Disconnectedness from the here-and-now: a phenomenological perspective as a counteract on the medicalisation of death wishes in elderly people

When elderly people are ideating on manners to end their lives, because they feel life is over and no longer worth living, it is important to understand their lived experiences, thoughts and behaviour in order to appropriately align care, support and policy to the needs of these people. In the literature, the wish to die in elderly people is often understood from a medical, psychopathological paradigm, referred to as cognitive impairment, depressive disorder, pathological bereavement, and suicidality. In this paper, we evaluate this dominant paradigm by considering three serious limitations, namely: (1) the risk of epistemic transformation; (2) the risk of reduction; and (3) the risk of obscuring the social and cultural embeddedness. Drawing on insights from our empirical–phenomenological research on the issue of elderly and the self-chosen death, this paper argues for a phenomenological perspective to counteract the medicalisation of death wishes in elderly people.     

Positron emission tomography in imaging evaluation of staging,restaging, treatment response,and prognosis in prostate cancer

Prostate cancer is a prevalent public health problem worldwide. While imaging has played a major role in this disease, there still remain many challenges and opportunities. Positron emission tomography with various physiologically based radiotracers is fundamentally suited to interrogate this biologically and clinically heterogeneous disease along the course of its natural history. In this article, I review briefly the published evidence for the use of positron emission tomography with 18F-fluorodeoxyglucose, 11C-acetate, and 18F- or 11C-choline in the imaging evaluation of prostate cancer. Although the focus of the article will be on these radiotracers given the accumulated experience with them, but I will also comment on the outlook for the use of other emerging PET radiotracers such as those targeted to the prostate-specific membrane antigen and the amino acid metabolism pathway. It is anticipated that PET will play major role in the evaluation of prostate cancer in the current evidence-based medicine environment. There will also be exciting novel prospects for the use of therapeutic-diagnostic (theransotic) pairs in the management of patients with prostate cancer.     

Factors Driving the HIV Epidemic in Southern Africa

The HIV pandemic has disproportionately impacted sub-Saharan Africa and Southern Africa in particular. The concurrent presence of overlapping epidemic drivers likely underpins how and why the HIV epidemic is so explosive in this region, with implications for understanding approaches to reduce transmission. In this review, we discuss the relative contribution and interaction between epidemic drivers in the Southern African context, including factors both distally and proximally associated with the likelihood and degree of exposure to HIV and factors that increase the probability of transmission when exposure occurs. In particular, we focus on young women as a key population in need of HIV prevention and highlight factors that increase their risk on several levels.     

Perineal Rectosigmoidectomy (Altemeier Procedure) as Treatment of Strangulated Rectal Prolapse

Incarceration of a rectal prolapse is an unusual entity that represents a surgical emergency. Even more rarely, it becomes strangulated, requiring emergency surgery. When surgery becomes inevitable, the choice of procedure varies. A 57-year-old man who presented with strangulated rectal prolapse is described. The patient underwent emergency perineal proctosigmoidectomy, the Altemeier operation, combined with diverting loop sigmoid colostomy. The postoperative course was uneventful. After a 6-month follow-up, there was no recurrence, but the patient continued with fecal incontinence. This case underlines the importance of the Altemeier procedure as treatment in the patient with a strangulated prolapsed rectal segment.     

Hybrid EANN-EA System for the Primary Estimation of Cardiometabolic Risk

The most important part of the early prevention of atherosclerosis and cardiovascular diseases is the estimation of the cardiometabolic risk (CMR). The CMR estimation can be divided into two phases. The first phase is called primary estimation of CMR (PE-CMR) and includes solely diagnostic methods that are non-invasive, easily-obtained, and low-cost. Since cardiovascular diseases are among the main causes of death in the world, it would be significant for regional health strategies to develop an intelligent software system for PE-CMR that would save time and money by extracting the persons with potentially higher CMR and conducting complete tests only on them. The development of such a software system has few limitations - dataset can be very large, data can not be collected at the same time and the same place (eg. data can be collected at different health institutions) and data of some other region are not applicable since every population has own features. This paper presents a MATLAB solution for PE-CMR based on the ensemble of well-learned artificial neural networks guided by evolutionary algorithm or shortly EANN-EA system. Our solution is suitable for research of CMR in population of some region and its accuracy is above 90 %.     

Impact of treatment on survival of patients with secondary glioblastoma

Data concerning treatment of secondary glioblastoma evolving from previously treated WHO II or III grade tumors are very scarce. The aim of this study was to evaluate the impact of surgical resection and adjuvant treatment on survival in patients with secondary glioblastoma. Thirty-nine patients with secondary glioblastoma evolving from previously treated lower grade gliomas between 2004 and 2015 were included. We evaluated the extent of resection, pathological parameters, adjuvant treatment, as well as survival after malignant transformation. The primary tumor grade was WHO II in 16 (41.0%) and WHO III in 23 (59.0%) patients. Median age was 43 years (range 23–67). Median KPS was 80 (range 60–100) before surgery, and 70 (range 50–100) after surgery. Gross total resection (GTR) of contrast-enhancing disease was achieved in 19 (48.7%) patients. Adjuvant treatment was radio-chemotherapy in 23 (59.0%), radiotherapy in three (7.7%), chemotherapy in five (12.8%) and none in eight (20.5%) patients. Median survival was 11 months (range 1–35) in the entire group. Time since initial diagnosis and previous treatment did not correlate with survival after glioblastoma. Failed GTR, poor KPS after surgery, and no adjuvant treatment were prognostic factors for shorter survival in univariate analysis (p?<?0.0001, p?=?0.028 and p?=?0.003). In selected patients, complete resection and adjuvant treatment may prolong survival in spite of multiple previous therapies.
