Introduction: Research on the effects of meteorological parameters on cardiovascular diseases may allow the development of novel prevention strategies.
Aim: The aim of the authors was to examine the correlation between meteorological parameters and the occurrence of acute cardiovascular diseases.
Method: A retrospective analysis was performed in 343 patients diagnosed with acute cardiovascular disease and treated at the Department of Vascular Surgery, Semmelweis University in 2010.
Results: Acute cardiovascular diseases showed a seasonal variation with the highest occurrence in winter months (p = 0.0001). The daily increase of the events (n â„ 3) were associated with front movements days (in 62.5% of cases). A significant correlation was found between the intraday temperature difference (p<0.0001), the intraday atmospheric pressure difference (p = 0.0034), the lowest maximum daily temperature (p<0.0001) and the occurrence of acute cardiovascular diseases. During the days with front movements 64% of the patients were older than 66 years of age. Among risk factors, hypertension showed front sensitivity.
Conclusions: Meteorological parameters are minor risk factors in the occurrence of acute cardiovascular diseases
Gene surgery
Gene therapy became in last decade a new emerging therapeutic era showing promising results against different diseases such as cancer, cardiovascular diseases, diabetes, and neurological disorders. Recently, the genome editing technique for eukaryotic cells called CRISPR-Cas (Clustered Regulatory Interspaced Short Palindromic Repeats) has enriched the field of gene surgery with enhanced applications. In the present review, we summarized the different applications of gene surgery for treating human diseases such as cancer, diabetes, nervous, and cardiovascular diseases, besides the molecular mechanisms involved in these important effects. Several studies support the important therapeutic applications of gene surgery in a large number of health disorders and diseases including ÎČ-thalassemia, cancer, immunodeficiencies, diabetes, and neurological disorders. In diabetes, gene surgery was shown to be effective in type 1 diabetes by triggering different signaling pathways. Furthermore, gene surgery, especially that using CRISPR-Cas possessed important application on diagnosis, screening and treatment of several cancers such as lung, liver, pancreatic and colorectal cancer. Nevertheless, gene surgery still presents some limitations such as the design difficulties and costs regarding ZFNs (Zinc Finger Nucleases) and TALENs (Transcription Activator-Like Effector Nucleases) use, off-target effects, low transfection efficiency, in vivo delivery-safety and ethical issues
Comparing Two Surgical Outcomes: Minithoracotomy or Full Sternotomy in Coronary Artery Bypass Grafting Surgery
Cardiovascular diseases and heart-related conditions can be life-threatening; however, some cardiovascular conditions can be managed with open heart surgery. Coronary artery bypass grafting (CABG) is the most common type of heart surgery performed on adults. There are two different surgical procedures to correct cardiac defects: mini-thoracotomy and full sternotomy. Mini thoracotomy approach has been shown to reduce complications, such as pneumonia, excessive blood loss, and infection in mitral valve repair surgeries. However, little research has been done to compare these two surgical approaches performed for patients undergoing coronary artery bypass grafting (CABG).
Specifically, there is inadequate data to compare these two surgical approaches in relation to length of stay and duration of ventilator use. The purpose of this study was to compare the surgical outcomes of mini-thoracotomy and full sternotomy in patients undergoing CABG surgeries. A retrospective chart review was conducted from an archival data (2010 to 2016) in patients undergoing CABG surgeries with either a mini-thoracotomy or full sternotomy approach. Included were patients with coronary artery blockages who required CABG surgeries. A one-way ANOVA and independent sample t-test were used for statistical analysis.
Results showed that, there was no significant difference in days of hospitalization in those receiving mini-thoracotomy (M= 10.75, SD=10.25) as compared to those who receiving full- sternotomy (M=11.91, SD= 10.03), F (1,537) = 1.17, p = .23.There was no significant difference in number of hours of ventilation time for mini thoracotomy (M= 13.62, SD= 17.58) and full sternotomy (M= 22.33, SD= 95.96), F (1,537) = .90, p=.34.
As the length of hospitalization and duration of ventilation did not differ in both surgical approaches, we can conclude that mini-thoracotomy was very comparable to full-sternotomy in these two areas for patients undergoing coronary artery bypass grafting
Is type 2 diabetes really resolved after laparoscopic sleeve gastrectomy? Glucose variability studied by continuous glucose monitoring
The study was carried out on type 2 diabetic obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Patients underwent regular glycemic controls throughout 3 years and all patients were defined cured from diabetes according to conventional criteria defined as normalization of fasting glucose levels and glycated hemoglobin in absence of antidiabetic therapy. After 3 years of follow-up, Continuous Glucose Monitoring (CGM) was performed in each patient to better clarify the remission of diabetes. In this study, we found that the diabetes resolution after LSG occurred in 40% of patients; in the other 60%, even if they showed a normal fasting glycemia and A1c, patients spent a lot of time in hyperglycemia. During the oral glucose tolerance test (OGTT), we found that 2 h postload glucose determinations revealed overt diabetes only in a small group of patients and might be insufficient to exclude the diagnosis of diabetes in the other patients who spent a lot of time in hyperglycemia, even if they showed a normal glycemia (<140 mg/dL) at 120 minutes OGTT. These interesting data could help clinicians to better individualize patients in which diabetes is not resolved and who could need more attention in order to prevent chronic complications of diabetes
Requirements for cabin crew medical examinations and assessments
The aim of the current study is to review current regulations relatively to medical requirements necessary to achieve suitability to fly of the cabin crew. There are three classes of flight crew medical standards and licensing. A first class medical certificate is required for all pilots who perform professional flights or skydiving instructors. A second class medical certificate is required only for persons who do not perform professional flights, skydiving activities or any other professional activity related to aircraft piloting (cabin crew, holders of Light Aircraft Pilotâs Licence - LAPL, remote pilot operators). Finally, a third class medical certificate is required for workers engaged in air traffic control
The prognostic importance of chronic end-stage diseases in geriatric patients admitted to 163 Italian ICUs
BACKGROUND: The number of elderly patients undergoing major surgical interventions and then needing admission to intensive care unit (ICU) grows steadily. We investigated this issue in a cohort of 232,278 patients admitted in five years (2011-2015) to 163 Italian general ICUs. METHODS: Surgical patients older than 75 registered in the GiViTI MargheritaPROSAFE project were analyzed. The impact on hospital mortality of important chronic conditions (severe COPD, NYHA class IV, dementia, end-stage renal disease, cirrhosis with portal hypertension) was investigated with two prognostic models developed yearly on patients staying in the ICU less or more than 24 hours. RESULTS: 44,551 elderly patients (19.2%) underwent emergency (47.3%) or elective surgery (52.7%). At least one severe comorbidity was present in 14.6% of them, yielding a higher hospital mortality (32.4%, vs. 21.1% without severe comorbidity). In the models for patients staying in the ICU 24 hours or more, cirrhosis, NYHA class IV, and severe COPD were constant independent predictors of death (adjusted odds ratios [ORs] range 1.67-1.97, 1.54-1.91, and 1.34-1.50, respectively), while dementia was statistically significant in four out of five models (adjusted ORs 1.23-1.28). End-stage renal disease, instead, never resulted to be an independent prognostic factor. For patients staying in the ICU less than 24 hours, chronic comorbidities were only occasionally independent predictors of death. CONCLUSIONS: Our study confirms that elderly surgical patients represent a relevant part of all ICUs admissions. About one of seven bear at least one severe chronic comorbidity, that, excluding end-stage renal disease, are all strong independent predictors of hospital death
Factors Associated With Retinal Vessel Diameters in an Elderly Population: the Thessaloniki Eye Study
Purpose: To identify the factors associated with retinal vessel diameters in the population of the Thessaloniki Eye Study.
Methods: Cross-sectional population-based study (age â„ 60 years). Subjects with glaucoma, late age-related macular degeneration, and diabetic retinopathy were excluded from the analyses. Retinal vessel diameters were measured using the IVAN software, and measurements were summarized to central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), and arteriole to venule ratio (AVR).
Results: The analysis included 1614 subjects. The hypertensive group showed lower values of CRAE (P = 0.033) and AVR (P = 0.0351) compared to the normal blood pressure (BP) group. On the contrary, the group having normal BP under antihypertensive treatment did not have different values compared to the normal BP group. Diastolic BP (per mm Hg) was negatively associated with CRAE (P < 0.0001) and AVR (P < 0.0001), while systolic BP (per mm Hg) was positively associated with CRAE (P = 0.001) and AVR (P = 0.0096). Other factors significantly associated included age, sex, alcohol, smoking, cardiovascular disease history, ophthalmic medication, weight, and IOP; differences were observed in a stratified analysis based on BP medication use.
Conclusions: Our study confirms previous reports about the association of age and BP with vessel diameters. The negative correlation between BP and CRAE seems to be guided by the effect of diastolic BP as higher systolic BP is independently associated with higher values of CRAE. The association of BP status with retinal vessel diameters is determined by diastolic BP status in our population. Multiple other factors are also independently associated with retinal vessel diameters
Health Related Quality of Life in Coronary Patients.
The increase observed in the survival of patients with ischemic cardiopathy, together with
the effect of the disease on the social, professional, and family life of those suffering from it,
have led researchers to consider that the traditional ways of measuring morbidity and
mortality are not adequate for assessing the potential benefits of health care interventions.
For this reason, there is common agreement on the need to use an indicator of subjective
assessment of health, and of health related quality of life (HRQL), as a complementary
criterion for monitoring the results of medical interventions in these patients.
The term "quality of life" (QoL) or health related quality of life (HRQL) came into use during
the 1970s as a multidimensional concept reflecting the overall subjective condition of the
physical and mental welfare of the individual, which is a consequence not only of the
disease but also of the family and social conditions forming the patientâs environment.
The assessment of these patientsâ HRQL has been tackled by several authors using both
disease-specific and generic instruments such as the Nottingham Health Profile, the Sickness
Impact Profile, the SF-36 or the SF-12 health questionnaire. Both types of instrument have
advantages and disadvantages, and they may provide additional information since they
quantify the patientâs overall health.
Using different multidimensional measures, poorer HRQL has been observed in patients
with Acute Myocardial Infarction (AMI) and angina pectoris than in other populations, and
these differences have been related to low social class, female sex, the presence of mental
disorders and the severity of the clinical condition.
Measuring changes in the HRQL of coronary patients is also important as a way of assessing
interventions and predicting needs for social care, because it has been shown that the focus
of attention in the immediate period following a cardiac attack is generally the physical
functioning, but following discharge from hospital and in the longer term, general health,
vitality, social and emotional functions could be at least as important.
In this chapter, we aim to provide an overview of the concept of HRQL and the usefulness
of this measure from the perspective of a coronary patient. Likewise, we intend to review
the main instruments used to assess HRQL and we analyse the factors that have been seen
to affect the quality of life of these patients
Timing of bariatric surgery in people with obesity and diabetes
The use of bariatric surgery in the clinical management of type 2 diabetes in severely obese subjects has been included in the clinical practice recommendations released by the most influential diabetologic associations. However, the timing during the diabetic course in which this use may have the better benefit/risk ratio remains debated. Is it better to use surgery very early in the course of the disease in order to anticipate clinical deterioration, or we should favour a delayed approach in which we reserve the more risky surgery only to patients not adequately controlled with the maximal pharmacologic strategy? In this paper, past and recent evidences about the role of bariatric surgery in the different stages of the clinical course of type 2 diabetes have been revised, starting from pre-diabetes and ending to long-standing diabetic state with established or end-stage macro- and micro-vascular complications. Available evidences strongly advocate in favor of the application of bariatric surgery in the early phase of this course, possibly in the pre-diabetic or in very early diabetic stages. To reserve surgery to more advanced and complicated stages of the disease seems to confer less benefits for the clinical course of diabetes and exposes these more frail patients to the possible side effects of a rapid weight loss
