RESUMEN
A 44-year-old male presented with a 2-month history of erythematous ulcerative papules and plaques on the scalp, face, and bilateral lower legs. He had a 5-year history of well-controlled HIV on antiretroviral therapy and recurrent syphilis infections. His face had violaceous plaques, while bilateral ankles and calves had ulcerative lesions with necrotic centers and purple borders. The morphologies clinically mimicked pyoderma gangrenosum on the lower extremities and cutaneous lymphoma on the face. Biopsy and reactive rapid plasma reagin confirmed a diagnosis of lues maligna, and the patient was successfully treated with penicillin G benzathine.
RESUMEN
BACKGROUND: Patch testing for multiple cross-reactive allergens for allergic contact dermatitis (ACD) may not be necessary because of copositivity. OBJECTIVES: We evaluated the formaldehyde group allergens to determine the optimal, most cost-effective allergens to test. METHODS: A retrospective analysis of Mayo Clinic (1997-2022) examined the well-established copositive formaldehyde group: formaldehyde, quaternium 15, hexahydro-1,3,5-tris(2-hydroxyethyl)triazine, diazolidinyl urea, imidazolidinyl urea, toluenesulphonamide formaldehyde resin, DMDM hydantoin, and ethyleneurea melamine formaldehyde mix. Patch Optimization Platform identified which single formaldehyde-related allergen optimally captures patients with clinically relevant ACD. Next, Patch Optimization Platform determined the optimal additional 1, 2, 3, etc. allergens. Cost per patch test was $5.19 (Medicare 2022). RESULTS: A total of 9832 patients were tested for all listed allergens, with 830 having positive patch test results. Patch Optimization Platform determined that quaternium 15 alone captures 53% of patients with ACD to the formaldehyde group; adding the optimal second allergen (formaldehyde 1%) captures 78%; the optimal 5 top allergens capture >94% of patients. The incremental cost per additional diagnosis increased up to 44-fold as the number of allergens tested increased. LIMITATIONS: Data are from a single institution, and the cost per test was fixed according to Medicare Part B in 2022. CONCLUSIONS: For diagnosing ACD, we recommend considering an optimized allergen selection algorithm.
RESUMEN
The isotope shifts in electron affinities of Pb were measured by Walter et al. [Phys. Rev. A 106, L010801 (2022)] to be -0.002(4) meV for 207-208Pb and -0.003(4) meV for 206-208Pb by scanning the threshold of the photodetachment channel Pb-(S3/2â¦4) - Pb (3P0), while Chen and Ning reported 0.015(25) and -0.050(22) meV for the isotope shifts on the binding energies measured relative to 3P2 using the SEVI method [J. Chem. Phys. 145, 084303 (2016)]. Here we revisited these isotope shifts by using our second-generation SEVI spectrometer and obtained -0.001(15) meV for 207-208Pb and -0.001(14) meV for 206-208Pb, respectively. In order to aid the experiment by theory, we performed the first ab initio theoretical calculations of isotope shifts in electron affinities and binding energies of Pb, as well as the hyperfine structure of 207Pb-, by using the MCDHF and RCI methods. The isotope shifts in electron affinities of 207-208Pb and 206-208Pb are -0.0023(8) and -0.0037(13) meV for the 3P0 channel, respectively, in good agreement with Walter et al.'s measurements. The isotope shifts in binding energies relative to 3P1,2, -0.0015(8) and -0.0026(13) meV for 207-208Pb and 206-208Pb, respectively, are compatible with the present measurements. The hyperfine constant for the ground state of 207Pb- obtained by the present calculations, A(S3/2â¦4)=-1118 MHz, differs by a factor of 3 from the previous estimation by Bresteau et al. [J. Phys. B: At., Mol. Opt. Phys. 52, 065001 (2019)]. The reliability is supported by the good agreement between the theoretical and experimental hyperfine parameters of 209Bi.
RESUMEN
Objective: To explore the association between hair trace element and all-cause death in the elderly in Hainan Province. Methods: The subjects of the study were elderly people from China Hainan Centenarian Cohort Study, a total of 163 elderly were included. The association between hair trace element level and all-cause death was analyzed by using Cox proportional risk regression model. Results: After fully adjusting the covariates, the multiple Cox proportional hazards regression analyses showed that selenium (Se), manganese (Mn), strontium (Sr) concentrations in hair were significantly associated with all-cause mortality, the hazard ratio (HR) were 0.72 (95%CI: 0.54-0.98, P=0.035), 1.50 (95%CI: 1.07-2.11, P=0.020) and 0.54 (95%CI: 0.37-0.79, P=0.001), respectively. Subgroup and cross analysis showed that hair copper (Cu) were significant association with death in the people with anemia, the HR were 1.81 (95%CI: 1.13-2.88, P=0.013). And, hair Mn interacted with anemia, the HR was 0.46 (95%CI: 0.22-0.94, P=0.033). Conclusions: Se, Mn and Sr concentrations in hair were associated with the elevated risk for all-cause death in the elderly in Hainan. Se, Mn and Sr concentrations in hair can be used as a reference index for the prediction of the death risk of long-lived elderly in community, suggesting that the daily diet of elderly people are rich and diverse, in order to maintain normal and balanced trace element content in the body.

Objective: To investigate the distribution characteristics of sex hormones and their relationship with all-cause mortality in Hainan female centenarians. Methods: All the subjects were from China Hainan Centenarian Cohort Study. A total of 717 female centenarians were included in the final analysis. Kaplan-Meier method was used to draw the survival curve, and Cox proportional hazard regression was used to analyze the relationship between sex hormones and survival time. Results: The M(Q1, Q3) of estradiol and progesterone among female centenarians was 32.60 (18.40, 58.70) pmol/L and 0.62 (0.32, 1.01) nmol/L. The estradiol (pmol/L) and progesterone (nmol/L) in the survival and death groups were 26.65 vs.37.80, 0.54 vs.0.69, respectively, with statistical differences (P<0.05). Cox multivariate analysis showed that estradiol and progesterone were significantly associated with death (P<0.05), the hazard ratio (HR) of estradiol Q4 was 1.58 (95%CI: 1.17-2.15), and the HR of progesterone Q3 was 1.53 (95%CI: 1.10-2.12), HR for Q4 was 1.63 (95%CI: 1.15-2.32). Subgroup and cross-analysis showed that estradiol was statistically significant with hypertension, diabetes, and low high-density lipoprotein cholesterol (P<0.05), and progesterone interacted with diabetes (P=0.016), while testosterone interacted with low high-density lipoprotein cholesterol (P=0.034). Conclusion: It is suggested that the estrogen levels of female centenarians in Hainan were associated with a higher mortality risk and an increased risk of cardiovascular metabolic disease (such as diabetes, hypertension, and abnormal lipid metabolism).

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase â ¢ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ2=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

1. Melatonin is an indole hormone that, among its myriad biological functions, regulates circadian and seasonal rhythms in animals. The ASMT gene plays an essential role in melatonin synthesis. However, in chickens, little is known about the regulatory elements governing its transcription.2. The following study identified the transcription start site of the chicken ASMT gene by 5'-RACE. Then, the proximal minimal promoter was identified using a series of 5' truncations of the ASMT promoter (e.g. -3502/+17, -2698/+17, -2003/+17, -1378/+17, and -254/+17). Site-directed mutagenesis, overexpression, and electrophoretic mobility shift assay (EMSA) were applied to show that the transcription factor Oct-1 binds to the promoter region of ASMT.3. The translation start site was located 19 bp upstream from the translational start site. The luciferase reporter assay confirmed that the core promoter of chicken ASMT gene was in the -254/+17 region. Using site-directed mutagenesis, overexpression, and EMSA, Oct-1 bound the promoter of ASMT.4. Overall, Oct1 plays an important role in the transcriptional regulation of chicken ASMT gene.

Objective: To explore the relationship between nutritional status and depression of centenarians in Hainan Province. Methods: A total of 1 002 elderly people in Hainan Province who were 100 years of age or older on June 1, 2014 were included in the study. The basic condition questionnaire, Mini Nutritional Assessment Short-Form (MNA-SF), Instrumental Activities of Daily Living-Lawton scale (Lawton-IADL) and Geriatric Depression Scale (GDS-15) were used to collect the subjects' demographic characteristics, disease history, nutritional status, functional status of daily activities, and depression, respectively. The restricted cubic spline fitting logistic regression model was used to analyze the relationship between the scores of MNA-SF and depression. The multivariable logistic regression model was used to analyze the relationship between nutritional status and depression in the total population and different subgroups of daily activity function. Results: The M (Q1, Q3) of subjects' age was 102 (101, 104) years old, among which 82.0% (822) were women. The prevalence of malnutrition, impaired daily activities, and depression was 20.8% (208 cases), 64.7% (648 cases) and 28.5%(286 cases), respectively. Restricted cubic spline fitting logistic regression model showed a linear association between the scores of the MNA-SF and depression (P=0.251). The higher the MNA-SF score was, the lower the risk of depression was in centenarians. Multivariable logistic regression model analysis showed that after adjusting for sex, education level, diabetes, hypertension, coronary heart disease, visual function, hearing function, and functional status of daily activities, malnutrition was positively associated with the development of depression in the total population and the subgroup with impaired daily activities [OR (95%CI) was 1.50 (1.07-2.11) and 1.56 (1.09-2.24), respectively], but not in the subgroup with good daily activities [OR (95%CI): 0.77 (0.21-2.80)]. Conclusion: Malnutrition is positively associated with depression, especially in the centenarians with impaired daily activities.

Objective: To analyze the genotype characteristics of children with monogenic nephrolithiasis. Methods: The clinical data and genetic test results of 56 children with monogenic nephrolithiasis diagnosed and treated in Beijing Friendship Hospital, Capital Medical University from January 2016 to December 2020 were analyzed retrospectively. All pediatric patients were diagnosed by whole exome sequencing, and the genotype characteristics of the children were analyzed. Results: Among 56 children with monogenic nephrolithiasis, there were 39 males and 17 females, with an average age of 4 years (range, 5 months to 14 years). A total of 11 genes were found to have mutations, including 7 autosomal recessive genes, 1 X-linked recessive gene, and 3 genes with both recessive and dominant, of which HOGA1 gene mutation was the most common (16 cases, 28.6%), followed by AGXT gene (15 cases, 26.8%), SLC3A1 gene (6 cases, 10.7%), SLC7A9 gene (5 cases, 8.9%) and GRHPR gene (5 cases, 8.9%). The mutation types included nonsense mutations, frameshift mutations and splicing mutations, with 14 novel mutations. Genes such as AGXT, GRHPR and HOGA1 have hotspot mutations or hotspot mutation regions, which are c. 815-816 insGA and c. 33dupC mutation, c.864-865delTG mutation and c. 834-834+1 mutation region; SLC3A1 and SLC7A9 genes had 9 novel mutations, but no hotspot mutation or hotspot regions were found. Conclusion: Monogenic nephrolithiasis is rare and mostly autosomal recessive in Chinese children, with mutations in the causative genes HOGA1, AGXT, SLC3A1,SLC7A9 and GRHPR. AGXT, GRHPR and HOGA1 genes have hotspot mutations or hotspot mutation regions, and mutations may have ethnic differences.

Objective: To analyze the association of waist circumference, BMI, waist-hip ratio, waist-height ratio, calf circumference and waist-calf circumference ratio (WCR) with depression risk in centenarians in Hainan province. Methods: A total of 1 002 centenarians in Hainan were selected by cluster sampling. GDS-15 was used to investigate the depression. Multivariate linear regression and logistic regression analyses were conducted to evaluate the correlation between anthropometric indicators and depression risk. Restricted cubic spline was used to analyze and visualize the linear relationship. Results: After adjusting demographic characteristics (gender, age, ethnic group, marital status, educational level and type of residence) and lifestyle (smoking and drinking), the standard ß of BMI, WC, WHR, WHtR, calf circumference and WCR associated with GDS-15 were -0.069, -0.032,0.009, -0.009, -0.099 and 0.060, respectively, and the P values of BMI and calf circumference were <0.05. With the increase of calf circumference, the risk of depression decreased, OR value was 0.94 (95% CI:0.90-0.98), and after adjustment, the results were still significant. Classified variable analysis indicated with the decrease of calf circumference and the increase of WCR, the risk of depression increased gradually, the trend P values were 0.038 and 0.042, respectively. Conclusion: Central obesity (waist circumference and WCR) and periphery obesity (calf circumference) have differed effects on depression in centenarians, and increased calf circumference is a protective factor for depression in female centenarians, attention should be paid to the mental health of the elderly women with lower calf circumference.

OBJECTIVES: Hypertension is a growing health concern in people living with HIV (PLWH). However, association between HIV infection and hypertension is equivocal. METHODS: In all, 1472 PLWH and 2944 HIV-negative individuals frequency-matched by age and sex were derived from the baseline survey of Comparative HIV and Aging Research in Taizhou (CHART), China. Prehypertension was defined as systolic blood pressure (BP) of 120-139 mmHg and/or diastolic blood pressure of 80-89 mmHg. RESULTS: Despite the fact that prevalence of hypertension was overall lower among PLWH than among HIV-negative people (21.1% vs. 29.1%, P < 0.001), it was similar at ages 18-29 (7.6% vs. 8.5%) and 30-44 years (17.1% vs. 18.5%) but significantly lower in PLWH at ages 45-59 (26.1% vs. 40.7%) and 60-75 years (37.1% vs. 57.3%). Prehypertension prevalence was consistently higher in PLWH across all age groups. In the model adjusting for traditional risk factors, HIV infection was associated with hypertension (adjusted odds ratio [aOR] = 1.27, 95% confidence interval: 1.04-1.55) and prehypertension (aOR = 1.77, 95% CI: 1.51-2.08), and attenuated after additional adjustment for abdominal obesity. Age-stratified analysis showed that these associations of HIV with hypertension were observed at ages 18-29 and 30-44 years and associations with prehypertension were observed at ages 18-29, 30-44 and 45-59 years only. Years since HIV diagnosis and stavudine use were the HIV-specific factors independently associated with hypertension or/and prehypertension. CONCLUSIONS: HIV infection is independently associated with prehypertension and hypertension especially at younger ages, and this risk may increase as treatment becomes prolonged. Our findings reinforce the urgent necessity for active BP screening and control strategies be adopted for PLWH in China.

OBJECTIVE: To investigate the prevalence and risk factors of Blastocystis hominis infections among AIDS patients in Nanchang City. METHODS: A cross-sectional questionnaire survey was conducted among AIDS patients in Nanchang City during the period between May and September, 2016. B. hominis infection was detected in patients'stool samples using a PCR assay, and the CD4+ T cell count was measured in subjects'blood samples. In addition, the risk factors of B. hominis infection in AIDS patients were identified using univariate and multivariate logistic regression analyses. RESULTS: A survey was conducted in Nanchang City from May to September 2016. A total of 505 AIDS patients were investigated, and the prevalence of B. hominis infection was 4.16%. Univariate analysis revealed that B. hominis infection correlated with the occupation (χ2 = 8.595, P = 0.049), education level (χ2 = 14.494, P = 0.001), type of daily drinking water (χ2 = 10.750, P = 0.020), root of HIV infections (χ2 = 8.755, P = 0.026) and receiving anti-HIV therapy (χ2 = 23.083, P = 0.001) among AIDS patients, and multivariate logistic regression analysis identified daily direct drinking of tap water as a risk factor of B. hominis infections [odds ratio (OR) = 7.988, 95% confidential interval (CI): (1.160, 55.004)] and anti-HIV therapy as a protective factor of B. hominis infection [OR = 0.183, 95% CI: (0.049, 0.685)]. CONCLUSIONS: The prevalence of B. hominis is 4.16% among AIDS patients in Nanchang City. Daily direct drinking of tap water is a risk factor, and anti-HIV therapy is a protective factor of B. hominis infection among AIDS patients living in Nanchang City.
