Association between history of hookah use and symptoms of postpartum depression: A population-based study.

OBJECTIVE: Although several biologic, psychosocial, and behavioral factors have been linked to postpartum depressive symptoms, studies examining the association between non-cigarette tobacco products and symptoms of postpartum depression are currently lacking. This study examined the association between hookah use and postpartum depressive symptoms. METHODS: A cross-sectional study was conducted using data from the US Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System 2016-2020. Self-reported data on hookah use in the last 2 years and maternal mental health were captured using a structured questionnaire. Descriptive and inferential statistics were performed. RESULTS: The final study sample consisted of 106 894 participants. Approximately 8.2% of the participants reported postpartum depressive symptoms and 4.1% reported hookah use in the past 2 years. Compared with those without postpartum depressive symptoms, participants with postpartum depressive symptoms were more likely to be hookah users (5.5% vs 4.0%, P < 0.001). After adjustment for confounders, the odds of having postpartum depressive symptoms were significantly higher among participants who used a hookah in the past 2 years compared with non-users; adjusted odds ratio (95% confidence interval) 1.20 (1.03-1.40); P = 0.022. CONCLUSION: In a large, population-based sample of US women, hookah use in the past 2 years significantly increased the odds of having postpartum depressive symptoms, independent of potential confounders. This finding underscores the need for healthcare providers to communicate effectively about the health risks of hookah use.

Homalomena pineodora essential oil nanoparticle inhibits diabetic wound pathogens.

Essential oil of Homalomena pineodora inhibits diabetic pathogens; however, the activity was not sustainable when applied as wound dressing. This study aims to synthesise the essential oil nanoparticle using chitosan. The nanoparticles were synthesised with ion gelation method, confirmed by spectroscopic analysis. The spherical nanoparticles display a size of 70 nm, with strong surface charge of +24.10 mV. The nanoparticles showed an initial burst release followed by a slow release pattern for 72 h, following the first order of kinetic. The release behaviour was ideal for wound dressing. The antimicrobial activity was broad spectrum. The formation of nanoparticle enhanced the antimicrobial efficacy of the essential oil. The nanoparticle also showed a concentration-dependent killing behaviour on time-kill assay. In the 3D collagen wound models, the nanoparticles reduced the microbial growth by 60-80%. In conclusion, H. pineodora nanoparticles showed pharmaceutical potential in inhibiting microbial growth on diabetic ulcers.

Timeliness of Treatment Initiation in Newly Diagnosed Patients With Breast Cancer.

BACKGROUND: Evidence-based timeliness benchmarks have been established to assess quality of breast cancer care, as delays in treatment are associated with poor clinical outcomes. However, few studies have evaluated how current breast cancer care meets these benchmarks and what factors may delay the timely initiation of treatment. PATIENTS AND METHODS: Demographic and disease characteristics of 377 newly diagnosed patients with breast cancer who initiated treatment at Tufts Medical Center (2009-2015) were extracted from electronic medical records. Time from diagnosis to initial surgery and time from diagnosis to initiation of hormone therapy were estimated with Kaplan-Meier curves. Multivariable regression analysis was used to identify factors associated with treatment delays. Thematic analysis was performed to categorize reasons for delay. RESULTS: Of 319 patients who had surgery recommended as the first treatment, 248 (78%) met the 45-day benchmark (median, 28 days; 25th-75th %, 19-43). After adjusting for potential confounders, multivariable regression analysis revealed that negative hormone receptor status (odds ratio, 3.48; 95% confidence interval, 1.44-8.43) and mastectomy (odds ratio, 4.07; 95% confidence interval, 2.10-8.06) were significantly associated with delays in surgery. Delays were mostly owing to clinical complexity or logistical/financial reasons. Of 241 patients eligible for hormone therapy initiation, 232 (96%) met the 1-year benchmark (median, 147 days; 25th-75th %, 79-217). CONCLUSION: Most patients met timeliness guidelines for surgery and initiation of hormone therapy, although risk factors for delay were identified. Knowledge of reasons for breast cancer treatment delay, including clinical complexity and logistical/financial issues, may allow targeting interventions for patients at greatest risk of care delays.

Degradation of 17α-ethinylestradiol by nano zero valent iron under different pH and dissolved oxygen levels.

The catalytic properties of nanoparticles (e.g., nano zero valent iron, nZVI) have been used to effectively treat a wide range of environmental contaminants. Emerging contaminants such as endocrine disrupting chemicals (EDCs) are susceptible to degradation by nanoparticles. Despite extensive investigations, questions remain on the transformation mechanism on the nZVI surface under different environmental conditions (redox and pH). Furthermore, in terms of the large-scale requirement for nanomaterials in field applications, the effect of polymer-stabilization used by commercial vendors on the above processes is unclear. To address these factors, we investigated the degradation of a model EDC, the steroidal estrogen 17α-ethinylestradiol (EE2), by commercially sourced nZVI at pH 3, 5 and 7 under different oxygen conditions. Following the use of radical scavengers, an assessment of the EE2 transformation products shows that under nitrogen purging direct reduction of EE2 by nZVI occurred at all pHs. The radicals transforming EE2 in the absence of purging and upon air purging were similar for a given pH, but the dominant radical varied with pH. Upon air purging, EE2 was transformed by the same radical species as the non-purged system at the same respective pH, but the degradation rate was lower with more oxygen - most likely due to faster nZVI oxidation upon aeration, coupled with radical scavenging. The dominant radicals were OH at pH 3 and O2- at pH 5, and while neither radical was involved at pH 7, no conclusive inferences could be made on the actual radical involved at pH 7. Similar transformation products were observed without purging and upon air purging.
