We compared two groups, each receiving either 24 h (Group I) or 18 h (Group II) of continuous phototherapy in terms of demographic characteristics and efficacy (rate of decrease in TSB levels with phototherapy). No control TSB measurements were performed in the study groups until the end of phototherapy for the predetermined durations. Declines in TSB after phototherapy were significantly greater in Group I than in Group II, both in terms of mg/dl (11.81 ± 2.93 mg/dl vs. 10.75 ± 2.48 mg/dl, P = .0008) and percentage (56.71 ± 9.06% vs. 52.86 ± 8.37%, P = .0002). However, the rate of TSB reduction after phototherapy in mg/dl/h (0.59 ± 0.13 mg/dl/h vs. 0.49 ± 0.12 mg/dl/h, P = <.0001) and percentage per hour (2.93 ± 0.37% vs. 2.36 ± 0.46%, P = <.0001) were significantly higher in Group II than in Group I. This indicates an inverse time-response relationship between the duration of phototherapy and the response rate in the study groups. Although the 24-h phototherapy course showed greater efficacy concerning the primary bilirubin outcome measures (decline in TSB in mg/dl and %), the 18-h course of phototherapy treatment provided better hourly outcomes and reached its saturation point around the 18th hour. Therefore, an 18-h phototherapy without TSB monitoring until the end of the phototherapy should be considered for jaundiced newborns lacking neurotoxicity risk factors.</p>","PeriodicalId":17521,"journal":{"name":"Journal of Tropical Pediatrics","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142400633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interpretation of epidemiological data on candidemias and their antifungal resistance plays a vital role in aiding diagnosis and guiding clinicians in treatment decisions. From 2014 to 2021, a retrospective analysis was conducted in İstanbul, Turkey; comparing Candida albicans and non-albicans (NAC) spp in both surviving and deceased groups. Furthermore, an examination of Candida parapsilosis and other species was performed, assessing various clinical and laboratory parameters. Among 93 patients, with a median age of 17 months, C. parapsilosis emerged as the predominant isolated species (44%), followed by C. albicans (34.4%). Resistance to fluconazole, voricanozole, and echinocandins, along with a history of broad-spectrum antibiotic use were found to be significantly higher in the non-albicans Candida group compared to C. albicans group. In the C. parapsilosis group, statistically lower age was identified in comparison to the other groups (P = .018). In addition, high fluconazole and voriconazole resistance was detected in Candida parapsilosis spp. Our study highlights a notable prevalence of C. parapsilosis, particularly in younger children, which is different from similar studies in childhood. This trend may be attributed to the common use of total parenteral nutrition and central venous catheter in gastrointestinal disorders and metabolic diseases. Furthermore, as anticipated, high azole resistance is noted in C. parapsilosis and other non-albicans Candida species. Interestingly, resistance to both amphotericin B and echinocandins within this group has been notably high.

The secondary aim was to compare the strategies adopted by these hospitals to control the detrimental effects of noise on newborns. A detailed noise survey was conducted in the NICUs of two private and two government hospitals in the Jodhpur district, India. The noise survey was performed for a duration of 48 h using \"Sound Ear 3-300\" noise meters. The analyses were measured in Leq (equivalent continuous sound level) A-weighted decibels (dBA). The extracted data analysis revealed that the noise measured was in the range of 61.62-82.32 dBA in four NICUs of the district. The results also revealed a statistically significant difference between the NICU noise of private and government hospitals. The levels of alarming sounds differed between the hospitals with a general trend of lesser alarming sounds in private hospitals. The major differences in strategies adopted were that both private hospitals had a protocol to purposely reduce levels of alarming sounds when heard, and purposely limited the number of staff present in certain areas of the NICU, which were correlated with reduced sound compared to the government hospitals.
