RESUMO

INTRODUCTION: Telehealth has emerged as a promising supplementary modality in prenatal care. However, its impact on patient-provider communication (PPC), especially among pregnant women from underserved settings, requires comprehensive evaluation. This study examined the factors associated with the quality of patient-provider communication during the COVID-19 pandemic among pregnant telehealth users and non-users. METHODS: Using a cross-sectional study design, 242 women were surveyed (response rate = 23%) regarding their experience with telehealth, quality of PPC, and experiences of discrimination during prenatal care. Multiple regression models were used to identify the factors associated with the quality of PPC during the COVID-19 pandemic. A sub-group analysis explored the factors associated with the quality of PPC separately among telehealth users and non-users. RESULTS: The majority of the participants were on Medicaid (95%) and self-identified as Black/African American (57.3%). Regression analyses revealed a negative relationship between telehealth use during pregnancy and the quality of PPC (ß = -1.13, P = 0.002). Irrespective of the telehealth use, the experience of discrimination was associated with poor quality of PPC among users (ß = -3.47, P = .02) and non-users (ß = -.78, P = .03), while adjusting for sociodemographic factors and social support during pregnancy. DISCUSSION: While telehealth offers advantages like convenience, increased accessibility, and continuity of care, challenges in establishing effective PPC in virtual settings have emerged that emphasize the necessity for comprehensive provider training extending beyond technical competencies. The persistent issue of perceived discrimination, impacting PPC across both groups, underscores the necessity to rethink existing strategies of mandatory training to increase providers' knowledge.

RESUMO

Objectives: Dementia, often misperceived as an inherent facet of aging, is, in fact, a progressive neurodegenerative condition. It carries a significant stigma due to its associated psychological and behavioral manifestations, leading to neglect and abuse within households. Studies reveal an alarming 90% treatment gap for dementia in India, largely due to limited knowledge about symptom recognition and accessing services. Thus, enhancing dementia literacy becomes crucial for early diagnosis and proper management. This study aims to assess dementia literacy and familiarity with the term "dementia" in a North Indian tertiary health-care setting. Materials and Methods: This cross-sectional study used a case vignette method among patients and their attendants at psychiatry outpatient setting in a tertiary care hospital. A validated Hindi-translated case vignette depicting a dementia patient was employed. The study gathered sociodemographic data, the case vignette, and three related questions. Participants read the vignette and provided answers. The analysis included 200 responses collected in 1 month. Results: Respondents predominantly associated the case's condition with memory issues, mental illness, and psychosocial factors. They suggested social support, a nurturing family environment, communal living, and consulting a doctor for the protagonist. Familiarity with "dementia" was at a mere 24%. Conclusion: Dementia literacy and awareness of "dementia" are notably low in our sample. Urgent efforts are required to enhance dementia awareness to facilitate timely prevention, early detection, and effective management.

RESUMO

INTRODUCTION: In the United States, 1 in 6 women reports obstetric violence in the form of physical and verbal abuse, coercion, and lack of informed consent. Despite recommendations against routine episiotomy, its use in the United States remains notable and varies considerably. This study aimed to analyze the various forms of obstetric violence associated with undergoing an episiotomy and having a choice in undergoing an episiotomy. METHODS: Data from the cross-sectional Listening to Mothers in California survey were analyzed using weighted sample. Logistic regression models were conducted to compute adjusted odds ratios (aORs) and 95% CIs for undergoing episiotomy and having a choice in it. RESULTS: Overall, 21% of the respondents reported undergoing an episiotomy, and 75% of them reported not having a choice in undergoing this procedure. After adjusting for covariates, feeling pressured to induce labor (aOR, 1.31; 95% CI, 1.28-1.35) and to use an epidural analgesia (aOR, 1.82; 95% CI, 1.77-1.88) increased the odds of undergoing an episiotomy. Having a midwife during childbirth significantly reduced the odds of an episiotomy. Respondents who indicated being handled roughly by health care providers were 95% less likely to have a choice in receiving an episiotomy (aOR, 0.05; 95% CI, 0.04-0.06). DISCUSSION: This is the first study to examine other forms of obstetric violence as correlates of episiotomy and having a choice in it. Standardized institutional measures against obstetric violence, patients' ability to make autonomous decisions through informed consent, and engaging midwives could decrease medically unnecessary labor procedures and associated complications.

RESUMO

Introduction: Abdominal wall blocks, in conjunction with multimodal analgesia, have demonstrated efficacy in providing post-operative analgesia, reducing opioid requirements in patients undergoing inguinal hernia repair. The inguinal region is primarily innervated by the ilioinguinal nerve (IIN) and iliohypogastric nerve (IIH). Posterior transverse abdominis plane block (pTAP) and fascia transversalis plane block (TFP) have been observed to reliably block IIN and IIH. We hypothesized that posterior TAP block (pTAP) owing to its potential paravertebral spread will provide better post-operative analgesia than TFP block in patients undergoing unilateral open inguinal hernia repair. Methods: This prospective, randomized, single-blind, two-arm parallel study was conducted over a duration of one year for which sixty patients undergoing unilateral open inguinal hernia repair under spinal anesthesia were enrolled. They were equally and randomly assigned to receive either preoperative pTAP block or TFP block. The primary aim of the study was to compare median static and dynamic NRS scores during a 24-hour period, with the secondary aim to compare the number of patients who required rescue analgesics in each group. Results: All enrolled patients completed the study. Results showed no statistically significant difference in median static NRS scores between Group pTAP and Group TFP at the designated time of observation during the 24-hour period [1.2 (0.4-1.60 vs. 1 (0.6-1)]. Group pTAP reported a higher median dynamic NRS scores during the 24-hour period [2.6 (1.2-3) v/s 2 (1.6-2.4); P < 0.035], although this difference was clinically insignificant. The mean time to request for the first rescue analgesia was comparable (11.7 h v/s 12 h; P = 0.99). In all the patients of both groups, loss of pinprick and cold touch sensation was observed at T10, T12, and L1 dermatomal levels. However, sensory assessment at T6 and T8 levels showed variability between the two groups (P > 0.05). Conclusion: In conjunction with background analgesia and the use of dexamethasone as an adjuvant, both blocks (pTAP and TFP) were observed to be equally effective for post-operative pain relief with similar patient satisfaction scores.

RESUMO

Objectives: Pain is classified as nociceptive, neuropathic, or nociplastic. Neuropathic pain presents as variable phenotypes (characters) based on specific aetiology and pathophysiology. This study aimed to find out among cancer patients the incidence of different phenotypes of neuropathic pain and form specific phenotypic clusters based on the underlying neurophysiology and association of sensory profile with various organ systems - A prospective observational study. Materials and methods: The Institutional Ethical Committee clearance (IEC code: 2020-49-MD-EXP-15) https://ctri.nic.in/Clinicaltrials/showallp.php?mid1=44886&EncHid=88651.15716&userName=CTRI/2020/09/027964 approval was obtained. After written and informed consent, patients of age group 18-80 years, registering in the pain and palliative outpatient department or radiotherapy department with complaints of pain and not taking any anti-neuropathic pain medications, were enrolled. They were assessed using Leeds assessment of neuropathic symptoms and signs (LANSS) pain score, and a score of >12 was eligible for assessment of neuropathic pain phenotypes. Results: Out of 210 cancer patients complaining of pain, a neuropathic component with LANSS >12 was found in 73 (34.76%). The most predominant phenotypes, allodynia> tingling> pricking = burning, were found in 72.60%, 56.16%, and 43.84% of patients, respectively. Phenotypes were clustered into Nodes 1 and 2 based on clinically significant separation of phenotypes. Node 1 had neuropathic pain of spontaneous origin found predominantly in gastrointestinal tract (GIT) and genitourinary tract (GUT) cancers. Node 2 had stimulus-evoked negative and positive characters which occurred in head and neck, thoracic, and spinal metastatic cancers. Conclusion: Careful patient assessment reveals the incidence of neuropathic pain in 34.76%; allodynia and tingling astable the most prominent phenotypes. Broadly, sensory characters were clustered into spontaneous and stimulus-evoked sensations with GIT and GUT cancers presenting with Node 1 symptoms.

RESUMO

BACKGROUND: Ohio ranks 43rd in the nation in infant mortality rates (IMR); with IMR among non-Hispanic black infants is three times higher than white infants. OBJECTIVE: To identify the social factors determining the vulnerability of Ohio counties to IMR and visualize the spatial association between relative social vulnerability and IMR at county and census tract levels. METHODS: The social vulnerability index (SVICDC) is a measure of the relative social vulnerability of a geographic unit. Five out of 15 social variables in the SVICDC were utilized to create a customized index for IMR (SVIIMR) in Ohio. The bivariate descriptive maps and spatial lag model were applied to visualize the quantitative relationship between SVIIMR and IMR, accounting for the spatial autocorrelation in the data. RESULTS: Southeastern counties in Ohio displayed highest IMRs and highest overall SVIIMR; specifically, highest vulnerability to poverty, no high school diploma, and mobile housing. In contrast, extreme northwestern counties exhibited high IMRs but lower overall SVIIMR. Spatial regression showed five clusters where vulnerability to low per capita income in one county significantly impacted IMR (p = 0.001) in the neighboring counties within each cluster. At the census tract-level within Lucas county, the Toledo city area (compared to the remaining county) had higher overlap between high IMR and SVIIMR. CONCLUSION: The application of SVI using geospatial techniques could identify priority areas, where social factors are increasing the vulnerability to infant mortality rates, for potential interventions that could reduce disparities through strategic and equitable policies.

RESUMO

This paper focuses on the ethical tensions seen in health systems research by researchers owing to their scientific obligations to their research, ethical obligations to study participants, and social obligations to the community. Health systems research differs from other public health research fields in terms of the participants selected, power relations within health systems and the socio-political environment. The study seeks to answer the following questions through experiences in health system research. 1. What are the ethical tensions experienced by researchers in field work? 2. How are the existing guidelines used in resolving tensions arising in field work in India? To understand these ethical tensions, the World Health Organization's Ethical Considerations for Health Policy and Systems Research were applied to research conducted in the health system settings. These tensions faced by researchers are explained through four emerging themes: the researcher's position in the health system; voluntariness of participation: participation; and social justice.

RESUMO

BACKGROUND: Meaningful interprofessional education (IPE) involves students from at least two professions interacting to learn with, about, and from one another. Our objective was to describe a novel online approach used to create meaningful IPE within a social determinants of health (SDoH) workshop. INTERPROFESSIONAL EDUCATION ACTIVITY: This online workshop integrated four different professions' perspectives on SDoH (social-work, public-health, nursing, and pharmacy). Each six-student interprofessional team was assigned a local neighborhood. This week-long workshop had numerous activities (pre- and post-workshop quizzes, a SDoH-primer video, video self-introduction to teammates, a windshield questionnaire with two subsequent clinical cases, a post-workshop reflection, and post-workshop evaluation). For discussion, asynchronous video-based responses were used instead of traditional text-based discussion-boards. DISCUSSION: Quantitatively comparing quiz scores, students' SDoH knowledge increased with this workshop. Qualitatively from evaluations, most students found this workshop helpful and meaningful. Supporting use of video-based responses, many students' favorite aspect was interacting and collaborating within their interprofessional teams, although some students desired synchronous activities instead. Faculty facilitators confirmed that meaningful IPE interactions occurred. IMPLICATIONS: In short, students from multiple health-professions learned SDoH-content and, using video-based responses, interacted asynchronously during this online workshop. This report demonstrated one tool available to help facilitate meaningful IPE asynchronously. This asynchronous, online IPE workshop appears to be a promising format to be integrated with other in-person IPE sessions.

RESUMO

This study aimed to examine changes in health behaviors and outcomes during early-pandemic (2020) vs pre-pandemic (2019) years by age groups and race/ethnicity. Multivariable logistic regressions were conducted using Behavioral Risk Factor Surveillance System datasets from 2019 (n = 418 268) and 2020 (n = 401 958). All participants reported less likelihood to exercise (aOR, .78; 95% CI: .73-.83) and have poor physical health (aOR, .91; 95% CI: .86-.98) but more likelihood to have excellent general health (aOR, 1.33; 1.17-1.53) during 2020 vs 2019. Compared to 2019, during 2020 (i) Blacks were more likely to exercise (aOR, 1.24; 95% CI: 1.02-1.51) and have excellent general health (aOR, 1.69; 95% CI: 1.13-2.54); (ii) Hispanics were less likely to exercise (aOR, .80; 95% CI: .74-.88), but more likely to have excellent general health (aOR, 2.44; 95% CI: 1.79-3.33) and mental health (aOR, 1.41; 95% CI: 1.15-1.72); and (iii) Whites were less likely to exercise (aOR, .58; 95% CI: .50-.67) and have good physical health (aOR, 0.89; 95% CI: .82-.95). All age groups, except 18-24 years, were less likely to exercise by 18%-39% during 2020 vs 2019. Furthermore, the 55-64 years age-group was 36% more likely to report excellent general health but 14% less likely to have good physical health. Identifying the most vulnerable racial/ethnic and age groups is pivotal to prioritizing public health resources and interventions to mitigate the impact of health crises.

RESUMO

Local health departments (LHDs) play a leading role in eliminating health inequities as they proactively identify and address barriers to optimal health within the community they serve. This study evaluated a Midwestern County LHD's commitment, collaborations, and capacity to advance health equity in their organization. A total of 81 employees completed the online survey (response rate = 51%) and 12 among randomly selected employees completed the qualitative interviews (31.5%). More than 75% of participants reported that all departments had explicit work plans and 50% had a strong capacity to address social determinants of health. Almost 50% of the participants reported strong internal collaboration, but less than 25% indicated that no external partners were involved during the program planning process. Finally, a few participants identified the need for increased diversity in leadership and expressed the importance of quality training and feedback.

RESUMO

BACKGROUND: Opioid Use Disorder (OUD) is a major public health concern, with mortality rates in individuals who use opioid medications being up to 30 times greater than those of individuals who do not use such medications. Social risk factors influence one's ability to make healthy choices and pose challenges for individuals recovering from OUD. OBJECTIVE: This study aimed to explore the relationship between OUD and social risk factors for patients who have been prescribed opioid medications. METHODS: Data for this retrospective cohort study were obtained from a health care system's comprehensive data warehouses consisting of electronic health records (EHR) with Social Determinants of Health (SDoH) screening information, and medical and prescription claims data. The study compared patients 18 years of age or older with an opioid prescription who were considered users of opioids to patients who had a documented diagnosis of OUD in the EHR. All patients were screened for SDoH. The analyses were performed using Statistical Analysis System (SAS) (SAS Institute Inc, Cary, NC). RESULTS: The study included patients with an outpatient visit at one of the health care system's primary care or oncology facilities between January 1, 2017 and December 31, 2018. There were 5003 patients with an opioid prescription who were considered users of opioids, and 209 patients with an opioid prescription as well as a diagnosis of OUD. Compared to the opioid use group, patients with OUD were more likely to have a lower educational attainment, encounter financial hardship, or be food insecure. Being female, older than 40, and having a higher Charlson Comorbidity Index score were factors associated with lower rates of opioid misuse. CONCLUSION: Identifying social risk factors and providing appropriate services to individuals with OUD is essential in mitigating challenges to recovery and promoting overall health for these individuals.

RESUMO

Cryptochromes (CRYs) are a class of photoreceptors that perceive blue/ultraviolet-A light of the visible spectrum to mediate a vast number of physiological responses in bacteria, fungi, animals and plants. In the present study, we have characterized OsCRY2 in a photoperiod sensitive indica variety, Basmati 370, by generating and analyzing overexpression (OE) and knock-down (KD) transgenic lines. The OsCRY2OE lines displayed dwarfism as shown in their reduced plant height and leaf length, attributed largely by an overall reduction in their cell size. The OsCRY2OE lines flowered significantly earlier and showed shorter and broader seeds with an overall reduced seed weight. The OsCRY2KD lines showed contrasting phenotypes, such as increased plant height and delayed flowering, however, decreased seed size and weight were also observed in the KD lines, along with reduced spikelet fertility and high seed shattering rate in mature panicles. Novel interactions were confirmed between OsCRY2 and members of ZEITLUPE family of blue/ultraviolet-A light photoreceptors, encoded by OsFBO8, OsFBO9 and OsFBO10 which are orthologous to ZEITLUPE (ZTL), LOV KELCH PROTEIN2 (LKP2) and FLAVIN BINDING, KELCH REPEAT F-BOX1 (FKF1), respectively, of Arabidopsis thaliana. Since FKF1 is known to play a role in regulating photoperiodic flowering, OsFBO10 was chosen for further studies. OsCRY2 and OsFBO10 interacted in the nucleus and cytoplasm of the cell and cross-regulated the expression of each other. They were also found to regulate the expression of several genes involved in photoperiodic flowering in rice. Both OsCRY2 and OsFBO10 played a positive role in photomorphogenic responses in different light conditions. The physical interaction of OsCRY2 with OsFBO10, their involvement in common physiological and developmental pathways and their cross-regulation of each other suggest that the two photoreceptors may regulate common developmental pathways in plants, either jointly or redundantly.

RESUMO

BACKGROUND: Even though onset of three-quarters of mental disorders occurs by age 25, few young adults seek help for their mental health needs. The objectives of this study are to examine the relationship of discrimination and stigma of mental illness on the help-seeking behavior for mental health among college students. METHOD: Undergraduate students (N = 557) at a Midwestern university were surveyed online. Descriptive and logistic regression analysis was conducted using STATA15. RESULTS: College students reporting higher discrimination were more likely to seek help for mental health services (OR = 1.04, CI = 1.01-1.06), after controlling for all covariates. Students with higher personal stigma reported lower odds of help-seeking behavior (OR = 89, CI = .80-.97). Students with higher perceived public stigma did not have an independent significant association on help-seeking behavior initially, but full model revealed a significantly association (OR = 1.02, CI = .99-1.05). CONCLUSION: Developing targeted interventions addressing discrimination and stigma of mental illness is critical among college students.

RESUMO

Even though patient portals are recognized as a promising mechanism to support greater patient engagement, questions remain about access and utilization. This study aims to identify factors related to portal adoption in 2019 and 2020 (before and during the COVID-19). Cross-sectional data from the Health Information National Trends Survey (HINTS) cycles- 2019 HINTS 5 cycle 3 (N = 5,438) and 2020 HINTS 5 cycle 4 (N = 3,865) were analyzed using STATA-SE version 17 to factors predicting portal adoption. Next, HINTS 5 cycles 3 and 4 were pooled to identify changes in portal feature use and ease of usage among portal users, and barrier to portal use among non-users. Respondents who were college graduates, high income, and married were more likely to adopt patient portals during 2019 and 2020. Aged 75+ and Hispanic respondents reported less frequency of portal access in 2020 versus 2019. Men were more likely to adopt patient portals in 2019 versus women in 2020. Portal users were more likely to use the portal-system features in 2019 versus 2020. Portal non-users reported having multiple-health records as less of a barrier in 2020 compared to 2019. Patient engagement needs heightened attention during the COVID-19 pandemic.

RESUMO

KEY MESSAGE: OsiCRY2 is involved in light-regulated plant development and plays a role in regulating photomorphogenesis, plant height, flowering and most strikingly partial photomorphogenesis in dark. Cryptochrome 2 (CRY2), the blue/UV-A light photoreceptor in plants, has been reported to regulate photoperiod-dependent flowering and seedling photomorphogenesis (under low-intensity light). Among monocots, CRY2 has been reported from japonica rice, wheat, sorghum and barley. The two sub-species of rice, indica and japonica, exhibit a high degree of genetic variation and morphological and physiological differences. This article describes the characterization of CRY2 of indica rice (OsiCRY2). While the transcript levels of OsiCRY2 did not change significantly under blue light, its protein levels were found to decline with increased time duration under blue light. For phenotypic characterization, OsiCRY2 over-expression (OX) transgenics were generated in Oryza sativa Pusa Sugandh 2 (PS2) cultivar, a highly scented Basmati cultivar. The OsiCRY2OX transgenics displayed shorter coleoptiles and dwarfism than wild-type under blue light, white, and far-red light. Interestingly, even the dark-grown transgenics were shorter, concomitant with higher OsiCRY2 protein levels in transgenics than wild-type. Histological analysis revealed that the decrease in the length of the seedlings was due to a decrease in the length of the epidermal cells. The fully mature rice transgenics were shorter than the untransformed plants but flowered at the same time as wild-type. However, the OsiCRY2 Arabidopsis over-expressors exhibited early flowering by 10-15 days, indicating the potential and conservation of function of OsiCRY2. The whole-genome transcriptome profiling of rice transgenics revealed the differential up-regulation of several light-regulated genes in dark-grown coleoptiles. These data provide evidence that OsiCRY2 regulates photomorphogenesis, plant height, and flowering in indica rice.

RESUMO

Patients with neurovascular disorders sometimes approach the ophthalmologists with mild ophthalmic clinical features such as conjunctival congestion, slowly progressive proptosis, lateral rectus palsies and at other times with ophthalmic emergencies like sudden increase in proptosis, ophthalmoplegia, diplopia, and ptosis before the onset of neurological manifestations which may be life-threatening if not detected in time. The aim of this article is to focus on ophthalmic manifestations of neurovascular emergencies and role of ophthalmologists in its management. In this communication, to make the ophthalmologist aware of clinical presentations, the imaging modality of choice, diagnostic features, medical and interventional treatments. We have searched PubMed, Web of Science, Google Scholar and reviewed some of the commonly encountered neurovascular emergencies with ocular manifestations such as carotid-cavernous fistula, cerebral venous sinus thrombosis, cerebral artery aneurysms, arterio-venous malformations.

RESUMO

BACKGROUND: Our study aimed to compare pectoral nerve (PEC) block with local anesthetic (LA) infiltration for providing analgesia in superficial breast surgeries. MATERIALS AND METHODS: This prospective comparative randomized study included seventy American Society of Anesthesiologists I and II female patients undergoing excision of fibroadenoma. In Group 1, the LA mixture was infiltrated in the desired planes. In Group 2, PEC I and PEC II blocks were performed under ultrasound guidance. Patients were observed at regular time intervals for pain scores, time to first analgesic request, and the number of patients requiring rescue analgesia with the cumulative analgesic requirement, hemodynamic changes, and any adverse events. RESULTS: The patients were comparable in demographic profile, duration of anesthesia, and hemodynamic parameters. NRS scores at all times after extubation were significantly lower in Group 2 as compared to Group 1 (P < 0.0001). All patients in Group 1 required additional analgesia, while only two in Group 2 received rescue analgesia (P < 0.0001). The time to first analgesic request was significantly longer in Group 1 as compared to group 2 (9.5 + 0.70 h vs. 1.35 + 0.83 h) (P < 0.0001). The cumulative requirement of tramadol in Group 1 (96.88 ± 16.45 mg) was significantly higher than in Group 2 (6.47 ± 26.38 mg) (P < 0.0001). No adverse event was reported in either group. CONCLUSION: PEC block is a useful method for achieving effective and long-lasting analgesia. It is an efficient and safe alternative to LA infiltration in patients undergoing fibroadenoma excision.

RESUMO

Cryptochrome 2 (CRY2) perceives blue/UV-A light and regulates photomorphogenesis in plants. However, besides Arabidopsis, CRY2 has been functionally characterized only in native species of japonica rice and tomato. In the present study, the BnCRY2a, generating a relatively longer cDNA and harboring an intron in its 5'UTR, has been characterized in detail. Western blot analysis revealed that BnCRY2a is light labile and degraded rapidly by 26S proteasome when seedlings are irradiated with blue light. For functional analysis, BnCRY2a was over-expressed in Brassica juncea, a related species more amenable to transformation. The BnCRY2a over-expression (BnCRY2aOE) transgenics developed short hypocotyl and expanded cotyledons, accumulated more anthocyanin in light-grown seedlings, and displayed early flowering on maturity. Early flowering in BnCRY2aOE transgenics was coupled with the up-regulation of many flowering-related genes such as FT. The present study also highlights the differential light sensitivity of cry1 and cry2 in controlling hypocotyl elongation growth in Brassica. BnCRY2aOE seedlings developed much shorter hypocotyl under the low-intensity of blue light, while BnCRY1OE seedling hypocotyls were shorter under the high-intensity blue light, compared to untransformed seedlings.
