide. METHODS: Participants (aged 60-80 years) who had type 2 diabetes and did not require nursing care were included in the study. Basic attributes, patient background, complications, hypoglycemic status, body weight, body composition, blood tests, grip strength, and Kihon Checklist (a frailty index) and self-care scores were obtained. Descriptive statistics, t-test, chi-square test, and regression analyses were employed for evaluation. RESULTS: Overall, 417 participants were included (224 men, 193 women, mean age 70.1 ± 5.4 years, diabetes duration 14.9 ± 10.9 years, body mass index 24.5 ± 3.8, glycated hemoglobin 7.22 ± 0.98%, proportion of individuals with frailty and prefrailty, 19.9% and 41.0%, respectively). All drugs were used more frequently in prefrailty conditions. Each diabetes medication was related to complications, body composition, and frailty, as follows: sulfonylurea (lower hypoglycemia); glinide (severe hypoglycemia, retinopathy, weaker grip strength, high Kihon Checklist score, decreased physical activities); alpha-glucosidase inhibitors (no association); biguanide (high body mass index, high body fat, stronger grip strength); thiazolidinedione (decreased instrumental activities of daily living); dipeptidyl-peptidase-4 inhibitors (no association); sodium-glucose cotransporter 2 inhibitors; retinopathy, high body mass index and Kihon Checklist score, and depressive mood); glucagon-like peptide-1 receptor agonists (high body mass index and body fat and poor nutritional status); and insulin preparations (hypoglycemia, retinopathy, neuropathy, nephropathy, cardiovascular diseases, weaker grip strength, and high Kihon Checklist score and physical inactivity). CONCLUSIONS: Some formulations, such as glinide, sodium-glucose cotransporter 2 inhibitors, and insulin, are associated with an increased frequency of frailty, warranting careful and individualized diabetes treatment.

Optimal Timing of Intravenous Acetaminophen Administration for Postoperative Analgesia.

OBJECTIVE: Acetaminophen (APAP) is widely used as an analgesic for postoperative pain relief. However, the pharmacokinetic-pharmacodynamic (PK-PD) properties of intravenous APAP administration remain unclear. We developed a PK-PD model in adult volunteers. METHODS: APAP (1 g) was intravenously administered to 15 healthy volunteers. The pain equivalent current (PEC) was then measured using the pulse current, corresponding to the quantitative value of pain perception. The PK model was developed using a 2-compartment model, and the PD model was developed using a linear model and an effect compartment model. RESULTS: APAP plasma concentration peaked just administration, whereas PEC significantly increased at 90 minutes and lasted through the experimental period (300 minutes). APAP plasma concentrations and PEC were processed for use in the PK-PD model. The developed PK-PD model delineates the analgesic effect profile, which peaked at 188 minutes and lasted until 327 minutes. CONCLUSION: We developed the PK/PD model for APAP administered intravenously. The analgesic effect can be expected ∼90 minutes after administration and to last >5 hours. It is suggested that APAP be administered ∼90 minutes prior to the onset of anticipated postoperative pain.

Anesthesia Management of a Patient With Familial Cold Autoinflammatory Syndrome: A Case Report.

Familial cold autoinflammatory syndrome (FCAS) is a rare phenotype of cryopyrin-associated periodic syndrome (CAPS) and is characterized by repetitive systemic inflammation triggered by cold stimulation. Recently, we treated a 13-year-old female with FCAS/CAPS scheduled to undergo removal of an impacted tooth. To minimize perioperative heat loss, a forced-air warming system was utilized to prewarm the patient for 10 minutes before induction of general anesthesia. The patient's core and peripheral temperatures were monitored with axillary, superficial temporal artery, and rectal thermometers. The difference in temperatures at these 3 locations decreased to 0.4° C within 60 minutes as a result of the forced-air warming system before induction. Perioperative use of the warming system successfully prevented the occurrence any significant redistribution hypothermia and any symptoms of FCAS/CAPS.

Intrinsic properties and synaptic connectivity of Phox2b-expressing neurons in rat rostral parvocellular reticular formation.

The paired-like homeobox 2b gene (Phox2b) is critical for the development of the autonomic nervous system. We have previously demonstrated the distinct characteristics of Phox2b-expressing (Phox2b+) neurons in the reticular formation dorsal to the trigeminal motor nucleus (RdV), which are likely related to jaw movement regulation. In this study, we focused on Phox2b+ neurons in the rostral parvocellular reticular formation (rPCRt), a critical region for controlling orofacial functions, using 2-11-day-old Phox2b-EYFP rats. Most Phox2b+ rPCRt neurons were glutamatergic, but not GABAergic or glycinergic. Approximately 65 % of Phox2b+ rPCRt neurons fired at a low frequency, and approximately 24 % of Phox2b+ rPCRt neurons fired spontaneously, as opposed to Phox2b+ RdV neurons. Stimulation of the RdV evoked inward postsynaptic currents in more than 50 % of Phox2b+ rPCRt neurons, while only one Phox2b+ rPCRt neuron responded to stimulation of the nucleus of the solitary tract. Five of the 10 Phox2b+ neurons sent their axons that ramified within the trigeminal motor nucleus (MoV). Of these, the axons of the two neurons terminated within both the MoV and rPCRt. Our findings suggest that Phox2b+ rPCRt neurons have distinct electrophysiological and synaptic properties that may be involved in the motor control of feeding behavior.

New model for assembly dynamics of bacterial tubulin in relation to the stages of DNA replication.

How living cells receive their genome through cell division has been one of the important questions of biology. In prokaryotes, cell division starts with formation of a ring-shaped microtubule-like structure, FtsZ-ring, at the potential division site. All the previous models suggested that FtsZ-ring is formed coupling to termination or far after initiation of DNA replication. In contrast, we demonstrated that a close communication with DNA replication is maintained throughout the cell cycle. FtsZ starts to assemble to the cell center coupling to initiation of DNA replication, and stabilizes as FtsZ-ring at its termination, but does not constrict before separation of nucleoids. This combination of a positive and a negative control would guarantee that a successful replication event would inevitably induce one cell division such that each of the daughter cells would receive one and only one daughter nucleoid.

Risk factors of paternal depression in the early postnatal period in Japan.

This study investigated risk factors of depression in fathers at 4 weeks post-partum using a cross-sectional design. Mothers were recruited at the 4 week postnatal health check between March and July 2007. A total of 510 mothers agreed to participate in the study. One-hundred-and-fifty-six fathers and 181 mothers returned the questionnaires. The Edinburgh Postnatal Depression Scale and the Center for Epidemiologic Studies Depression Scale were filled out to assess depressive symptoms. There was no association between paternal and maternal depression. According to the logistic regression analysis, paternal depression was associated with employment status, history of psychiatric treatment, and unintended pregnancy. Of eight fathers with unstable employment, seven were temporary employees and one was unemployed, suggesting that perinatal care-providers should independently screen for depression in fathers and mothers and focus attention on paternal employment status, especially temporary employment.

Nurses' experience in providing care at shelters following natural hazards and disasters: a qualitative systematic review protocol.

OBJECTIVE: The review will synthesize current evidence regarding the experiences of nurses who care for people living in shelters following natural hazards and disasters. INTRODUCTION: Over the last decade, due to climate change and global warming, the damage caused by natural hazards and disasters like hurricanes, floods and heavy rainfall has been steadily growing. Following natural hazards and disasters, many who lose their homes reside in evacuation shelters for prolonged periods. The loss of medical infrastructure in disaster-stricken areas can result in evacuees' health being compromised and the spread of disease and/or infection. Under such circumstances, disaster relief nurses can play a critical role in supporting these victims. This review aims to provide useful information for nurses who are working in disaster shelters. INCLUSION CRITERIA: The review will include qualitative studies examining experiences of nurses caring for people living in shelters following natural hazards and disasters, published in either English or Japanese. Studies published from 2000 to the present will be considered. METHODS: The review will follow the meta-aggregation approach developed by JBI. Published and unpublished studies will be searched using major international databases and other relevant databases for gray literature in either English or Japanese. Two reviewers will independently appraise studies and extract qualitative data using the JBI standardized critical appraisal and extraction instruments. Findings from the review will be categorized according to their similarity in meaning and their categories subjected to a meta-synthesis to produce a single comprehensive set of synthesized findings. The final synthesized findings will be graded according to the ConQual approach.

Effect of remifentanil on intraoperative fluid balance: a retrospective statistical examination of factors contributing to fluid balance.

BACKGROUND: Postoperative fluid retention is a factor that causes delay in recovery and unexpected adverse events. It is important to prevent intraoperative fluid retention, which is putatively caused by intraoperative release of stress hormones, such as ADH (anti-diuretic hormone) or others. We hypothesized that intraoperative analgesia may prevent pathological fluid retention. We retrospectively explored the relationship between analgesics and in-out balance in surgical patients from anesthesia records. METHODS: Anesthetic records of 80 patients who had undergone orthognathic surgery were checked in this study. Patients were anesthetized with either TIVA (propofol and remifentanil) or inhalational anesthesia (sevoflurane and remifentanil). During surgery, acetated Ringer's solution was infused for maintenance at a rate of 3-5 ml/kg/h at the discretion of the anesthetist. The perioperative parameters, including the amount of crystalloid and colloid infused, and the amount of urine and bleeding were checked. Furthermore, we checked the amount and administration rate of remifentanil during the surgical procedure. The correlation coefficient between the remifentanil dose and the in-out balance or the urinary output was analyzed using the Pearson correlation coefficient. The contributing factor to fluid retention, including urinary output, was statistically examined by means of multivariate logistic regression analysis. RESULTS: A significant positive correlation was found between remifentanil dose and urinary output. Urinary output less than 0.04 ml/kg/min was suggested to cause positive fluid balance. Although in-out balance approaches zero balance with increase in remifentanil administration rate, no contributing factor for near-zero fluid balance was statistically picked up. The remifentanil administration rate was statistically picked up as the significant factor for higher urinary output (> 0.04 ml/kg/min) (OR, 2,644; 95% CI, 3.2-2.2 × 106) among perioperative parameters. CONCLUSIONS: In conclusion, remifentanil contributes in maintaining the urinary output during general anesthesia. Although further prospective study is needed to confirm this hypothesis, it was suggested that fluid retention could be avoided through suppressing intraoperative stress response by means of appropriate maintenance of remifentanil infusion rate.

Overeating Risk in Overweight Young Women Is Divided into Two Types According to Appetite and Eating Behavior.

Background: The problem of obesity in young women leads to future chronic diseases, effects on reproductive health, and next-generation obesity. Thus, it is necessary to provide effective support for these women's behavioral change. The purpose of this study was to evaluate dietary-related indicators to clarify the appetite and eating behavior problems among young women. Methods: Healthy women 18-39 years of age were enrolled. Interoceptive awareness (IA) was quantified using a heartbeat perception task score. Eating behavior was examined in three ways: Three-Factor Eating Questionnaire (TFEQ), visual analog scales of subjective appetite sensations, and a food consumption test. Results: In all, 15 participants who were overweight and 50 with normal weight were analyzed. The overweight women were clustered into two groups according to the heartbeat perception task score: a low-score group (women with overweight who have low IA [OW-LOW]) and high-score group (women with overweight who have high IA [OW-HIGH]). The OW-LOW group had significantly smaller intermeal changes in hunger score compared with women with normal weight. The disinhibition score on the TFEQ for the OW-HIGH group was significantly higher than the normal-weight women, and the prospective consumption score in the fasting condition was significantly higher in women with normal weight and a high heartbeat perception task score. Conclusions: Overweight young women were characterized into two groups with different appetite and eating behavior, which is connected to the risk of overeating. An appetite characteristic is associated with a high risk of obesity among the normal-weight population. Individualized interventions tailored to the IA levels may help in improving and preventing obesity.

Impact of diabetes mellitus on postoperative outcomes in individuals with non-small-cell lung cancer: A retrospective cohort study.

OBJECTIVES: Studies showing that individuals with non-small cell lung cancer (NSCLC) and diabetes mellitus (DM) have reported poor outcomes after pulmonary resection with varying results. Therefore, we investigated the clinical impact of preoperative DM on postoperative morbidity and survival in individuals with resectable NSCLC. PATIENTS AND METHODS: Data of individuals who underwent pulmonary resection for NSCLC from 2000 to 2015 were extracted from the database of Kyoto University Hospital. The primary endpoint was the incidence of postoperative complications, and secondary endpoints were postoperative length of hospital stay and overall survival. The survival rate was analyzed using the Kaplan-Meier method. RESULTS: A total of 2,219 patients were eligible for the study. The median age of participants was 67 years. Among them, 39.5% were women, and 259 (11.7%) presented with DM. The effect of DM on the incidence of postoperative complications and postoperative length of hospital stay was not significant. Although the 5-year survival rates were similar in both patients with and without DM (80.2% versus 79.4%; p = 0.158), those with DM who had a hemoglobin A1c level ≥ 8.0% had the worst survival. CONCLUSIONS: In individuals with resectable NSCLC, preoperative DM does not influence the acute phase postoperative recovery. However, poorly controlled preoperative DM could lead to low postoperative survival rates.

Sex-related differences in frailty factors in older persons with type 2 diabetes: a cross-sectional study.

BACKGROUND: This cross-sectional study aimed to describe sex-related differences in diabetes-specific factors underlying the development of frailty in older persons with type 2 diabetes. METHODS: Older persons aged 60-80 years were sequentially enrolled. Frailty and sarcopenia were evaluated using the validated Kihon checklist (KCL) and Asian Working Group for Sarcopenia algorithm, respectively. Physical function and characteristics were measured by trained nurses independently. RESULTS: This study included 213 participants. The mean age, body mass index (BMI), and glycated hemoglobin (HbA1c) level were 70.4 years, 24.3 kg/m2, and 7.4%, respectively. Prevalence of frailty was higher in women. Social and cognitive functions were lower in the prefrailty stage, while physical function was lower in the frailty stage, although there was no decrease in skeletal muscle mass. After adjustment for age, the KCL score was significantly associated with peripheral neuropathy, diet score, and coronary artery disease (CAD); frailty, with CAD and inoccupation; prefrailty, with diet score; and sarcopenia, with living alone in men. Meanwhile, the KCL score was significantly associated with living alone and skeletal muscle percentage; prefrailty, with peripheral neuropathy; and sarcopenia, with diabetes duration, LDL-cholesterol level, diet score, and irregular lifestyle in women. CONCLUSIONS: Sex differences in the risk factors of frailty should be considered when selecting preventive strategies for older persons with type 2 diabetes, early in the prefrailty stage. In particular, it is important to evaluate social participation and diet therapy in men and skeletal muscle mass and psychosocial function in women.
