Key players of immunosuppression in epithelial malignancies: Tumor-infiltrating myeloid cells and γδ T cells.

BACKGROUND: The tumor microenvironment of solid tumors governs the differentiation of otherwise non-immunosuppressive macrophages and gamma delta (γδ) T cells into strong immunosuppressors while promoting suppressive abilities of known immunosuppressors such as myeloid-derived suppressor cells (MDSCs) upon infiltration into the tumor beds. RECENT FINDINGS: In epithelial malignancies, tumor-associated macrophages (TAMs), precursor monocytic MDSCs (M-MDSCs), and gamma delta (γδ) T cells often acquire strong immunosuppressive abilities that dampen spontaneous immune responses by tumor-infiltrating T cells and B lymphocytes against cancer. Both M-MDSCs and γδ T cells have been associated with worse prognosis for multiple epithelial cancers. CONCLUSION: Here we discuss recent discoveries on how tumor-associated macrophages and precursor M-MDSCs as well as tumor associated-γδ T cells acquire immunosuppressive abilities in the tumor beds, promote cancer metastasis, and perspectives on how possible novel interventions could restore the effective adaptive immune responses in epithelial cancers.

Residue behavior and consumer risk assessment of spirotetramat and chlorpyrifos on cabbage heads and cropped soil.

A field experiment following good agricultural practices was laid out to study the dissipation of spirotetramat (90 g a.i. ha-1 and 180 g a.i. ha-1) and chlorpyrifos (400 g a.i. ha-1 and 800 g a.i. ha-1) on cabbage heads and soil. Samples were processed using quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for residue estimation of spirotetramat and chlorpyrifos, which were further detected using HPLC-PDA and GC-FPD respectively. The residues of spirotetramat on cabbage heads reached below detection limit (BDL) (< 0.05 mg kg-1) on 7th and 10th day and for chlorpyrifos, BDL (< 0.01 mg kg-1) was achieved on 10th and 15th day for X and 2X dose, respectively. On 20th day after second spray, residues in soil were found to be BDL for both the pesticides. Half-life of spirotetramat and chlorpyrifos was found to be 3 and 2 days, respectively while a safe pre-harvest interval (PHI) of 9 days for spirotetramat and 10 days for chlorpyrifos is suggested on cabbage. The dietary risk assessment studies for various age groups of Indian population, ascertained safety of treated cabbage heads for consumption, as current study revealed that hazard quotient (HQ) < 1 and theoretical maximum dietary intake (TMDI) < maximum permissible intake (MPI) for both the pesticides at respective PHI.

Effect of salt pretreatments on physico-chemical, cooking and rehydration kinetics of instant rice.

Instant rice is well-suited for ready-to-use applications as low-moisture, light-weight military ration and emergency food for our Armed Forces, offering longer shelf life with rapid rehydration characteristics. Present investigation demonstrated the effect of different salt pretreatment during soaking as precooking operation on the physico-chemical, cooking and rehydration kinetics of instant rice. Application of salt pretreatment reduced bulk density and damaged grain percentage, while enhanced the porosity, volume expansion percent, weight gain percentage, and rehydration characteristics. The grain elongation ratio was not affected significantly by the application of salt pretreatments; however, water uptake and chemical composition were significantly affected. Soaking pretreatment with 1% calcium chloride, followed by open pan cooking and subsequently freeze-thaw-dehydrating until attainment of 5-6% moisture content was found to be the optimal processing condition for developing instant rice with less than 2 min of rehydration time by mere addition of hot water. Modelling of water absorption behaviour revealed that both Peleg (R2 0.980-0.999) and Singh and Kulshrestha (R2 0.966-0.999) models fitted well.

Text-Mining and Video Analytics of COVID-19 Narratives Shared by Patients on YouTube.

This study explores how individuals who have experienced COVID-19 share their stories on YouTube, focusing on the nature of information disclosure, public engagement, and emotional impact pertaining to consumer health. Using a dataset of 186 YouTube videos, we used text mining and video analytics techniques to analyze textual transcripts and visual frames to identify themes, emotions, and their relationship with viewer engagement metrics. Findings reveal eight key themes: infection origins, symptoms, treatment, mental well-being, isolation, prevention, government directives, and vaccination. While viewers engaged most with videos about infection origins, treatment, and vaccination, fear and sadness in the text consistently drove views, likes, and comments. Visuals primarily conveyed happiness and sadness, but their influence on engagement varied. This research highlights the crucial role YouTube plays in disseminating COVID-19 patient narratives and suggests its potential for improving health communication strategies. By understanding how emotions and content influence viewer engagement, healthcare professionals and public health officials can tailor their messaging to better connect with the public and address pandemic-related anxieties.

Recent Approaches on Molecular Markers, Treatment and Novel Drug Delivery System Used for the Management of Colorectal Cancer: A Comprehensive Review.

Colorectal cancer affects 1 in 25 females and 1 in 24 males, making it the third most frequent cancer with over 6,08,030 deaths worldwide, despite advancements in detection and treatments, including surgery, chemotherapeutics, radiotherapy, and immune therapeutics. Novel potential agents have increased survival in acute and chronic disease conditions, with a higher risk of side effects and cost. However, metastatic disease has an insignificant long-term diagnosis, and significant challenges remain due to last-stage diagnosis and treatment failure. Early detection, survival, and treatment efficacy are all improved by biomarkers. The advancement of cancer biomarkers' molecular pathology and genomics during the last three decades has improved therapy. Clinically useful prognostic biomarkers assist clinical judgment, for example, by predicting the success of EGFR-inhibiting antibodies in the presence of KRAS gene mutations. Few biomarkers are currently used in clinical settings, so further research is still needed. Nanocarriers, with materials like Carbon nanotubes and gold nanoparticles, provide targeted CRC drug delivery and diagnostics. Light-responsive drugs with gold and silica nanoparticles effectively target and destroy CRC cells. We evaluate the potential use of the long non-coding RNA (non-coding RNA) oncogene plasmacytoma variant translocation 1 (PVT1) as a diagnostic, prognostic, and therapeutic biomarker, along with the latest nanotech breakthroughs in CRC diagnosis and treatment.

Fahr Syndrome Secondary to Pseudohypoparathyroidism.

Fahr syndrome is a rare neurologic disorder, usually affecting young and middle-aged adults, that can present with symptoms ranging from extrapyramidal to neuropsychiatric abnormalities. Pseudohypoparathyroidism (PHP), characterized by parathyroid hormone (PTH)-resistance or PTH-unresponsiveness at target organs, is associated with Fahr syndrome and typically presents with hypocalcemia. The following case presents a 39-year-old-woman with PHP complicated by symptomatic hypocalcemia, hypokalemia, and movement disturbances, who had computed tomography imaging showing basal ganglia calcifications consistent with Fahr syndrome. She initially presented with headache and was hospitalized for hypertensive emergency and severe hypocalcemia. Examination, including the neurologic examination, was unrevealing aside from hypertension and central adiposity. Laboratory tests were consistent with PHP, showing hypocalcemia with elevated PTH, and negative for hyperaldosteronism. Management of hypocalcemia consisted of intravenous calcium infusion, oral calcium carbonate, oral vitamin D3, and oral calcitriol. Patients with severe hypocalcemia and elevated PTH who present with new neurological symptoms despite normal general neurologic examination may warrant consideration for brain imaging to evaluate for Fahr syndrome. Further investigations are necessary to determine the prevalence of Fahr syndrome and hypokalemia in patients with PHP, explore if these findings are significantly associated with PHP-1b subtype, and ultimately inform potential new screening pathways for these patients.

Association of the CDH13 gene variant rs9940180 with schizophrenia risk in North Indian population.

BACKGROUND AND OBJECTIVES: Cadherin13 (CDH13) is an uncommon cadherin family member, lacking a transmembrane domain, and attaches via a glycosylphosphatidylinositol anchor to the peripheral surface of the cell membrane. CDH13 plays an important role in the development and maintenance of axonal growth cones, synapse morphogenesis, and the embryonic neural tube. Cadherin superfamily genes have been associated with many neuropsychiatric diseases. Studies have shown the Cadherin13 gene as a risk locus for Schizophrenia (SCZ). In this study, we investigated CDH13 gene variants rs7204454 in the promotor region and rs9940180 in the intronic region of the gene with susceptibility to SCZ risk in the population of Jammu region of J&K, India. METHODS: The genotyping was performed using TaqMan assay, where 560 individuals, comprising 164 patients and 396 healthy controls, were genotyped. RESULTS: The result of the study suggested rs9940180 was significantly found to be associated with Schizophrenia and the "C" allele of rs9940180 was associated with increased risk for SCZ (P = 0.03817; OR = 1.527; 95% CI, 1.022-2.28) whereas the other variant rs7204454 of CDH13 gene did not show significant association with schizophrenia risk with P = 0.8827, OR = 0.582-1.33 at 95% CI. CONCLUSION: This is the first report suggesting a significant association of polymorphism at CDH13 rs9940180 with Schizophrenia in the Dogra population group of the Jammu region. The current study offers a piece of important information on the genetic reason for CDH13 in the Jammu population of J&K. Also, it supports the GWAS findings on the correlation of CDH13 in schizophrenia.

Residue behaviour and health risk assessment of chlorpyrifos and mancozeb in apple fruits and soil.

Mancozeb residue estimation was done using second derivative ultraviolet spectroscopy by Shimadzu ultraviolet-visible spectrophotometer, and chlorpyrifos was estimated by QuEChERS technique using GC-FPD. The persistence for chlorpyrifos was carried out at two locations, and for mancozeb, persistence studies were carried out at four locations. Initial deposits of mancozeb on apple fruits ranged from 1.33 to 1.63 mg/kg at the recommended dose and from 2.55 to 3.26 mg/kg at double the recommended dose at all four locations. Chlorpyrifos residues in apple fruits had an initial deposit of 0.94-0.99 mg/kg at recommended dose and 1.75-1.92 mg/kg at double the recommended dose. Mancozeb residues in apple fruit were below the detection limit (BDL) after 20 days at recommended dose and after 25 days at double the recommended dose at two locations, while mancozeb residue at the other two locations and the residues of chlorpyrifos at all locations reached BDL after 15 and 20 days at recommended and double the recommended doses, respectively. Half-life of mancozeb varied from 3.07 to 4.02 days at recommended dose and from 3.30 to 4.32 days at double the recommended dose, whereas chlorpyrifos residues dissipated to half their initial concentration on 2.33-2.35 days at recommended dose and 2.89-2.90 days at double the recommended dose. The soil samples showed no presence of residues of chlorpyrifos and mancozeb at harvest. The risk assessment revealed that hazard quotient for the intake of mancozeb was in the range of 0.06-0.13% and 0.20-0.44% for rural and urban population, while for the intake of chlorpyrifos, hazard quotient was in the range of 0.10-0.12% for rural population and 0.33-0.38% for urban population, and theoretical maximum dietary intake (9.67 × 10-5 mg/person and 3.18 × 10-4 mg/person for rural population and urban population in case of mancozeb and 3.22 × 10-5 mg/person and 1.06 × 10-4 mg/person for rural population and urban population in case of chlorpyrifos) was also found to be less than maximum permissible intake (1.38 mg/kg for mancozeb and 0.60 mg/kg for chlorpyrifos). The results of risk assessment thereby indicated that apple consumption does not pose a risk to human health.

Immature Teratoma: A Case Report of a Monster Tumor in the Pediatric Age Group.

Immature teratoma is a rare type of germ cell tumor containing embryonic tissues that may be malignant. It usually occurs in young women and affects the ovaries. Teratomas exhibit benign clinical behavior, but they can return as teratomas or with malignant components, and in a small subset of individuals, the prognosis may be deadly. We will discuss a case of a 9-year-old female child who presented with pain and a huge lump in the lower abdomen that was suggestive of an ovarian dermoid cyst or a germ cell tumor on computed tomography (CT) abdomen pelvis and underwent exploratory laparotomy and debulking surgery. Histopathology results indicated that she had a grade 3 immature teratoma. Postoperatively, the patient received 3 cycles of bleomycin, etoposide, and cisplatin (BEP) as adjuvant chemotherapy with a good response. She is currently under regular follow-up and has no evidence of recurrence or metastasis. This case illustrates the importance of early diagnosis and treatment of immature teratoma, which can be cured with surgery and chemotherapy. It also highlights the challenges of managing such a large tumor in a pediatric patient.

Placental Abruption Complicated by the Couvelaire Uterus: A High-Risk Obstetric Case at 30 Weeks Gestation.

Placental abruption, a rare but life-threatening obstetric emergency, presents substantial risks to maternal and fetal well-being. This case report documents the clinical journey of a 35-year-old woman with multiple risk factors who presented at 30 weeks gestation with symptoms suggestive of placental abruption, including colicky lower abdominal pain and vaginal bleeding. Notably, her late initiation of prenatal care and a history of pregnancy-induced hypertension added complexity to the clinical picture. The case revealed a Couvelaire uterus, an uncommon and challenging complication of placental abruption, further emphasizing the need for early recognition and swift intervention. A multidisciplinary approach played a pivotal role in managing this high-risk obstetric case. Imaging and laboratory tests facilitated diagnosis and assessment, guiding surgical intervention and post-operative care. Despite the severity of the condition, the patient experienced a positive outcome for herself and her fetus, highlighting the critical importance of timely and comprehensive medical care. This case report contributes to medical knowledge by shedding light on the rare Couvelaire uterus. It underscores the significance of early diagnosis, coordinated healthcare teams, and patient education in mitigating risks associated with placental abruption. Ultimately, it reinforces the vital role of healthcare providers in safeguarding the lives of expectant mothers and their infants in obstetric emergencies.

Glycerosomes: Novel Nano-Vesicles for Efficient Delivery of Therapeutics.

BACKGROUND: The topical drug delivery system has gained more attention in recent years as compared to oral and parenteral drug delivery. However, owing to the barrier function of the skin's topmost layer, only a few drug molecules can be administered by this route. Therefore, encapsulating the drugs in glycerosomes is one potential solution to this problem. Glycerosomes are vesicular drug delivery systems primarily made up of large concentrations of glycerol, phospholipid, water, and other active ingredients. OBJECTIVE: The main aim of this review is to summarize the most recent information on the encapsulated vesicular system used in cosmetic preparations, specifically glycerosomes made from both synthetic and naturally occurring plant bioactive substances. PURPOSE: Glycerosomes offer many benefits, including increased efficacy, better stability, improve absorption, drug targeting at specific sites, and delivering the same at a predetermined rate. METHOD: The mechanism behind the penetration of glycerosomes is the hydration and lipid fluidization of skin, fabricated by glycerol. RESULT: Numerous methods have been reported for the formulation of glycerosomes, including the thin film hydration method, reverse-phase evaporation, solvent spherule, detergent removal method, and so on. CONCLUSION: Researchers are currently investigating the potential of glycerosomes as nanocarriers for natural bioactive and synthetic drugs. This review describes the structure of glycerosomes, preparation techniques, applications, distinctions from liposomes, and benefits of glycerosomes.

Groundwater hydrogeochemistry and non-carcinogenic health risk assessment in major river basins of Punjab, India.

The Indian Punjab state is drained by the four rivers, along with a well-connected network of canals, and is now dealing with a slew of water quality issues and problems. In this study, basin-wise hydrogeochemical modelling of 323 groundwater samples and identification of NO3- and F- enrichment pathways in aquifer systems of Punjab were studied using different plots and multivariate statistics. To evaluate the groundwater quality and human health risks, an entropy-based water quality index and Monte Carlo simulation were used, respectively. Spatial distribution of NO3- indicated that its very high values were prominent in parts of southwestern Punjab falling under LSRB, along with few pockets in eastern and northeastern Punjab falling under MSRB and GRB. High NO3- values (> 45.0 mg/L) were found in 15.0% of Ravi River Basin (RRB) groundwater samples, 22.86% of Beas River Basin (BRB), 23.52% of Middle Sutlej River Basin (MSRB), 36.9% of Lower Sutlej River Basin (LSRB), and 21.31% of Ghaggar River Basin (GRB). The spatial distribution of NO3- revealed elevated concentrations (> 100 mg/L) in the southwestern part of Punjab, particularly in LSRB and localized pockets in the eastern and northeastern areas of Punjab within MSRB and GRB. High F- concentration (> 1.5 mg/L) was observed in 15.12% and 21.31% groundwater samples of LSRB and GRB, respectively. Spatially southern parts falling under LSRB and GRB reflected high F- content (> 1.5 mg/L) in groundwater. In LSRB, evaporative and anthropogenic processes influence the groundwater quality. The results of interionic relationships and statistical analysis revealed that NO3- has anthropogenic origin and that is being aggravated by leaching, the evaporation processes, animal excreta, septic tanks and irrigation return flows in LSRB and GRB, while F- is geogenic in nature. Hazard index (HI) values in 14.63%, 22.2%, 24.6%, 49.58%, and 34.42% samples for adults and 21.95%, 27.7%, 42.0%, 72.3%, and 52.46% samples for children were higher than unity in RRB, BRB, MSRB, LSRB, and GRB, respectively. The basin-wise demarcation of various groundwater quality parameter and assessment of human health risk would be of significance for the management of water resources.

Healthcare professionals' perspectives of the provision of, and challenges for, eating, drinking and psychological support post stroke: findings from semistructured interviews across India.

AIM: This qualitative study explores with health professionals the provision of, and challenges for, postdischarge stroke care, focussing on eating, drinking and psychological support across India. DESIGN: Qualitative semistructured interviews. SETTING: Seven geographically diverse hospitals taking part in a Global Health Research Programme on Improving Stroke Care in India. PARTICIPANTS: A purposive sample of healthcare professionals with current experience of working with patients who had a stroke. RESULTS: Interviews with 66 healthcare professionals (23 nurses (14 staff nurses; 7 senior nurse officers; 1 intensive care unit nurse; 1 palliative care nurse)); 16 doctors (10 neurologists; 6 physicians); 10 physiotherapists; 5 speech and language therapists; 4 occupational therapists; 4 dieticians; 2 psychiatrists; and 2 social workers resulted in three main themes: integrated inpatient discharge care planning processes; postdischarge patient and caregiver role and challenges; patient and caregiver engagement post discharge. CONCLUSIONS: Discharge planning was integrated and customised, although resources were limited in some sites. Task shifting compensated for a lack of specialists but was limited by staff education and training. Caregivers faced challenges in accessing and providing postdischarge care. Postdischarge care was mainly hospital based, supported by teleservices, especially for rural populations. Further research is needed to understand postdischarge care provision and the needs of stroke survivors and their caregivers.

Telephonic intervention to combat non-adherence to oral iron-folic acid supplementation in pregnancy: A randomized controlled trial.

Introduction: Iron deficiency anemia is a public health problem globally attributing to high incidences of maternal and infant mortality and morbidity. Iron and folic acid supplementation (IFAS) is essential and provided free of cost by the public health sectors, however, a systematic review shows that the national-level adherence to oral Iron-Folic Acid Supplementation (IFAS) is less than half in pregnant women, and the significant obstacles to non-adherence are fear of side effects and forgetfulness. This trial was designed to mitigate the side effects and tackle forgetfulness with telephonic intervention. The objectives were to investigate the effectiveness of the telephonic intervention on oral IFAS adherence and hemoglobin and the reasons for non-adherence to oral IFAS, to find out the proportion of anemia in the study population, and to assess the effectiveness of the intervention on maternal and neonatal outcomes. Methods: Hospital-based open-label multi-centric parallel-group randomized controlled trial, used block randomization and allocated treatment in a 1:1 ratio recruited 286 anemic pregnant women between 14 and 24 weeks of gestation with hemoglobin level < 11 g/dl having smartphones at a secondary hospital and a tertiary hospital in Eastern India. The experimental group received telephonic intervention for one month via structured text reminders, WhatsApp audio messages, and phone calls. The standard course of treatment was given to the control group. Results: 286 women (n1 =143, n2 =143) were randomized, 36 had attrition leaving 250 for analysis (n1 =123, n2 =127), the experimental group experienced a 44.9 % and the control group 13.8 % increase in adherence (P < 0.001). The leading reasons for non-adherence were forgetfulness (24 %), nausea and vomiting (23.2 %), and constipation (18.8 %). Hemoglobin level increased by 0.8 g/dl (P < 0.001) in the experimental group and 0.2 g/dl (P < 0.807) in the control group. Conclusion: In addition to improving adherence to oral IFAS, telephonic intervention mitigates side effects and enhances hemoglobin in anemic pregnant women. The increase in adherence was threefold in the experimental group compared to a marginal rise in the control group. This study recommends the implementation of a telephonic intervention to promote adherence to oral IFAS among anemic pregnant women.

Pre-Conceptional and Antenatal Care for Improved Newborn and Child Survival in India: A Review.

There is sufficient scientific evidence that quality pre-conceptional care and antenatal care can improve newborn survival. This review was conducted to understand the concept of pre-conceptional care and its implementation status in India. The review documents the specific interventions that have been proven to effectively improve pregnancy outcome when provided as pre-conception care. Healthcare providers, particularly obstetricians/gynecologists and general physicians, should prioritize pre-conception care as an essential component of healthcare for women. However, the lack of continuum of care and program linkages are some of the key barriers in ensuring pre-conceptional and ante-natal care in India. Culturally and linguistically appropriate care should be provided to ensure that all women can access and understand the information and services needed to optimize their reproductive health and improve pregnancy outcomes. Prioritizing pre-conception and prenatal care, healthcare providers can improve maternal and fetal outcomes, reduce healthcare costs, and promote lifelong health for women and their families. The primary healthcare reforms being done in India can be and should be used to strengthen pre-conceptional and ante-natal care services and quality.

Metatranscriptomic insight into the possible role of clay microbiome in skin disease management.

Even though the scientific documentation is limited, microbiome of healing clay is gradually gaining attention of the scientific community, as a therapeutic force playing an indispensable role in skin disease management. The present study explores the metatranscriptome profile of the Chamliyal clay, widely known for its efficacy in managing various skin problems, using Illumina NextSeq sequencing technology. The gene expression profile of the clay microbial community was analyzed through SEED subsystems of the MG-RAST server. Due to the unavailability of metatranscriptomic data on other therapeutic clays, Chamliyal's profile was compared to non-therapeutic soils, as well as healthy and diseased human skin microbiomes. The study identified Firmicutes, Proteobacteria, and Actinobacteria as the primary active microbial phyla in Chamliyal clay. These resemble those abundant in a healthy human skin microbiome. This is significant as lower levels of these phyla in the skin are linked to inflammatory skin conditions like psoriasis. Interestingly, pathogenic microbes actively metabolizing in the clay were absent. Importantly, 6% of the transcripts annotated to sulfur and iron metabolism, which are known to play a major role in skin disease management. This study provides the most comprehensive and a novel overview of the metatranscriptome of any of the healing clay available worldwide. The findings offer valuable insights into the clay microbiome's potential in managing skin disorders, inspiring future endeavors to harness these insights for medical applications.

Unicornuate Uterus with a Non-Communicating Rudimentary Horn: Challenges and Management of a Rare Pregnancy.

We present a unique case of pregnancy developed in a unicornuate uterus with a non-communicating rudimentary horn, emphasizing the importance of early identification, careful management, and counseling. Our patient, a 28-year-old woman, presented with abdominal pain and premature rupture of membranes at 37 weeks of gestation. She had a history of one previous normal vaginal delivery and no significant medical or genetic factors. An emergency cesarean section was performed, and a baby boy weighing 2900 grams was delivered without complications. The uterine anomaly was identified as a unicornuate uterus with a non-communicating rudimentary horn. This case report highlights the challenges and risks associated with unicornuate pregnancies, such as fetal growth restriction and preterm labor. Timely identification, meticulous monitoring, and comprehensive counseling are crucial for optimal outcomes in such cases. Further research and larger-scale studies are needed to enhance our understanding of these rare and complex pregnancies.

Apremilast Add-On Benefits Over Conventional Drugs (ABCD) in Unstable Non-segmental Vitiligo: A 12-Week Single-Center Randomized Controlled Trial.

Background Apremilast is an oral phosphodiesterase-4 enzyme inhibitor that modulates the immune system by increasing intracellular cyclic adenosine monophosphate levels and inhibiting inflammatory cytokines synthesis. We aimed to compare the efficacy and safety of add-on apremilast in combination therapy with standard treatment in patients with unstable, non-segmental vitiligo. Methods The study was a 12-week randomized, controlled, parallel-group, open-labeled trial. The control group received standard treatment (n=15), and the intervention group received 30 mg apremilast twice daily in addition to standard treatment (n= 16). Time to the first sign of re-pigmentation, halt in progression, and change in vitiligo area scoring index (VASI) score is the primary outcomes. Normality was assessed, and appropriate parametric and nonparametric tests were undertaken. Results Thirty-seven participants were randomized into two groups, and analysis was done on thirty-one participants. Over the treatment duration of 12 weeks, the median time to observe the first sign of re-pigmentation was four weeks in the add-on apremilast group compared to seven weeks in the control group (p=0.018). The halt in progression was observed more in the add-on Apremilast group (93.75%) compared to the control group (66.66%) (p=0.08). The VASI score decreased by 1.24 in the add-on apremilast group and 0.05 in the control group (p= 0.754). Parameters including body surface area, dermatology life quality index, and body mass index reduced significantly, while the visual analog scale increased significantly in the add-on apremilast group. However, results were comparable between groups. Conclusions Treatment with add-on apremilast accelerated clinical improvement. It also reduced disease progression and improved the disease index among participants. However, add-on apremilast had a lower tolerability profile than the control group.

Role of Nanomedicines in Controlling Malaria: A Review.

Malaria has created havoc since time immemorial. It has actually become a major health concern due to its high prevalence in developing countries where poor sanitary conditions facilitate the seasonal breeding of the vector, the female Anopheles mosquito. Even after tremendous advancements in pest control and pharmacology science, managing this disease has not been successful, and the cure for this deadly infection has not proven effective lately. The various conventional drugs used are chloroquine, primaquine, mefloquine, atovaquone, quinine, artemisinin etc. All of these have one or other major disadvantages like multi-drug resistance, high dose requirements, aggravated toxicity, non-specificity of conventional drugs, and the emergence of drug-resistant parasites. Therefore, it is necessary to surpass these limitations and look for an alternative to curb the spread of this disease using an emerging technology platform. Nanomedicine is showing promise as an effective alternative tool for the management of malaria. The idea of this tool resonates well with David J. Triggle's outstanding suggestion "The chemist is as the astronaut, searching for biologically useful space in the chemical universe. This review presents a detailed discussion on various nanocarriers, their mode of action and future perspective in treating malaria. Nanotechnology-based drug delivery methods are highly specific, require a lower dose, offer more bioavailability with prolonged drug release and stay in the body longer. Recent nano drug encapsulation and delivery vehicles comprise nanocarriers like liposomes, and organic and inorganic nanoparticles, emerging as promising alternatives for malaria management.

Yttrium Oxide Nanoparticle-Loaded, Self-Assembled Peptide Gel with Antibacterial, Anti-Inflammatory, and Proangiogenic Properties for Wound Healing.

Chronic wounds are a major healthcare challenge owing to their complex healing mechanism and number of impediments to the healing process, like infections, unregulated inflammation, impaired cellular functions, poor angiogenesis, and enhanced protease activity. Current topical care strategies, such as surgical debridement, absorption of exudates, drug-loaded hydrogels for infection and inflammation management, and exogenous supply of growth factors for angiogenesis and cell proliferation, slow the progression of wounds and reduce patient suffering but suffer from low overall cure rates. Therefore, we have developed a proteolytically stable, multifunctional nanoparticle loaded-peptide gel with inherent anti-inflammatory, antibacterial, and pro-angiogenic properties to provide a favorable wound healing milieu by restoring impaired cellular functions. We have fabricated a self-assembled, lauric acid-peptide conjugate gel, LA-LLys-DPhe-LLys-NH2, loaded with yttrium oxide (Y2O3) nanoparticles (NLG). Gel formed a nanofibrous structure, and nanoparticles were passively entrapped within the network. The surface morphology, stability, viscoelastic, and self-healing characteristics of gels were characterized. It showed a high stability against degradation by proteolytic enzymes and highly potent antibacterial activities against E. coli and S. aureus due to the presence of positively charged side chains of lysine in the peptide chain. It also exhibited an excellent antioxidant activity as well as ability to stimulate cell proliferation in murine fibroblast (L929) cells and human umbilical vein endothelial cells (HUVECs). The incorporation of nanoparticles promoted angiogenesis by upregulating pro-angiogenic genes, vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF2), and epidermal growth factor (EGFR), and the gel caused complete wound closure in cells. In summary, the Y2O3 nanoparticle-loaded lauric acid-peptide conjugate gel is able to elicit the desired tissue regeneration responses and, therefore, has a strong potential as a matrix for the treatment of chronic wounds.
