Review on stroke induced depression

One of the frequent and dangerous aftereffects of stroke is post-stroke depression (PSD). About one in three stroke survivors had depression following their stroke. It had a significant impact on functional recovery, which resulted in a low standard of living. Even worse, there is a clear correlation between it and a high death rate. Our goal in doing this evaluation was to come up with a thorough and cohesive knowledge of PSD based on both recently released research and well-known works. We discovered that the incidence of PSD varies from 11 to 41% within a two-year period, based on a significant number of researches. The severity of the stroke, the location of the lesion, past history of depression, and other factors all has a role in the development of PSD. The DSM criteria are currently the primary basis for diagnosing PSD, and they are often coupled with different depression scales. However, there isn't a single, cohesive process that explains PSD which now include aberrant neurotrophic response, elevated inflammatory markers, lowered monoamine levels, glutamate-mediated excitotoxicity, and dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis. Pharmacotherapy and psychosocial therapies are currently used in the treatment of PSD. Even though researchers have made significant progress, many problems still need to be solved. In particular, the PSD's mechanism is not entirely understood.

Evaluation of orphan drug therapies and associated monitoring guidelines

Orphan drugs, designed for the treatment and prevention of rare medical conditions known as orphan diseases, are infrequently accessible due to their high costs and limited research. The prevalence of rare diseases varies across countries based on population demographics. The Food and Drug Administration (FDA) has approved over 770 drugs with 77 designations for orphan status. Some of these drugs, often discovered by the pharmaceutical industry, are both highly valuable and expensive. When using orphan drugs, specific parameters need to be monitored. Therapeutic monitoring should align with the patient's physical condition and the severity of the disease. This article aims to comprehensively examine the development of orphan drugs and their monitoring protocols.

Maternal near miss: a retrospective study in a tertiary care hospital at South India

Background: A maternal near miss (MNM) case is defined as a woman who nearly died but survived a complication that occurred during pregnancy, childbirth or within 42 days of termination of pregnancy. MNM situations tend to mirror the causes of maternal death. Hence, review of these cases has been found to help in the assessment of maternal health services. These cases are called as MNM or severe acute maternal morbidity (SAMM) and auditing these cases is called near miss audit (NMA).Methods: A retrospective study of 201 MNM cases over a period of 12 months from January 2023- December 2023. Demographic data were collected from MNM review form and records. Data studied and analyzed.Results: There were 11,340 deliveries and 11,126 live births during the study period out of which 201 MNM cases were studied. Haemorrhage followed by anemia was the most common cause of near miss events. The most common age group affected in the near miss cases in the present study was 20 to 35 years (80%). Majority of the cases were referred from the nearby PHCs and government hospitals.Conclusions: Most maternal deaths are preventable by optimal utilization of existing MCH facilities, identifying the bottleneck in health delivery system, early identification of high-risk pregnancy and therein timely referral to tertiary care centre.

Acute fatty liver of pregnancy: cases series and review of the literature

Acute fatty liver of pregnancy (AFLP) is a condition that occurs during the third trimester of pregnancy, typically manifesting around 36 weeks of gestation. It represents a critical obstetric emergency with considerable neonatal mortality. To manage AFLP disease, a multidisciplinary approach is essential which helps meaningfully in the improvement of its prognosis during the post-partum period. Historically, it was considered a fatal disease for both mother and fetus. Nowadays, the prognosis is improved by rapid diagnosis, early delivery and administration of treatment. We reported three cases of Moroccan women diagnosed with AFLP in our hospital who received a multi-disciplinary care with good prognosis. The first and third parturient gave birth by vaginal delivery and the second one by caesarean section.

Assessment of severity of community acquired pneumonia by paediatric infectious diseases society and clinical and radiological profile in 0-5 year age group

Background: The WHO estimates that ARI, mostly in the form of CAP, is the leading cause of death in children under five, killing over 2 million children annually. The present study's PEWS score and PIDS severity criteria were undertaken to know the clinical and radiological profile of patients with Pneumonia and to categorize these patients with PEWS score and PIDS criteria to redefine their severity and assess the management and outcomes.Methods: Patients aged between 0 to 5 years who presented with cough complaints and respiration difficulty were assessed. The criteria for ICU admission is the presence of more than 2 minor criteria or one of the major criteria. PIDS criteria for CAP recommends ICU admission or continuous monitoring for children in ED.Results: A prospective observational study of 104 children with CAP was included, and their pneumonia was evaluated using PIDS criteria. The patients were categorized for pneumonia according to PIDS criteria. 32.69% of children were classified as severe CAP (p value=0.02). This difference between non-severe and severe Pneumonia is considered to be statistically significant in which patients classified as severe CAP. Conclusions: The patients were categorized for Pneumonia according to PIDS criteria. 32.69% of children were classified as severe CAP (p value=0.02). This difference between non-severe and severe Pneumonia is considered to be statistically significant in which patients classified as severe CAP needed vigorous management in emergency department followed by ICU management.

In this article, the mechanism of donor liver injury during cold ischemia, the classification and evolution of donor liver preservation fluid were summarized, the development direction and challenges of donor liver preservation fluid were discussed, aiming to provide novel ideas and references for the research and development of donor liver preservation fluid.

The question of death criteria in human organ donation / 器官移植

Donation after death is the most important ethical principle to carry out organ donation after citizens’ death. The newly-revised <i>Regulations on Human Organ Donation and Transplantation</i> does not define death, and avoids the key question of “whether to recognize brain death”. Certain legal risks or damages to the rights and interests of donors may exist in organ donation. Death is an inevitable part of human life. It is necessary to establish specific criteria, which is also the only approach, to define death in any era. Death criteria are established based on the view of death, and restricted by the development level of productive forces and other social factors. The determination of death criteria hugely varies between China and the West. To standardize organ donation and transplantation and promote high-quality development of organ donation, medical staff must adhere to the principle of pure motivation, take informed consents as the premise, respect the donors' and their close relatives' rights to choose their own death criteria, strictly follow the death judgment procedures and operating norms, and ensure the scientificity, accuracy and fairness of death determination.

Evolution and considerations of diagnostic criteria for neonatal acute respiratory distress syndrome / 解放军医学杂志

Since acute respiratory distress syndrome(ARDS)was firstly reported in 1967,the diagnostic criteria and classification standard have evolved continually.Neonatal ARDS has drawn increasing attention in recent years,while research on neonatal ARDS has proceeded slowly,partly because of ambiguity in the definitions and diagnostic criteria of neonatal ARDS.In this comment,we overview the application of the Berlin definition made in 2012,the Montreux definition made in 2017,and the definition of pediatric ARDS update by the Second Pediatric Acute Lung Injury Consensus Conference made in 2023(PALICC-2 definition)in neonatal ARDS,then compare the similarities and differences among the three definitions.Finally,the differences in classification standard,triggers,morbidity,mortality,poor prognosis,and treatment among the three definitions for neonatal ARDS were analyzed,and the research directions in the future of the definition for neonatal ARDS were proposed.

Current Situation and Suggestion of Comprehensive Clinical Evaluation of Medical Products in China in Recent Ten Years / 中医杂志

Through analyzing the current situation of clinical comprehensive evaluation researches of domestic medical products from 2013 to 2023， it is found that there is a phenomenon of “four more， four less”. Specifically， there is a greater emphasis on conducting research on drug clinical comprehensive evaluation， but fewer comprehensive evaluation opinions provided； more research data come from publicly available information， but fewer derived from real world； more options for similar reference drugs， but less pre-defined research on reference drugs； the research process involves more steps， yet there are fewer studies strictly implementing quality control. Based on this， suggestions are proposed in three aspects： improving the quality of clinical comprehensive evaluation of medical products， enhancing the transformation and dissemination of results， and improving the standardization of clinical comprehensive evaluation of medical products. Regarding the current state of clinical comprehensive evaluation research on Chinese patent medicine， reflections are presented on elevating original research evidence and highlighting the characteristics and advantages of Chinese patent medicine， so as to promote better transformation and application of the results of clinical comprehensive evaluation of medical products.
