Study on the correlation between fatty liver index and the outcome of high normal blood pressure

Objective: To analyze the correlation between fatty liver index (FLI) and the outcomes of individuals with high normal blood pressure. Methods: In this retrospective cohort study, data from the follow-up population of the Beijing branch of the Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal (REACTION) study conducted from December 2011 to August 2012 were selected. Obtain indicators such as height, weight, waist circumference, fasting blood glucose, 2-h postprandial blood glucose, triglycerides, high-density lipoprotein cholesterol, and glutamyl transpeptidase were measured, and the FLI was calculated. The population with high normal blood pressure was divided into the FLI<30 group (1 822 cases); 30≤FLI<60 group (1 026 cases); and FLI≥60 group (473 cases) based on FLI levels. The blood pressure outcome data from the follow-up survey of this population from April 2015 to September 2015 were collected. Single factor analysis of variance was used for intergroup comparison, and logistic regression was used to analyze the correlation between FLI and the outcome of high normal blood pressure in the population. Results: The FLI was an independent influencing factor for their conversion to normal blood pressure (all P<0.01). Among all observed populations, the likelihood of conversion to normal blood pressure in the 30≤FLI<60 group and FLI≥60 group was 0.63 (95%CI 0.51-0.78) and 0.61 (95%CI 0.45-0.82) of the FLI<30 group, respectively. In the population of 40≤age<60 years, this likelihood was 0.60 (95%CI 0.47-0.76) and 0.57 (95%CI 0.41-0.79), respectively. FLI is not an independent influencing factor for the conversion to normal blood pressure in individuals aged over 60 years (P=0.161). FLI is an independent risk factor for hypertension (all P<0.05). Among all observed populations and population of 40≤age<60 years and age>60 years, the risk of hypertension in the 30≤FLI<60 group and FLI≥60 group was 1.49 times (95%CI 1.23-1.80) and 1.54 times (95%CI 1.19-1.98); 1.41 times (95%CI 1.13-1.75) and 1.38 times (95%CI 1.04-1.83); and 1.75 times (95%CI 1.22-2.53) and 2.10 times (95%CI 1.24-3.58) of the FLI<30 group, respectively. Conclusions: There is a correlation between FLI levels and future outcomes of individuals with normal high blood pressure. Although people with higher FLI are more likely to develop hypertension, those with higher FLI are also less likely to develop normal blood pressure in the 40≤age<60-year group.

Nonrestorative sleep and its association with insomnia severity, sleep debt, and social jetlag in adults: Variations in relevant factors among age groups

ObjectiveNonrestorative sleep (NRS) is unrefreshing sleep that is harmful to mental and physical health. Although few studies have reported the relationship between NRS and sleep problems, none have evaluated this relationship by age group. This study aimed to determine whether NRS could be associated with insomnia severity, sleep debt, and social jetlag and whether this relationship would vary with age. MethodsThe 1592 participants were allocated into age groups: 18–25 years (n = 317), 26–40 years (n = 405), 41–65 years (n = 454), and >65 years (n = 416). The study used Restorative Sleep Questionnaire to assess NRS, Athens Insomnia Scale to assess insomnia severity, Sleep Debt Index to assess sleep debt, and the absolute difference in midpoints of sleep between weekdays and days off to assess social jetlag. ResultsLogistic regression analysis was performed to determine the association between NRS and sleep problems. In the 18–25-year group, insomnia severity, sleep debt of ≥2 h, and social jetlag of ≥2 h; in the 26–40-year group, insomnia severity and sleep debt of ≥2 h; in the 41–65-year group, insomnia severity and sleep debt of ≥2 h; and in the >65-year group, insomnia severity were significantly associated with NRS. ConclusionNRS was associated with insomnia severity in all age groups, with sleep debt in the young and working-age groups and social jetlag in the young age group. Different approaches to improving the NRS are required for different age groups.

Eosinophilic esophagitis: Does age matter?

Eosinophilic esophagitis (EoE) is often diagnosed in school-age children between 6- and 9-year-old. There is less known about those who are diagnosed with EoE that are younger than 6 years old. The objective of this study is to compare clinical presentation, comorbidities, and outcomes based on age at diagnosis of EoE. Single-center retrospective chart review of children (<18 years) diagnosed with EoE between 2005 and 2020. We recorded demographics, clinical presentation, family history, past medical history, treatment, and endoscopic findings. Children in this cohort were classified based on age into three age groups: <2 years, 2-<6 years, and 6-<18 years. We identified 256 children with EoE, the mean age (SD) at the time of diagnosis was 9 (5.2) years and 184 (72%) were male. We had 164 (64%) patients with available follow-up esophagogastroduodenoscopies (EGD) data (495 EGDs in total) of those 99/164 (60%) reached mucosal remission. In the very young children (<2 years) vomiting was the most common presentation, while poor weight gain was seen more in the 2-<6-year group in comparison to the >6-years. Food impaction and abdominal pain were most likely to present in older children 6-18 years. Combination therapy, as opposed to a single therapy, induced remission at a higher frequency in the <6-year group in comparison to the 6-<18-year group (85% vs. 66%). EoE should be considered in younger children presenting with feeding difficulty and poor weight gain. Combination therapy seems to be more effective in younger children with EoE, but further studies with bigger sample size are needed to study the efficacy of the different combination therapies.

Perioperative treatments for and postoperative activity of daily living of patients with early-stage breast cancer according to age group: A retrospective observational study

IntroductionThe number of older patients with breast cancer is increasing worldwide. However, no studies have clarified to what extent activities of daily living (ADL) decline in older patients after surgery. This study aimed to identify perioperative treatments and the proportion of patients with a postoperative decline in ADL among those with early-stage breast cancer, according to age groups (<65, 65–74, ≥75 years). Materials and methodsThis retrospective study used healthcare utilization data of women aged ≥40 years who were diagnosed with breast cancer in 431 Japanese hospitals. Patients who underwent breast conserving surgery and mastectomy at clinical stages 0–III were included. ADL were assessed using the Barthel index (100 points indicated independent ADL). ResultsOverall, 37,161 patients were analyzed, including 17,313 undergoing a breast conserving surgery and 19,848 undergoing a mastectomy. The difference in the proportion of patients with a postoperative decline in ADL between those in the <65-year and ≥75-year group who underwent mastectomy was approximately 1%. In each age group, a higher proportion of patients received adjuvant chemotherapy (9.4–27.5% for breast conserving surgery; 15.6–40.3% for mastectomy) than neoadjuvant chemotherapy (breast conserving surgery, 2.1–12.0%; mastectomy, 3.0–18.1%). A lower proportion of patients in the ≥75-year group underwent radiotherapy than that in the <65-year group. ConclusionPhysical burden of surgery was low in both younger and older patients. Low proportions of patients in the ≥75-year group who underwent surgery received neoadjuvant and adjuvant chemotherapy and adjuvant radiotherapy. Healthcare providers should inform this to patients.

Changes in the epidemiological indicators of type 1 diabetes mellitus in children and adolescents living in the closed administrative and territorial entity

Type 1 diabetes mellitus (DM) (T1DM) in children remains one of the most important problems of endocrinology due to the constant increase in new cases of the disease. Objective. To analyze the main epidemiological indicators (morbidity and incidence rates) of DM among children and adolescents who live in the closed administrative-territorial entity (CATE) and to compare the data from the federal DM register with those in that of the Krasnoyarsk Territory and Russian Federation to assess trends and to plan further work on the provision of specialized medical care, as well as the rational use of material and human resources. Material and methods. The data of regional DM register in the past 10 years (2010–2021), as well as those in the outpatient records of T1DM who lived in the CATE of the Krasnoyarsk Territory were studied and analyzed. Morbidity and incidence rates were calculated; a comparative analysis was carried out. The data available in the register and medical documentation were analyzed and there was evidence for the age and gender characteristics of a manifestation of the disease. Results. The incidence of DM among the pediatric population in the CATE exceeded the average statistical indicators in the Krasnoyarsk Territory. The age structure of sick children was dominated by a 15–18-year group. The gender characteristics included higher morbidity rates among the boys in the entire group of the examinees. An assessment of the incidence of DM revealed its stable increase with the maximum figure by 2021. Conclusion. The presented data and the analysis of indicators can be used in further observations and for the comparison with future data on the incidence of DM in children in the CATEs.

Immunological Findings in a Group of Individuals Who Were Poor or Non-Responders to Standard Two-Dose SARS-CoV-2 Vaccines.

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been declared a pandemic. However, data on the poor or non-responders to SARS-CoV-2 vaccines in the general population are limited. The objective of this study was to comprehensively compare the immunological characteristics of poor or non-responders to SARS-CoV-2 vaccines in the 18-59-year group with those in the ≥60-year group using internationally recognized cut-off values. The main outcome was effective seroconversion characterized by an anti-SARS-CoV-2 spike IgG level of at least a four-fold increase from baseline. Profiling of naïve immune cells was analyzed prior to vaccination to demonstrate baseline immunity. The outcomes of effective seroconversion in patients aged 18-59 years with those in patients aged ≥60 years were compared. The quantitative level of anti-spike IgG was significantly lower in individuals aged ≥60 and men aged 18-59 years. There were 7.5% of poor or non-responders among the 18-59 years and 11.7% of poor or non-responders in the ≥60 years using a four-fold increase parameter. There were 37.0-58.1% with low lymphocyte count (<1000/mm3), 33.3-45.2% with low CD4 cell counts (<500/mm3), and 74.1-96.8% with low B cell counts (<100/mm3) in the non-seroconversion group. An individual with an anti-SARS-CoV-2 spike IgG titer below 50 BAU/mL might be considered a poor or non-responder between 14 and 90 days after the last vaccine dose. Booster vaccination or additional protective measures should be recommended to poor or non-responders as soon as possible to reduce disease severity and mortality.

Trends in the Treatment of Adolescent Clavicle Fractures: Are We Listening to the Evidence?

From 1999 to 2011, studies demonstrated an increasing trend toward surgical management of adolescent clavicle fractures. The purpose of this study was to examine more recent trends of surgical management of closed clavicle fractures in adolescent patients over the past decade. A retrospective cohort study was conducted using the PearlDiver database. Patients with clavicle fractures from 2011 to 2021 were identified and stratified by age, sex, and year of their fracture. Categorical variables were compared with a chi square test, and continuous variables were compared with the Welch t test or Mann-Whitney U test. Overall, there was a significant increase in the percentage of patients surgically treated by open reduction and internal fixation from 2016 to 2021 compared with 2011 to 2015 (8.58% vs. 7.34%, P < 0.001). When stratified by age, both the 10 to 14-year group (3.80% vs. 3.10%, P < 0.001) and the 15 to 18-year group (15.41% vs. 12.84%, P < 0.001) demonstrated significant increases in the percentage of patients surgically treated. Despite increasing literature demonstrating high revision surgery rates for surgical treatment of adolescent clavicle fractures with no difference in functional outcomes, this study demonstrated a notable increase in the rate of surgical treatment of adolescent clavicle fractures from 2011 to 2021 in the United States.

Ground level falls: computed tomography findings and clinical outcomes by age groups.

This study aimed to determine injury patterns in ground level falls (GLFs) and investigate the effect of age on the severity of injury. We retrospectively identified 4,712 patients who presented to a Level 1 trauma center due to GLFs and analyzed the data of 1,214 patients who underwent computed tomography (CT). Demographics, torso examination findings, and injuries detected on CT were recorded. To investigate the effect of age on injury severity, the patients were grouped as those aged <65 and ≥65 years. The mean age was 57 years, and 55.20% of the patients were female. The mortality rate was 0.50%. Injury was detected in 489 (40.30%) patients on CT. Fractures were the most common injury type. Traumatic intracranial hemorrhage was detected in 32 (2.60%) patients. Only three (0.20%) of the 63 patients with rib fractures had concomitant lung injury. The negative predictive value of the physical examination (PE) was 95.80% for chest injury. Intra-abdominal injury was not detected in any of the 116 patients who underwent abdominal CT. Hospitalization was also higher in the ≥65-year group (p<0.001). All mortalities (n=6) were seen in patients aged ≥65 years. Our results indicate that GLFs cause more injuries in the elderly, resulting in more hospitalizations and mortality. Normal PE findings may reduce the need for whole-body CT in GLF patients who are conscious, cooperative, and oriented.

Age-Dependent Occurrence of Prostate Cancer in an African-American Patient Population of Predominantly West Indian Origins

In a prior study of the occurrence of prostate cancer in a unique population of African American patients many of whom have West Indian ancestry, we found that seventy percent of patients screened for prostate were found to have this disease and that, of the seventy percent diagnosed with prostate cancer, 70 percent were found to have high-grade (Gleason score ≥ 7) disease. Overall, therefore, high-grade prostate cancer was found in over 50 percent of all cancers diagnosed, a rate of occurrence that was significantly higher than the corresponding ones for other demographic populations. Since the average age for screening was 65, the same as in other demographic groups, we conjectured that earlier screening of our patients might eliminate many of these high-grade tumors. To validate this hypothesis, we have now examined the rates of occurrence of high-grade prostate cancers in successive age groups, i.e., 40-&lt;50, 50-&lt;60, 60-&lt;70, 70-&lt;80 and &gt;80. Surprisingly, we found that, already in the 50-&lt;60 age group, the frequency of occurrence of high-grade cancers is &gt;50%. (The number of patients in the 40-&lt;50, i.e.,12 and &gt;80, i.e., 6, were too small to be accurately evaluated.) Since the high rate of high-grade cancer occurs in the 50-&lt;60-year group, we conclude that screening for prostate cancer should be performed on our patients at significantly earlier ages such as 40-&lt;50. Also, in view of the expectation that high-grade tumors would increase with increasing age, a second unexpected finding was that the percentage of high-grade tumors was statistically the same at &gt;50 percent in the 50-&lt;60, 60-&lt;70 and 70-&lt;80 age groups. This result could be explained if there was a concurrent increase in low-grade tumors occurring in older patients suggesting that continued, persistent screening is necessary even in advanced age groups. We further found that the mean Gleason score of the 50-&lt;60 and 60-&lt;70 age groups is statistically the same, suggesting that the high-grade tumors are "stable". However, there is a statistically significant increase in Gleason scores between the 70-&lt;80 age group and the two lower age groups which is associated with a large increase in Gleason 9 cancers in the 70-&lt;80 age group and a concurrent, marked decrease in Gleason 7 cancers, suggesting significant recurrent progression of high-grade tumors in this age group.

Marital status, immigration, and reproductive health among adolescent mothers in Canada, 1990–2018: A population-based, observational study

Immigrants to Canada increasingly come from regions where child marriage (<18 years) is prevalent. We described the prevalence, demographic characteristics, and reproductive health correlates of marriage among births to Canadian-born and foreign-born adolescent mothers. Using Canadian birth registrations from 1990 to 2018, marriage prevalence, parental birth region, and parental age gap were examined by maternal birthplace (Canada and 12 world regions) among births to mothers <18 years. Adjusted odds ratios (AORs) of preterm birth (PTB), small for gestational age (SGA), and repeat birth were estimated for the joint associations of adolescent maternal age group (<18-year, 18–19-year, and 20–24-year), marriage, and nativity status (n = 1,904,200). Depending on maternal birthplace, marital births represented 2.6% to 81.8% of births to mothers <18 years. Marriage among mothers giving birth at <18 years was associated with higher proportions of parents from the same birthplace and larger parental age gaps. AORs of PTB tended to increase with lower maternal age. AORs of SGA were generally higher among births to foreign-born mothers. Marriage was associated with lower AORs of PTB and SGA among births to Canadian-born mothers and PTB among births to foreign-born mothers in the older adolescent age groups, but no association existed in the <18-year group. Marriage was positively associated with repeat birth in all adolescent age groups, with stronger associations in the <18-year group. The reproductive health correlates of marriage are similar between births to Canadian-born and foreign-born mothers <18 years but some differ between births to mothers <18 years and those to older adolescent mothers.

Evaluation of differences across age groups in the incidence, severity, and recovery of concussion in adolescent student-athletes from 2009 to 2019.

Concussion incidence is known to be highest in children and adolescents; however, there is conflicting evidence about the effect of age on concussion risk and recovery within the adolescent age range. The heterogeneity of results may be partially due to the use of age groupings based on convenience, making comparisons across studies difficult. This study evaluated the independent effect of age on concussion incidence, severity, and recovery in student-athletes aged 12-18 years using cluster analysis to define groupings. Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) scores of 11,403 baseline tests and 4922 postinjury tests were used to calculate the incidence rates for adolescent student-athletes grouped into 3 age bands (12-13, 14-15, and 16-18 years of age) on the basis of clustering analysis. The recently created Severity Index was used to compare concussion severity between groups. Follow-up tests for subjects who sustained a concussion were used to evaluate recovery time. The chi-square test and 1-way ANOVA were used to compare differences in demographic characteristics and concussion incidence, severity, and recovery. Multivariable logistic and linear regressions were used to evaluate the independent effects of age on concussion incidence and severity, respectively. Multivariable Cox hazard regression was used to evaluate differences in recovery time. Further analyses were conducted to directly compare findings across studies on the basis of the age groupings used in prior studies. Multivariable regression analyses demonstrated that the 14- to 15-year-old age group had a significantly higher concussion incidence than both the 12- to 13-year-old (14- to 15-year-old group vs 12- to 13-year-old group, OR 1.57, 95% CI 1.16-2.17, p = 0.005) and 16- to 18-year-old (16- to 18-year-old group vs 14- to 15-year-old group, OR 0.79, 95% CI 0.69-0.91, p = 0.0008) age groups. There was no difference in incidence between the 12- to 13-year-old and 16- to 18-year-old groups (16- to 18-year group vs 12- to 13-year group, OR 1.26, 95% CI 0.93-1.72, p = 0.15). There were also no differences in concussion severity or recovery between any groups. This study found that concussion incidence was higher during mid-adolescence than early and late adolescence, suggesting a U-shaped relationship between age and concussion risk over the course of adolescence. Age had no independent effect on concussion severity or recovery in the 12- to 13-, 14- to 15-, and 16- to 18-year-old groups. Further analysis of the various age groups revealed that results may vary significantly with minor changes to groupings, which may explain the divergent results in the current literature on this topic. Thus, caution should be taken when interpreting the results of this and all similar studies, especially when groupings are based on convenience.

Air Pollution and Hospital Admission for Epilepsy in Kerman, Iran

Background: This study aimed to investigate the relation between air pollution and epilepsy admissions in Kerman, Iran. Methods: In this ecological study, the concentrations of ambient air pollutants and meteorological data were obtained from Kerman Environmental Protection Agency and Kerman Meteorology Organization, respectively. Additionally, epilepsy admission data were obtained from Kerman’s Shafa hospital epilepsy registry. Generalized additive models with lags up to 7 days were used to estimate rate ratios (RRs). Results: Within 2008 to 2020, 894 epilepsy admissions occurred in Kerman, 498 cases (55.7%) of whom were male. The strongest relations of epilepsy admission were observed in the over 59-year group for carbon monoxide (CO) in lag 0 (RR = 2.1455, 95% CI: 1.5823 - 2.9091), nitrogen dioxide (NO2) in lag 0 (RR = 1.0409, 95% CI: 1.0282 - 1.0537), and particulate matter under 2.5 microns (PM2.5) in lag 5 (RR = 1.0157, 95% CI: 1.0062 - 1.0252). There were also significant associations for particulate matter under 10 microns (PM10) in the under 18-year group in lag 2 (RR = 1.0064, 95% CI: 1.0029 - 1.0098), ozone in lag 0 (RR = 0.9671, 95% CI: 0.9581 - 0.9761), and sulfur dioxide in lag 5 (RR = 0.9937, 95% CI: 0.9891 - 0.9983). Conclusions: Exposure to CO, NO2, PM2.5, or PM10 air pollutants might be a risk factor for epilepsy admissions in Kerman. Epilepsy patients should better stay away from exposure to polluted air. Staying at home on polluted days or residing in areas with less air pollution might be an option.

Invasive Haemophilus influenzae disease among adults in Japan during 2014-2018.

We describe the epidemiology of invasive Haemophilus influenzae disease (IHD) among adults in Japan. Data for 200 adult IHD patients in 2014-2018 were analyzed. The capsular type of H. influenzae was determined by bacterial agglutination and polymerase chain reaction (PCR), and non-typeable Haemophilus influenzae (NTHi) was identified by PCR. The annual incidence of IHD (cases per 100,000 population) was 0.12 for age 15-64years and 0.88 for age ≥ 65years in 2018. The median age was 77years, and 73.5% were aged ≥ 65years. About one-fourth of patients were associated with immunocompromising condition. The major presentations were pneumonia, followed by bacteremia, meningitis and other than pneumonia or meningitis (other diseases). The case fatality rate (CFR) was 21.2% for all cases, and was significantly higher in the ≥ 65-year group (26.1%) than in the 15-64-year group (7.5%) (p = 0.013). The percentage of cases with pneumonia was significantly higher in the ≥ 65-year group than in the 15-64-year group (p < 0.001). The percentage of cases with bacteremia was significantly higher in the 15-64-year group than in the ≥ 65-year group (p = 0.027). Of 200 isolates, 190 (95.0%) were NTHi strains, and the other strains were encapsulated strains. 71 (35.5%) were resistant to ampicillin, but all were susceptible to ceftriaxone. The clinical presentations of adult IHD patients varied widely; about three-fourths of patients were age ≥ 65years and their CFR was high. Our findings support preventing strategies for IHD among older adults, including the development of NTHi vaccine.

Highly sensitive nested polymerase chain reaction to improve the detection of Leishmania species in clinical specimens.

Cutaneous leishmaniasis (CL) is one of the most neglected tropical diseases and an important health problem in many countries. It is an endemic disease in most regions of Iraq, while being non-endemic in the Kurdistan Region. The techniques frequently used for detection of CL are not very sensitive. Therefore, this study aimed to identify a sensitive method for diagnosis of CL in clinical samples. The present study was performed in December 2019 to December 2020 in Kalar General Hospital. Clinical samples were collected from 85 suspected CL cases. Sixty-four (75.29%), 71 (83.53%) and 84 (98.82%) cases were detected as positive for CL by microscopy, PCR, and nested PCR, respectively. Of the 84 nested PCR-confirmed CL patients, 46 (54.8%) were female and 38 (45.2%) were male. The most predominate rate of infection was in the 30-39-year age group (29.76%) and the lowest was in the ≥ 60-year group (3.57%). Forty (47.62%) patients had a single lesion. The statistical analysis showed significant differences between age groups and between the number of lesions. The sensitivities of microscopy, conventional PCR, and nested PCR were 80.77%, 86.6% and 100%, respectively, while all three methods showed 100% specificity. Furthermore, PCR-ITS1 followed by a simple restriction fragment length polymorphism (RFLP) analysis using HaeIII endonuclease indicated that Leishmania major was responsible for all CL infections in the study area.

Impact of ambient temperature on hospital admissions for respiratory diseases in suburban rural villages in northwest China.

Extreme temperature is strongly associated with human health, but few studies are available for the effects of extreme temperatures on respiratory disease (RD) in rural villages in Jiuquan, China over 2018-2019. In this study, we evaluate the effect of daily mean temperature on RD hospitalizations in suburban rural villages. A distribution lag non-linear model was constructed to analyze the relationship between the temperature and the daily risk of RD hospitalizations; and stratified analysis by sex and age group was performed. The effect of daily mean temperature on RD hospitalizations was non-linear and lagging. With a reference 25th percentile of temperature (-1.8 °C), exposure to extremely low temperature (-15.8 °C, 1st percentile), or moderate low temperature (-8.3 °C, 10th percentile) were associated with 1.396 (95% CI: 1.251, 1.558) and 1.216 (95% CI: 1.180, 1.253) increased risks of RD hospitalizations over lag 0-21 days. For RD morbidity, the effects of moderate high temperature (90th percentile of temperature, 22.5 °C) appeared at on the exposed day (lag 0), with the largest hot effect (RR 1.008, 95% CI 1.001, 1.020), while the effects of extremely high temperature (99th percentile of temperature, 27.0 °C) were insignificant. The effect of ambient temperature varied with gender and age. Both cold and high temperatures have more serious influence on males than females. In contrast, the elderly (age ≥ 65) seemed to be more sensitive in extremely low temperature (RR = 3.471; 95% CI, 2.183, 5.518; lag 0-21). The effect of moderate high temperature on the < 65 years group appeared for the first time at lag 0 (RR = 1.012; 95% CI, 1.001, 1.029). Both high temperature and low temperature increased the RD hospitalization risk; the harmful effect and duration of low temperature were greater than that of high temperature; the ≥ 65-year group and male were more sensitive to low temperature.

A retrospective analysis of the skull base fractures: demographic characteristics, causes and imaging findings

Background and objectives: Skull base fractures have high mortality and morbidity rates and constitute a significant medical issue. The aim of the present study was to review the demographic characteristics, common locations and causes of the skull base fractures retrospectively. Methods: This retrospective study was conducted on patients who attended the Intensive Care Unit/Radiology Clinic of Adiyaman University Training and Research Hospital between 2015 and 2018 and were found to have skull base fractures. The data were accessed via PACS system of the hospital database. Age, gender, cause of the trauma, type of the skull base fracture, imaging findings and outcome of the enrolled patients were analyzed. Results: Total 138 cases who met the study criteria were enrolled in the study. The causes of the skull base fracture were as follows: fall 52.2%, traffic accident 36.2%, pounding 3.6%, firearm injury 0.7%, sharp object injury 0.7%, and other causes 6.5%. There was a statistically significant (p&lt;0.001) difference in rate of skull base fracture caused by traffic accident between the ≤18-year group and 19-45 age group. The difference between the types of epidural hematoma was not significant in all age groups (p= 0.156); however, there was a statistically significant difference for gender (female vs. male 26.1%73.9%, p=0.025). Conclusion: Skull base fractures were more common in fall from height and traffic accidents. In order to reduce skull base fractures, it is recommended to take preventive precautions for falls from height and traffic accidents. IMC J Med Sci 2022; 16(2): 002.

Diagnosis and Course of Membranous Nephropathy in Adults: Comparison by Age Group

Introduction: There have been few studies comparing younger and older adults with membranous nephropathy. The objective of this study was to compare younger and older patients with membranous nephropathy, in terms of the clinical, etiological, remission, and survival data. Method: This was a retrospective study of patients with membranous nephropathy who underwent renal biopsy between 2009 and 2017. Results: We included 214 patients with membranous nephropathy. At diagnosis, 169 (79%) of those patients were <60 years of age and 45 (21%) were ≥60 years of age. There was a predominance of males in both groups. The degree of proteinuria and the prevalence of hematuria did not differ significantly between the groups. However, the median serum creatinine level was higher in the ≥60-year group as was the prevalence of hypertension. Of the patients evaluated, 36 (16.8%) had secondary membranous nephropathy. Although the proportions of infectious and autoimmune causes were comparable between the two groups, neoplastic etiologies were more common in the ≥60-year group. A total of 86 in the <60-year group and 25 in the ≥60-year group were followed long term, and partial or complete remission was achieved in 68.5% and 68.0% of the younger and older patients, respectively. However, whom progressed to requiring dialysis eight (9.3%) were in the <60-year group patients and eight (32.0%) of the ≥60-year group patients (p = 0.0045). Conclusion: Despite having worse renal function at diagnosis, older patients with membranous nephropathy appear to have remission rates comparable to those of younger patients with the disease, which demonstrates the benefits of seeking diagnosis and treatment.

Trends of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody prevalence in selected regions across Ghana

Background: We set out to estimate the community-level exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Ghana. Methods: Phased seroprevalence studies of 2729 participants at selected locations across Ghana were conducted. Phase I (August 2020) sampled 1305 individuals at major markets/lorry stations, shopping malls, hospitals and research institutions involved in coronavirus disease 2019 (COVID-19) work. The study utilized a lateral flow rapid diagnostic test (RDT) which detected IgM and IgG antibodies against SARS-CoV-2 nucleocapsid protein. Results: During Phase I, 252/1305 (19%) tested positive for IgM or IgG or both. Exposure was significantly higher at markets/lorry stations (26.9%) compared to malls (9.4%), with 41–60-year group demonstrating highest seropositivity (27.2%). Exposure was higher in participants with no formal education (26.2%) than those with tertiary education (13.1%); and higher in informally employed workers (24.0%) than those in the formal sector (15.0%). Results from phases II and III, in October and December 2020 respectively, implied either reduced transmissions or loss of antibody expression in some participants. The Upper East region showed the lowest seropositivity (2%). Phase IV, in February 2021, showed doubled seropositivity in the upper income bracket (26.2%) since August 2020, reflective of Ghana’s second wave of symptomatic COVID-19 cases. This suggested that high transmission rates had overcome the initial socioeconomic stratification of exposure risk. Reflective of second wave hospitalisation trends, the 21-40 age group demonstrated modal seropositivity (24.9) in Phase IV whilst 40-60 years and 60+ previously demonstrated highest prevalence. Conclusions: Overall, the data indicates higher COVID-19 seroprevalence than officially acknowledged, likely implying a considerably lower-case fatality rate than the current national figure of 0.84%. The data also suggests that COVID-19 is predominantly asymptomatic COVID-19 in Ghana. The observed trends mimic clinical trends of infection and imply that the methodology used was appropriate.

Short-term outcomes in older patients with peritoneal malignancy treated with cytoreductive surgery and HIPEC: Experience with 245 patients from a national centre

BackgroundCytoreductive Surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly accepted as the optimal management of selected patients with peritoneal malignancy. There is limited published evidence on outcomes in older patients treated by this complex therapeutic strategy. MethodsA retrospective review of a prospective database of all patients who underwent CRS with HIPEC in a single institution over seven years. A comparative analysis of outcomes in patients under 65 undergoing CRS and HIPEC with patients ≥65 years was performed. The key endpoints were morbidity, mortality, reintervention rate and length of stay in the high dependency/intensive care (HDU/ICU) units. ResultsOverall, 245 patients underwent CRS and HIPEC during the study period, with 76/245 (31%) ≥65 years at the time of intervention. Tumour burden measured by the peritoneal carcinomatosis index (PCI) score was a median of 11 for both groups. Median length of hospital stay in the ≥65-year-old group was 14.5 days versus 13 days in the <65-year-old group (∗p = 0.01). Patients aged ≥65-years spent a median of one more day in the critical care unit ∗(p = 0.001). Significant morbidity (Clavien-Dindo ≥ Grade IIIa) was higher in the ≥65-year than the <65-year group (18.4% versus 11.2%). There were no perioperative deaths in the ≥65-year group. ConclusionThis study demonstrates higher perioperative major morbidity in ≥65-year group, but with low mortality in patients undergoing CRS/HIPEC for disseminated intraperitoneal malignancy. This increased morbidity does not translate into higher rates of re-interventions and highlights the importance of optimal patient selection.

The Mobile Health Readiness of People Receiving In-Center Hemodialysis and Home Dialysis.

Mobile health is the health care use of mobile devices, such as smartphones. Mobile health readiness is a prerequisite to successful implementation of mobile health programs. The aim of this study was to examine the status and correlates of mobile health readiness among individuals on dialysis. A cross-sectional 30-item questionnaire guided by the Khatun mobile health readiness conceptual model was distributed to individuals on dialysis from 21 in-center hemodialysis facilities and 14 home dialysis centers. The survey assessed the availability of devices and the internet, proficiency, and interest in using mobile health. In total, 949 patients (632 hemodialysis and 317 home dialysis) completed the survey. Of those, 81% owned smartphones or other internet-capable devices, and 72% reported using the internet. The majority (70%) reported intermediate or advanced mobile health proficiency. The main reasons for using mobile health were appointments (56%), communication with health care personnel (56%), and laboratory results (55%). The main reported concerns with mobile health were privacy and security (18%). Mobile health proficiency was lower in older patients: compared with the 45- to 60-years group, respondents in age groups <45, 61-70, and >70 years had adjusted odds ratios of 5.04 (95% confidence interval, 2.23 to 11.38), 0.39 (95% confidence interval, 0.24 to 0.62), and 0.22 (95% confidence interval, 0.14 to 0.35), respectively. Proficiency was lower in participants with Hispanic/Latinx ethnicity (adjusted odds ratio, 0.49; 95% confidence interval, 0.31 to 0.75) and with less than college education (adjusted odds ratio for "below high school," 0.09; 95% confidence interval, 0.05 to 0.16 and adjusted odds ratio for "high school only," 0.26; 95% confidence interval, 0.18 to 0.39). Employment was associated with higher proficiency (adjusted odds ratio, 2.26; 95% confidence interval, 1.18 to 4.32). Although home dialysis was associated with higher proficiency in the unadjusted analyses, we did not observe this association after adjustment for other factors. The majority of patients on dialysis surveyed were ready for, and proficient in, mobile health. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER DIALYSIS MHEALTH SURVEY,: NCT04177277.
