Lipid profile and atherogenic indices in patients with stable chronic obstructive pulmonary disease

Background and aimsLimited number of studies investigated lipid profile in chronic obstructive pulmonary disease (COPD) with inconsistent results. This study aimed to investigate lipid parameters in sera of patients with stable COPD and their associations with disease severity, smoking, comorbidities and therapy.Methods and resultsThe study included 137 COPD patients and 95 controls. Triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were assessed. Non-HDL-C (NHC), atherogenic coefficient (AC), TG/HDL-C, atherogenic index of plasma (AIP), Castelli's risk index I and II (CRI-I, CRI-II), and monocyte to HDL ratio (MHR) were calculated.HDL-C and MHR were increased, while other lipid parameters and indices were decreased in COPD patients compared to healthy individuals. Smoking did not influence lipid parameters. However, lipid profile was altered only in more severe disease stages. AC, CRI-I and CRI-II showed positive association with lung function parameters in COPD patients, and negative with COPD multicomponent indices (ADO, BODCAT, BODEx, CODEx and DOSE). Combined model that included CRI-II, C-reactive protein, fibrinogen and white blood cells showed great diagnostic performances, and correctly classified 72% of study participants with an AUC of 0.800 (0.742–0.849), P < 0.001. Bronchodilator monotherapy and statins have opposite impact on TC, LDL-C and NHC, while TG, TG/HDL-C and AIP were increased in COPD patients with cardiovascular diseases.ConclusionLipid disbalance is present in COPD, and it seems to occur later as the disease progresses. Further studies are needed to illuminate the underlying mechanism of dyslipidaemia.     

Age-specific associations between underlying health conditions and hospitalisation,death and in-hospital death among confirmed COVID-19 cases: a multi-country study based on surveillance data,June to December 2020

BackgroundUnderlying conditions are risk factors for severe COVID-19 outcomes but evidence is limited about how risks differ with age.AimWe sought to estimate age-specific associations between underlying conditions and hospitalisation, death and in-hospital death among COVID-19 cases.MethodsWe analysed case-based COVID-19 data submitted to The European Surveillance System between 2 June and 13 December 2020 by nine European countries. Eleven underlying conditions among cases with only one condition and the number of underlying conditions among multimorbid cases were used as exposures. Adjusted odds ratios (aOR) were estimated using 39 different age-adjusted and age-interaction multivariable logistic regression models, with marginal means from the latter used to estimate probabilities of severe outcome for each condition–age group combination.ResultsCancer, cardiac disorder, diabetes, immunodeficiency, kidney, liver and lung disease, neurological disorders and obesity were associated with elevated risk (aOR: 1.5–5.6) of hospitalisation and death, after controlling for age, sex, reporting period and country. As age increased, age-specific aOR were lower and predicted probabilities higher. However, for some conditions, predicted probabilities were at least as high in younger individuals with the condition as in older cases without it. In multimorbid patients, the aOR for severe disease increased with number of conditions for all outcomes and in all age groups.ConclusionWhile supporting age-based vaccine roll-out, our findings could inform a more nuanced, age- and condition-specific approach to vaccine prioritisation. This is relevant as countries consider vaccination of younger people, boosters and dosing intervals in response to vaccine escape variants.     

Pelvic Floor Muscle Problems Mediate Sexual Problems in Young Adult Rape Victims

IntroductionPrior studies have addressed sexual abuse and sexual function in adult women. No studies have focused on the effect of adolescence rape on sexual functioning.AimTo investigate the effect of rape on sexual problems and on pelvic floor problems, as well as the mediating role of pelvic floor problems on sexual problems, in a homogenous group of victims of adolescence rape without a history of childhood sexual, physical, and/or emotional abuse.Main Outcome MeasuresSexual functioning and pelvic floor functioning were assessed using self‐report questionnaires.MethodsIn this cross‐sectional study, a group of 89 young women aged 18–25 years who were victimized by rape in adolescence was compared with a group of 114 nonvictimized controls. The rape victims were treated for posttraumatic stress disorder (PTSD) 3 years prior to participation in the study.ResultsThree years posttreatment, rape victims were 2.4 times more likely to have a sexual dysfunction (lubrication problems and pain) and 2.7 times more likely to have pelvic floor dysfunction (symptoms of provoked vulvodynia, general stress, lower urinary tract, and irritable bowel syndrome) than nonvictimized controls. The relationship between rape and sexual problems was partially mediated by the presence of pelvic floor problems. Rape victims and controls did not differ with regard to sexual activities.ConclusionsRape victims suffer significantly more from sexual dysfunction and pelvic floor dysfunction when compared with nontraumatized controls, despite the provision of treatment for PTSD. Possibly, physical manifestations of PTSD have been left unaddressed in treatment. Future treatment protocols should consider incorporating (physical or psychological) treatment strategies for sexual dysfunction and/or pelvic floor dysfunction into trauma exposure treatments.

Cardiopulmonary exercise testing in the evaluation of functional capacity after treatment of lymphomas in adults

The present study assessed several parameters of cardiopulmonary function in patients, after treatment for aggressive non-Hodgkin's lymphoma and Hodgkin's disease, to determine the influence of these parameters on patient's performance status. One hundred and six patients (66 male and 40 female) aged 40 +/- 15 years were examined 1-2 years (median 14 months) after anticancer treatment. The patients were examined by means of rest and dynamic stress echocardiography and cardiopulmonary exercise. The rest and post-exercise ejection fraction (EF), Doppler parameters of left ventricular diastolic function and peak oxygen consumption (pVO2) were used as parameters of cardiopulmonary performance. The cumulative dose (CD) of doxorubicin (DOX) given was 240 +/- 70 (240 mg/m2). Thirty-seven percent of patients received mediastinal irradiation in accordance with the used treatment protocol. Sixty-four patients (60%) experienced fatigue after the treatment. Three patients (3%) demonstrated an decreased EF <50%, 34 (32%) demonstrated impaired diastolic function, 14 (13%) demonstrated decreased pVO2<20 ml/kg/min and 15 (14%) demonstrated a value of pVO2 below the reference value, respectively. None of the patients exhibited clinical signs of heart failure. Apart from three patients with a rest EF<50%, all the other patients responded to stress echocardiography with an increment of EF > 5%. The parameter pVO2 significantly correlated with stress EF (0.58, P < 0.0002). A significant relationship was found with all parameters of diastolic function: to index E/A of diastolic filling (r = 0.67, P < 0.0001), isovolumic relaxation time (r = -0.56, P < 0.0009) and to deceleration time (r = -0.54, P < 0.009), respectively. A negative relationship was found with age (r = -0.74, P < 0.0001), CD of DOX (r = -0.53, P < 0.003) and radiotherapy-involving mediastinum (r = - 0.44, P < 0.04), respectively. Using multivariate analysis, a significant relationship was found between pVO2 and parameters of diastolic filling, age, female sex and CD of DOX, respectively (r = 0.58, P < 0.0001). Diastolic dysfunction was correlated with age, CD of DOX and radiotherapy-involving mediastinum, respectively (r = 0.51, P < 0.01). The results show that diastolic dysfunction was the most affected parameter of cardiopulmonary function in cancer survivors. This parameter negatively influenced cardiopulmonary performance and was significantly correlated with the cumulative dose of doxorubicin given and radiotherapy on mediastinum. Despite a high number of patients experiencing fatigue, the study demonstrates that only a relatively small number of patients show a depressed pVO2 on a cardiopulmonary stress test and other cardiac abnormalities. The results of the tests support the introduction of regular aerobic exercise for cancer survivors to increase their cardiopulmonary performance and well-being. Hypothetically, aerobic training may also positively influence diastolic function. However, this assumption warrants a prospective follow-up.     

Treatment of Squamous Cell Carcinoma with Interferon

Human natural leukocytic interferon and recombinant HulFN alpha 2c can be used in the therapy of squamous cell carcinoma. The duration of treatment was 3-6 weeks. A single dose was 400,000-5,000,000 units given weekly for 3-6 weeks. Clinically and histologically 19 of 32 patients were cured and tumor cells were not found in the material taken after interferon treatment for the second biopsy. In ten patients tumor size was reduced 25-90%, and in three patients tumor size was not reduced according to clinical findings. With recombinant HulFN alpha 2c therapy given 5 times per week for 4 weeks. Four of ten patients with similar tumors were cured clinically and histologically clinical findings. In five patients tumor size was reduced 25-90%, while in one patient there was no reduction in tumor size. Both types of interferons are effective in the treatment of squamous cell carcinoma. Side reactions were mild.     

Surgical treatment of Wolff-Parkinson-White syndrome

The results of surgical treatment of 365 patients with the WPW syndrome are analysed. They underwent operation at the surgical department of the Kanazawa University Medical School in the period between 1973 and 1989. In 1969 T. Iva suggested an endocardial approach from the direction of the atrium for removal of the additional pathways, which the authors use at present also. The anomalies were congenital in 47 and acquired in 12 patients and were corrected in one stage during removal of the additional pathways. Multiple additional pathways were found in 33 patients. The additional pathways were completely removed in 33 patients. Paroxysms of tachycardia do not occur after the operation in 364 patients among the 365 who were operated on.     

Temperature related mortality and ambulance service interventions during the heat waves of 2003 in Ticino (Switzerland)

Summary. Objectives This study investigates a potential increase in mortality and in the demand for ambulance emergency services among the elderly in particular, in Ticino in the summer of 2003. Methods Mortality rates and emergency ambulance interventions rates were compared with records from the previous years. We considered the whole population, aged 65 and over, as well as 75 and over. Results The 2003 mortality in the population was not signifi cantly different from the previous years. The number of deaths among the elderly showed a small but significant deviation from the expected values during the first heat wave in June 2003, with no significant impact on the seasonal results. The number of ambulance service interventions was larger than during the previous years. Conclusion These results are consistent with findings in other studies. The heat waves (especially in June), were correlated with a higher number of ambulance callouts. In addition to some geographic, climatic, and social factors that had a protective impact, the response of the emergency services is likely to have contributed to a certain reduction in mortality.
