ABSTRACT

OBJECTIVE: To observe the clinical efficacy of different treatment frequency of auricular bloodletting combined with auricular point sticking for acne vulgaris.

METHODS: A total of 90 patients with acne vulgaris were randomized into a treatment group 1 (30 cases, 2 cases dropped off), a treatment group 2 (30 cases, 4 cases dropped off) and a treatment group 3 (30 cases, 5 cases dropped off). Combination therapy of auricular bloodletting and auricular point sticking at Fei (CO₁₄), Shenmen (TF₄), Neifenmi (CO₁₈) and Shenshangxian (TG₂p) were given once a week, twice a week and 3 times a week in the treatment group 1, the treatment group 2 and the treatment group 3 respectively, 4 weeks were as one course and totally 3 courses were required in the 3 groups. Before treatment and after 1, 2, 3 courses of treatment, the scores of global acne grading system (GAGS), skin lesion and quality of life-acne (QoL-Acne) were observed, the clinical efficacy was evaluated after 3 courses of treatment and the recurrence rate was evaluated in follow-up of 1 month after treatment in the 3 groups.

RESULTS: Compared before treatment, the scores of GAGS and skin lesion were decreased at each time point in the 3 groups (P<0.05), the QoL-Acne scores were increased after 1 course of treatment in the treatment group 3 and after 2, 3 courses of treatment in the 3 groups (P<0.05). There were no statistical differences in scores of GAGS, skin lesion and QoL-Acne among the 3 groups (P>0.05). There were no statistical differences in effective rate and recurrence rate among the 3 groups (P>0.05).

CONCLUSION: Different frequency of auricular bloodletting combined with auricular point sticking have similar efficacy in treating acne vulgaris, all can improve the skin lesion and quality of life in patients with acne vulgaris, and have a cumulative effect and good long-term curative effect.

ABSTRACT

Agricultural soils are leading sources of reactive nitrogen (Nr) species including nitrogen oxides (NO_x), ammonia (NH₃), and nitrous oxide (N₂O). The propensity of NO_x and NH₃ to generate ozone and fine particulate matter and associated impacts on health are highly variable, whereas the climate impacts of long-lived N₂O are independent of emission timing and location. However, these impacts have rarely been compared on a spatially resolved monetized basis. In this study, we update the nitrogen scheme in an agroecosystem model to simulate the Nr emissions from fertilized soils across the contiguous United States. We then apply a reduced-form air pollution health effect model to assess air quality impacts from NO_x and NH₃ and a social cost of N₂O to assess the climate impacts. Assuming an $8.2 million value of a statistical life and a $13,100/ton social cost of N₂O, the air quality impacts are a factor of ∼7 to 15 times as large as the climate impacts in heavily populated coastal regions, whereas the ratios are closer to 2.5 in sparsely populated regions. Our results show that air pollution, health, and climate should be considered jointly in future assessments of how farming practices affect Nr emissions.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate oral bacteria- and interleukin (IL)-1β-induced protein and mRNA expression profiles of monocyte chemoattractant protein-1-induced protein (MCPIP)-1 and mucosa-associated lymphoid tissue lymphoma translocation protein (MALT)-1 in human gingival keratinocyte monolayers and organotypic oral mucosal models.

METHODS: Human gingival keratinocyte (HMK) monolayers were incubated with Porphyromonas gingivalis, Fusobacterium nucleatum, P. gingivalis LPS and IL-1β. The protein levels of MCPIP-1 and MALT-1 were examined by immunoblots and mRNA levels by qPCR. MCPIP-1 and MALT-1 protein expression levels were also analyzed immunohistochemically using an organotypic oral mucosal model. One-way analysis of variance (ANOVA) followed by Tukey’s correction was used in statistical analyses.

RESULTS: In keratinocyte monolayers, MCPIP-1 protein expression was suppressed by F. nucleatum and MALT-1 protein expression was suppressed by F. nucleatum, P. gingivalis LPS and IL-1β. P. gingivalis seemed to degrade MCPIP-1 and MALT-1 at all tested time points and degradation was inhibited when P. gingivalis was heat-killed. MCPIP-1 mRNA levels were increased by P. gingivalis, F. nucleatum, and IL-1β, however no changes were observed in MALT-1 mRNA levels.

CONCLUSION: Gingival keratinocyte MCPIP-1 and MALT-1 mRNA and protein expression responses are regulated by infection and inflammatory mediators. These findings suggest that periodontitis-associated bacteria-induced modifications in MCPIP-1 and MALT-1 responses can be a part of periodontal disease pathogenesis.

ABSTRACT

Aim: To evaluate the association between pretreatment diffusion-weighted MRI (DW-MRI) and 12-month radiological response in locally recurrent rectal cancer treated with carbon ion radiotherapy. Methods: Histogram analysis was performed on pretreatment DW-MRI for patients re-irradiated with carbon ion radiotherapy for local recurrence of rectal cancer. Results: A total of 17 patients were enrolled in the study. Pretreatment DW-MRI b-value of 1000 s/mm² (b1000) and apparent diffusion coefficient (ADC) lesion median values for 1-year nonresponders (six patients) and responders (11 patients) demonstrated a median (interquartile of median values) of 62.5 (23.9) and 34.0 (13.0) and 953.0 (277.0) and 942.5 (339.0) μm²/s, respectively. All b1000 histogram features (h-features) and ADC h-kurtosis showed statistically significant differences, whereas only b1000 h-median, b1000 h-interquartile range and ADC h-kurtosis demonstrated remarkable diagnostic accuracy. Conclusion: DW-MRI showed promising results in predicting carbon ion radiotherapy outcome in local recurrence of rectal cancer, particularly with regard to b1000 h-median, b1000 h-interquartile range and ADC h-kurtosis.

ABSTRACT

BACKGROUND: General practitioners (GPs) play an essential role in the sustainable management of attention-deficit/hyperactivity disorder (ADHD). To our knowledge, the healthcare programme described here is the first integrated care programme for paediatric ambulatory care embedded in GP-centred-healthcare in Germany.

OBJECTIVES: To compare the health-service-utilisation of patients with ADHD enrolled in a GP-centred-paediatric-primary-care-programme with usual care in terms of disease-related hospitalisation, pharmacotherapy and psychotherapy.

METHODS: In 2018, we conducted a retrospective cohort study of 3- to 18-year-old patients with ADHD in Baden-Wuerttemberg, southern Germany. The intervention group (IG) comprised patients enrolled in a GP-centred-paediatric-primary-healthcare-programme and consulted a participating GP for ADHD at least once. GP-centred-paediatric-primary-care provides high continuity of care, facilitated access to specialist care, extended routine examinations and enhanced transition to adult healthcare. Patients in the control group (CG) received usual care, meaning they consulted a non-participating GP for ADHD at least once. Main outcomes were disease-related hospitalisation, pharmacotherapy and psychotherapy. Multivariable logistic regression was performed to compare groups.

RESULTS: A total of 2317 patients were included in IG and 4177 patients in CG. Mean age was 8.9 ± 4.4. The risk of mental-disorder-related hospitalisations was lower in IG than CG (odds ratio (OR): 0.666, 95% confidence interval (CI): 0.509-0.871). The prescription rate for stimulants was lower in IG (OR: 0.817; 95% CI: 0.732-0.912). There was no statistically significant difference in the participation rate of patients in cognitive behavioural therapy between groups (OR: 0.752; 95% CI: 0.523-1.080).

CONCLUSION: Children and adolescents with ADHD enrolled in GP-centred-paediatric-primary-care are at lower risk of mental-disorder-related hospitalisation and less likely to receive stimulants.

ABSTRACT

Iron is essential for many biological processes, but iron levels must be tightly regulated to avoid harmful effects of both iron deficiency and overload. Here, we perform genome-wide association studies on four iron-related biomarkers (serum iron, serum ferritin, transferrin saturation, total iron-binding capacity) in the Trøndelag Health Study (HUNT), the Michigan Genomics Initiative (MGI), and the SardiNIA study, followed by their meta-analysis with publicly available summary statistics, analyzing up to 257,953 individuals. We identify 123 genetic loci associated with iron traits. Among 19 novel protein-altering variants, we observe a rare missense variant (rs367731784) in HUNT, which suggests a role for DNAJC13 in transferrin recycling. We further validate recently published results using genetic risk scores for each biomarker in HUNT (6% variance in serum iron explained) and present linear and non-linear Mendelian randomization analyses of the traits on all-cause mortality. We find evidence of a harmful effect of increased serum iron and transferrin saturation in linear analyses that estimate population-averaged effects. However, there was weak evidence of a protective effect of increasing serum iron at the very low end of its distribution. Our findings contribute to our understanding of the genes affecting iron status and its consequences on human health.

ABSTRACT

OBJECTIVE: To estimate the changes in infertility from 1995-2019 and determine the association of individual-level characteristics with fertility in the United States.

DESIGN: Cross-sectional study.

SETTING: Periodic data from 1995, 2002, 2006-2010, 2011-2013, 2013-2015, 2015-2017, and 2017-2019 cycles of the National Survey for Family Growth were used for this analysis. The National Survey for Family Growth comprises samples of the household-level population of women aged 15-44 years in the United States.

PATIENT(S): Surveyed married and cohabiting women aged 15-44 years.

INTERVENTION(S): None.

MAIN OUTCOME MEASURE(S): The primary outcomes were the rates of infertility across subgroups of married or cohabiting women. For secondary outcomes, we performed bivariable and multivariable logistic regression models using the pooled sample (N = 53,764) to determine the association of individual-level characteristics, including age, parity, pelvic inflammatory disease treatment, education, income, race or ethnicity, and receipt of sexual and reproductive health services, with the odds of 12-month infertility among married or cohabiting women.

RESULT(S): The fluctuations in infertility over this period, with a low of 5.8% in 2006-2010 and a high of 8.1% in 2017-2019, were not found to be statistically significant. This trend was present across nearly all subgroups. The multivariable model showed that women who were older and nulliparous, had fewer years of education, had lower income, were non-Hispanic black, or were not receiving sexual and reproductive health services were more likely to be infertile.

CONCLUSION(S): This study confirms that parity, age, race, and education level continue to have an association with infertility. Further, the results demonstrate that access to sexual and reproductive health services plays an important role in infertility. In contrast to previous studies, infertility in the United States is no longer on the decline, and Hispanic ethnicity did not have a significant relationship with infertility. Given the rise of sexually transmitted infections and the persistent lack of access to sexual and reproductive health services, particularly among already vulnerable groups, the connection between access to care and infertility is ripe for further investigation.

ABSTRACT

OBJECTIVE: To determine whether endometrial receptivity analysis (ERA) improves live births in patients with and without a history of unsuccessful frozen embryo transfers (FETs).

DESIGN: Retrospective cohort study.

SETTING: Large reproductive center.

PATIENT(S): Patients with and without ERA before euploid single FET were included in the analysis.

INTERVENTION(S): Subjects in the exposed group underwent ERA and ERA-timed FETs. Subjects in the unexposed group followed a standard protocol FET without ERA. Outcomes were compared between nonreceptive and receptive subjects undergoing an ERA-timed FET and between ERA-timed vs. standard protocol FETs.

MAIN OUTCOME MEASURE(S): The primary outcome was a live birth; secondary outcomes were biochemical and clinical pregnancy rates.

RESULT(S): A total of 307 ERA-timed FETs and 2,284 standard protocol FETs were analyzed. One hundred twenty-five patients (40.7%) were ERA receptive, and 182 (59.3%) were ERA nonreceptive. After adjusting for the number of the previously failed FETs, there was no difference in the proportion of receptive and nonreceptive ERA results. There were no statistically significant differences in live births in patients with ERA-receptive vs. ERA-nonreceptive results (48.8% and 41.7%, respectively; adjusted odds ratio 1.17; 95% CI, 0.97-1.40). There were no statistically significant differences in live births in patients with or without ERA testing results before FET (44.6% and 51.3%, respectively; adjusted odds ratio 0.87; 95% CI, 0.73-1.04).

CONCLUSION(S): Patients with an increasing number of previous failed euploid FET cycles are not at an increased risk of a displaced window of implantation. Patients categorized as receptive vs. nonreceptive and those without ERA testing results have comparable FET success rates.

ABSTRACT

INTRODUCTION: Simulation-based education is frequently used in transition programs for new graduate nurses. Simulation-based education is implemented as a measure to practice nursing skills, gain experience, and prepare nurses for caring in challenging situations, such as acute situations. However, concerns about the data supporting the use of simulation are obtained from small studies that do not use validated measurement scales.

OBJECTIVE: This study aimed to explore the influence of simulation-based education on new graduate nurses’ perceived ability to provide care in acute situations.

METHODS: A total of 102 new graduate nurses participated in simulation-based education as a mandatory part of an introductory program. They completed a premeasurement and a postmeasurement using the Perception to Care in Acute Situations scale. The Wilcoxon signed-rank test and the paired samples t test were used to test the statistical significance of outcomes for the simulation-based education, with the alpha set at 0.05. Cohen’s d formula was used to calculate the effect size.

RESULTS: The Wilcoxon signed-rank test on the total scale score showed that simulation-based education resulted in a statistically significant change in the nurses’ perceptions of their ability to care in acute situations (N = 99; Z = 7877; P < .001). The paired samples t test showed that the mean posteducation score was significantly higher (P < .001) in the total score. Cohen’s d formula (-1.24) indicated a large effect size on the total score.

CONCLUSION: Simulation-based education can provide an effective means of improving new graduate nurses’ perceived ability to provide care in acute situations.

ABSTRACT

BACKGROUND: Cystinosis is a rare autosomal recessive lysosomal storage disease, associated with high morbidity and mortality. Mutations in the CTNS gene disable a membrane protein responsible for the transport of cystine out of the lysosome. Loss of transporter function leads to intralysosomal cystine accumulation and long-term damage to various tissues and organs, including the kidneys, eyes, liver, muscles, pancreas, and brain. The only cystine-depletion therapy for treatment of cystinosis is cysteamine which requires frequent administration of high doses and often causes gastrointestinal pain as well as pungent sulfurous odor in patients. The current in vitro study evaluated antioxidants, N-acetylcysteine amide (NACA; NPI-001) and (2R,2R’)-3,3′-disulfanediyl bis(2-acetamidopropanamide) (diNACA; NPI-002), as potential treatments for cystinosis.

METHODS: Cytotoxicity of cysteamine, NACA and diNACA was evaluated in cultured human cystinotic fibroblasts (HCFs). HCFs were cultured in 96 well plates incubated for 0-72 h in the presence of 25, 50 or 75 μM each of either cysteamine, NACA or diNACA along with an untreated control. Media was removed and cell viability assessed. Next, cystine-depleting activities of cysteamine, NACA and diNACA were screened in HCFs cell culture utilizing an inexpensive, proven colorimetric assay. HCFs were seeded and allowed to reach approximately 80% confluence before the addition of the test articles: 50 μM of either cysteamine, NACA or diNACA in media along with an untreated control. HCFs were incubated, harvested, and cystine was reduced to cysteine, the concentration of which was then determined per quantity of protein compared to a cysteine standard. Statistically significant cystine depletion was determined by paired t-test versus untreated control (p < 0.05).

RESULTS: Neither cysteamine, NACA nor diNACA at 25, 50 or 75 μM caused cytotoxicity in HCFs. Treatment with all tested concentrations (25, 50 or 75 µM) of either NACA or diNACA at 48 or 72 h resulted in statistically significant increases in cell viability, relative to untreated control, whereas the higher concentrations (50 or 75 µM) of cysteamine achieved statistical significance at both timepoints but not the lowest concentration (25 µM). All test articles depleted cystine from HCFs compared to control. NACA depletion of cystine was statistically superior to cysteamine at 6, 24 and 48 h and numerically greater at 72 h. DiNACA depletion of cystine was statistically superior to cysteamine at 6 and 48 h, slightly numerically greater at 24 h and slightly less at 72 h.

CONCLUSIONS: NACA and diNACA were non cytotoxic to HCFs and significantly increased cell viability. Cystine reduction was determined as percent of control after incubation with 50 µM of NACA, diNACA or cysteamine in HCFs cell culture for 6, 24, 48 and 72 h. Of the three test articles, NACA exhibited most rapid and greatest potency in cystine reduction. Rank order potency for cystine reduction over time was observed, NACA > diNACA ≥ cysteamine. Therefore, further study of NACA and diNACA as potential treatments for cystinosis is warranted.
