Embedded Printing of Hydrogels and Watery Suspensions of Cells in Patterned Granular Baths.

Bioprinting within support media has emerged as the superior alternative to conventional extrusion printing. Not only because it allows for more freedom over the shapes that can be printed but also because it allows for the printing of inks that would not retain shape fidelity in freeform deposition such as watery liquids. Apart from functioning as mechanical support during embedded printing, hydrogel microparticle support media can provide the unique advantage of offering distinct chemotactic cues to cells printed in the baths by varying the composition of the hydrogel microparticles. There is great potential in compartmentalized granular baths consisting of different hydrogel particle materials in the field of tissue engineering, as these allow for the local inclusion of properties or cues to guide tissue development. In this work, we present a method to create compartmentalized embedding baths by printing multiple granular hydrogel materials that are widely used in tissue engineering. After adapting the volume fraction (φp) of the particles in the bath, we print within them using both inks composed of hydrogel or of cells and other particles suspended in watery liquid. Our process consists of the following three steps: First, the hydrogel microparticles are packed at a φp that allows them to be extruded while being reversibly jammed, facilitating the localized deposition of the granular media to form a compartmentalized bath. Second, each granular media is deposited in succession to create a packed suspension compartment, and by adding liquid post deposition, φp is reduced to allow for embedded printing. Finally, we demonstrate the printing of multiple inks within the compartmentalized embedding bath and highlight the distinct differences between using inks composed of hydrogels or inks composed of particles suspended in watery liquid. This approach combines the advantages of embedded printing through the use of granular media with the added ability to pattern multiple bioactive granular materials to locally affect the behavior of cells printed within the bath. We expect that this workflow will allow researchers to create spatially compartmentalized, customized bioactive embedding baths that allow for the embedded printing of inks composed of hydrogels, cells, and other particles adapted to their need.

Motor symptoms of Parkinson's disease are affected by temperature: A controlled pilot study.

PURPOSE: The motor symptoms (MS) of Parkinson's disease (PD) have been affecting the quality of life in patients. In clinical practice, most patients with PD report that MS are more severe in winter than in summer, and hyperthermic baths (HTB) could temporarily improve MS. The study aimed to evaluate the effects of seasonal variation and aquatic thermal environment of HTB on the MS of PD. PATIENTS AND METHODS: A cross-sectional study of 203 Chinese Han patients was performed. Univariate and multivariate analyses were performed to analyze seasonal variation in MS relative to baseline data (sex, age at onset, duration, season of birth, Hoehn and Yahr stage, family history, levodopa equivalent dose, and the effect of HTB on MS). Ten subjects participated in the HTB study, and one patient dropped out. The paired Wilcoxon rank test was used to assess the differences in the Movement Disorder Society-United Parkinson's disease Rating Scale (MDS-UPDRS) part III motor examination total scores and the modified Webster Symptoms Score between non-HTB and before HTB and between non-HTB and after HTB. RESULTS: The improvement of MS after HTB was an independent risk factor for seasonal variation in MS (OR, 25.203; 95% CI, 10.951-58.006; p = .000). Patients with PD had significant improvements in the MDS-UPDRS part III motor examination total scores, especially in bradykinesia (p = .043), rigidity (p = .008), posture (p = .038), and rest tremor amplitude (p = .047). CONCLUSION: Seasonal variation in temperature and water temperature of HTB may affect MS in some patients with PD. Simple HTB could be recommended as physiotherapy for patients with PD who report temperature-sensitive MS.

Effect and Safety of Herbal Medicine Foot Baths in Patients with Diabetic Peripheral Neuropathy: A Multicenter Double-Blind Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect and safety of foot baths with Tangbi Waixi Decoction (TW) in treating patients with diabetic peripheral neuropathy (DPN). METHODS: It is a multicenter double-blinded randomized controlled trial. Participants with DPN were recruited between November 18, 2016 and May 30, 2018 from 8 hospitals in China. All patients received basic treatments for glycemic management. Patients received foot baths with TW herbal granules either 66.9 g (intervention group) or 6.69 g (control group) for 30 min once a day for 2 weeks and followed by a 2-week rest, as a therapeutic course. If the Toronto Clinical Scoring System total score (TCSS-TS) ⩾6 points, the patients received a total of 3 therapeutic courses (for 12 weeks) and were followed up for 12 weeks. The primary outcome was change in TCSS-TS score at 12 and 24 weeks. Secondary outcomes included changes in bilateral motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of the median and common peroneal nerve. Safety was also assessed. RESULTS: Totally 632 patients were enrolled, and 317 and 315 were randomized to the intervention and control groups, respectively. After the 12-week intervention, patients in both groups showed significant declines in TCSSTS scores, and significant increases in MNCV and SNCV of the median and common peroneal nerves compared with pre-treatment (P<0.05). The reduction of TCSS-TS score at 12 weeks and the increase of SNCV of median nerve at 24 weeks in the control group were greater than those in the intervention group (P<0.05). The number of adverse events did not differ significantly between groups (P>0.05), and no serious adverse event was related with treatment. CONCLUSION: Treatment of TW foot baths was safe and significantly benefitted patients with DPN. A low dose of TW appeared to be more effective than a high dose. (Registry No. ChiCTR-IOR-16009331).

Bleach suit for atopic dermatitis.

Bleach baths are an important adjunct in the management of atopic dermatitis. However, many homes do not have bath tubs. We tried to overcome this by soaking a cotton pajama suit or Indian kurta pajama in dilute bleach solution and then having the child wear it for ten minutes. This is done two to three times a week, as in standard bleach tub baths. We have tried this technique in eleven patients with satisfactory outcomes and no adverse effects.

Bathing in Atopic Dermatitis in Pediatric Age: Why, How and When.

Atopic dermatitis is a chronic inflammatory skin disease. The treatment plays an important role in influencing the patients' quality of life. The basic management consists of appropriate skin cleansing, including bathing and eventually using bathing additives. Recommendations regarding frequency and duration of bathing, water temperature and usefulness of bathing additives are widely different, often leading to confusion among patients. This review aims to give insights into the best bathing practices and the use of bathing additives in atopic dermatitis in children. Several bathing additives, including bleach baths, commercial baby cleansers, bath baby oils and bath salt, appear to be promising adjunctive therapies for atopic dermatitis due to their anti-inflammatory, anti-bacterial, anti-pruritus and skin barrier repair properties through different mechanisms of action. However, their efficacy and safety are not fully understood in some cases. The usefulness of other bath additives, such as acidic and more natural substances (green tea extracts, pine tar, sodium bicarbonate), is still under investigation. Further studies are needed to determine their optimal use to achieve clinical benefit safely.

A global survey on national standard care for newborn bathing.

AIM: To describe national standard care for newborn bathing and its influential factors. METHODS: A global survey was conducted using a web-based questionnaire. The targeted countries were 166 member countries of either the International Confederation of Midwives (ICM) or the International Council of Nurses (ICN). An eligible person included someone well informed of midwifery education/training or neonatal care, including newborn bathing, in their country. To examine the factors associated with the standard care for newborn bathing, information on mean annual temperature, precipitation, gross domestic product per capita, and basic water coverage was collected as external factors. Student's t tests and Chi-square tests were used for analysis. RESULTS: Care standards were identified in 46 countries: seven from Africa, eight from the Americas, 15 from Asia, 14 from Europe, and two from Oceania. In most countries, newborns were bathed with warm water in a tub within 10 min. Bathing frequency, moisturization, and use of soap or cleanser varied by country. There were significant associations between bathing frequency and temperature and between moisturization and precipitation. CONCLUSION: The national standard care for newborn bathing in each country was unique. Standard bathing care was associated with the climate. More consideration should be given to the differences in standard care for newborn bathing between countries when interpreting existing studies and conducting future studies on neonatal skin care.

Embedded 3D Bioprinting of Collagen Inks into Microgel Baths to Control Hydrogel Microstructure and Cell Spreading.

Microextrusion-based 3D bioprinting into support baths has emerged as a promising technique to pattern soft biomaterials into complex, macroscopic structures. It is hypothesized that interactions between inks and support baths, which are often composed of granular microgels, can be modulated to control the microscopic structure within these macroscopic-printed constructs. Using printed collagen bioinks crosslinked either through physical self-assembly or bioorthogonal covalent chemistry, it is demonstrated that microscopic porosity is introduced into collagen inks printed into microgel support baths but not bulk gel support baths. The overall porosity is governed by the ratio between the ink's shear viscosity and the microgel support bath's zero-shear viscosity. By adjusting the flow rate during extrusion, the ink's shear viscosity is modulated, thus controlling the extent of microscopic porosity independent of the ink composition. For covalently crosslinked collagen, printing into support baths comprised of gelatin microgels (15-50 µm) results in large pores (≈40 µm) that allow human corneal mesenchymal stromal cells (MSCs) to readily spread, while control samples of cast collagen or collagen printed in non-granular support baths do not allow cell spreading. Taken together, these data demonstrate a new method to impart controlled microscale porosity into 3D printed hydrogels using granular microgel support baths.

Effects of Bathing Skills Training on Independence and Satisfaction of Older Adults Living in a Nursing Home: A Randomized Controlled Trial.

Background: Dependence in bathing is the most common activities of daily living (ADLs) dependency among older adults. The aim of this study was to evaluate the effect of bathing skills training on the independence and satisfaction of older adults living in nursing homes. Methods: In this randomized controlled trial, 80 participants were assigned randomly to the intervention (n = 40) and control groups (n = 40). The intervention group received 10 weekly bathing skills training sessions, with each session lasting about 60 minutes, while the control group received no direct training. The evaluation was conducted using the Modified Barthel Index (MBI) and the Canadian Occupational Performance Measure (COPM). Analysis of variance for repeated measurements was used to test the effect of intervention at the baseline, post-intervention, and follow-up. Results: The mean improvement in the MBI was greater for the intervention group (P < 0.001; partial η2 = 0.34), which remained significant at the follow-up (P < 0.001; partial η2 = 0.41). The greater mean change of the COPM-Performance was significant in the intervention group (P < 0.001; partial η2 = 0.17), which remained significant at the follow-up (P < 0.001; partial η2 = 0.19). The greater mean improvement of the COPM-Satisfaction was observed for the intervention group (P < 0.001; partial η2 = 0.36), which remained at the follow-up (P = 0.001; partial η2 = 0.42). Conclusion: Bathing skills training is effective in improving the ADLs independence and satisfaction in older adults living in nursing homes; thus, it is recommended to be included in the schedules of nursing homes.

Fundamentals or Icing on Top of the Cake? A Narrative Review of Recovery Strategies and Devices for Athletes.

The sport and athletic performance industry has seen a plethora of new recovery devices and technologies over recent years, and it has become somewhat difficult for athletes, coaches, and practitioners to navigate the efficacy of such devices or whether they are even required at all. With the increase in recovery devices and tools, it has also become commonplace for athletes to overlook more traditional, well-established recovery strategies. In this narrative review, we discuss recovery strategies in relation to the hierarchy of scientific evidence, classifying them based on the strength of the evidence, ranging from meta-analyses through to case studies and reports. We report that foam rolling, compression garments, cryotherapy, photobiomodulation, hydrotherapy, and active recovery have a high level of positive evidence for improved recovery outcomes, while sauna, recovery boots/sleeves, occlusion cuffs, and massage guns currently have a lower level of evidence and mixed results for their efficacy. Finally, we provide guidance for practitioners when deciding on recovery strategies to use with athletes during different phases of the season.

The effect of lavender foot baths on postoperative pain and sleep quality in comparison with foot baths with warm water only-A prospective randomized controlled study.

INTRODUCTION: The aim of the study was to investigate the effect of warm water (WW) foot bath with or without lavender oil for pain and sleep quality in the patients who undergone abdominal surgeries. MATERIALS AND METHOD: This study was designed as a prospective randomized controlled. The three study groups were defined as the control group (n = 44), the WW foot bath group (n = 46), WW foot bath with the lavender group (n = 40). Foot baths were done for 20 min with 40 °C every night for 3 days after surgery. Visual Analogue Scale and Richard-Campbell Sleep Questionnaire were used during data collection. RESULTS: A total of 130 patients, mean age 55.99 ±  ± 13.05 years, 66 male (51 %), 103 of whom underwent abdominal surgery, were included in the study. When the patients during the postoperative three days were evaluated, decreased pain score and increased sleep quality both the WW and WW foot bath with lavender groups (p < 0.001). Noise-related sleep quality was detected to be lesser in the control group patients on the 3rd day (p < 0.001). CONCLUSION: WW foot bath with or without lavender oil is an uncomplicated, economical, and effective complementary therapy to reduce postoperative pain and improve sleep quality. WW foot baths with essential oils are optionally available in clinics and can be used according to patients' preferences.

Bleach baths enhance skin barrier, reduce itch but do not normalize skin dysbiosis in atopic dermatitis.

Studies have demonstrated that bleach baths improve atopic dermatitis (AD) severity; however, the effects on itch, skin barrier, and cutaneous microbial composition are less clear. We examined whether bleach baths reduce itch, normalize skin barrier function, reduce S. aureus absolute abundance, and increase microbial diversity in adults with AD who were colonized with S. aureus on their non-lesional skin. This was an open label, non-randomized, controlled trial performed at a single academic center. Fifteen AD and five non-atopic healthy controls (NA) were instructed to take two bleach baths (0.005% NaClO; 5-10 min duration) per week for a total of 12 weeks as add-on therapy. Adults 18 to 65 years (inclusive) with mild to severe AD were recruited with EASI score > 6.0, S. aureus culture positivity, access to a bathtub, and ability and willingness to maintain current topical or systemic treatments. They were evaluated at baseline (before bleach baths), 6 weeks, and 12 weeks after the intervention of twice-weekly bleach baths. Efficacy measurements included EASI as well as 5-D Pruritus and ItchyQoL™. Transepidermal water loss (TEWL) and stratum corneum (SC) integrity assay were performed to assess the skin barrier. Skin dysbiosis was measured by S. aureus cultivation, S. aureus abundance (qPCR of thermonuclease gene), and V1-V3 16S rRNA gene sequencing on non-lesional and lesional AD skin. After 12 weeks of bleach baths, 8/15 (53.3%) AD subjects achieved an EASI50 and a significant reduction in itch as measured by 5-D pruritus and Itchy QoL. Eighty-seven percent reported improvements in sleep quality. At study entry, AD subjects had higher non-lesional TEWL values than NA subjects, and only AD subjects experienced a reduction with bleach baths (p = 0.006). Similarly, SC integrity improved as early as 6 weeks after bleach baths in AD subjects. Notably, bleach baths had no significant effect on S. aureus culture-positivity, qPCR absolute abundance, or microbial diversity. The addition of twice-weekly bleach baths improves investigator-assessed AD severity, patient-reported pruritus and sleep as well as physiological measures of skin barrier function in adult AD subjects while having no effect on qualitative and quantitative measures of cutaneous S. aureus. Trial Registration: ClinicalTrials.gov Identifier: NCT01996150, Date of registration: November 27th, 2013.

Comparison of the Effects of Bathing and the Dry Technique on the Skin Condition of Early Neonates: A Prospective Observational Study.

BACKGROUND: In Japan, neonates have typically been bathed in a bathtub immediately after birth because bathing is a custom for cleansing impurities. However, dry technique has been introduced into many institutions since 2000. There is little scientific evidence on the benefit or harmfulness of either method to neonatal skin, and consequently, opinion remains split on which method is superior. OBJECTIVE: The purpose of the present study was to determine whether bathing or the dry technique of cleaning is better in maintaining skin health in the early neonatal period. METHODS: Transepidermal water loss (TEWL) and skin pH, considered an index of skin barrier function, were measured in each group. Tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, which are inflammatory cytokines released by keratinocytes, were measured by skin blotting. RESULTS: TEWL and skin pH of neonates were lower with the dry technique than with bathing. The expression level of IL-6 and TNF-α in chest skin of neonates was higher with bathing than with the dry technique. CONCLUSION: These results suggest that the dry technique may maintain skin health better than bathing in the early neonatal period.

Nationwide Database Analysis of Risk Factors Associated with Decreased Activities of Daily Living in Patients with Alzheimer's Disease.

BACKGROUND: Preserving activities of daily living (ADL) is the key issue for Alzheimer's disease (AD) patients and their caregivers. OBJECTIVE: To clarify the ADL level of AD patients at diagnosis and the risk factors associated with decreased ADL during long-term care (≤3 years). METHODS: Medical records of AD patients in a Japanese health insurance claims database were analyzed retrospectively to determine ADL using the Barthel Index (BI) and identify the risk factors associated with decreased ADL. RESULTS: A total of 16,799 AD patients (mean age at diagnosis: 83.6 years, 61.5% female) were analyzed. Female patients were older (84.6 versus 81.9 years; p < 0.001) and had lower BI (46.8 versus 57.6; p < 0.001) and body mass index (BMI) (21.0 versus 21.7 kg/m2; p < 0.001) than male patients at diagnosis. Disability (BI≤60) increased at age≥80 years and was significantly higher in females. Complete disability was most frequent for bathing and grooming. Risk factors for decreased ADL were determined separately by sex through comparing the ADL-preserved and ADL-decreased groups using propensity score matching by age and BI and multivariable logistic regression analysis. In males, decreased ADL was significantly associated with BMI < 21.5 kg/m2, stroke, and hip fracture, and inversely associated with hyperlipidemia. In females, decreased ADL was significantly associated with BMI < 21.5 kg/m2 and vertebral and hip fractures, and inversely associated with lower back pain. CONCLUSION: AD patients with low BMI, stroke, and fractures had increased risks of decreased ADL; such patients should be identified early and managed appropriately, including rehabilitation to preserve ADL.

Association of soap use when bathing 18-month-old infants with the prevalence of allergic diseases at age 3 years: The Japan Environment and Children's Study.

BACKGROUND: Atopic march is defined as the progression from atopic dermatitis (AD) during early life to other allergic diseases in later childhood. In a nationwide birth cohort study, the Japan Environment and Children's Study, we investigated the association of bathing habits, which are known to affect skin conditions, for infants with their later development of allergic diseases. METHODS: Pregnant women who lived in 15 designated regional centers throughout Japan were recruited. We obtained information on bathing habits for their 18-month-old infants and the prevalence of allergic diseases when they were aged 3 years. RESULTS: Data for 74,349 children were analyzed. Most 18-month-old infants were bathed or showered almost every day. When they were divided into four groups according to the frequency of soap use during bathing (every time, most of the time, sometimes, and seldom), the risk of AD later at age 3 was shown to increase in association with a decreasing frequency of soap use [most of the time: adjusted odds ratio (aOR) 1.18, 95% confidence interval (CI) 1.05-1.34; sometimes: aOR 1.72, 95% CI 1.46-2.03; seldom: aOR 1.99, 95% CI 1.58-2.50], compared with soap use every time during bathing at 18 months of age. Similar results were obtained for food allergy but not for bronchial asthma. CONCLUSIONS: Frequent soap use when bathing 18-month-old infants was associated with a decreased risk of them developing allergic diseases at age 3. Further well-designed clinical studies are warranted to determine an effective bathing regimen for preventing the development of allergic diseases.

Reduction in patient refusal of CHG bathing.

BACKGROUND: Daily chlorhexidine gluconate (CHG) bathing is a well-supported intervention to reduce patient's risk of central line associated bloodstream infection (CLABSI); however, compliance with this practice is suboptimal. One major barrier is patient refusals of CHG bathing. The purpose of this project was to implement tailored interventions to mitigate this barrier. The specific aims were to reduce patient refusals, increase compliance with CHG bathing, and evaluate CLABSI rates and nursing staff's knowledge of CHG bathing. METHODS: Iterative Plan-Do-Study-Act (PDSA) cycles were implemented over the course of 6 months. Run charts were used to identify signals of improvement. Interventions included printed educational flyers for staff and patients, educational sessions, an electronic learning module, and a "badge buddy." RESULTS: We saw a reduction in the median percentage of patient refusals documented, from 23% to 8% after the PDSA cycles. Documentation compliance with CHG bathing increased only slightly from 46% to 47%. CLABSI rates decreased 6% from 0.69 to 0.65. DISCUSSION: Using interventions tailored to the clinical setting can impact patient outcomes. Other health care systems should consider implementing PDSA cycles to improve evidence-based practices. CONCLUSIONS: Using PDSA cycles can result in a reduction in patient refusal documentation, and may slightly improve CHG bathing compliance and CLABSI rates.

Thermodynamics of Quantum Spin-Bath Depolarization.

We analyze here through exact calculations the thermodynamical effects in depolarizing a quantum spin-bath initially at zero temperature through a quantum probe coupled to an infinite temperature bath by evaluating the heat and entropy changes. We show that the correlations induced in the bath during the depolarizing process does not allow for the entropy of the bath to increase towards its maximal limit. On the contrary, the energy deposited in the bath can be completely extracted in a finite time. We explore these findings through an exactly solvable central spin model, wherein a central spin-1/2 system is homogeneously coupled to a bath of identical spins. Further, we show that, upon destroying these unwanted correlations, we boost the rate of both energy extraction and entropy towards their limiting values. We envisage that these studies are relevant for quantum battery research wherein both charging and discharging processes are key to characterizing the battery performance.

Minimum wiping pressure and number of wipes that can remove dirt during bed baths using disposable towels: a multi-study approach.

BACKGROUND: Friction irritation by wiping increases the risk of skin problems. In bed baths with cotton towels, wiping three times with weak pressure (10-20 mmHg ≈ 1333-2666 Pa) can remove dirt while maintaining skin barrier function. However, few studies have examined the appropriate frictional irritation with disposable towels. This study aimed to analyse the wiping pressure and number of wipes currently applied by nurses when using disposable towels during bed baths and propose the minimum values for removing dirt from the skin. METHODS: This multi-study approach consisted of cross-sectional and crossover design components. In Study 1, 101 nurses in two hospitals were observed by recording the wiping pressure and number of wipes when using both disposable (nonwoven) and cotton (woven) towels. Wiping pressure and number of wipes by towel materials were analysed using a linear mixed model. In Study 2, 50 adults received oily and aqueous dirt on their forearms, which were wiped six-times with disposable towels, applying randomly assigned pressure categories. We used colour image analysis and a linear mixed model to estimate the dirt removal rate for each combination of wiping pressure and number of wipes. RESULTS: Study 1 showed that although wiping pressure did not differ by towel material, the number of wipes was significantly higher for disposable wipes than cotton wipes. Approximately 5% of nurses applied strong wiping pressure or wiped too often. In Study 2, wiping three times with disposable towels at least 5-10 mmHg achieved dirt removal rates of ≥80%. CONCLUSIONS: Some nurses excessively wiped using disposable towels, which might cause skin problems. However, excessive wiping is not required to adequately remove dirt, regardless of the towel material used in various clinical situations. We recommend wiping at 10-20 mmHg of pressure (just like stroking gently) at least three times to improve the quality of bed baths. These findings highlight the need to develop skin-friendly bed bath educational programmes, particularly using appropriate frictional irritation to reduce the risk of skin problems.
