Purpose: Hair disorders, which are often attributed to conditions associated with a shortened anagen growth phase, oxidative stress, and hormonal dysregulation, especially during aging, have profound psychological implications. Currently, only minoxidil has been approved as a topical hair growth solution; thus, alternative therapies for treating hair loss and promoting hair health are urgently needed. Herein, we aimed to develop and assess a novel method to promote hair growth and health using mastic (Pistacia lentiscus) gum and peppermint (Mentha piperita L.) extracts. Materials and Methods: After determining the optimal ratio of mastic gum and peppermint extracts, we performed in vitro and in vivo experiments to verify the efficacy of the 7:3 mastic gum-peppermint mixture (MP73; FHH-MG) for enhancing hair growth and health. Results: Mastic gum significantly promoted cell proliferation and demonstrated synergistic benefits when combined with peppermint extract. In vitro, FHH-MG increased human dermal follicle papilla cell proliferation and demonstrated anti-inflammatory and antioxidant effects. In vivo, treatment with FHH-MG dose-dependently enhanced hair growth and gloss and increased the expression of vascular endothelial growth factor, epidermal growth factor, β-catenin, and insulin-like growth factor-1 in C57BL/6 mice compared to the negative control. Conclusion The novel mixture exhibited hair growth-promoting effects in C57BL/6 mice; thus, FHH-MG may serve as a botanical alternative for hair growth and health promotion.

The global older adult population is rapidly growing, intensifying the burden of elderly care. To alleviate this challenge of an aging society, interventions utilizing artificial intelligence (AI) technology are becoming widespread. This review aimed to examine the effects of AI robot interventions on the psychological outcomes of community-dwelling older adults through a systematic literature review. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was employed to identify and select relevant studies. Seven electronic databases were thoroughly searched for eligible studies from June 1st to 30th, 2023. Methodological quality was assessed using RoB 2.0 or RoBANS 2. Results: Thirteen studies (five randomized controlled trials and eight quasi-experimental studies) were selected in the systematic review. Among the selected studies, eight provided AI robot interventions individually, whereas five used a group format, primarily addressing older adults with cognitive impairment or dementia. Depression was the most frequently addressed psychological outcome, with six of ten studies reporting significant effects. Additionally, five studies each highlighted significant effects on emotions, such as positive expressiveness and enjoyment. However, quality of life, anxiety, and loneliness revealed divergent results. Conclusion: AI robots show potential in alleviating psychological challenges for older adults. However, due to the scarcity of high-quality studies, the review recommends conducting more randomized controlled trials with rigorous designs. This review is expected to provide valuable insights for planning and executing AI robot interventions to improve psychological outcomes for community-dwelling older adults in future research.

Background: With a rapid decrease in tuberculosis (TB) incidence, the significance of latent tuberculosis infection (LTBI) has been underscored in South Korea. Although South Korea does not have a high proportion of immigrants compared to other countries, there is a growing argument that it should actively embrace immigrants as a solution to address issues of low birth rates and population aging. This study aimed to assess TB incidence among immigrants who participated a pilot LTBI screening program in South Korea. Methods: Records of immigrants participated in a pilot LTBI screening program in South Korea between 2018 and 2019 were linked with Korean National TB Surveillance System to determine TB development. Participants underwent interferon-gamma release assay (IGRA) and chest X-rays. Standardized incidence ratios (SIRs) stratified by age, country of origin’s TB burden was calculated with a reference group of general South Korean population. Results: Of a total of 9,517 participants, 14 TB cases were identified. Participants with positive IGRA results who did not initiate LTBI treatment showed TB incidence of 312.5 per 100,000 person-years, whereas those with negative results showed TB incidence of 34.4 per 100,000 person-years, resulting in an incidence rate ratio of 9.08 (95% confidence interval [CI], 2.50–32.99). SIR of TB among total participants including those with negative IGRA results was 2.60 (95% CI, 1.54–4.38; P < 0.001), whereas SIR among those with positive IGRA results was 5.86 (95% CI, 3.15–10.89; P < 0.001). In the calculation of SIR among participants with positive IGRA results, those aged under 35 from high TB-burden countries or intermediate TBburden countries showed a high SIR (18.08; 95% CI, 2.55–128.37; P = 0.004), and 11.30 (95% CI, 2.82–45.16; P < 0.001), respectively). Contrary to previous reports that suggest the majority of elderly population with a positive IGRA result were due to remote infection and had a lower TB risk compared to younger ages, SIR among those aged 65 or over from intermediate TB-burden countries was 6.15 (95% CI, 0.87–43.69; P = 0.069), which was comparable to that in younger participants aged between 35 and 49 (SIR, 4.87; 95% CI, 1.22–19.49; P = 0.025) or those aged between 50 and 64 (SIR, 4.62; 95% CI, 1.73–12.31; P = 0.002). Conclusion Young immigrants with positive IGRA results from countries with high or intermediate TB burden showed a relatively high TB risk compared to a general South Korea population. In addition, unexpected high TB risk was observed among elderly immigrants with positive IGRA results. In establishing future policies for LTBI in immigrants in South Korea, screenings should primarily focus on younger age group (who aged under 35).Additionally, further research is needed on the high TB risk observed in elderly immigrants.

Herpes simplex encephalitis is known to cause intracranial hypertension and cerebral edema. When cerebral edema occurs, venous sinuses are compressed, resulting in congestion and thrombosis. An arteriovenous fistula may form as a result, particularly in conjunction with superior sagittal sinus thrombosis. In this report, the authors describe a patient with protein S and C deficiency who developed venous sinus thrombosis and dural arteriovenous fistula after experiencing herpes simplex encephalitis.

Hidradenitis suppurativa (HS) is a chronic inflammatory condition that is difficult to diagnose, with a period of 10.0± 9.6 years from symptom onset to diagnosis. A 32-year-old Asian man presented with bilateral postauricular abscesses that first appeared 5 years previously. Despite several incisions and drainage, the symptoms only temporarily improved and continued to recur. On physical examination, chronic scars and sinus tracts were observed around the lesion. Postauricular HS was diagnosed, and surgical treatment was performed. We performed a wide excision and reconstructed the defect using a posterior auricular artery perforator-based keystone flap. Histological examination confirmed the diagnosis of HS. The reconstruction was successful, and there was no recurrence for 2 years after surgery. HS is difficult to diagnose without specific attention. Although the postauricular region is not a typical site of HS, it can occur in this area. Therefore, if a patient presents with recurrent abscesses in the postauricular region, HS should be considered. Additionally, if HS is diagnosed in the postauricular region, wide excision with reconstruction using a posterior auricular artery perforator-based keystone flap can lead to a favorable outcome.
