The liver, a pivotal organ in human metabolism, serves as a primary site for heme biosynthesis, alongside bone marrow. Maintaining precise control over heme production is paramount in healthy livers to meet high metabolic demands while averting potential toxicity from intermediate metabolites, notably protoporphyrin IX. Intriguingly, our recent research uncovers a disrupted heme biosynthesis process termed ‘porphyrin overdrive’ in cancers that fosters the accumulation of heme intermediates, potentially bolstering tumor survival. Here, we investigate heme and porphyrin metabolism in both healthy and oncogenic human livers, utilizing primary human liver transcriptomics and single-cell RNA sequencing (scRNAseq). Our investigations unveil robust gene expression patterns in heme biosynthesis in healthy livers, supporting electron transport chain (ETC) and cytochrome P450 function without intermediate accumulation. Conversely, liver cancers exhibit rewired heme biosynthesis and a massive downregulation of cytochrome P450 gene expression. Notably, despite diminished drug metabolism, gene expression analysis shows that heme supply to the ETC remains largely unaltered or even elevated with patient cancer progression, suggesting a metabolic priority shift. Liver cancers selectively accumulate intermediates, which are absent in normal tissues, implicating their role in disease advancement as inferred by expression analysis. Furthermore, our findings in genomics establish a link between the aberrant gene expression of porphyrin metabolism and inferior overall survival in aggressive cancers, indicating potential targets for clinical therapy development. We provide in vitro proof-of-concept data on targeting porphyrin overdrive with a drug synergy strategy.

Facial nerve injuries pose challenges in cosmetic surgery. We comprehensively reviewed the anatomy of the facial nerve, with a focus on its five major branches—temporal, zygomatic, buccal, marginal mandibular, and cervical— and explored the clinical implications of nerve injuries during cosmetic procedures. Surgical damage to any branch of the facial nerve can lead to functional impairments, including facial asymmetry, impaired eye closure, speech difficulties, and reduced oral competence. Furthermore, aesthetic consequences, including facial drooping and altered appearance, can profoundly affect patients' psychological well-being. This review provides a detailed discussion of strategies for preventing nerve injury, including surgical techniques and landmark identification that underscores the importance of meticulous preoperative planning and intraoperative execution. This review highlights the importance of comprehensive anatomical knowledge in optimizing patient safety and satisfaction in facial cosmetic surgery.

Background: Adolescence is the crucial phase in the woman’s life has on the woman’s health and later on reproductive and maternal life. Around 20% of the global health burden among women is attributed to reproductive and sexual ill health, lack of menstrual hygiene is one of the factors among the adolescent. They lack awareness about menstruation when they first experience it, especially in rural and tribal areas. This study aimed to provide an insight into the most sensitive issue of menstruation among the tribal community which would help in promoting improved awareness level and increase in right knowledge about menstruation. Methods: A cross sectional study. Total of 114 adolescent girls (11-18 years), have attained the menarche were included. Universal sampling method is used. Data was collected regarding their perceptions and practices related to menstrual hygiene. Results: The mean age of the subjects and of menarche were 15.48±1.75, 13.09±1.04 years respectively. About 27.20% had no clue about the menstrual cycle. Majority of them asked their mothers about the problems followed by close friends. About 37.72% used sanitary napkins. Not to attend religious occasion (54.39%) was common restriction. Conclusions: In the present study, it is reflected that mothers of the adolescent girls were a crucial and important role in giving information about menstrual hygiene. More awareness related to hygiene and practice and education related to social issues related to menstrual hygiene has to be addressed. Focussed programmes related to tribal adolescent health have to be implemented.

Background: Islet allotransplantation (ITA) is a surgical approach for treating patients with type 1 diabetes mellitus (T1DM) and severe hypoglycemic unawareness. Surgeons at the University of Minnesota typically perform ITA via mini-laparotomy (MLAP) under monitored anesthesia care (MAC) unless generalized endotracheal anesthesia (GETA) is indicated or needed. Herein, we studied the use of ultrasound-guided transversus abdominis plane (TAP) blocks to optimize perioperative analgesia. Methods: We report the case of a 46-year-old man with a 24-year history of T1DM and recurrent hypoglycemic seizures who underwent two ITA procedures via MLAP with preoperative TAP blocks. To provide more information about the broader impact of TAP blocks, we analyzed the outcomes of 51 MLAP-based ITA procedures. Results: In our case report patient, both procedures were completed without complications. The patient reported minimal postoperative pain, ambulated within 24 h, and was discharged on postoperative days 3 and 2, respectively. The patient remained free from severe hypoglycemia for 10 years, and he only began to require minimal doses of long-acting insulin in the past year. From additional case review, TAP blocks were used in 22% of the cases. The use of TAP blocks did not lead to significant differences in operative duration or length of stay. Conclusions: Although TAP blocks can be used as part of an enhanced recovery after surgery (ERAS) approach, we did not identify any significant advantages of using TAP blocks over field blocks during MLAP-based ITA procedures among patients with T1DM.
