Tracing Digital Therapeutics Research Across Medical Specialties: Evidence from ClinicalTrials.gov.

Digital therapeutics (DTx), evidence-based software interventions for preventing, managing, or treating medical disorders, have rapidly evolved with healthcare's shift toward online, patient-centric solutions. This study scrutinizes DTx clinical trials from 2005 to 2022, analyzing their growth, funding, underlying medical specialties, and other R&D characteristics, using ClinicalTrials.gov data. Our analysis includes trials categorized via the ICD-11 system, covering active, recruiting, or completed studies and considering trials listing multiple conditions. In analyzing 5,889 registered DTx trials, we document a more than five-fold increase in such trials since 2011, and a compound annual growth rate of 22.82% since 2005. While most trials were single-center, the median number of study subjects increased in recent years, driven by larger interventional trials. The key disciplines driving this growth were psychiatry, neurology, oncology, and endocrinology. Mental health dominated DTx trials in recent years, led by neurocognitive disorders, substance abuse disorders, and mood disorders. Industry funding varied across disciplines and was particularly high in visual system diseases and dermatology. DTx trials have surged since 2005, accelerated by recent growth in mental health trials. These trends mirror developments toward remote healthcare delivery, amplified by digital health investments during the COVID-19 pandemic. Growing numbers of participants in DTx trials point to increased demand for more robust trials. However, because most trials are single-center and country-specific, more international cooperation and harmonized evaluation standards will be essential for DTx trials to become more efficient and provide validation across countries, health systems, and groups of individuals.

Medical Disorders in Pregnancy Among Inpatients at a Tertiary Level Hospital of Peshawar (Khyber Pakhtunkhwa)

OBJECTIVES This study aimed to determine the prevalence, type, and demographic makeup of pregnancy-related medical conditions among patients receiving treatment in a tertiary care facility. METHODOLOGY The Monocentric retrospective impact study was conducted in the Department of Obstetrics and Gynaecology of MTI, Hayatabad Medical Complex Peshawar, from January to December 2022. Case records of all pregnant women (n=1811) with previous or recently developed medical conditions treated during the study period were collected from the records / medical registers, and all the information was recorded in a pre-structured proforma. All women with previous or recently developed medical conditions treated during the study were included. All pregnant women without any medical conditions were excluded. Data was analyzed using simple statistical measures, and the results were presented as frequency percentages. Prior approval from the institution’s ethical committee was obtained to conduct the study. vRESULTSAmong 6327 antenatal admissions, 1811 (28.62%) women had medical disorders. The most common medical disorder was PIH, reported in 384 (21.20%) of the females, followed by RH incompatibility and Gestational Diabetes Mellitus (GDM) seen in 235 (12.98%) and 205 (11.32%) females, respectively. Other notable medical conditions include UTI in 170 (9.39%), Chronic HTN in 134 (7.40%), iron deficiency anemia in 122 (6.74%), and pre-eclampsia in 100 (5.52%) of women. CONCLUSION Pre-existing medical conditions in pregnancy are not uncommon. Early recognition of acute illness and treatment of chronic conditions in pregnancy is of clear benefit and needs to be managed to arrest any adversaries to the mother and fetus.

Comparison of Placental Location on Ultrasound in Preeclampsia and Normotensive Pregnancy in Third Trimester.

Hypertensive disorders in pregnancy account for 15%-20% maternal and 20%-25% perinatal mortality. There is interest in predicting preeclampsia (PE) early in pregnancy to reduce PE and its subsequent complications. There is no cheap and easily available, reliable predictor for PE. Some studies have shown that the lateral location of placenta is associated with adverse pregnancy outcomes due to PE. The lateral placenta is yet to be proven as a strong predictor of PE to initiate preventive measures. Placental localization can be easily done on routine ultrasonography during pregnancy. In the light of these observations, a prospective study was done to study any association between PE and placental location by ultrasound in third trimester. Research Question: Is there any association between placental location on ultrasound and preeclampsia in third trimester? The objective is to study association between location of placenta and preeclampsia and compare placental location in normotensive pregnancies with that in PE in third trimester. A prospective comparative, case-control, observational study was conducted in the Department of Obstetrics and Gynecology at North DMC Medical College and Hindu Rao Hospital, Delhi, India, from August 2019 to April 2020. The study population included 200 pregnant women with singleton pregnancy in third trimester, without any medical disorders such as diabetes mellitus, hypertension, renal disease, cardiac disease, and coagulation disorder or smoking. One hundred women had preeclampsia and 100 were normotensive controls. Ultrasound was done after filling F form as per the Government of India guidelines to rule out sex determination, and placenta was localized by ultrasound. Placenta was classified as central when it was equally distributed between the right and left sides of the uterus irrespective of anterior, posterior, or fundal position and lateral when 75% or more of the placental mass was on one side of the midline. Placental location was compared in hypertensive and normotensive pregnancies. Out of the total 200 women, 152 (76%) had central and 48 (24%) had lateral placenta. Ninety-two percent of controls and 60% of cases had central placenta. Forty percent of cases and only 8% normotensive women had lateral placenta. Lateral placenta was five times more frequent in presence of PE as compared to normotensive controls. Out of 152 women with central placenta, 92 (60.5%) women were normotensive but with lateral placenta, only 8 (16.7%) had normal blood pressure. PE was present in 83% of women with lateral placenta and in only 39.47% with central placenta. This difference was statistically significant as P < 0.0001 as per Chi-square test. This reflects a significant association between lateral position of placenta and occurrence of PE. As per odds ratio (0.1304) patients without lateral placenta had 90% protection against preeclampsia. Central placenta is more common than lateral placenta. Lateral placenta is seen five times more frequently among hypertensive women and this difference is statistically significant. The absence of lateral placenta provides 90% protection against PE but the severity of PE was not affected by placental location..

Asymptomatic Bacteriuria in Pregnancy Causes and Incidence

OBJECTIVES This study aims to provide an understanding of asymptomatic bacteriuria in pregnancy by examining its frequency, causative agent, and potential strategies for detection and management. METHODOLOGY A cross-sectional study was conducted in the Department of Obstetrics and Gynecology, PGMI Hayatabad Medical Complex, Peshawar, from July to December 2022. The study included 117 antenatal patients with varying gestational periods attending the OPD. Patients with a history of antibiotic therapy, urinary frequency and dysuria, vaginal discharge, renal tract anomalies, and medical disorders were excluded. Demographic details were recorded, and urine samples were collected and cultured. Data was analyzed using SPSS version 22. RESULTSThe incidence of asymptomatic bacteriuria was 25.5%, among 117 women, with E. coli (53.3%) the most common pathogen responsible for the infection, followed by Klebsiella (36.7%) and staphylococcus (10%).CONCLUSIONBacteriuria without causing any symptoms is quite common in pregnancy. Simple measures like screening early in pregnancy can timely detect positive cases and with targeted treatment, both maternal and neonatal morbidity can be curtailed.

Can telehealth expansion boost health care utilization specifically for patients with substance use disorders relative to patients with other types of chronic disease?

Patients with substance use disorders (SUDs) exhibit low healthcare utilization despite high risk of poor outcomes. Telehealth expansion may boost utilization, but it is unclear whether telehealth can increase utilization for patients with SUDs beyond that expected for other chronic diseases amenable to remote treatment, like type 2 diabetes. This information is needed by health systems striving to improve SUD outcomes, specifically. This study compared the impact of telehealth expansion during the COVID-19 public health emergency (PHE) on utilization for patients with SUDs and diabetes. Using Wisconsin Medicaid administrative, enrollment and claims data 12/1/2018-12/31/2020, this cohort study included nonpregnant, nondisabled adults 19-64 years with SUDs (N = 17,336) or diabetes (N = 8,499). Outcomes included having a primary care visit in the week (any, and telehealth) for any diagnosis, or a SUD or diabetes diagnosis; and the weekly fraction of visits completed by telehealth. Logistic and fractional regression examined outcomes pre- and post-PHE. Covariates included age, sex, race, ethnicity, income, geography, and comorbid medical and psychotic disorders. Post-PHE, patients with SUDs exhibited greater likelihood of telehealth utilization (percentage point difference (PPD) per person-week: 0.2; 95% CI: 0.001-0.003; p<0.001) and greater fractional telehealth use (PPD: 1.8; 95%CI: 0.002-0.033; p = 0.025) than patients with diabetes despite a larger overall drop in visits (PPD: -0.5; 95%CI: -0.007- -0.003; p<0.001). Following telehealth expansion, patients with SUDs exhibited greater likelihood of telehealth utilization than patients with diabetes. This advantage lessened the substantial PHE-induced healthcare disruption experienced by patients with SUDs. Telehealth may boost utilization for patients with SUDs.

Sarcoidosis in pregnancy

Key content: Sarcoidosis is an uncommon multi‐system disorder characterised by the presence of non‐caseating granulomas. It has a peak incidence between the ages of 20–40 years old. The pathogenesis of sarcoidosis is uncertain; however, it is known to be associated with an exaggerated T helper 1 (TH1) immune response leading to systemic inflammation and granuloma formation. Suppression in TH1 responses in pregnancy leads to disease remission in the majority of pregnancies. Nevertheless, the potential for decompensation in a subgroup remains, and consideration should be given to the pre‐pregnancy state. Sarcoidosis is associated with increased risk of maternal‐fetal morbidity, including growth restriction and pre‐eclampsia. Clinical management should focus on medication optimisation and mitigation of this increased risk. Learning objectives: To understand the clinical features, pathogenesis and diagnosis of sarcoidosis. To understand the effect of pregnancy on sarcoidosis. To understand the effect of sarcoidosis on pregnancy and the related obstetric outcomes. To understand the management of sarcoidosis in pregnancy. Ethical issues: There can be difficulties in appropriate management of medical disorders, such as sarcoidosis, with a limited obstetric evidence base. There are challenges in decision‐making regarding continuation of pregnancy in severe disease with an uncertain evidence base.

Level of Awareness Regarding Interventional Radiology Among Medical Students at Northern Border University in Arar, Saudi Arabia.

Introduction Interventional radiology (IR) is a highly specialized field of radiology that employs advanced imaging techniques like MRIs, CT scans, X-rays, and ultrasounds to detect and treat a variety of medical disorders. By using minimally invasive procedures, interventional radiologists can access the body's internal organs and tissues with minimal discomfort and reduced risks compared to traditional surgical techniques. Some common IR procedures include angioplasty, embolization, biopsy, and stent placement, among others. Overall, IR is an innovative and effective approach to medical care that offers numerous benefits to patients. As this specialty expands, there is a huge demand for increasing staff. However, due to a lack of awareness, this increased demand could not be fulfilled. Objective The objective is to assess medical students' knowledge regarding IR and compare this knowledge between male and female students. Materials and methods This cross-sectional study was carried out at Northern Border University's College of Medicine in Arar, Saudi Arabia. The study aimed to assess the medical students' knowledge of IR. All students enrolled in the clinical years at Northern Border University were included in the study, and a self-administered online questionnaire was used to collect data. The minimum sample size required was 169. Appropriate statistical analysis was applied to the collected data, and a p-value of less than 0.05 was considered significant. Results One hundred and seventy-two participants in all who met the inclusion criteria answered the study's questionnaire. The fourth-year students represented the highest percentage of the sample, with 65 participants (37.8%), followed by 54 (31.4%) fifth-year students and 53 (30.8%) sixth-year students. The study found that 66 participants (38.4%)rated their knowledge of IR as adequate, while only 8 (4.7%) considered it excellent. The participants' self-rated knowledge of IR did not significantly differ across male and female groups. Conclusion The study's findings suggest that medical students have limited knowledge of IR and that there is no discernible difference in the knowledge and interest of males and females in this subject. Further research and targeted educational interventions may be necessary to improve the medical students' overall knowledge and interest in IR.

Suicidal behavior in combat veterans with mood disorders

AbstractIntroduction. Military conflicts are ubiquitous. There are many combat veterans around the world. The combat environment is characterized by violence, physical strains, separation from loved ones, and other hardships. Mood disorders and suicidality in combat veterans are a large and important issue.ObjectivesTo discuss the pathophysiology and prevention of suicidal behavior in combat veterans with mood disordersMethods A review of the literature on suicidal behavior in combat veterans with mood disorders including own publications.ResultsCombat deployment may lead to multiple emotional, cognitive, psychosomatic symptoms, mood disorders, suicidal ideation and behavior. Pre-deployment, deployment and post-deployment adversities may increase risk of mood disorders and suicide in combat veterans. The act of killing in combat is a stressor which may raise suicide risk. Combat-related injuries are associated with significantly increased depression and suicide risk. Post-deployment difficulties of reintegrating into civilian life may lead to depression and suicidality. Studies suggest that suicidal behavior in combat veterans may have a neurobiological basis. Prevention of mood disorders and suicide among combat veterans should include pre-deployment screening to exclude individuals with psychiatric disorders; psychological support and prevention of harassment and/or abuse during deployment; psychosocial support after deployment; diagnosing and treating psychiatric and medical disorders including neurological disorders; frequent depression and suicide screening; education of mental and non-mental health clinicians, war veterans, their families and friends regarding signs/symptoms of mood disorders and suicidality; and restriction of access to lethal means.ConclusionCombat veterans are a unique population. They are frequently exposed to psychological, physical, and biological factors which are unusual for civilians or non-combat military veterans. We need to study the specific psychobiology of combat veterans to understand how to develop effective depression and suicide prevention interventions for this population.Disclosure of InterestNone Declared

Fetal Outcome among Women with Postdate Pregnancy

OBJECTIVE: The study aimed to determine the mode of delivery and fetal outcome among women with postdated pregnancies. METHODOLOGY: This cross-sectional study was conducted from July to December 2020 in the Department of Gynecology, Hayatabad Medical Complex, Peshawar. A total of 287 women with postdated pregnancies (beyond 41 weeks) were selected through a convenient sampling technique for the study and followed to detect expected fetal outcomes. All women of age 20-45 with no signs of labor onset and cepahlic presentation of singleton pregnancy were included, while women with retained placenta detected by ultrasound, women with a medical disorder like coagulopathies (Haemophilia, Von Willebrand disease, Thrombocytopenia, DIC, Protein S deficiency, Protein C deficiency) detected by the specific investigation were excluded from the study. Data was analyzed using SPSS version 20. RESULTS: The mean age of the sample was 30.5 years, with a standard deviation of 6.1 years. The mean parity of the sample was 2.1±1.5. The mean BMI of the sample was 26.1±3.8kg/m2. On follow-up, fetal distress in 16%, macrosomia in 18.5%, birth asphyxia in 18.1%, meconium aspiration in 8.4% and NICU admission in 9.1%. None of the neonates died in this study. CONCLUSION: Postdated pregnancy carries a high risk of fetal distress, macrosomia and birth asphyxia. We recommend more large-scale surveys as well as trials to determine the efficacy of induction before pregnancy enters the postdate period and reduce the morbidity and mortality due to postdate pregnancies. KEYWORDS: Postdate Pregnancy, Meconium Aspiration, Birth Asphyxia, Fetal Distress, Intrauterine Growth Restriction, Macrosomia

Pregnant Women’s Experiences of Sexual Activity During Pregnancy: A Qualitative Study

Background: Pregnancy is a sensitive time in women’s lives, as they experience numerous physical, psychological, and behavioral changes that can affect their sexual and marital relations. Due to the significance of this topic, the present study aimed to examine pregnant women’s experiences of sexual activity during pregnancy. Methods: The participants in this qualitative content analysis study were 23 pregnant women who visited hospitals in Babolsar, Iran (2019-2020) and were selected using purposive sampling. Following in-depth interviews, a semi-structured questionnaire guide was used to collect qualitative data. Data were analyzed using the conventional content analysis method proposed by Graneheim and Lundman. The MAXQDA 10 software was utilized for qualitative data analysis. Results: In the present study, pregnant women ranged in age from 19 to 35 years. The analysis of pregnant women’s experiences of sexual activity during pregnancy led to the identification of four categories including sexual changes perceived during pregnancy, strategies for coping with sexual changes during pregnancy, sexual changes leading to the couple’s development, and factors influencing sexual activity during pregnancy. Conclusion: During pregnancy, women observe various sexual changes in themselves and their partners, influenced by gestational age, medical disorders, physical changes, psychological and emotional factors, and underlying factors. Accordingly, it is recommended that couples be educated on sexual health during pregnancy which emphasizes the need for further research in this area.

Diving Medicine: An Exciting Journey Through Time and Future Prospects.

Humans, led by their eternal wish to explore the unknown, have always wanted to perfect their diving skills and conquer the sea world. The adverse conditions experienced by divers brought about medical problems and a new field of medicine. Diving medicine serves the identification, treatment, and precautions against illnesses that are related to diving activities. While the development of diving equipment is advancing, divers have had the chance to reach greater depths for a longer time. Along with this success, a novel medical condition under the term 'decompression illness' (DCI) was introduced. Although the history of hyperbaric medicine is very long, progress in the field of mechanics has offered great contributions to the management of the disease. The first attempt at DCI guidelines was made by the US Navy in 1944-1945 and resulted in the creation of hyperbaric treatment tables. These tools received international recognition, offering a major advance. Hyperbaric-Diving Medicine holds an important place in modern medical science nowadays with indications for various diseases. At the same time, there is great scientific interest and a lot of research in the use of hyperbaric oxygen for several medical disorders, demonstrating great potential.

Composite Conductive Carbon-Polymer Paints as a Replacement for the “Faraday Cage”

We have developed composite paint based on graphite, carbon black and some other not expensive components, which can be used as a clay court for sustainable buildings and electronic devices. This paint can reduce sufficiently the problem, which is related to the effects of electromagnetic radiation (EMR) on human health. Cellular and radiotelephones, as well as their broadcast antennas, especially which use of the 5G, 6G communication system, may pose a high risk of cancer, reproductive disorders, memory, cellular stress, neurological and mental disorders. The medical disorders are already often experienced by servicemen working at radar stations, observation posts and other similar facilities associated with high-frequency EMR. The effect of EMR is especially dangerous for children of preschool and school age, so, it is necessary to use similar paints first of all for such buildings.

It is also necessary to note the significant impact of EMR on electronic equipment. First of all, this is a well-known problem of providing the so-called "electronic compatibility", when simultaneously operating different electronic equipment (e.g., thermal imager and radio transmitter) interfere with each other. A number of scientific developments have been implemented and work is underway under the NATO SfS international grant in this area.

CLIPSyntel: CLIP and LLM Synergy for Multimodal Question Summarization in Healthcare

In the era of modern healthcare, swiftly generating medical question summaries is crucial for informed and timely patient care. Despite the increasing complexity and volume of medical data, existing studies have focused solely on text-based summarization, neglecting the integration of visual information. Recognizing the untapped potential of combining textual queries with visual representations of medical conditions, we introduce the Multimodal Medical Question Summarization (MMQS) Dataset. This dataset, a major contribution of our work, pairs medical queries with visual aids, facilitating a richer and more nuanced understanding of patient needs. We also propose a framework, utilizing the power of Contrastive Language Image Pretraining(CLIP) and Large Language Models(LLMs), consisting of four modules that identify medical disorders, generate relevant context, filter medical concepts, and craft visually aware summaries. Our comprehensive framework harnesses the power of CLIP, a multimodal foundation model, and various general-purpose LLMs, comprising four main modules: the medical disorder identification module, the relevant context generation module, the context filtration module for distilling relevant medical concepts and knowledge, and finally, a general-purpose LLM to generate visually aware medical question summaries. Leveraging our MMQS dataset, we showcase how visual cues from images enhance the generation of medically nuanced summaries. This multimodal approach not only enhances the decision-making process in healthcare but also fosters a more nuanced understanding of patient queries, laying the groundwork for future research in personalized and responsive medical care.

Misdiagnosis of functional neurological symptom disorders in paediatrics: Narrative review and relevant case report.

Functional neurological symptom disorders (FNSD) pose a common challenge in clinical practice, particularly in pediatric cases where the clinical phenotypes can be intricate and easily confused with structural disturbances. The frequent coexistence of FNSDs with other medical disorders often results in misdiagnosis. In this review, we highlight the distinctions between FNSD and various psychiatric and neurological conditions. Contrary to the misconception that FNSD is a diagnosis of exclusion, we underscore its nature as a diagnosis of inclusion, contingent upon recognizing specific clinical features. However, our focus is on a critical learning point illustrated by the case of a 14-year-old male initially diagnosed with FNSD, but subsequently found to have a rare primary monogenic movement disorder (paroxysmal kinesigenic dyskinesia, PKD). The crucial takeaway from this case is the importance of avoiding an FNSD diagnosis based solely on psychiatric comorbidity and suppressible symptoms. Instead, clinicians should diligently assess for specific features indicative of FNSD, which were absent in this case. This emphasizes the importance of making a diagnosis of inclusion. Extended follow-up and clinical-oriented genetic testing might help identify comorbidities, prevent misdiagnosis, and guide interventions in complex cases, which cannot be simply classified as "functional" solely because other conditions can be excluded.

Second twin outcome at birth: retrospective analysis in a single tertiary centre in Malaysia.

To investigate factors associated with outcome of second twin during labour. The study was a retrospective cohort study in a single tertiary centre in Malaysia from 2014 until 2018 involving all twin pregnancies delivered at or more than 24weeks of gestation. Total of 409 twin pregnancies were included. Dichorionic twin comprises of 54.5 % (n=223) and 45.5 % (n=186) are monochorionic. Women with dichorionic pregnancies are significantly older (p<0.001), have more pre-existing medical disorders (p=0.011) and fetal structural anomalies (p=0.009). Monochorionic pregnancies are significantly more amongst Malay (p=0.01) and conceived spontaneously (p<0.001). There are significantly more fetuses both in cephalic presentation (p=0.026), birthweight discrepancy more than 20 % (p=0.038) and shorter mean inter-twin delivery duration (p=0.048) in monochorionic pregnancies. Second twin delivered with Apgar score <7 is significantly more in dichorionic pregnancies (p=0.006). The second twin is associated with lower birthweight, small for gestational age and arterial cord pH<7.25. Within the group of women who delivered both fetuses vaginally, there was significantly more second twins with intertwin delivery duration less than 30 min who were delivered vaginally without instrumentation (p=0.018). There was significantly more second twin with intertwin delivery duration of 30 min and more with arterial cord pH<7.25 (p=0.045). Those who delivered spontaneously had inter-twin delivery duration within 15-29 min. The outcome of second twin is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth. The neonatal outcome for the second twin at birth is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth in a cohort managed with non-active management of the second twin in Malaysia.

Sleep alterations as a function of 88 health indicators

BackgroundAlterations in sleep have been described in multiple health conditions and as a function of several medication effects. However, evidence generally stems from small univariate studies. Here, we apply a large-sample, data-driven approach to investigate patterns between in sleep macrostructure, quantitative sleep EEG, and health.MethodsWe use data from the MrOS Sleep Study, containing polysomnography and health data from a large sample (N = 3086) of elderly American men to establish associations between sleep macrostructure, the spectral composition of the electroencephalogram, 38 medical disorders, 2 health behaviors, and the use of 48 medications.ResultsOf sleep macrostructure variables, increased REM latency and reduced REM duration were the most common findings across health indicators, along with increased sleep latency and reduced sleep efficiency. We found that the majority of health indicators were not associated with objective EEG power spectral density (PSD) alterations. Associations with the rest were highly stereotypical, with two principal components accounting for 85–95% of the PSD-health association. PC1 consists of a decrease of slow and an increase of fast PSD components, mainly in NREM. This pattern was most strongly associated with depression/SSRI medication use and age-related disorders. PC2 consists of changes in mid-frequency activity. Increased mid-frequency activity was associated with benzodiazepine use, while decreases were associated with cardiovascular problems and associated medications, in line with a recently proposed hypothesis of immune-mediated circadian demodulation in these disorders. Specific increases in sleep spindle frequency activity were associated with taking benzodiazepines and zolpidem. Sensitivity analyses supported the presence of both disorder and medication effects.ConclusionsSleep alterations are present in various health conditions.

Clinical features of atypical presentations of mucocutaneous herpes simplex virus infection observed in immunosuppressed individuals. Part I: herpetic geometric glossitis.

Herpetic geometric glossitis is a unique morphologic variant of HSV (herpes simplex virus) type 1 infection on the dorsum of the tongue that presents as an extremely painful linear central lingual fissure with a branched pattern. in the center of the tongue; there is a branched pattern of fissures that extend bilaterally from the central linear fissure. Herpetic geometric glossitis has been reported in 11 patients; 8 of these individuals were immunocompromised. Medical conditions and immunosuppressive medication treatment (7 patients) or only medical disorders (3 patients) or neither (1 patient) were present. HSV type 1 infection was diagnosed by viral culture in (7 patients), Tzanck preparation (2 patients) or clinically (2 patients). Mucocutaneous HSV infection at non-lingual locations--including the lips, labial mucosa, face and chest--were observed in 5 patients. All patients' symptoms and lesions responded to treatment with oral antiviral therapy: acyclovir (9 patients), famciclovir (1 patient) or valacyclovir (1 patient). The lingual pain and dorsal tongue fissures completely resolved completely within two to 14 days. In summary, herpetic geometric glossitis is a unique HSV type 1 infection, usually in immunocompromised patients, that occurs on the dorsal tongue and responds completely after treatment with orally administered antiviral therapy.

Characteristics of Users of a Digital Hypnotherapy Intervention for Hot Flashes: Retrospective Study.

Hot flashes are associated with a lower quality of life and sleep disturbances. Given the many consequences of hot flashes, it is important to find treatments to reduce them. Hypnotherapy, the use of hypnosis for a medical disorder or concern, has been shown in clinical trials to be effective in reducing hot flashes, but it is not routinely used in clinical practice. One solution to close this implementation gap is to administer hypnotherapy for hot flashes via a smartphone app. Evia is a smartphone app that delivers hypnotherapy for hot flashes. Evia has made hypnotherapy more widely accessible for women who are experiencing hot flashes; however, the app has yet to undergo empirical testing. Additionally, research on user characteristics is lacking. This study aims to (1) determine the average age, stage of menopause, and length of menopause symptoms for users of the Evia app; (2) determine the characteristics of hot flashes and night sweats for users of the Evia app; (3) determine the self-reported sleep quality of users of the Evia app; (4) determine the self-reported mental health of users of the Evia app; and (5) determine the relationship between hot flash frequency and anxiety and depression for users of the Evia app. This study analyzed data collected from participants who have downloaded the Evia app. Data were collected at 1 time point from a self-report questionnaire that assessed the demographic and clinical characteristics of users. The questionnaire was given to users when they downloaded the Evia app. Users of the Evia app fill out a questionnaire upon enrolling in the program and prior to beginning the intervention. This included 9764 users. Results showed that the mean age of users was 49.31 years. A total of 41.6% (1942/4665) of users reported experiencing 5 or more hot flashes per day, while 51.2% (1473/2877) of users reported having difficulty falling asleep each night and 47.7% (1253/2626) of users reported their sleep quality to be terrible. In addition, 38.4% (1104/2877) of users reported that they often feel anxious or depressed. There was a small, significant, and negative correlation between hot flash frequency and self-report frequency of anxiety and depression (r=-0.09). This study showed that the average age of app users is in line with the median age of natural menopause. A large percentage of users reported experiencing 5 or more hot flashes per day, reported difficulties with sleep, and reported experiencing depression and anxiety. These findings are in line with previous studies that assessed hot flash frequency and the consequences of hot flashes. This was the first study to report on the characteristics of users of the Evia app. Results will be used to optimize the hypnotherapy program delivered via the Evia app.

Breast composition during and after puberty: the Chilean Growth and Obesity Cohort Study

BackgroundBreast density (BD) is a strong risk factor for breast cancer. Little is known about how BD develops during puberty. Understanding BD trajectories during puberty and its determinants could be crucial for promoting preventive actions against breast cancer (BC) at early ages. The objective of this research is to characterize % fibroglandular volume (%FGV), absolute fibroglandular volume (AFGV), and breast volume (BV) at different breast Tanner stages until 4-year post menarche in a Latino cohort and to assess determinants of high %FGV and AFGV during puberty and in a fully mature breast.MethodsThis is a longitudinal follow-up of 509 girls from low-middle socioeconomic status of the Southeast area of Santiago, recruited at a mean age of 3.5 years. The inclusion criteria were singleton birth born, birthweight between 2500 and 4500 g with no medical or mental disorder. A trained dietitian measured weight and height since 3.5 years old and sexual maturation from 8 years old (breast Tanner stages and age at menarche onset). Using standardized methods, BD was measured using dual-energy X-ray absorptiometry (DXA) in various developmental periods (breast Tanner stage B1 until 4 years after menarche onset).ResultsIn the 509 girls, we collected 1,442 breast DXA scans; the mean age at Tanner B4 was 11.3 years. %FGV increased across breast Tanner stages and peaked 250 days after menarche. AFGV and BV peaked 2 years after menarche onset. Girls in the highest quartiles of %FGV, AFGV, and BV at Tanner B4 and B5 before menarche onset had the highest values thereafter until 4 years after menarche onset. The most important determinants of %FGV and AFGV variability were BMI z-score (R2 = 44%) and time since menarche (R2 = 42%), respectively.ConclusionWe characterize the breast development during puberty, a critical window of susceptibility. Although the onset of menarche is a key milestone for breast development, we observed that girls in the highest quartiles of %FGV and AFGV tracked in that group afterwards. Following these participants in adulthood would be of interest to understand the changes in breast composition during this period and its potential link with BC risk.

Depression and cognition are associated with lipid dysregulation in both a multigenerational study of depression and the National Health and Nutrition Examination Survey

Chronic dysregulation of peripheral lipids has been found to be associated with depression and cognition, but their interaction has not been investigated. Growing evidence has highlighted the association between peripheral lipoprotein levels with depression and cognition with inconsistent results. We assessed the association between peripheral lipids, depression, and cognition while evaluating their potential interactions using robust clinically relevant predictors such as lipoprotein levels and chronic medical disorders that dysregulate lipoproteins. We report an association between peripheral lipids, depression, and cognition, suggesting a common underlying biological mechanism driven by lipid dysregulation in two independent studies. Analysis of a longitudinal study of a cohort at high or low familial risk for major depressive disorder (MDD) (n = 526) found metabolic diseases, including diabetes, hypertension, and other cardiovascular diseases, were associated with MDD and cognitive outcomes. Investigating a cross-sectional population survey of adults in the National Health and Nutrition Examination Survey 2011–2014 (NHANES) (n = 2377), depression was found to be associated with high density lipoprotein (HDL) and cognitive assessments. In the familial risk study, medical conditions were found to be associated with chronic lipid dysregulation and were significantly associated with MDD using the structural equation model. A positive association between chronic lipid dysregulation and cognitive scores was found in an exploratory analysis of the familial risk study. In a complementary study, analysis of NHANES revealed a positive association of HDL levels with cognition. Further analysis of the NHANES cohort indicated that depression status mediated the interaction between HDL levels and cognitive tests. Importantly, the protective effect of HDL on cognition was absent in those with depressive symptoms, which may ultimately result in worse outcomes leading to cognitive decline. These findings highlight the potential for the early predictive value of medical conditions with chronic lipid dyshomeostasis for the risk of depression and cognitive decline.
