Uncovering the Impact of Lymphadenectomy in Advanced Gastric Cancer: A Comprehensive Review.

Gastric cancer is a significant health concern worldwide, and lymphadenectomy plays a crucial role in its treatment. However, there is ongoing debate regarding the optimal approach-D1 or D2 lymphadenectomy. This paper aims to synthesize the available evidence by conducting a comprehensive literature review and comparing the advantages and disadvantages of both techniques. The analysis includes studies, clinical trials, and systematic reviews that assess survival outcomes, morbidity, and quality of life. The selected studies revealed different outcomes associated with D1 and D2 lymphadenectomy, including lymph node harvest, disease control, recurrence rates, and overall survival. Postoperative complications also varied between the two techniques. These findings highlight the complex considerations involved in selecting the most suitable lymphadenectomy approach for individual patients. Therefore, the decision requires an individualized assessment that considers the potential benefits and risks of D1 and D2 techniques. A collaborative approach involving interdisciplinary teams is crucial for developing personalized treatment plans that optimize both oncological outcomes and postoperative quality of life.

Primary PCI and Mental Health: A 12-Month Follow-Up Study.

The research article highlights the significance of acute myocardial infarction (AMI) and its impact on depression and anxiety among patients' post-primary percutaneous coronary interventions (PCI). The study aims to determine the frequency of depression and anxiety occurrence in patients with acute myocardial infarction after primary PCI. The objective of this study is to investigate the frequency of depression and anxiety in patients with acute myocardial infarction after primary PCI. The method used in the study involved the collection of data from 88 patients with acute myocardial infarction who underwent primary PCI treatment. The patients were tested before PCI and then at intervals of 1 month, 6 months, and 12 months post-PCI using the Hamilton Depression Scale (HAM-D17) and the Hamilton Anxiety Scale (HAM-A) to identify depression and anxiety symptoms, respectively. The study performed a comprehensive analysis of the collected data to determine the frequency of depression and anxiety occurrence in post-PCI patients. The study found evidence that primary PCI reduces depression and anxiety in patients who have experienced a myocardial infarction. However, mental health issues continue to be a significant psychological concern for patients post-PCI, impacting their lifestyle, self-care, and treatment adherence. The study suggests that healthcare providers should actively screen and manage psychiatric disorders in patients who have suffered from AMI as they are at an increased risk of mental disorders. In conclusion, the study indicates that depression and anxiety are common issues in acute myocardial infarction survivors, and interventions addressing these conditions should be a routine part of care. The study highlights the need for healthcare providers to be aware of the increased risk of mental disorders in individuals who have suffered from AMI. Understanding the impact of anxiety and depression on post-PCI patients is essential for the development of effective interventions that support patients' recovery.

Perinatal Exposure to HIV Infection: The Experience of Craiova Regional Centre, Romania.

BACKGROUND AND OBJECTIVES: HIV infection in pregnant women can be responsible for a number of consequences during pregnancy, such as: maternal anaemia, miscarriage, low birth weight, and preterm birth. The objectives of this study were to determine the maternal-foetal transmission rate of HIV among pregnant women living with HIV from Craiova Regional Centre in order to assess the risk factors for mother-to-child transmission of HIV and to identify the characteristics of newborns perinatally exposed to HIV. MATERIALS AND METHODS: A retrospective study was conducted between 1 January 2011 and 31 December 2020, including children born to HIV-positive mothers. RESULTS: The studied group included 138 newborns and was divided into two subgroups: group A, which included 10 HIV-infected infants; and group B, which included 128 uninfected infants. The mother-to-child transmission rate was 3.5% for women to whom all prophylaxis standards were applied. We found a statistically significant correlation between the level of maternal HIV viremia and perinatal HIV transmission (p = 0.01). Preterm birth and low birth weight were associated with perinatal transmission of the infection. CONCLUSIONS: Perinatal transmission of HIV infection during our study was associated with inconsistent application of screening for HIV infection among pregnant women, lack of antiretroviral therapy, poor adherence to treatment, and detectable HIV viral load during pregnancy.

Analysis of Some Behavioral Risk Factors in Relation to Acute Coronary Events.

The association of acute coronary events and behavioral risk factors is already known. Of these, smoking and alcohol consumption are the behavioral risk factors with the most intense impact in the occurrence of these events. The correct knowledge of the dynamics and their involvement in the evolution of acute coronary events remains of overwhelming importance in the light of current data. To achieve the purpose of this study data from three family medicine practices from the period November 2018 to May 2019 were corroborated. Anonymous questionnaires were applyed to the subjects. For this study, questions related to the habit of smoking and consuming alcohol were selected. The study aimed to analyze the associative relationships between acute coronary events and two of the most common behavioral risk factors, smoking and alcohol consumption. The highest prevalence of acute coronary events was observed in current smokers and in former smokers. The period of exposure to smoking showed that this is one of the variables most strongly associated with an increased risk of acute coronary events. Moderate consumption of wine or beer seems to have a weak association with acute coronary events, even weaker than those who do not consume at all suggesting a protective effect.

The Impact of the Associated Pathology in Acute Coronary Events.

Acute coronary events (ACE) are one of the main concerns for both clinical medicine and prophylaxis. The study aims to follow the frequency of the pathology associated with ACE and to establish its association with the occurrence of ACE. The study included 865 adult participants between the ages of 19-86. Subjects completed a complex questionnaire that included questions about health status. The study was conducted by applying the subjects to an anonymous questionnaire, in three family medicine practices between November 2018 to May 2019 and targeted healthy people. The frequencies of the following types of associated pathologies were evaluated: high blood pressure (HBP), hypercholesterolemia, stroke, diabetes, depression, stress. In hypertensive patients the prevalence of ACE was 6,99% (N=11) and in those not diagnosed with HBP of only 0,29% (N=2). The risk of ACE was 20 times higher than in those without HBP (RR=20,93; p<0.001). The prevalence of ACE was high among subjects with high cholesterol levels (21,43%) compared with those with normal values (3,03%; N=22), the risk of ACE being 7 times higher (RR=7,06; p<0.001). The prevalence of diabetes was more than four times higher in subjects with ACE (17,3%; N=9) compared with those without ACE (3,9%; N=32). Among those affected by diabetes, the prevalence of ACE was 21,95% (9/41), and risk of ACE in people with diabetes was four times higher (RR=4,21; p<0.001). Although cardiovascular disease is the most common pathology in the contemporary world, a number of comorbidities arise as ACE generators (hypertension, hypercholesterolemia, diabetes), along with psycho-emotional disorders such as depression, anxiety or stress, which outline, ensures, contributes or accelerates the progression to ACE.

Histopathological and immunohistochemical aspects of bone tissue in aseptic necrosis of the femoral head.

Femoral head osteonecrosis, also known as avascular necrosis, is a disease with a multifactorial etiology, characterized by a profound change of bone architecture, which leads to the diminishing of bone resistance and femoral head collapse. The main causes that lead to femoral head necrosis are represented by the decrease of local blood perfusion and increase of intraosseous pressure, because of an excessive development of adipose tissue in the areolas of the trabecular bone tissue in the femoral head. The histopathological and immunohistochemical (IHC) study performed by us showed that most of bone trabeculae were damaged by necrotic-involutive processes, their sizes being reduced, both regarding their length and their diameter; generally, the spans were thin, fragmented, distanced among them, which led to the occurrence of some large areolar cavities, full of conjunctive tissue, rich in adipocytes. Some of the residual bone spans even presented microfractures. In the structure of the trabecular bone tissue, numerous cavities showed lack of content, which indicates the death of osteocytes inside, while the endosteum appeared very thin, with few osteoprogenitor, flattened, difficult to highlight cells. The IHC study showed a low reaction of the bone reparatory processes and a reduced multiplication capacity of bone cells involved in the remodeling and remake of the diseased bone tissue. Nevertheless, there were identified numerous young conjunctive cells (fibroblasts, myofibroblasts), positive to proliferating cell nuclear antigen (PCNA), cells that have a high capacity of multiplication, participating in the formation of a fibrous conjunctive tissue (sclerous) instead of the damaged bone trabeculae. The formation of fibrous conjunctive tissue causes the reduction of mechanical resistance of the femoral head and its collapse. The IHC study of the microvascularization in the femoral head damaged by aseptic osteonecrosis showed the presence of a very low vascular system, both in the residual bone trabeculae and in the sclerous conjunctive tissue. Of the inflammatory cells present in the spongy bone tissue of the femoral head affected by osteonecrosis, the most numerous ones were the macrophages. Both macrophages and T- and B-lymphocytes had a heterogenous distribution.

A morpho-functional study using PEP/LVET ratio and global longitudinal strain in patients with dilated cardiomyopathy.

AIM: To assess left ventricular (LV) systolic function and morphology in patients with severe dilated cardiomyopathy (DCM), using both conventional and a complex technique, speckle-tracking echocardiography, and evaluate the correlation between pre-ejection period and left ventricular ejection period (PEP/LVET) ratio, global longitudinal strain (GLS), and severity of the condition. PATIENTS, MATERIALS AND METHODS: Seventeen patients were enrolled after rigorous criteria. Echocardiography was performed in conventional and speckle-tracking mode, in all patients with DCM, in sinus rhythm. LV dimensions, volumes and ejection fraction (LVEF) were measured. PEP/LVET ratio was obtained from apical 5-chamber axis and was defined as the time between QRS onset and LV ejection reported to LV ejection period. Speckle-tracking imaging was performed in offline mode and GLS was obtained from parasternal 4-, 3-, 2-chamber apical view, by averaging longitudinal peak systolic strain of all 17 LV-segments. RESULTS: New York Heart Association (NYHA) functional class correlated significantly with LVEF (-0.82; p=0.0006), PEP/LVET (0.86; p=0.001) or GLS (0.85; p=0.0002). Considerable correlations were between mitral regurgitation (MR) severity and LVEF (-0.65; p=0.01) or PEP/LVET (0.69; p=0.0059), but higher were between MR severity and GLS (0.76; p=0.0018). Tricuspid regurgitation (TR) grading correlated statistically with LVEF (-0.62; p=0.01), PEP/LVET and GLS (0.6; p=0.018; and 0.62; p=0.014, respectively). As opposed to the parameters in conventional echocardiography, GLS correlated with DCM etiology (p=0.0046) and with the gender (p=0.048). CONCLUSIONS: This study demonstrates that, in patients with DCM, assessment of cardiac dyssynchrony can be accurately accomplished by combining parameters in conventional and in speckle-tracking echocardiography.

Microglial voltage-gated sodium channels modulate cellular response in Alzheimer's disease--a new perspective on an old problem.

Alzheimer's disease (AD) determines gradual loss of cognition and memory function, eventually leading to clinical manifest dementia. The pathogenic mechanisms of AD remain elusive and treatment options unsatisfactory, targeting only symptoms like memory loss, behavior changes, sleep disorders and seizures. These therapies are not stopping the disease's progression, at their best they can only delay it. Accumulating evidence suggests that AD is associated with a microglial dysfunction. Microglia are resident immune cells that provide continuous surveillance within the brain. When excessively activated, microglial response can also have detrimental effects via the exacerbation of inflammatory processes and release of neurotoxic substances. Recently, it was recognized that microglia express voltage-gated ion channels, in particularly voltage-gated sodium channels (VGSC). Pharmacological block of VGSC has been attempted symptomatically in AD to control the epileptic features often associated with AD, as well as to relieve detrimental behavioral and psychological symptoms of dementia. The success of VGSC treatment in AD was unexpectedly variable, ranging from very beneficial to plain detrimental. This variability could not be satisfactorily explained solely by the neuronal effects. This article will try to discuss possible implication of microglial VGSC dysfunction in AD according to available data, own personal experience of the authors and propose a new way to investigate its possible implications.

Proatherogenic adipocytokines levels in metabolic syndrome.

INTRODUCTION: Metabolic syndrome was defined by IDF (International Federation for Diabetes, 2007) by abdominal obesity plus at least two of the following: high triglycerides, low HDL-cholesterol, hypertension, high levels of glucose or type II diabetes diagnosed. Obesity is associated with a high cardiovascular risk, abdominal obesity being the most aggressive form, because it secretes cytokines and hormones in comparison to subcutaneous adipose tissue. Adipocytokines secreted by adipose tissue are mediators of atherosclerosis and endothelial damage. MATERIALS AND METHODS: We studied a total of 80 subjects aged between 40 and 60 years with metabolic syndrome, in which the following adipocytokines values were determined: hs-CRP (turbidimetric method), IL-6, TNF-alpha, leptin (ELISA method), in comparison to a control group. RESULTS: The values of these adipocytokines were significantly higher in the studied group compared with the control group and correlated with increased levels of glucose (patients with type II diabetes or increased tolerance test) and with hyper-triglyceridemia. CONCLUSIONS: Patients with metabolic syndrome had increased levels of proatherogenic adipocytokines, particularly leptin, leptin-resistance representing the pathogenic link of obesity. The identification as early as possible of the metabolic syndrome patients allows effective monitoring and correction of cardiovascular risk factors, with the opportunity to reduce morbidity and mortality in young ages. In men, proatherogenic cytokines values presented higher values than in women, which prove the role of abdominal obesity in proatherogenic cytokines production. Although women have a higher percentage of adipose tissue, this is not primarily abdominal adipose tissue.

Oral mucosa self-graft in a patient with invasive conjunctival melanoma: a case report.

Conjunctival melanoma is a rare tumor, while malignant melanoma of the uveal tract is the most common primary intraocular tumor in adults. The authors highlighted the case of a 68-year-old male patient presented in June 2011 in the Ophthalmology Clinic of the Emergency County Hospital of Craiova, Romania, accusing foreign body sensation and the appearance of a tumor in the lower fornix of his right eye. The patient was clinically and paraclinically investigated, and clinically diagnosed with de novo malignant melanoma. The tumor was surgically excised and the lower fornix reconstructed with oral mucosa self-graft. Histopathological diagnosis was de novo, invasive, ulcerated malignant melanoma of the conjunctiva. Ki-67 immunohistochemical staining was also performed. After surgery, the patient was sent to the Oncology Department for specific treatment. Despite the histological poor prognosis factors present in our patient, two years after surgery and chemotherapy, the patient had no clinical sign of local or distance recurrent disease. Continuous ophthalmologic and oncological surveillance is necessary.
