ABSTRACT

Folate is an essential component of many metabolic processes, and folate deficiency is known to cause various disorders. Folate and folic acid, a synthetic and chemically stable form of folate, enriched diet are typically used to overcome this deficiency. Folic acid and folate however, are susceptible to harsh environment and folates enrichment using nanoparticles is an intensively studied strategy in food industry. This review highlights the current methods and types of matrices utilized to develop folic acid/folate carrying nanoparticles. The folic acid/folate loaded nanoparticles prevent cargo degradation during gut absorption and under harsh food processing conditions including, high temperatures, UV light, and autoclaving. The data demonstrates that nanofortifcation of folates using proteins and biopolymers effectively enhances the bioavailability of the cargo. The encapsulation of folic acid in biopolymers by emulsion, spray drying and ionic gelation represent simplistic methods that can be easily scaled up with applications in food industry.

ABSTRACT

BACKGROUND: There is an ongoing increase in the demand for injectable procedures and an increase in the number of medical spas across the United States State regulations significantly vary regarding level of supervision at these medical spas. OBJECTIVE: The aim of this study was to determine who performs cosmetic procedures, provides medical supervision, and who is being informed of complications. METHODS: Descriptive study based on a standardized telephone interview performed by a prospective patient for injectable treatments performed at medical Spas in Las Vegas. Data were then extracted and analyzed. RESULTS: Of 63 medical spas reviewed, most of the injectable treatments (73%) were performed by nonphysicians. An onsite physician who supervised or personally performed the cosmetic procedures was present in only 38.1% of the spas surveyed. Only 46% of surveyed medical spas notify a medical director/supervising physician in the event of a complication and only 39.7% of surveyed spas had a number to call after regular business hours. CONCLUSION: The majority of treatments are performed by nonphysicians in the spas surveyed. Physician supervisors are not on site in most of the spas and about half of spas do not inform the medical director in the event of a complication.

ABSTRACT

Cancer cells utilize glucose as their primary energy source. The aggressive nature of cancer cells is therefore enhanced in hyperglycemic conditions. This study has been adopted to investigate the therapeutic potential of melatonin against such aggressive proliferation of AGS cells-a human gastric cancer cell line, under hyperglycemic conditions. AGS cells were incubated with high glucose-containing media, and the effects of melatonin have been evaluated, therein. Cell proliferation, ROS generation, flow-cytometric analysis for cell cycle and apoptosis, wound healing, immunoblotting, zymography, reverse zymography assays, in-silico analysis, and kinase activity assays were performed to evaluate the effects of melatonin. We observed that melatonin inhibited the hyperglycemia-induced cell proliferation in a dose-dependent manner. It further altered the expression and activity of MMP-9 and TIMP-1. Moreover, melatonin inhibited AGS cell proliferation by arresting AGS cells in the G0/G1 phase after binding in the ATP binding site of CDK-2, thereby inhibiting its kinase activity. In association, a significant decrease in the expression of cyclin D1, cyclin E, CDK-4, and CDK-2 were observed. In conclusion, these findings suggest that melatonin has anti-gastric cancer potential. Melatonin could therefore be included in future drug designs for gastric cancer-hyperglycemia co-morbidity treatment.

ABSTRACT

The position of chief resident involves increased leadership, mentorship, and management responsibilities. There is no standardized procedure in which dermatology chief residents are trained and prepared for their final year of residency. In 2008, an annual Dermatology Chief Academy conference was initiated in which incoming chief residents were given formal leadership training for their new role. At the 2020 conference, residents completed a survey regarding their expectations and experience of this conference. After the conference, residents felt significantly better prepared for their new role as chief residents, handling conflicts, and effective leadership. A formal leadership conference for incoming chief residents is vital for improving the success of a residency program.

ABSTRACT

It has long been difficult to treat vulvovaginal laxity, genitourinary syndrome of menopause, stress urine incontinence, overactive bladder (OAB), and other indications of sexual dysfunction because women traditionally find it difficult to discuss these difficulties with clinicians and because society generally accepts these diseases. Originating in esthetic medicine, noninvasive feminine rejuvenation that targets vaginal tissue with energy-based methods has recently become more popular. A more youthful-looking vulva, the restoration of vaginal elasticity and "tightness," a significant improvement in stress urinary incontinence, a reduction in symptoms of OAB, and a decrease in sexual dysfunction are all benefits of transcutaneous temperature-controlled radiofrequency (TTCRF) therapy at the vulvovaginal region. It is also becoming more popular as a mild-to-moderate stress urinary incontinence and OAB noninvasive therapy option. Women will likely always be appreciative of their gynecologist for managing stress urinary incontinence with TTCRF therapy without making an incision, it would appear.

ABSTRACT

Background Infertility and problems of impaired fecundity have been a concern through the ages and are also considerable clinical problems today, affecting many couples worldwide. Most infertility cases are primarily attributed to male factors, which play a significant role. Additionally, a substantial number of these patients exhibit suboptimal sperm parameters. The study is mainly designed for individual intervention and outcome. We aim to evaluate the demographics, etiology, utilization of treatments, and outcomes of males undergoing infertility treatment. Methodology We retrospectively enrolled infertile couples from January 2021 to March 2023, covering the past two years. All patients were evaluated and investigated per the study protocol to identify the cause of infertility. Results Two thousand three hundred forty-eight males were enrolled in the study, of whom 1,484 (63%) were found to have a standard semen analysis. A total of 868 (37%) had abnormal semen parameters. Two hundred and seventy-two (12%) patients completed the evaluation. All parameters, except for hypospermia, displayed lower percentages of motility compared to normozospermia. All semen parameters, except for hypospermia, showed a significantly lower normal morphology in comparison to normozospermia. This reduction increased by 10% for each year of age increment. Conclusions The study concluded by following a protocol for evaluating male patients. If an abnormal sperm parameter is identified before considering intracytoplasmic sperm injection (ICSI), it is recommended to conduct at least karyotyping and microdeletion analysis on the Y-chromosome's q arm.

ABSTRACT

BACKGROUND: The degree of supervision and level of expertise required for performing cosmetic procedures differs significantly from state to state. Medical spas providing cosmetic procedures have seen exponential growth since 2020. OBJECTIVE: To provide a representative sample of the medical spa industry in the Unites States regarding the expertise among providers performing cosmetic procedures and the degree of oversight at medical spas offering these procedures. MATERIALS AND METHOD: Descriptive study based on a standardized telephone interview performed by a secret shopper in Chicago and surrounding suburbs. Data were then extracted and analyzed. RESULTS: Of 127 medical spas reviewed, a supervising physician was not on-site at 81.1% of the facilities. Patients were informed of this at 64.6% of the surveyed medical spas. CONCLUSION: There is considerable variation in the oversight and in the training among those performing cosmetic procedures at surveyed medical spas. As cosmetic procedures become increasingly popular among the public, further regulation of medical spas is warranted to protect patient safety.

ABSTRACT

Rearranged X chromosomes in Turner syndrome (TS) generally present with a mild phenotype, but in cases of ring X chromosomes, the incidence of intellectual disability and other congenital abnormalities can be significantly higher depending on the size of the ring and the involvement of X-inactive specific transcript (XIST) region. Here, we report a 17-year-old female who was referred for a cytogenetic analysis because of primary amenorrhoea. The patient, of normal intelligence, had been found to have traits of TS, especially short stature and some rare findings such as horseshoe kidney and short fourth toe. Cytogenetic analysis showed a mosaic 45, X/46, X and r(X) karyotype. Fluorescence in situ hybridisation analysis using sex chromosome probes permitted us to identify the marker as a ring X chromosome, detected in 30% of cells. The r(X) might include the XIST locus, which would have caused X-inactivation of this abnormal ring chromosome leading to mild phenotype in our patient but with atypical features present in the form of horseshoe kidney and short fourth toe.

ABSTRACT

Background: Stress urinary incontinence (SUI) could be due to urethral hypermobility due to the weakening of the pelvic floor muscles which support the urethra and bladder or the intrinsic sphincter deficiency. The mid-urethral tape acts as an anchored pubo-urethral neo-ligament thus increasing the level of mid-urethral support. The purpose of this study is to evaluate the safety and efficacy of transobturator tape (TOT) for SUI at 5 years of follow-up. Materials and Methods: This was a retrospective observational single-arm study of 40 patients. Ten patients were lost to follow-up; hence, only 30 patients were included in the study. Patients who underwent TOT from 2010 to 2012 were followed up till December 2017. Patients were evaluated for early and late postoperative complications and efficacy of the tape at 5 years. Results: The mean age of the patients with SUI was 48.07 (standard deviation ± 9.38). About 76.66% (n = 23) of patients had only pure stress incontinence, whereas 23.3% of patients (n = 7) had mixed urinary incontinence (MUI). The cure rate in our study was 93.33% at 5 years. Out of the seven patients with MUI, urge incontinence was cured in 71.42% (n = 5). De novo urgency was observed in 6.6% (n = 2). No major complications such as bladder and bowel perforation, vascular hemorrhage, or mesh erosion were seen. Patient satisfaction was graded as excellent in 46.66% (n = 14), good in 30% (n = 9), and poor in 23% (n = 7). Conclusion: TOT for stress incontinence has a high cure rate and very good efficacy at 5 years. No major complications are seen when the procedure is performed by expert hands.

ABSTRACT

OBJECTIVES: India ranks third globally in organ procurement and transplant and has the second highest COVID-19 incidence rate, but data regarding COVID-19 vaccination in solid-organ transplant patients are scarce. MATERIALS AND METHODS: We created a cross-sectional, anonymous, online questionnaire and sentinvitations to several transplant centers in India. We surveyed vaccine mandates, immunization coverage and side effects, administration timing, infection severity among solid-organ transplant recipients, and booster dosage recommendations. RESULTS: The survey results showedthat vaccinepolicy is heterogeneous among centers; vaccination is voluntary at some centers (44.7%), but some centers have established COVID-19 vaccination as a requirement for transplant candidates (44.6%). CoviShield was the most common vaccine administered (89.3%), and more than 50% of transplant recipients and donors were fully vaccinated. Survey results showed that the pretransplant wait time after full vaccination (both doses) is 2 to 4 weeks (48.9%), and the optimal time for vaccination after transplant is 3 to 6 months (59.3%). For vaccinated transplant patients, 89.4% of respondents reported an incidence rate for posttransplant breakthrough infection of less than 25%. For unvaccinated patients, 38.3% ofrespondents reported a 25% to 50% incidence rate of posttransplant COVID- 19 infection. Booster doses are recommended at many transplant centers in India, as reported by 89.4% of survey respondents. CONCLUSIONS: The results of the survey suggested that there are no substantial safety concerns Future targets should include increasing efficacy and increasing booster doses of the COVID-19 vaccine.

ABSTRACT

Worldwide, India ranks number 2 and 3 for COVID-19 burden and absolute transplant numbers, respectively. Here, we summarized our single and multicenter Indian studies on solid-organ transplant during the COVID-19 pandemic. During the pandemic, solid-organ transplants declined 40% to 50%. The mortality rate in COVID-19-positive kidney transplant recipients (11.6%) was lower in India compared with the developed world during the first wave and lower compared with maintenance hemodialysis patients (13% to 38%) but significantly higher compared with the nonimmunosuppressed general population (1% to 3%) in India. We contributed to National Organ and Tissue Transplant Organization transplant-related guidelines to increase safety and access to solid-organ transplant. We reported the safety and feasibility of remdesivir (n = 57) and convalescent plasma therapy (n = 10) in kidney transplant recipients. We reported 100% patient and graft survival without any complications related to COVID-19 in a large cohort of kidney transplant recipients who recovered from COVID-19 (n = 372) and a large cohort of kidney transplant recipients of living donors (n = 31) who recovered from COVID-19 without any change in induction and maintenance immunosuppression. COVID-19 disease severity and mortality in the second episode (reoccurring infection) was higher (46%) compared with the first episode (11.6%). There was 4.4% incidence of COVID-19-associated mucormycosis in kidney transplant recipients with mortality of 46% in the second wave. We reported COVID-19 vaccine safety with suboptimal efficacy in kidney transplant recipients and dialysis patients compared with the general population. Our report suggested that transplant with carefully selected COVID-19-recovered donors and patients may be feasible and safe, at least over the short term. Continued research is needed on vaccine efficacy, booster doses, and long-term follow up sequelae.

ABSTRACT

BACKGROUND: We aimed to analyze the humoral and cellular response to standard and booster (additional doses) COVID-19 vaccination in solid organ transplantation (SOT) and the risk factors involved for an impaired response. METHODS: We did a systematic review and meta-analysis of studies published up until January 11, 2022, that reported immunogenicity of COVID-19 vaccine among SOT. The study is registered with PROSPERO, number CRD42022300547. RESULTS: Of the 1527 studies, 112 studies, which involved 15391 SOT and 2844 healthy controls, were included. SOT showed a low humoral response (effect size [ES]: 0.44 [0.40-0.48]) in overall and in control studies (log-Odds-ratio [OR]: -4.46 [-8.10 to -2.35]). The humoral response was highest in liver (ES: 0.67 [0.61-0.74]) followed by heart (ES: 0.45 [0.32-0.59]), kidney (ES: 0.40 [0.36-0.45]), kidney-pancreas (ES: 0.33 [0.13-0.53]), and lung (0.27 [0.17-0.37]). The meta-analysis for standard and booster dose (ES: 0.43 [0.39-0.47] vs. 0.51 [0.43-0.54]) showed a marginal increase of 18% efficacy. SOT with prior infection had higher response (ES: 0.94 [0.92-0.96] vs. ES: 0.40 [0.39-0.41]; p-value < .01). The seroresponse with mRNA-12723 mRNA was highest 0.52 (0.40-0.64). Mycophenolic acid (OR: 1.42 [1.21-1.63]) and Belatacept (OR: 1.89 [1.3-2.49]) had highest risk for nonresponse. SOT had a parallelly decreased cellular response (ES: 0.42 [0.32-0.52]) in overall and control studies (OR: -3.12 [-0.4.12 to -2.13]). INTERPRETATION: Overall, SOT develops a suboptimal response compared to the general population. Immunosuppression including mycophenolic acid, belatacept, and tacrolimus is associated with decreased response. Booster doses increase the immune response, but further upgradation in vaccination strategy for SOT is required.

ABSTRACT

Well-defined polyhedral ZIF-67 metal-organic frameworks (MOFs) are usually synthesized using methanol as solvent. In this work, methanol is replaced with deionized water as a solvent to synthesize ZIF-67 MOFs with unique nanoflake morphology. The ZIF-67 nanoflakes are synthesized directly byin situmethod on reduced graphene oxide (rGO) to obtain ZIF-67/rGO-xprecursors which are further transformed into NiCo-layered double hydroxide nanocomposites (NiCo-LDH/rGO-x,x = 10, 30, 50 and 90 mg of rGO). The NiCo-LDH/rGO-xnanostructured composites are found to be excellent materials for battery type supercapacitor (supercapattery) applications. Among these samples, the NiCo-LDH/rGO-30 composite gives maximum specific capacity of 829 C g-1(1658 F g-1) at a current density of 1 A g-1and high rate capability. The as fabricated 2-electrode symmetric Swagelok deviceNiCo-LDH/rGO-30NiCo-LDH/rGO-30delivered a high energy density of 49.2 Wh kg-1and a power density of 4511 W kg-1, and enabled us to glow red, blue and white LED bulbs using three coin cells. The device can show good capacity retention even after 3000 continuous charge-discharge cycles. The NiCo-LDH/rGO-30 composite,in situderived from ZIF-67 MOF in combination with optimal amount of rGO, is an excellent material to deliver both high energy density and high power density in supercapattery devices.

ABSTRACT

Background: Modern radiotherapy techniques are using advanced algorithms; however, phantoms used for quality assurance have homogeneous density; accordingly, the development of heterogeneous phantom mimicking human body sites is imperative to examine variation between planned and delivered doses. Objective: This study aimed to analyze the accuracy of planned dose by different algorithms using indigenously developed heterogeneous thoracic phantom (HT). Material and Methods: In this experimental study, computed tomography (CT) of HT was done, and the density of different parts was measured. The plan was generated on CT images of HCP with 6 and 15 Megavoltage (MV) photon beams using different treatment techniques, including three-dimensional conformal radiotherapy (3D-CRT), intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT). Plans were delivered by the linear accelerator, and the dose was measured using the ion chamber (IC) placed in HT; planned and measured doses were compared. Results: Density patterns for different parts of the fabricated phantom, including rib, spine, scapula, lung, chest wall, and heart were 1.849, 1.976, 1.983, 0.173, 0.855, and 0.833 g/cc, respectively. Variation between planned and IC estimated doses with the tolerance (±5%) for all photon energies using different techniques. Acuros-XB (AXB) showed a slightly higher variation between computed and IC estimated doses using HCP compared to the analytical anisotropic algorithm (AAA). Conclusion: The indigenous heterogeneous phantom can accurately simulate the dosimetric scenario for different algorithms (AXB or AAA) and be also utilized for routine patient-specific QA.
