Assessing the Effect of Cool Roofs on Health Using Smartwatches in Colima, Mexico
Ambient air temperatures in Mexico have broken record highs in 2024. Solutions are needed to build heat resilience in communities and adapt to increasing heat from climate change. Sunlight-reflecting cool roof coatings may passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions in the northern zone of Mexico are susceptible to increased heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are experienced in communities that are least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use may promote heart health, sleep and physical activity in household occupants. The long-term research goal of the investigators is to identify viable passive housing adaptation technologies with proven health benefits to reduce the burden of heat stress in communities affected by heat in Mexico. To meet this goal, the investigators will conduct a randomized controlled trial to establish the effects of cool roof use on heart rate, sleep and physical activity in Colima, Mexico.

Assessing the Effect of Cool Roofs on Health Using Smartwatches
Ambient air temperatures in Asian, Latin American, African, and Pacific climate hotspots have broken record highs in 2024. Solutions are needed to build heat resilience in communities and adapt to increasing heat from climate change. Sunlight-reflecting cool roof coatings may passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions globally - for example in informal settlements, slums, and low-socioeconomic households - are susceptible to increased heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are experienced in communities that are least able to adapt to heat exposure. By reducing indoor temperatures, cool roof application may improve heart health, sleep and physical activity in household occupants. The long-term research goal is to identify viable passive housing adaptation technologies with proven health benefits to reduce the burden of heat stress in communities affected by heat globally. To meet this goal, the investigators will use smartwatches to measure the effects cool roof application on heart health, sleep and physical activity in four urban climate hotspots: Ouagadougou, Burkina Faso; Hermosillo, Mexico; Ahmedabad, India; and Niue, Oceania.

Effects of Music on Procedural Pain in Distal Radius Fracture Reduction
This randomized controlled trial (RCT) evaluates the effectiveness of music as a complementary intervention for pain control during non-surgical reduction of distal radius fractures in orthopedic patients. Distal radius fractures are among the most common traumatic injuries presenting to emergency departments and are frequently associated with intense procedural pain and significant physiological stress responses. Despite standard pharmacological analgesia, optimal pain management during fracture reduction remains a clinical challenge, and evidence regarding non-pharmacological adjuncts in the emergency orthopedic setting is still limited The study will enroll 192 adult patients admitted to the orthopedic emergency departments of AUSL Piacenza and AOU Parma with distal radius fractures requiring closed reduction. Participants will be randomly assigned (1:1:1) to one of three groups: a 20-minute session of patient-preferred music, a 20-minute session of standardized music selected by a music therapist, or standard care without music. Pain intensity will be assessed using the Numerical Rating Scale (NRS), while physiological stress will be evaluated through heart rate and blood pressure measurements, collected at baseline (T0) and 20 minutes later (T1), immediately after the reduction procedure The trial is designed as a prospective, randomized, controlled study with blinded data analysis, and all data will be collected and managed in compliance with current privacy and data protection regulations. By generating robust evidence on a low-cost, safe, and easily implementable intervention, the PolSound trial aims to improve procedural pain management and patient experience in emergency orthopedic care, potentially supporting the integration of music-based interventions into standard analgesic protocols.

Evaluation of the Impact of a Nutritional Formulation on Cognitive Performance Following Stress Exposure.
The proposed project will evaluate the synergistic effects of a nutritional formulation, 'Think Tank' on cognitive performance following exposure to a psychological and physical stressor. Adopting a double-blind repeated measures cross-over design, middle-aged females (40-60 years) will be recruited to take part in a two-stage research study that will examine whether the formulation enhances cognitive performance and subjective well-being following the challenge of a stressor, compared to placebo. Cognitive assessments will examine the impact of the nutritional formulation on working memory, sustained attention, cognitive flexibility and inhibitory control. The study will also assess physiological (heart rate, blood pressure and cortisol) and subjective (well-being, anxiety, positive and negative mood, stress) markers of stress reactivity. The study will also explore levels sleep quality, mental and physical fatigue, effort, productivity, and perceived impact of the intervention.

Development of Artefact Removal and Physical Activity Algorithm
This clinical trial will collect heart rate (HR) data with the Fitbit Inspire 2 fitness tracker and Polar H10 chest strap with the aim of: * Goal 1. Optimising and validating our artefact removal procedure. * Goal 2. Developing a physical activity (PA) algorithm to follow and quantify day-to-day PA based on HR measurements. A pilot study will be conducted with a total of 46 cardiac patients (group 1), 46 coached sporters with 12-week training schedule (group 2) and 46 sporters without 12-week training schedule (group 3). The three groups all engage in controlled activities. The participants' HR will be monitored continuously for an average period of 13 weeks using 2 HR monitors, i.e. the Fitbit Inspire 2 fitness tracker and the Polar H10 chest strap. They will wear the Fitbit device continuously for the whole monitoring period, while they will wear the Polar chest strap continuously for the first 24 hours and after that only during exercise. To determine participants' exercise capacity (e.g. VO2max), cardiopulmonary exercise tests (CPETS) will be carried out. For group 1, 3 CPETS will take place during the CR programme: at the start, in the middle and at the end. For group 2 and group 3, 2 CPETS will be carried out at the start and the end of the study. The monitoring period with Fitbit and Polar will end at the last CPET. All participants will record their daily efforts in an activity diary during the first week of study. Moreover, two questionnaires will be conducted at the end of the study to evaluates usability and experiences with the HR monitors.

Validation of Vital Signs Recording With VT-Patch Connected Devices in Children
: Patient readmission to PICU is a major point of concern for physicians because, although being a rare event, it has been strongly associated with more morbidity and death. Patient monitoring once they have left the PICU is drastically modified, and small connected devices could be an option to early identify patients at risk of PICU readmission. Such devices have been manufactured for the recording of vital signs in adults, but they do not exist for children. Besides, studies have recently shown that devices that use optical sensors may be less accurate in individuals with dark skin pigmentation since dark skin tones impose a limitation on optical biometric sensing. The wearable and medical device industry has not sufficiently addressed this issue yet. This is one of the main challenges that need to be addressed in this area to make sure the connected devices using this technology will work with all different skin colours including very dark skin.

Balance, Autonomic Response, and Sensory Modulation to Dosage of Mechanical Vagal Stimulation in Healthy Adults
The vagus nerve (VN) plays a crucial role in regulating vital functions (heart rate, blood pressure, digestion, and immune response) and maintaining communication between internal organs and the brain. Recent studies have highlighted the therapeutic potential of VN stimulation (VNS) in treating various conditions such as drug-resistant epilepsy, postural control deficit, COVID-19 infection, chronic pain, and intestinal disorders. In addition, there is growing evidence that the molecules released by the VN neurons affect the function of the gut microbiota and that the molecules released by the bacteria in our gut affect the activity of the VN neurons. In particular, Dr. Giacomo Carta (the leader of this study) has shown how painless neck movements, i.e. mechanical VNS (mVNS), can be applied without adverse effects, representing a potential alternative to invasive methods commonly used today. To further investigate the impact of this novel mVNS, this study aims to evaluate the changes induced by three mVNS protocols on physiological parameters such as resting heart rate, and Heart Rate Variability (HRV) at rest, balance in standing, the perceived intensity of mechanical stimuli using the established clinical method of QST (quantitative sensory testing), fecal transit speed, and the molecular composition of stool (for this, stool samples are analyzed). In particular, stool analysis is very relevant for understanding normal digestion. The present research aims to define the optimal intensity of mVNS and to investigate the therapeutic potential of VNS in the treatment of autonomic dysfunction (such as too low or too high heart rate, too low or too fast digestion, throbbing headaches), as well as falls prevention and pain.

The Study is About the influence of the Combination of Music and Noise Cancelling as a Non-pharmacological Aid in Reducing Anxiety and Discomfort During Wisdom Tooth Removal. The Level of Fear is Measured by a Questionnaire Which the Patients Answer Twice and a Measurement of the Heartbeat
The goal of this clinical trial is to learn if the reduction of the noises (through head phones with music and noise cancelling) that occur during wisdom teeth removal, leads to a significant reduction in fear levels in patients compared to patients who do not have any noise reduction. The main questions it aims to answer are: Do music and noise cancelling help patients to have less fear during wisdom teeth removal surgery by reducing the sounds of the surgery? Is there a difference between just the noise cancelling function or is it better to combine noise cancelling and music together? Participants will: Just come to their regular appointment (wisdom teeth removal) to our clinic, no follow ups needed. All participants will answer one questionnaire before and one after the surgery. All of them will have their rate of heartbeat measured for three times (before, during and after surgery, measured by a puls oximeter on the finger). They will be allocated to one of the three study groups (no headphones, headphones with noise cancelling or headphones with noise cancelling and music).

Effects of Sleep Body Temperature on Body Composition
This will be a crossover controlled trial designed to recruit 40 participants, who will be divided into two groups of 20 subjects each. The participants will be randomly assigned to either Group A or Group B. Group A will receive the sleep electric blanket intervention for a period of 7 days, while Group B will serve as the control group without any additional intervention. After the intervention period, there will be a washout period of 7 days to ensure that any effects of the intervention have subsided before the crossover. Following the washout period, the groups will switch roles: Group B will then receive the sleep electric blanket intervention, and Group A will become the control group. This second phase will also last for 7 days, preceded and followed by the same assessment procedures as the initial phase. This design will allow for a comparison of the intervention's effects against a control period within the same group of participants, enhancing the study's internal validity.
