Published: September 2021

Introduction:
High-percentage outpatient total joint arthroplasty (TJA) performed in a safety net hospital system has not been described. A rapid recovery protocol (RRP) was instituted at our safety net hospital that allowed eventual transition to outpatient TJA.

Methods:
Retrospective review of all primary total knee and hip arthroplasty performed by a single surgeon (RR) using an RRP was performed. The initial cohort of patients was monitored overnight with the goal of next-day discharge (n = 57), and as the RRP evolved, the subsequent cohort of patients had the possibility of same-day discharge (PSDD, n = 61). Outcome measures included the rate of same-day discharge in the PSDD cohort and short-term adverse event rates.

Results:
In the PSDD cohort, 86.9% (n = 53) of patients were successfully discharged on the day of surgery, and hospital length of stay was decreased by 17.7 hours (13.5 versus 31.2 hours, P < 0.0001). Comparing the next-day discharge and PSDD groups, no significant differences were found in 30-day emergency department visits (5.3% versus 3.3%, P = 0.67), 90-day complications (15.8% versus 13.1%, P = 0.79), 90-day readmissions (0% versus 3.3%, P = 0.50), or 90-day revision surgeries (0% versus 3.3%, P = 0.50).

Conclusions:
This study demonstrates that the transition to outpatient TJA can be successfully performed in a safety net hospital system without increasing short-term adverse events.

Letter to Peter Hoefnagels
This is a letter written by Brigitte Chin-A-Fat to the late Peter Hoefnagels, who was one of the Dutch pioneers in the field of divorce mediation and a professor of criminology and family law at Erasmus University Rotterdam. In 1997, TMD published an article from his hand in which he wrote how he had become inspired by the potential of divorce mediation and about his (first) experiences with this ‘new’ mode of dispute resolution in family disputes. The original article by Peter Hoefnagels, dating from 1997, is reproduced in 2021 in TMD in view of its relevance today and precedes the letter by Brigitte Chin-A-Fat.Hoefnagels invented the so-called ‘divorce announcement’ and introduced psychology to the legal world of divorce and family mediation. Anno 2021, there are many (legal) developments which are bound to have an impact on the reform of Dutch divorce procedure.The Dutch government has set up pilot projects experimenting with inter alia a ‘joint access’ to the family court. Many of these developments are in line with Hoefnagels’ suggestions to avoid harm being inflicted on the ex-spouses and notably their children to the largest extent possible. The author discusses some of the current pilot projects and connects the rationale underlying these experiments to Hoefnagels’ ideas as presented 25 years ago. She also looks into the future, notably which changes are likely to occur in the next 25 years in the field of divorce mediation.

Published: September 2021

Water is one of the most essential requirements for living being to survive because 70–80% of the mass of most living bodies consists of water and various mineral and organic salts. Water is also most important component of our environment. Large amount of water is used in various industries or commercial level or domestic level and finally effluent water is loaded with large amount of pollutants such as organic chemicals (surfactants, dyes, phenols etc.), inorganic hazardous heavy metals (As in present case) microbes (bacteria, fungi etc.) pollutants particulate etc. Arsenic is a natural metalloid chemical that may be present in groundwater and surface water gets polluted, hence, aquatic life of plants and animals is disturbed and cause abnormal growth and various diseases, hence, short term or long term changes occurs in ecosystem. Hence, treatment of wastewater is essentially required before discharge effluent wastewater into ponds or lagoons, drains and rivers. Arsenic is one such element that contaminates the environment as reported in several countries. The largest population at risk is in Bangladesh followed by India (West Bengal). Arsenic is familiar as silent killer because dissolved in water, it is colorless, odorless, and tasteless, yet consumption of relatively small doses of this element in its most toxic forms can cause rapid and violent death. It is a human carcinogen in water over a wide range of pH values, having harmful effects on both human health and environment, even at low concentration. Because of this effect, the World Health Organization (WHO) and the US Environmental Protection Agency (USEPA) set the arsenic standard for drinking water at .010 ppm to protect consumers served by public water systems. Ingestion only poses health problems if a dangerous amount of arsenic enters the body. Then, it can lead to cancer, liver disease, coma, and death. There is no effective treatment for arsenic toxicity. Only the removal of arsenic from aqueous system can prevent the toxicity. A great deal of research over recent decades has been done to lower the concentration of arsenic in drinking water and still there is a need to develop ecofriendly techniques. Existing major arsenic removal technologies include oxidation, adsorption, precipitation, coagulation and membrane separation. This book chapter presents a systematic description of current status of research in the area of arsenic removal from contaminated water and comparison of all technologies available with more emphasis on adsorption.

Published: September 2021

Background The increasing number of bilateral breast cancer patients has been accompanied by a growing need for bilateral mastectomy with immediate reconstruction. However, little research has investigated the complications and aesthetic outcomes related to bilateral reconstruction. Therefore, we analyzed retrospective data comparing the outcomes of bilateral reconstruction using deep inferior epigastric perforator (DIEP) flaps or implants.
Methods This study included 52 patients (24 DIEP group and 28 implant group) who underwent bilateral mastectomy with immediate reconstruction between 2010 and 2020. Patient demographics, surgical characteristics, and complications were recorded. The difference between the left and right position of the nipple-areolar complex with respect to the sternal notch point at the clavicle was measured, and breast symmetry was evaluated.
Results The average weight of breasts reconstructed with DIEP flaps (417.43±152.50 g) was higher than that of breasts with implants. The hospitalization period and operation time were significantly longer in the DIEP group. Early complications were significantly more common in the implant group (36.53%) than in the DIEP group. The angles between the nipples and the horizontal line were 1.09°±0.71° and 1.75°±1.45° in the DIEP and implant groups, respectively.
Conclusions Although the surgical burden is lower, breast reconstruction using implants requires greater attention with respect to implant positioning, asymmetry, and complications than DIEP flap reconstruction. DIEP flap reconstruction has a prolonged operation time and a high risk of flap failure, but yields excellent cosmetic results and does not require intensive follow-up. Patients should be consulted to determine the most suitable option for them.

Published: September 2021

AbstractThe diagnosis of the main complications resulting from lipoabdominoplasty has not yet been standardized. Infrared thermal imaging has been used to assess possible complications, such as necrosis and changes in micro- and macro-circulation, based on perforator mapping techniques, among others. The objective of this study was to present two clinical cases involving thermal imaging monitoring of the healing process of lipoabdominoplasty in the immediate postoperative evaluation and its preliminary results. Infrared thermography was performed 24 hours after the operation and on postoperative days 5, 25, and 27. In clinical case 1, it was found that the delta-R (∆TR)–defined as the difference in minimum temperature between the highest and lowest points in the SA3 region (caution suction area) following the classification established by Matarasso–was 0.4°C at 24 hours after surgery and decreased to 0.1°C on a postoperative day 5. There were no complications in this case. In contrast, in clinical case 2, the ∆TR was 1.7°C at 24 hours after surgery (upon hospital discharge) and remained high, at 2.2°C, on postoperative day 5. A higher ∆TR was found in the second patient, who developed necrosis of the surgical wound. The ∆TR thermal index may be a new tool for predicting possible complications, complementing the clinical evaluation and therapeutic decision-making.

Published: September 2021

Aims: Human papillomavirus (HPV) infection is the most common sexually transmitted infection globally. Vaccination is effective in preventing HPV-associated cancers and is recommended for children at ages 11-12; however, the vaccination rate is suboptimal. Credible information about HPV vaccine in social media will help the public make effective healthcare decisions. This study analyzed YouTube videos about HPV vaccine.
Study Design: Descriptive study.
Place and Duration of Study: Videos in English posted on YouTube during 2006-2020.
Methodology: We used purposive sampling to select and conduct a quantitative content analysis of 151 YouTube videos that met the criteria. An instrument including video characteristics and theoretical constructs of the Health Belief Model was used to code the videos. Three researchers independently coded the data; another three verified the accuracy. The team discussed discrepancies until reaching a consensus. We conducted descriptive and inferential statistics.
Results: The major source of videos were medical centers/hospitals (26%), government (22%), media (20%), and consumers (15%). About 80% of the videos were positive in tone. Information covered included vaccine knowledge (85.4%), benefits (81.5%), severity if infected (79.5%), susceptibility (60.9%), and barriers (37.7%). The primary vaccination barriers were lack of knowledge of HPV and vaccine (12.6%), worries about adverse events/safety of vaccine (14.6%) and its side effects (9.3%). Videos in neutral tone had the highest number of views, likes and dislikes. Negative tone was mostly found in videos made by consumers and media while positive tone was found in videos made by governmental agencies and medical center/hospital.
Conclusion: Despite YouTube being a popular avenue to disseminate health information and influence care, the HPV-related information on YouTube is mixed. Anecdotal health information without scientific support can mislead individuals’ decision in vaccination. Educational videos with comprehensive and accurate HPV information addressing barriers are imperative to promote vaccination and prevent HPV-related cancers.

AbstractMetal ions have regulatory activities of multi‐tissue regeneration but usually interrupt early coagulation, resulting in an abnormal hematoma structure that is not conducive to long‐term repair or regeneration. To address free metal ions immobilization during the coagulation phase and effectively promote ionic bioactivities through controlled macrophage uptake after coagulation, metal ion “adjuvants” are required. [Si─O4] tetrahedron has a unique coordination tetrahedral structure to capture various metal ions and adsorb plasma proteins such as fibrinogen to facilitate macrophage uptake via receptor‐mediated endocytosis during the degradation of the fibrin network. Taking advantage of the hypoxia induction and tissue regeneration ability of copper ions, Cu[Si─O4] tetrahedrons are prepared which successfully immobilized copper ions and addressed the coagulation interruption. Cu[Si─O4] tetrahedrons effectively promote copper ionic uptake by macrophages via LRP1‐mediated endocytosis to create a hypoxia microenvironment and promote periodontal multi‐tissue regeneration. Therefore, [Si─O4] tetrahedron is a kind of advanced multifunctional metal ion “adjuvants” that can capture metal ions and assist their transmembrane transporting to address metal ion‐induced coagulation interruption and promote multi‐tissue regeneration, providing a new strategy for metal ion‐mediated biotherapy research.

Published: December 2024

AbstractAccurate detection of minute external strains is crucial for the development of efficient strain‐responsive sensors. However, designing a recyclable strain‐responsive sensor that simultaneously combines high sensitivity at low strain levels, excellent mechanical properties, and cost‐effectiveness remains a significant challenge. In this study, a strain‐responsive sensor named Cu2+‐crosslinked conductive acrylic resin (PAV/Cu2+‐CB‐x) has been designed by integrating conductive carbon black (CB) into an acrylic resin matrix crossed by Cu2+ to form a hierarchical dynamic network. Molecular dynamics (MD) simulations reveal that this molecular structure consists of multilevel strong and weak dynamic bonds: weaker coordination bonds and hydrogen bonds endow this sensor with exceptional sensitivity to minor strains, while stronger ionic bonds ensure superior mechanical properties. This meticulous molecular design enables the PAV/Cu2+‐CB‐x to exhibit a tensile strength of 7.16 MPa, an elongation at break of 355.50%, high conductivity of 0.294 S cm−1, and excellent sensitivity under the strains below 5% (gauge factor = 8.24). Additionally, this PAV/Cu2+‐CB‐x demonstrates a remarkable tensile strength recovery rate of 95.35% after multiple recycling. When applied as a strain‐responsive sensor, it can precisely capture movements of human joints and throat activity. This work provides a promising solution for future applications in motion detection and voice recognition.

Published: December 2024

AbstractThe adhesion and proliferation of bacteria on textiles can lead to unacceptable cross‐infection and potential contamination. Herein, an antimicrobial and anti‐adhesive textile is prepared through enzymatic redox‐mediated fabrication of nanosilver‐embedded polydisulfide networks. Specifically, γ‐methacryloyloxypropyltrimethoxysilane is introduced to cotton fibers to build a reactive hydrophobic layer. Subsequently, α‐lipoic acid‐modified tyramine (mTA) is oxidized using horseradish peroxidase and enzymatically grafted onto the vinylated cotton, producing brown polyphenols containing dynamic disulfide bonds. Ultimately, in situ reduction and entrapment of nanosilver are accomplished by the sulfhydryl groups generated from mTA units, forming an antimicrobial network on fiber surfaces. After contact with bacteria for 30 min or fungi for 3 h, the antibacterial rates of the resulting fabric both reach 99.99%. Benefiting from the encouraging photothermal conversion property, bacteria and fungi on fabric surfaces can be killed after 10 min of irradiation at 100 mW cm−2, demonstrating multimode synergistic antibacterial activity. Strikingly, the fabric has impressively durable antimicrobial and bacterial anti‐adhesive properties, maintaining a high bactericidal efficiency after cyclic bacterial contamination tests. Besides, in situ coloring of the fabric is realized while maintaining its inherent wearability, accompanying by satisfactory biocompatibility and hemocompatibility. The presented work provides novel insights into the design and construction of highly efficient antimicrobial textiles.

Published: December 2024

AbstractModification of a surface with polymer brushes has emerged as an effective approach to tune the properties of a substrate. Brushes grown from an inimer‐containing cross‐linkable polymer coating provide significant advantages compared to other “grafting‐from” methods, such as improved stability, increased grafting density, and the potential to control the grafting density. So far, the inimer coating method has only been applied for surface‐initiated controlled radical polymerizations. In this work, an approach is presented for the fabrication of a stable cross‐linked ultra‐thin polymer coating containing hydroxyl groups which serve as initiating sites for surface‐initiated ring‐opening polymerization (SI‐ROP). The polymers used for the fabrication of the coatings consist of 2‐((tetrahydro‐2H‐pyran‐2‐yl)oxy)ethyl methacrylate (THPEMA), a small fraction of a cross‐linkable unit, and a diluent styrene. Three coatings with varying THPEMA and styrene content are fabricated, and poly(dimethyl siloxane) (PDMS) and poly(caprolactone) (PCL) brushes are grown by SI‐ROP of hexamethylcyclotrisiloxane (D3), and ε‐caprolactone respectively. The brushes are characterized by atomic force microscopy (AFM), X‐ray photoelectron spectroscopy (XPS), static contact angle measurements, ellipsometry and size exclusion chromatography (SEC). The results demonstrate a well‐controlled ROP of D3 and ability to control grafting density by tuning the THPEMA content of the coatings.
