Redefying the therapeutic strategies against cardiorenal morbidity and mortality: Patient phenotypes

Chronic kidney disease(CKD) patients face an unacceptably high morbidity and mortality, mainly from cardiovascular diseases. Diabetes mellitus, arterial hypertension and dyslipidemia are highly prevalent in CKD patients. Established therapeutic protocols for the treatment of diabetes mellitus, arterial hypertension,and dyslipidemia are not as effective in CKD patients as in the general population. The role of non-traditional risk factors(RF) has gained interest in the last decades. These entail ...     

Overview of Chios Mastic Gum (Pistacia lentiscus) Effects on Human Health

Despite the remarkable development of the medical industry in the current era, herbal products with therapeutic potentials arise as attractive alternative treatments. Consequently, Chios mastiha, a natural, aromatic resin obtained from the trunk and brunches of the mastic tree, has recently gained increasing scientific interest due to its multiple beneficial actions. Chios mastiha is being exclusively produced on the southern part of Chios, a Greek island situated in the northern Aegean Sea, and its therapeutic properties have been known since Greek antiquity. There is now substantial evidence to suggest that mastiha demonstrates a plethora of favorable effects, mainly attributed to the anti-inflammatory and anti-oxidative properties of its components. The main use of mastiha nowadays, however, is for the production of natural chewing gum, although an approval by the European Medicines Agency for mild dyspeptic disorders and for inflammations of the skin has been given. The aim of this article is to summarize the most important data about the therapeutic actions of Chios mastiha and discuss future fields for its medical application.     

Pancreatic Cancer Prognosis,Malnutrition Risk,and Quality of Life: A Cross-Sectional Study

The present cross-sectional prospective study (from January 2017 until December 2020) aimed to evaluate the interrelation between nutritional parameters at the initial evaluation with the changes in QOL indicators and the Progression-Free Survival and Overall Survival in 97 patients with pancreatic cancer. Dietary and nutritional risk assessments, and an evaluation of Frailty and Functional Status were performed. Health-related Quality of Life was evaluated with the EORTC QLQ-C30 questionnaire. Nutritional risk, as evaluated by MNA-SF score, was negatively associated with age (p = 0.003) and positively associated with dynamometry (p = 0.001). In addition, there was a statistically significant difference in the financial difficulties (p = 0.049). OS and PFS were found to decrease in patients who reported having increased fatigue (OS p = 0.007 and PFS p = 0.044). Moreover, higher prevalence of constipation resulted in lower OS and PFS (OS p < 0.001 and PFS p < 0.001) and increased reporting of gastrointestinal problems during the 3 months was connected with lower survival (OS p = 0.017). According to the analysis, our patients were found to have lower OS and PFS, stressing out the necessity to provide early identification and management to symptoms of the disease that could compromise nutritional status. The provision of nutritional advice and guidance is of major importance for patients.     

Do no more harm: The psychological stress of the medical examination for alleged child sexual abuse

Aim:   Currently, there is some controversy that the medical examination following allegations of child sexual abuse may further traumatise the child. Access for children to appropriate care may be hindered if decisions about referral are influenced by personal beliefs, rather than by recognition of the potential health and psychological benefits of the assessment. We aimed to study the expectations and emotional responses of children and their parents to the medical examination.
Methods:   We conducted a prospective quantitative and qualitative study at the Children's Hospital at Westmead. Participants completed questionnaires pre-examination and post-examination, including Children's Anxiety and Pain Scales. Clinicians recorded a Genital Examination Distress Scale and a questionnaire about potentially prognostic variables.
Results:   Parents found the medical examination significantly less stressful than they had anticipated. They highlighted the importance of being involved in the process, the child's reaction, staff attitudes and the doctor's explanations. Although most parents expected that the medical would be stressful for their child, this did not correlate with the children's reports of feeling scared beforehand. Increased parental and child distress were significantly associated with the child being 12 years or older. The type of abuse was not significantly linked to any of the parent or child self-reports.
Conclusion:   Our findings indicate that the medical examination is not as stressful as expected and support the recommendation that timely medical assessment by appropriately trained professionals should be offered for all children following allegations of sexual abuse.     

Headache patients in the emergency department of a Greek tertiary care hospital

The aim of this study was to record the demographic and epidemiological data on adult patients with headache who attend the emergency department (ED) and the diagnoses that made by the neurologists in the ED of a tertiary care hospital in metropolitan Thessaloniki (Greece). In an open prospective study, demographic and epidemiological data were collected on all patients who reported headache (as chief complaint or not) and presented to the ED of Papageorgiou Hospital between August 2007 and July 2008. Headache patients accounted for 1.3% of all ED patients and for 15.5% of patients primarily referred to the ED neurologist. Tension type headache was the most frequent diagnosis, followed by secondary headaches and migraine. The large number of patients without final ED diagnosis and ward admission for further evaluation sheds a light on the immense workload of Greek ED physicians. Furthermore, we found evidence for the misuse of Emergency Medical Services by chronic headache patients. These findings indicate shortcomings in the pre-hospital (primary care) management of headache patients in the Greek National Health System to an extent unreported so far.     

The sympathoadrenal system mediates the blood pressure and cardiac effects of human coagulation factor XII-related "new pressor protein"

OBJECTIVE: To investigate the major cardiovascular effects of human plasma "new pressor protein" (NPP) and how the adrenal medulla contributes to these effects. METHODS: NPP was injected into bioassay rats intravenously, and the effects on blood pressure and cardiac function were investigated. Acute adrenal medullectomy (2MDX), alpha- and beta-adrenergic blockade and plasma catecholamine levels were also used to evaluate the role of the sympathoadrenal system in mediating the NPP effects. RESULTS: NPP significantly raised systolic blood pressure (SBP) and mean arterial pressure but not diastolic blood pressure (DBP), with no significant change in total peripheral resistance. Heart rate, cardiac output and stroke volume rose by 16%, 53% and 36%, respectively. Plasma catecholamines increased massively, notably adrenaline, raising the adrenaline to noradrenaline ratio from about 4:1 to 18:1. 2MDX attenuated the increments of SBP and heart rate by more than 90% and more than 70%, respectively, implicating the adrenal medulla. Beta-adrenergic blockade (propranolol) potentiated the NPP-induced increase of SBP and DBP, but not that of heart rate. Combined alpha- and beta-adrenergic blockade (phentolamine and propranolol) blocked the rise in SBP, DBP and heart rate. CONCLUSIONS: NPP's hypertensive action is attributable mainly to increases in systolic blood pressure, heart rate and cardiac output (an increase in heart rate and stroke volume) with massive release of adrenal medullary catecholamines. Such effects suggest a novel axis between coagulation factor XII and the sympathoadrenal system, the cardiovascular effects of which are controlled by combined alpha- and beta-adrenergic blockade, but not by angiotensin-converting enzyme inhibition. Clinical relevance depends on whether NPP is formed in vivo in thrombotic states.     

Posterior cerebral artery occlusion associated with Mycoplasma pneumoniae infection

Cerebral infarction is a rare complication of Mycoplasma pneumoniae infection. In all cases previously reported in the literature, vascular occlusion occurred in the anterior brain circulation, either the internal carotid or the middle cerebral artery. We report a case of a child with posterior cerebral artery occlusion and resultant hemiparesis associated with M. pneumoniae infection.
