ABSTRACT

American Indians and Alaska Natives (AI/AN) have consistently exhibited suicide rates that surpass all other racial and ethnic groups in the United States. However, not much has been published regarding the epidemiology of AI/AN youth suicides. The objectives of this study on AI/AN adolescents were to assess the prevalence of suicidal thoughts and behaviors by age and gender, assess the number of years of life lost to suicide before the age of 80, and assess the most common methods used to commit suicide by AI/AN adolescents. Data utilized for this study were from the national Youth Risk Behavior Surveys and the Web-Based Injury Statistics Query and Reporting System. We conducted a cross-sectional descriptive analysis of the suicide-related data from years 2015, 2017, 2019, and 2021. We found AI/AN adolescents averaged one in four contemplated suicides, one in five planned suicides, and one in six attempted suicides. A total of 257 adolescents committed suicide during the study period where the majority (62.5%) were observed in males and suicides were more common in older adolescents. AI/AN adolescents had the highest crude suicide death rate of any racial or ethnic group and the most common methods used to commit suicide were suffocation (57.5%) and firearms (35.5%). AI/ AN adolescents lost almost 16,000 years of potential life during the four years of the study and the majority were lost by males. Professionals and policymakers desiring to reduce suicidal thoughts and behaviors among AI/AN adolescents need to focus more of their efforts on providing youths with resilience factors to establish sufficient ego strength in them to deal with all types of stressors. Concurrently, federal, state, and tribal leaders need to work together to improve the social and economic circumstances faced by many AI/AN families and children.

ABSTRACT

AIM: To characterize the immunohistochemical expression of MDM2, Bcl-2, SATB2 and Ki-67 in histological variants of unicystic ameloblastoma (UA).

METHODOLOGY: Following the ethical approval, forty (40) patients with unicystic ameloblastoma were retrieved from the archives and subjected to immunohistochemistry (IHC). Sociodemographic and clinical data were also retrieved. The results were entered into a Microsoft Excel spreadsheet and analyzed using SPSS software.

RESULTS: Human tooth germs, which served as the control, showed moderate expression of Bcl-2 and MDM2 with slight proliferative activity in ameloblasts and moderate expression of SATB2 in ectomesenchyme and odontoblasts. Luminal UA (Type 1) showed low Ki-67 index and negative to mild Bcl-2 and MDM2 expression, whilst Type 1.2 (luminal and intraluminal), Type 1.2.3 (luminal, intraluminal and mural), and Type 1.3 (luminal and mural), including the recurrent cases, showed moderate to intense expression with high mean Ki-67 index. The difference between the study groups was statistically significant (p value < 0.001). No expression of SATB2 was noted in any histological variant of UA. Furthermore, no significant differences were noted in age, gender, site and location between the groups.

CONCLUSION: In contrast to luminal variant of UA, mural±intraluminal variants and recurrent cases demonstrate higher expression of Bcl-2 and MDM2 with higher mean Ki-67 index. It may thus be prudent to provide aggressive treatment for cases, not just with mural follicles but also for the patients with intraluminal plexiform proliferation, to prevent recurrence and improve patient outcomes.

ABSTRACT

Cardiac magnetic resonance (CMR) enables the assessment of tissue characteristics of the myocardium. Changes in the extracellular volume (ECV) and fibrosis volume (FV) of the myocardium are sensitive and early pathogenetic markers and have prognostic significance. The aim of the study was to assess ECV and FV of left ventricular myocardium in T1 mapping sequence in patients with a history of SARS-CoV-2 infection, considering vaccination status against COVID-19. The study group consisted of 97 patients (52.54 ± 8.31 years, 53% women and 47% men). The participants were divided into three subgroups: A) patients with a history of symptomatic SARS-CoV-2 infection, unvaccinated against COVID-19 (n = 39), B) patients with a history of symptomatic SARS-CoV-2 infection, with a full vaccination schedule against COVID-19 (n = 22), and C) persons without a history of SARS-CoV-2 infection constituting the control subgroup (C, n = 36). All patients underwent 1.5 T cardiac magnetic resonance. In subgroup A compared to subgroups B and C, both the ECV whole myocardium and ECV segments 2, 5-6, 8, and 10-11 were statistically significantly higher. In addition, the ECV segment 16 was statistically significantly higher in subgroup A than in subgroup C. Also, the FV whole myocardium was statistically significantly higher in subgroup A in comparison to subgroups B and C. There were no significant differences in ECV and FV between subgroups B and C. In summary, unvaccinated against COVID-19 patients with a history of symptomatic SARS-CoV-2 infection have higher myocardial ECV and FV values in the T1 mapping sequence, compared to those without COVID-19 and those suffering from COVID-19, previously vaccinated with the full vaccination schedule.

ABSTRACT

BACKGROUND: Prehabilitation, which includes nutritional and exercise therapies, is recommended for patients before surgery to improve physical and cognitive functions. This study aimed to identify the awareness, understanding, and issues among surgeons and anesthesiologists regarding the implementation of prehabilitation.

METHODS: We conducted a survey on prehabilitation targeting surgeons and anesthesiologists working at a university hospital and two private hospitals. The survey collection period was set for 1 month, commencing on February 5, 2024. Descriptive statistics were employed to summarize the characteristics of the participants.

RESULTS: A total of 254 surgeons and 49 anesthesiologists from three hospitals participated, with a response rate of 61.7%. Regarding the understanding of prehabilitation, 16.7% of anesthesiologists and only 2% of surgeons had a good grasp of its content. When enquired about the necessity of prehabilitation, 100% of anesthesiologists indicated it as necessary or somewhat necessary, whereas 98.7% of surgeons responded similarly. Several barriers to the implementation of prehabilitation were identified, with the most common reason being the busy schedule of outpatient services.

CONCLUSION: This study highlights that while both surgeons and anesthesiologists recognize the importance of prehabilitation, significant challenges exist in its practical implementation. This underscores the need for simple explanatory tools for patients, the introduction of remote care options, and simple orders to relevant departments, which are essential and require multidisciplinary collaboration.

ABSTRACT

OBJECTIVE: To evaluate mortality for Alzheimer’s Disease (AD) in Italy over more than three decades (1980-2015) and discuss the possible role of general and specific contributing factors.

METHODS: Mortality data were extracted by the Italian National Institute of Statistics: crude mortality rates were computed for sex and age, considering the whole country and its five main geographical sub-areas. Rates were standardized in two ways: directly (annual mortality rates AMRs) and indirectly (standardized mortality rates, SMRs). SMRs were then used to evaluate geographical differences; to study mortality trend, AMRs and joinpoint linear regression analysis were used.

RESULTS: Considering the entire period and the whole country, mortality rates were similar for females and males and for geographical regions, with the exception of the older age groups where mortality for AD in females slightly prevailed. In these older patients, a steep increase of mortality was seen starting from the current century. The increase in male mortality mirrored the national trend in North-West and Central Italy, but not in North-East, South, and the Islands, where it did not surge until the mid to late 1990s.

CONCLUSIONS: the general increase of mortality is in line with international data and it reflects the increasing prevalence of the disease, likely due to increasing longevity, and to improvements in diagnostic accuracy. In addition, the accuracy of death certificate compilation could account for both geographical and temporal differences. Currently available drugs for AD do not seem to have an impact on mortality rates.

ABSTRACT

BACKGROUND: The existing evidence on the effect of dietary supplements for preventing migraines has generated conflicting results.

METHODS: We assessed alterations in migraine clinical features corresponding to the intake of dietary supplements. Our main outcomes included the frequency (number of attacks), duration (in hours), the severity (intensity) and the monthly migraine days. Using a dose-response meta-analysis, we estimated the dose-dependent impact. The certainty of evidence was evaluated using the GRADE tool.

RESULTS: Finally, twenty-two trials were included in the systematic review and meta-analysis. Magnesium supplementation reduced migraine attacks (mean difference (MD) = -2.51), severity (MD = -0.88), and the monthly migraine days (MD = -1.66) compared with the control group. CoQ10 decreased the frequency (MD = -1.73), severity (MD = -1.35), and duration of migraine (MD = -1.72). Riboflavin decreased attack frequency (MD = -1.34). Alpha-lipoic acid decreased attack frequency (MD = -1.24) and severity (MD = -0.38). Probiotics decreased the frequency (MD = -1.16), severity (MD = -1.07) and the monthly migraine days (MD = -3.02). Vitamin D reduced migraine frequency (MD = -1.69) and the monthly migraine days (MD = -2.41). In adults, compared with placebo, these supplements did not significantly affect other outcomes, and omega-3 supplementation did not yield a statistically significant reduction in any of these outcomes.

CONCLUSION: The use of certain dietary supplements has resulted in a significant decrease in migraine prophylaxis. Further clinical trials of high quality appear to be beneficial.
