Sex-related differences in the impact of nutritional status on in-hospital mortality in heart failure: a retrospective cohort study.

AIMS: A nutritional status is related to the length of hospitalization and in-hospital mortality of patients with heart failure (HF). The aim of this study is to assess the prognostic impact of nutritional status and body mass index (BMI) on in-hospital mortality among patients with HF relative to their sex. METHODS AND RESULTS: We conducted a retrospective study and analysis of 809 medical records of patients admitted to the Institute of Heart Disease of the University Clinical Hospital in Wroclaw (Poland). Women were statistically significantly older than men (74.67 ± 11.15 vs. 66.76 ± 17.78; P < 0.001). In unadjusted model, significant predictors of the odds of in-hospital mortality for men were underweight (OR = 14.81, P = 0.001) and the risk of malnutrition (OR = 8.979, P < 0.001). In the case of women, none of the traits analysed was significant. In age-adjusted model, significant independent predictors of the odds of in-hospital mortality in the case of men were BMI < 18.5 (OR = 15.423, P = 0.001) and risk of malnutrition (OR = 5.557, P = 0.002). In the case of women, none of the nutritional status traits analysed were significant. In multivariable-adjusted model in men, significant independent predictors of the odds of in-hospital mortality were BMI < 18.5 (OR = 15.978, P = 0.007) compared with having normal body weight and the risk of malnutrition (OR = 4.686, P = 0.015). In the case of women, none of the nutritional status traits analysed were significant. CONCLUSION: Both underweight and the risk of malnutrition are direct predictors of the odds of in-hospital mortality in men, but not in women. The study did not find a relationship between nutritional status and in-hospital mortality in women.

Sex-related differences in the impact of nutritional status on length of hospital stay in atrial fibrillation: a retrospective cohort study.

Background: Nutritional status is related to the length of hospitalization of patients with atrial fibrillation (AF). The aim of this study is to assess the prognostic impact of nutritional status and body mass index on length of hospital stay (LOHS) among patients with AF relative to their sex. Methods: A retrospective analysis of the medical records of 1,342 patients admitted urgently with a diagnosis of AF (ICD10: I48) to the Cardiology Department (University Hospital in Wroclaw, Poland) between January 2017 and June 2021. Results: In the study group, women were significantly older than men (72.94 ± 9.56 vs. 65.11 ± 12.68, p < 0.001). In an unadjusted linear regression model, malnutrition risk was a significant independent predictor of prolonged hospitalization in men (B = 1.95, p = 0.003) but not in women. In the age-adjusted linear regression model, malnutrition risk was a significant independent predictor of prolonged hospitalization in men (B = 1.843, p = 0.005) but not in women. In the model adjusted for age and comorbidities, malnutrition risk was a significant independent predictor of prolonged hospitalization in men only (B = 1.285, p = 0.043). In none of the models was BMI score a predictor of LOHS in either sex. Conclusion: The risk of malnutrition directly predicts the length of hospital stays in men but not women. The study did not find a relationship between body mass index and length of hospital stay in both women and men.

Sex-related differences in the impact of nutritional status on in-hospital mortality in acute coronary syndrome: A retrospective cohort study.

BACKGROUND AND AIMS: In patients with some cardiovascular disease conditions the result of Nutritional Risk Screening 2002 (NRS-2002) and body mass index (BMI) is related to the in-hospital mortality. The aim of this study was to assess the prognostic impact of BMI and NRS 2002 on in-hospital mortality among patients with acute myocardial infarction (AMI) in relation to sex. METHODS AND RESULTS: The study was based on a retrospective analysis of 945 medical records of AMI patients admitted to the Cardiology Department between 2017 and 2019. Patients with a score NRS2002 ≥ 3 are considered to be nutritionally at risk. The WHO BMI criteria were used. The endpoint was in-hospital mortality. Logistic regression was used to analyse the impact of quantitative variables on dichotomous outcome. Odds ratios (OR) with 95% confidence intervals were reported. Female patients were significantly older than male patients (73.24 ± 11.81 vs 67 ± 11.81). In an unadjusted model, the risk of malnutrition was a significant predictor of the odds of in-hospital mortality only in female patients (OR = 7.51, p = 0.001). In a multivariate model adjusted by all variables, heart failure (HF) (OR = 8.408, p = 0.003) and the risk of malnutrition (OR = 6.555, p = 0.007) were independent predictors of the odds of in-hospital mortality in female patients. The only significant independent predictor of the odds of in-hospital mortality in male patients was HF (OR = 3.789 p = 0.006). CONCLUSIONS: Only in the case of female patients with AMI, the risk of malnutrition was independently associated with the odds of in-hospital mortality. There was no effect of BMI on in-hospital mortality in both sexes.

The Association between Nutritional Status and Length of Hospital Stay among Patients with Hypertension.

BACKGROUND: Nutritional status is related to the prognosis and length of hospital stay (LOS) of patients with hypertension (HT). This study aimed to assess how nutritional status and body mass index (BMI) affect LOS for patients with hypertension. METHOD: We performed a retrospective analysis of 586 medical records of patients who had been admitted to the Institute of Heart Diseases of the University Clinical Hospital in Wroclaw, Poland. RESULTS: A total of 586 individuals were included in the analysis. Individuals who were at a nutritional risk represented less than 2% of the study population, but more than 60% were overweight or obese. The mean BMI was 28.4 kg/m2 (SD: 5.16). LOS averaged 3.53 days (SD = 2.78). In the case of obese individuals, hospitalisation lasted for 3.4 ± 2.43 days, which was significantly longer than for patients of normal weight. For underweight patients, hospitalisation lasted for 5.14 ± 2.27 days, which was also significantly longer than for those in other BMI categories (p = 0.017). The independent predictors of shorter hospitalisations involved higher LDL concentration (parameter of regression: -0.015) and HDL concentration (parameter of regression: -0.04). CONCLUSIONS: The study revealed that with regard to the nutritional status of hypertensive patients, being either underweight or obese was associated with longer LOS. Additional factors that related to prolonged LOS were lower LDL and HDL levels and higher CRP concentrations.

Relationship between nutritional status and length of hospital stay among patients with atrial fibrillation - a result of the nutritional status heart study.

Background: Nutritional status is related to the prognosis and length of hospital stay (LOHS) of patients with atrial fibrillation (AF). This study aimed to assess how nutritional status affects LOHS for patients with AF. Methods: We performed retrospective analysis of the medical records of 1,813 patients admitted urgently with a diagnosis of AF to the Institute of Heart Diseases of the University Clinical Hospital in Wroclaw, Poland. Results: In total, 1,813 patients were included in the analysis. The average LOHS in the entire group was 3.53 ± 3.41 days. The mean BMI was 28.7 kg/m2 (SD: 5.02). Patients who were hospitalized longer were statistically more likely to have a Nutritional Risk Score (NRS) ≥3 (p = 0.028). A higher percentage of longer hospitalized patients with LDL levels below 70 mg/dl (p < 0.001) and those with HDL ≥40 mg/dl (p < 0.001) were observed. Study participants with NRS ≥3 were an older group (M = 76.3 years), with longer mean LOHS (M = 4.44 days). The predictors of LOHS in the univariate model were age (OR = 1.04), LDL (OR = 0.99), HDL (OR = 0.98), TC (OR = 0.996), CRP (OR = 1, 02, p < 0.001), lymphocytes (OR = 0.97, p = 0.008) and in the multivariate model were age, LDL (mg/dl), HDL (mg/dl), Na, and K. Conclusion: For nutritional status, factors indicating the risk of prolonged hospitalization in patients with AF are malnutrition, lower serum LDL, HDL, potassium, and sodium levels identified at the time of admission to the cardiology department. Assessment of nutritional status in patients with AF is important both in the context of evaluating obesity and malnutrition status, as both conditions can alter the prognosis of patients. Further studies are needed to determine the exact impact of the above on the risk of prolonged hospitalization.

The Association between Nutritional Status and In-Hospital Mortality among Patients with Heart Failure-A Result of the Retrospective Nutritional Status Heart Study 2 (NSHS2).

BACKGROUND: A nutritional status is related to the prognosis and length of hospitalisation of patients with heart failure (HF). This study aims to assess the effect of nutritional status on in-hospital mortality in patients with heart failure. METHODS: We conducted a retrospective study and analysis of medical records of 1056 patients admitted to the cardiology department of the University Clinical Hospital in Wroclaw (Poland). RESULTS: A total of 1056 individuals were included in the analysis. A total of 5.5% of patients died during an in-hospital stay. It was found that in the sample group, 25% of patients who died had a BMI (body mass index) within the normal range, 6% were underweight, 47% were overweight, and 22% were obese. Our results show that non-survivors have a significantly higher nutrition risk screening (NRS) ≥3 (21% vs. 3%; p < 0.001); NYHA (New York Heart Association) grade 4 (70% vs. 24%; p < 0.001). The risk of death was lower in obese patients (HR = 0.51; p = 0.028) and those with LDL (low-density lipoprotein) levels from 116 to <190 mg/dL (HR = 0.10; p = 0.009, compared to those with LDL <55 mg/dL). The risk of death was higher in those with NRS (nutritional risk score) score ≥3 (HR = 2.31; p = 0.014), HFmrEF fraction (HR = 4.69; p < 0.001), and LDL levels > 190 mg/dL (HR = 3.20; p = 0.038). CONCLUSION: The malnutrition status correlates with an increased risk of death during hospitalisation. Higher TC (total cholesterol) level were related to a lower risk of death, which may indicate the "lipid paradox". Higher BMI results were related to a lower risk of death, which may indicate the "obesity paradox".

The Association between Nutritional Status and In-Hospital Mortality among Patients with Acute Coronary Syndrome-A Result of the Retrospective Nutritional Status Heart Study (NSHS).

BACKGROUND: Nutritional status is related to the prognosis and the length of hospitalization of individuals with myocardial infarction. This study aimed to assess the effects of nutritional status on in-hospital mortality in patients with acute coronary syndrome. METHODS: We performed a retrospective study of 1623 medical records of patients admitted to the cardiology department of the University Clinical Hospital in Wroclaw (Poland) between 2017 and 2019. RESULTS: It was found that, of those who died in the sample, 50% had a BMI within the normal range, 29% were in the overweight range and 18% were in the obese range. Patients who died had significantly more frequent occurrences of the following: Nutrition Risk Screening (NRS) ≥ 3 (20% vs. 6%; p < 0.001); heart failure (53% vs. 25%; p < 0.001); or a history of stroke (22% vs. 9%; p < 0.001), arterial hypertension (66% vs. 19%; p < 0001) or diabetes (41% vs. 19%; p < 0.001). Statistically significant differences were found when considering the type of infarction, diabetes or people with low-density lipoprotein greater than or equal to 70 mg/dL. CONCLUSIONS: This study shows that malnutrition correlates with an increased risk of death during hospitalization.

Nutrition Trends in Patients Over the Long Term After Kidney Transplantation.

OBJECTIVES: Nutritional behaviors may exert important influence on morbidity and graft function in patients after kidney transplantation (KT). Nutritional status is closely related to potential risk factors of developing posttransplant complications, including diabetes mellitus, weight gain, and negative effects on immunosuppressive therapy. The aim of this study was to assess the dietary intake in patients after KT. DESIGN AND METHODS: Nutritional intake of 154 (61 women and 93 men) patients was assessed based on a questionnaire regarding food intake (proteins, fats, carbohydrates, cholesterol, sugar, phosphorus, calorific value) within 3 working days preceding the routine outpatient posttransplant visit. Patient medical history, concomitant medications, and estimated glomerular filtration rate (eGFR) was obtained from medical charts. RESULTS: The mean age (years) ± SD of patients was 51.9 ± 14.1. The patients were evaluated 94 ± 67 months after KT, with a median eGFR of 53 (range, 41.2-64.1) mL/min/1.73 m2. Sixty-two percent of patients had increased body mass index values. The mean total energy intake was 2159.4 ± 551.9 kcal/day. The patients reported elevated salt (8.5 ± 2.4 g per day) and fat intake (99.4 ± 3.2 g per day) including 57% saturated fatty acids. The patients consumed products containing high amounts of sugars (108.2 ± 107.0 g per day), carbohydrates (238.3 ± 64.3 g per day), and cholesterol (303.6 ± 11.1 mg per day). The diet among kidney recipients consisted predominantly of fats, meat, cured meat, and sweets. CONCLUSIONS: The nutritional behaviors of patients after KT are in most cases poor. Improvement of eating habits in these patients seems to be a simple method to preserve kidney function over the long term.

[The importance of diet in the prevention of adverse reactions to vitamin K-dependent anticoagulants]. / The importance of diet in the prevention of adverse reactions to vitamin K-dependent anticoagulants.

Due to the increasing number of patients suffering from cardiovascular diseases, the number of patients started on anticoagulants is also rising. Diet is a modifiable factor of effective treatment. It is of particular importance due to the strong correlation of anticoagulants with vitamin K, other diet components and drug-food interactions in long-term treatment. Chronic treatment with anticoagulants may precipitate a number of adverse reactions, and following an appropriate diet may minimise the side effects of drugs that alter blood coagulation. There is a relationship between diet rich in vitamin K and oral VKAs. Maintaining a constant concentration of vitamin K in everyday diet allows to decrease complications resulting from chronic intake of hydroxycoumarin derivatives. Nutritional education of patients on longterm treatment with VKAs may help to decrease adverse reactions. Collaboration between the patient and the dietician and between the dietician and the doctor may positively affect the maintenance of a stable diet necessary in patients undergoing long-term anticoagulant treatment.

[Effect of treatment with diet on reducing levels of sex hormones in perimenopausal women with overweight and obesity]. / Wplyw leczenia dieta redukcyjna na stezenie hormonów plciowych u kobiet w okresie okolomenopauzalnym z nadwaga i otyloscia.

UNLABELLED: Nowadays, fight against obesity is a big challenge for the developed countries. Perimenopausal women are especially prone to becoming overweight and obese. This is due to changes in hormone levels and alterations in the sex hormones synthesis pathway. AIM: The aim of this study was to evaluate the levels of sex hormones in overweight and obese women during menopause following the three month period of reducing diet. MATERIALS AND METHODS: The study involved women aged 55±4,75 years. Group I - 33 overweight women (BMI 28,06±1,00 kg/m(2)). Group II - 32 obese women (BMI 34,22±3,79 kg/m(2)). Anthropometric measurements, body composition tested with Bodystat QuadScan 4000 analyzer and levels of sex hormones in the blood was determined before and after the three-months of reducing diet in both groups. Statistical data analysis was performed. RESULTS: After three-months of reducing diet it was noticed that levels of BMI, body fat, FSH, DHEA-S and androstenedione were decreased in a statistically significant manner. A significant increase in estradiol levels after reduction of visceral adipose tissue in both groups, overweight and obese women, was observed. However, only in the group of obese women, a decrease in BMI correlated with a significant increase in estradiol levels. CONCLUSIONS: Application of appropriate reducing diet in perimenopausal overweight and obese women has positive impact on visceral adipose tissue distribution and causes an increase in sex hormones levels. Perimenopausal overweight and obese women should pursue weight reduction to improve their chances of contracting cardiovascular diseases.

[Estimation of small intestinal bacterial overgrowth in patients with constipation and diarrhea irritable bowel syndrome]. / Ocena przerostu flory bakteryjnej w jelicie cienkim u osób z zaparciowa i biegunkowa postacia zespolu jelita nadwrazliwego.

UNLABELLED: Irritable bowel syndrome (IBS) is one of the most common reason for gastroenterology consultations. The diverse in symptomatology of the disease comes from its rich etiopathogenesis. Recently studies talk about infectious etiology of IBS and because of that it is necessary to expand its diagnostics by small intestinal bacterial overgrowth (SIBO) test. The aim of this study was to evaluate the prevalence of small intestinal bacterial overgrowth in patients with constipation (IBS-C) and diarrhea (IBS-D) irritable bowel syndrome with regard to nutrition. MATERIALS AND METHODS: The study involved 46 subjects (33 women and 13 men) in average age of 44 years, which were divided into two groups: diarrhea and constipation IBS. All patients underwent hydrogen breath test studying bacterial overgrowth in the small intestine. In addition, each person had fulfilled a feeding questionnaire. STATISTICAL ANALYSIS: Student's t-test, Pearson test. RESULTS: It has been shown that there is no statistical significances between the prevalence of SIBO in form of diarrheal IBS and constipation IBS and gender. Average value of increments of hydrogen in breath during the test was higher in IBS-C in comparison with IBS-D, which was the highest in the intestine bacterial overgrowth in patients with IBS-C. STATISTICAL ANALYSIS showed that there is no relationship between the type and frequency of consumption of milk, meat, fruit and vegetables, sweets and coffee and the prevalence of SIBO in form of diarrhea and constipation IBS. CONCLUSIONS: The occurrence of constipation or diarrhea irritable bowel syndrome is not related to gender. SIBO is more common in patients with IBS-C than in IBS-D group. There is no relationship between the type of food consumed and the amount of SIBO in people with IBS. Type of food intake do not affect the status of the intestinal flora of people with IBS.

Influence of melatonin on symptoms of irritable bowel syndrome in postmenopausal women.

INTRODUCTION: Melatonin (MEL) exerts beneficial effects on the gut partly by myorelaxative properties upon the smooth muscle. Its secretion decreases with age, particularly in postmenopausal women. This study was aimed at evaluating the effect of MEL on the symptoms of irritable bowel syndrome (IBS) in this group of patients. MATERIAL AND METHODS: The investigations were carried out in 80 postmenopausal women, aged 48-65 years, divided into two equal groups, diagnosed according to Rome Criteria III: i.e. patients with IBS with constipation predominant (IBS-C), and patients with IBS with diarrhoea predominant (IBS-D). The control group (C) included healthy women aged 46-65 years. In all subjects, 6-sulfatoxymelatonin (6-HMS) concentration urine was measured using ELISA assay. Patients in both groups over the course of six months were given melatonin (at a dose of 3 mg fasting and 5 mg at bedtime) or a placebo (double blind trial). Disease activity was evaluated after two, four and six months, using a ten-point scale to assess the main somatic symptoms: visceral pain, abdominal bloating, etc. RESULTS: The amounts of 6-HMS urine excretion (µg/24 h) were: C 11.4 ± 3.0, IBS-C 10.2 ± 3.2, IBS-D 14.0 ± 6.3 (p 〈 0.05). Correlation between values of symptoms score and contrary excretion of 6-HMS: IBS-C r = -0.714, IBS-D r = 0.409. After six months in the IBS-C group, the intensity of visceral pain and abdominal bloating had decreased in 70% of patients (p 〈 0.01) and constipation in 50% of patients (p 〈 0.05). Beneficial changes in the IBS-D group were noted in 45% of patients, but this was not better compared to the placebo. CONCLUSIONS: Melatonin can be used as part of the treatment of IBS, particularly in patients with constipation-predominant IBS.
