Zoom & WhatsApp Digital Information and Communication Technologies (ICTs) Enhance Community Engaged Research with Women Immigrants from Mexico.

This article demonstrates how digital information and communication technologies (ICTs) (Zoom/WhatsApp) unexpectedly and counterintuitively proved to be valuable tools for community-engaged health research when, in the context of the COVID-19 pandemic, they were integrated into a research study testing a peer support group intervention with female immigrants from Mexico. Because of pandemic restrictions, we changed the study protocol to hold meetings remotely via Zoom rather than in person as originally planned. Because we recognized that this would lack some opportunities for participants to interact and develop relationships, we created a WhatsApp chat for each group. Despite challenges for participants to use ICTs and participant-stated preference for in-person meetings, the results demonstrated that participants overwhelmingly endorsed these technologies as promoting access, participation, engagement, and satisfaction. Zoom/WhatsApp created a valuable environment both as a method for conducting research with this population, but also as part of the intervention for immigrant women to support and learn from each other. ICT adaptations have now permanently changed the way we conduct community-engaged health research.

Advancing Intraoperative Neurophysiological Monitoring With Human Reflexes.

Human reflexes are simple motor responses that are automatically elicited by various sensory inputs. These reflexes can provide valuable insights into the functioning of the nervous system, particularly the brainstem and spinal cord. Reflexes involving the brainstem, such as the blink reflex, laryngeal adductor reflex, trigeminal hypoglossal reflex, and masseter H reflex, offer immediate information about the cranial-nerve functionality and the overall state of the brainstem. Similarly, spinal reflexes such as the H reflex of the soleus muscle, posterior root muscle reflexes, and sacral reflexes provide crucial information about the functionality of the spinal cord and peripheral nerves. One of the critical benefits of reflex monitoring is that it can provide continuous feedback without disrupting the surgical process due to no movement being induced in the surgical field. These reflexes can be monitored in real time during surgical procedures to assess the integrity of the nervous system and detect potential neurological damage. It is particularly noteworthy that the reflexes provide motor and sensory information on the functional integrity of nerve fibers and nuclei. This article describes the current techniques used for monitoring various human reflexes and their clinical significance in surgery. We also address important methodological considerations and their impact on surgical safety and patient outcomes. Utilizing these methodologies has the potential to advance or even revolutionize the field of intraoperative continuous monitoring, ultimately leading to improved surgical outcomes and enhanced patient care.

Equipos de protección personal en odontología antes y después de la COVID-19

El uso de equipamientos de protección personal durante los tratamientos odontológicos garantiza la salud de profesionales y pacientes. Este trabajo tiene como propósito analizar, en la literatura científica, el conocimiento de estudiantes y profesionales de odontología sobre el uso de equipos de protección personal, antes y después de la pandemia COVID-19. Para ello se realizó una revisión integrativa en las bases de datos: Scielo, Pubmed, BVS y Web of Science, incluyendo artículos publicados entre agosto del 2010 y agosto del 2022. Fueron seleccionados 14 artículos, disponibles íntegramente en las bases de datos seleccionadas. Se excluyeron tesis, artículos de revisión, duplicados y aquellos donde la metodología no respondía al objetivo propuesto. En los 14 artículos seleccionados, el método para obtención de datos fue el cuestionario. Los estudios fueron realizados en Brasil, Yemen, Cuba, México, Líbano, Turquía, India, Londres, y Colombia. Seis estudios se realizaron antes de la pandemia y 8 de ellos después de su inicio. Todas las investigaciones evaluaban conocimientos, actitudes, prácticas y factores relacionados con el uso de equipos de protección personal. Se concluye que el uso de equipos de protección personal antes de la pandemia ya era una práctica esencial para garantizar la seguridad de profesionales, estudiantes y pacientes durante los procedimientos odontológicos; con la pandemia de COVID-19 nuevos protocolos fueron establecidos y con ellos nuevos equipamientos como el uso del protector facial y la mascarilla N95.

The use of personal protective equipment during dental treatments guarantees the professionals and patients' health. This researcher's purpose is to analyze in scientific literature the dental students and professionals' knowledge regarding the use of personal protective equipment, before and after the COVID-19 pandemic. An integrative review was carried out in the databases: Scielo, Pubmed, BVS and Web of Science, including articles published between August 2010 and August 2022. 14 articles were selected, available in full in the selected databases. Theses, review articles, duplicates and those where the methodology did not respond to the proposed objective were excluded. In the 14 selected articles, the method for obtaining data was the questionnaire. The studies were carried out in Brazil, Yemen, Cuba, Mexico, Lebanon, Turkey, India, London, and Colombia. Six studies were carried out before the pandemic and 8 of them after its start. All researches evaluated knowledge, attitudes, practices and factors related to the use of personal protective equipment. It is concluded that the use of personal protective equipment before the pandemic was already an essential practice to guarantee the safety of professionals, students and patients during dental procedures; with the COVID-19 pandemic, new protocols were established and with them new equipment such as the use of the face shield and the N95 mask.

The blink reflex and its modulation - Part 1: Physiological mechanisms.

The blink reflex (BR) is a protective eye-closure reflex mediated by brainstem circuits. The BR is usually evoked by electrical supraorbital nerve stimulation but can be elicited by a variety of sensory modalities. It has a long history in clinical neurophysiology practice. Less is known, however, about the many ways to modulate the BR. Various neurophysiological techniques can be applied to examine different aspects of afferent and efferent BR modulation. In this line, classical conditioning, prepulse and paired-pulse stimulation, and BR elicitation by self-stimulation may serve to investigate various aspects of brainstem connectivity. The BR may be used as a tool to quantify top-down modulation based on implicit assessment of the value of blinking in a given situation, e.g., depending on changes in stimulus location and probability of occurrence. Understanding the role of non-nociceptive and nociceptive fibers in eliciting a BR is important to get insight into the underlying neural circuitry. Finally, the use of BRs and other brainstem reflexes under general anesthesia may help to advance our knowledge of the brainstem in areas not amenable in awake intact humans. This review summarizes talks held by the Brainstem Special Interest Group of the International Federation of Clinical Neurophysiology at the International Congress of Clinical Neurophysiology 2022 in Geneva, Switzerland, and provides a state-of-the-art overview of the physiology of BR modulation. Understanding the principles of BR modulation is fundamental for a valid and thoughtful clinical application (reviewed in part 2) (Gunduz et al., submitted).

Our voices, our lives: Unforeseen stories after the violence and opening the door to becoming whole again.

We are a group of 11 women in Albuquerque, New Mexico. Nine of us are immigrants from Mexico. One of us is from an immigrant household. One of us is neither. We have been working collaboratively on a research study called Tertulias (Spanish for "a social gathering"), which is an innovative women's peer support group approach we created to reduce social isolation, depression, and stress among women immigrants from Mexico, and to increase their resilience and sense of empowerment. In the process of implementing the Tertulias study, we are revealing the profound power of peer support, friendship, and small, quotidian kindnesses. But we are also exposing the immensity and scope of trauma, fear, loneliness, depression, and self-blame that exist in the Mexican immigrant community because of domestic violence. Our experience with domestic violence and with the consciousness-raising and support we found in Tertulias has made us want to be involved in a positive manner to do something about this issue in our community. We want our experience to mean something-to be used to make a difference. We are opening our hearts and sharing our stories and ideas. We wanted to be included as co-authors of this article because we want our stories to be received and heard by other women. We want to plant seeds to help other women find their inner strength to be able to escape from their chains. We have to return for others. It is a commitment-to understand how we were able to do it and share that with others. Through our experience participating in Tertulias, we learned that we could overcome what felt overwhelming and impenetrable. We could leave the violence and rediscover and recreate ourselves and our lives.

Effect of a 24-Week Concurrent Exercise Intervention on Neck Adiposity and Its Distribution in Young Adults: The ACTIBATE Randomized Controlled Trial.

Neck adipose tissue (NAT) accumulation and neck circumference are independent predictors of cardiometabolic risk (CMR) and low-grade chronic inflammation in young adults. The present study examines whether a 24-week concurrent exercise intervention can reduce NAT volume and neck circumference in young adults, and whether any changes in these variables are related to changes in body composition, CMR, and the inflammatory profile. Seventy-four participants (51 women, age 22 ± 2 years) were included in the main analyses, after being randomly assigned to either a (a) control (n = 34), (b) moderate-intensity exercise (n = 19), or (c) vigorous-intensity exercise (n = 21) group. Participants in the exercise groups trained 3-4 days/week (endurance + resistance exercise training). NAT volume and NAT distribution across different depots were estimated using computed tomography before and after the intervention. Anthropometric variables, body composition (determined by dual-energy X-ray absorptiometry), and CMR/inflammatory markers were also recorded. The exercise intervention did not reduce the total NAT volume, nor was NAT distribution affected (p > .05). However, it did reduce neck circumference in the vigorous-intensity exercise group compared with the moderate-intensity exercise and control groups (by 0.8 and 1 cm, respectively, p ≤ .05). Changes in total NAT and neck circumference were positively, albeit weakly, related (adj. R2: .05-.21, all p ≤ .05) to changes in body weight and adiposity, leptin (only total NAT), and CMR (only neck circumference). Altogether 24 weeks of concurrent exercise does not appear to reduce NAT accumulation in young adults, but may slightly reduce neck circumference in those who partake in vigorous exercise.

Unexpected median SEPs fluctuations during brain cavernous malformation resection with no post-operative deficit.

Median nerve somatosensory evoked potentials (SEPs) may present changes during cavernous malformation (CM) resection unrelated to new post-operative sensory deficits. We performed intraoperative neurophysiological monitoring of median SEPs (m-SEPs) in three patients who underwent CM resection (surgery) near the sensory-motor cortex. The only preoperative clinical manifestations in all patients were seizures. All patients presented m-SEPs alterations on the side of the lesion during the procedure. Two patients presented permanent changes in the cortical potentials. In the third patient, the cortical and subcortical components suffered temporal fluctuations to return to baselines at the end of the surgery. None of these patients developed new post-operative clinical deficits. During brain cavernous malformation resection, significant fluctuations in the amplitude of different components of m-SEPs may occur. These changes may be due to excitability variations on m-SEP generators and do not translate into new post-operative neurological deficits.

Median nerve somatosensory evoked potential alarm related to head and neck positioning for carotid surgery.

Head positioning in carotid surgery represents an often overlooked but sensitive period in the surgical plan. A 53-year-old male presented a significant decrement in median nerve somatosensory evoked potential (mSEP) following head and neck positioning for carotid pseudoaneurysm repair before skin incision.Neurophysiological monitoring was performed with mSEP and electroencephalography early during the patient's preparation and surgery. Within five minutes after rotation and extension of the head to properly expose the surgical field, the contralateral m-SEP significantly decreased in both cortical (N20/P25) and subcortical (P14/N18) components. Partial neck correction led to m-SEP improvement, allowing to proceed with the carotid repair. We discuss possible underlying pathophysiological mechanisms responsible for these changes and highlight the relevance of an early start on monitoring to avoid neurological deficits.

Continuous intraoperative neuromonitoring of the recurrent laryngeal nerve by eliciting the laryngeal adductor reflex (LAR-CIONM).

The laryngeal adductor reflex (LAR) is a life-sustaining airway protective mechanism that serves to shield the lower airways from inhaled foreign bodies. Over the past half century, the LAR has been extensively investigated and its dysfunction has been linked to far-ranging pathologies, from dysphagia to sudden infant death syndrome. Over the past 6 years, specific electromyographic waves in the LAR response have been used to devise a methodology for monitoring the vagus and recurrently laryngeal nerves during surgical procedures. This methodology involves continuous intraoperative neuromonitoring of the laryngeal adductor reflex and isthus termed 'LAR-CIONM'. In this review paper, the physiology of the LAR will be summarized as it relates to LAR-CIONM and the technique of LAR-CIONM will be described. Applications of this technique and published outcomes of LAR-CIONM will be highlighted.

No evidence of brown adipose tissue activation after 24 weeks of supervised exercise training in young sedentary adults in the ACTIBATE randomized controlled trial.

Exercise modulates both brown adipose tissue (BAT) metabolism and white adipose tissue (WAT) browning in murine models. Whether this is true in humans, however, has remained unknown. An unblinded randomized controlled trial (ClinicalTrials.gov ID: NCT02365129) was therefore conducted to study the effects of a 24-week supervised exercise intervention, combining endurance and resistance training, on BAT volume and activity (primary outcome). The study was carried out in the Sport and Health University Research Institute and the Virgen de las Nieves University Hospital of the University of Granada (Spain). One hundred and forty-five young sedentary adults were assigned to either (i) a control group (no exercise, n = 54), (ii) a moderate intensity exercise group (MOD-EX, n = 48), or (iii) a vigorous intensity exercise group (VIG-EX n = 43) by unrestricted randomization. No relevant adverse events were recorded. 97 participants (34 men, 63 women) were included in the final analysis (Control; n = 35, MOD-EX; n = 31, and VIG-EX; n = 31). We observed no changes in BAT volume (Δ Control: -22.2 ± 52.6 ml; Δ MOD-EX: -15.5 ± 62.1 ml, Δ VIG-EX: -6.8 ± 66.4 ml; P = 0.771) or 18F-fluorodeoxyglucose uptake (SUVpeak Δ Control: -2.6 ± 3.1 ml; Δ MOD-EX: -1.2 ± 4.8, Δ VIG-EX: -2.2 ± 5.1; p = 0.476) in either the control or the exercise groups. Thus, we did not find any evidence of an exercise-induced change on BAT volume or activity in young sedentary adults.

Circulating concentrations of free triiodothyronine are associated with central adiposity and cardiometabolic risk factors in young euthyroid adults

Thyroid dysfunction is associated with classic cardiometabolic risk factors in humans. However, this relationship remains unclear in young euthyroid adults. The present work examines the associations of circulating thyroid hormones (THs) and thyroid-stimulating hormone (TSH) concentrations with body composition and cardiometabolic risk factors in young euthyroid adults. A total of 106 sedentary, euthyroid adults (72 women; 22 ± 2 years old) participated in this cross-sectional study. THs and TSH serum concentrations were determined in fasting conditions (6 h). Body composition (fat mass (FM), lean mass (LM), and visceral adipose tissue (VAT)) was determined by dual-energy X-ray absorptiometry, anthropometric parameters (weight, height, and waist circumference) were measured, and neck adipose tissue mass was quantified through computed tomography (CT) scanning. Cardiometabolic risk factors including fasting glucose and lipid metabolism markers, hepatic phosphatase and transaminases, and blood pressure were also assessed. Free triiodothyronine (FT3) concentration was positively associated with body mass index, LM, VAT, and waist circumference (all P ≤ 0.038). FT3 was also associated with glucose, insulin, HOMA-IR, fatty liver index, and blood pressure (all P < 0.024). All the associations were attenuated when adjusting for sex. In contrast, we found no associations of TSH or free thyroxine with any body composition parameter or cardiometabolic risk factors. In conclusion, FT3 is associated with central adiposity and cardiometabolic risk factors including insulin resistance, fatty liver index, and mean, systolic and diastolic blood pressure in young euthyroid adults.

Abstract Introduction: With the social isolation imposed by the Covid 19 pandemic, teleworking in the home office modality has been an alternative used by some companies. Objective: To determine the impact of this remote work on the integral health of workers. Methodology: A cross-sectional study was carried out, through the "Google Forms" platform, a semi-structured questionnaire was elaborated that was sent to 150 information technology workers from a medium-sized municipality in the state of São Paulo, to obtain information on the variables: age, sex, working conditions, oral and systemic health, oral hygiene habits, musculoskeletal pain, physical exercises and emotional state. Results: Of the total of 116 responses received, 87.07% belonged to the male sex, 100% reported concern with their oral and general health, 56.03% reported changes in their eating habits, 44.83% increased food consumption and 77.58% reported feeling concerned and anxious. The prevalence of painful musculoskeletal symptomatology manifested in 100% of workers predominantly found in the cervical region (53.44%). In general, low frequency of physical activity and inadequate conditions for home work performance were corroborated. Conclusions: The change from the usual work routine to the home office modality (teleworking) significantly impacted the health of information technology workers. Given the possibility of maintaining this modality of remote work to reduce the exposure and spread of the virus, it is necessary to adopt strategies to preserve the integral health of these professionals.

A Study of a Culturally and Contextually Situated Multimedia Approach to Recruit a Hard-to-Reach Spanish-Speaking Population for a Randomized Control Trial (RCT).

Study designs involving randomization can be difficult to communicate to participants, especially those with low literacy. The literature on strategies to explain research concepts is limited, especially for non-English speakers. We measured the effectiveness of a culturally and contextually situated multimedia approach to recruit a cohort of 60 female Mexican immigrants (FMI) to a randomized control trial (RCT) to reduce social isolation and depression. This strategy was designed to explain the concept of randomization, explain what participating in the research study entailed, and ensure informed consent. Potential participants viewed a presentation explaining the study and a video including animation with voice-over explaining the concept of randomization. We administered a pre/post survey. Respondents (N = 59) reported an increase in their understanding of randomization, intention to enroll, and attitude towards participating in research. We conclude that a culturally and contextually situated multimedia approach is an effective model when recruiting underrepresented populations with low literacy for RCTs.
