The effect of heated humidified carbon dioxide on postoperative pain, core temperature, and recovery times in patients having laparoscopic surgery: a randomized controlled trial

STUDY OBJECTIVE: To determine whether use of heated humidified carbon dioxide as insufflation gas during gynecologic laparoscopy reduced postoperative pain and hypothermia. DESIGN: A randomized controlled trial (Canadian Task Force classification 1). SETTING: A tertiary referral hospital. PATIENTS: Sixty women scheduled for gynecologic laparoscopy between 30 and 90 minutes' duration. INTERVENTIONS: Operative laparoscopic management of endometriosis, adhesions, or adnexal pathology. MEASUREMENTS AND MAIN RESULTS: Sixty patients were randomized into either receiving heated humidified carbon dioxide (study group) or standard cold dry gas (control group). Intraoperative and postoperative core temperature, total analgesic use, postoperative nausea, and recovery room time were recorded. Postoperative pain intensity was assessed using visual analog scale. Statistical analysis was performed using software. No significant difference was revealed between groups with regard to postoperative pain, analgesic requirements, recovery room time, or postoperative nausea. The control group had less postoperative hypothermia, suggesting that external warming blankets may be more effective than heated humidified gas at maintaining intraoperative normothermia. CONCLUSION: The use of heated humidified carbon dioxide insufflation for short-duration gynecologic laparoscopy up to 90 minutes' duration was not associated with any significant benefit with regard to postoperative pain, hypothermia, or time of recovery room stay.     

Aplasia cutis congenita, terminal limb defects and falciform retinal folds: confirmation of a distinct syndrome of vascular disruption

We describe a son of consanguineous parents with congenital scalp defects, transverse limb abnormalities, hypoplasia of the corpus callosum and bilateral falciform retinal folds. Aplasia cutis congenita with transverse limb defects are features of Adams-Oliver syndrome, which is usually inherited as an autosomal dominant condition. The association of bilateral retinal folds and brain abnormalities with scalp defects and terminal limb defects has only once been previously described. It is possible that these cases represent a severe variant of Adams-Oliver syndrome. We, however, suggest that they may characterize a new, distinct, autosomal recessive syndrome, involving vascular disruption.     

Natural Volcanic Material as a Sustainable Photocatalytic Material for Pollutant Degradation under Solar Irradiation

Recently, photocatalysis has been demonstrated as a solid approach for efficient wastewater cleaning. Using natural materials as photocatalysts means a promising solution to develop green catalysts for environmental purposes. This work aimed to study the suitability of a natural volcanic material (La Gomera, Canary Islands, Spain) as a photocatalytic material for the degradation of pollutants in wastewater with solar energy. After analysing the properties of the natural material (BET surface 0.188 m²/g and band-gap of 3 eV), the photocatalytic activity was evaluated at laboratory and pilot plant scale for the degradation of methylene blue (MB) in water (50 mg L⁻¹), at 20 °C, during a period of 4 h, under UV/Vis light and solar irradiation. Photolytic and adsorption studies were developed to distinguish the photocatalytic contribution to the wastewater decontamination process by photocatalysis. Our results enable us to determine the viability of black sand as a photocatalytic material activated by solar irradiation (photodegradation of MB up to 100% by using solar energy), developing a natural and green photocatalytic system with significantly high potential for application in a sustainable wastewater cleaning process.     

Physical function and health-related quality of life of community-dwelling older adults with locomotive syndrome and pre-frailty

[Purpose] To consider the effective rehabilitation approaches for locomotive syndrome (LS) and pre-frailty, we examined the characteristics of physical function and health-related quality of life (HRQoL) in community-dwelling older adults. [Participants and Methods] Eighty-three individuals (age 71.8 ± 5.5 years, 29 males and 54 females) were divided into robust (R), LS, and locomotive syndrome with pre-frailty (LSP) groups. We compared the subscale and summary scores of the 36-Item Short-Form Health Survey (SF-36) as HRQoL indices. The grip strength, five-chair stand up test (SS-5), and normal walking speed were the physical function indices. [Results] The LS group had lower two-step scores and normal walking speed but there was no significant difference in the SF-36. The two-step score and 25-question geriatric locomotive function scale, SS-5, seven SF-36 subscales, and mental component summary (MCS) scores were lower in the LSP group. Compared to that of the LS group, the LSP group did not show significant difference in physical function but showed lower values in overall health, vitality, mental health, and MCS in the SF-36 subscales. [Conclusion] The subjective evaluation of one’s health was lower than that of the deterioration of physical function as a characteristic of the LSP.     

Family mealtime emotions and food parenting practices among mothers of young children: Development of the Mealtime Emotions Measure for Parents (MEM‐P)

Family mealtimes can be important for supporting children''s healthy development, yet the emotional context of mealtimes can vary considerably, likely impacting their overall success and enjoyment. Yet, despite having an important role, little is known about how parents emotionally experience mealtimes with their family. The first aim of the current study was to assess the factor structure of a novel self‐report measure to assess parents’ emotional responses experienced during family mealtimes (Mealtime Emotions Measure for Parents; MEM‐P). The second aim was to examine relationships between maternal mealtime emotions and their food parenting practices. Mothers of children aged between 1.5 and 6 years participated in this study. Mothers were invited to complete an online questionnaire measuring family mealtime emotions, anxiety, depression and food parenting practices. Exploratory factor analysis produced a three‐factor solution comprising both positive and negative emotion subscales: MEM‐P Efficacy; MEM‐P Anxiety; MEM‐P Stress and Anger. Mothers'' positive mealtime emotions (mealtime efficacy) were related to greater use of practices promoting autonomy, providing a healthy home food environment, and modelling healthy eating. Higher anxiety about mealtimes was related to greater reports of child control over eating, and mealtime stress and anger was associated with greater use of food to regulate emotions. These findings highlight novel relationships between how mothers emotionally experience family mealtimes and the food parenting practices they use with their children. It is important to develop resources to help promote positive maternal experiences of family mealtimes and food‐based interactions.
