Sex Differences in Dietary Patterns of Adults and Their Associations with the Double Burden of Malnutrition: A Population-Based National Survey in the Philippines

A dietary pattern transition is a risk factor for the double burden of malnutrition (DBM), but related information is limited. This study aimed to identify sex differences in dietary patterns of adults in a low–middle income country and to examine their association with DBM. A total of 8957 adults (4465 men and 4492 non-pregnant and non-lactating women) who participated in the 2013 Philippine National Nutrition Survey were included in the analysis. Logistic regression models were formulated to investigate the relationship between dietary patterns and DBM. The factor analysis derived seven dietary patterns for males and six patterns for females. Results showed that approximately 30% of Filipino adults suffered from DBM. The rice pattern was associated with lower odds of DBM for males only. The meat and sugar pattern in males and the protein-rich foods, cereal, and sugar pattern in females decreased DBM likelihood. An inverse relationship was observed for the vegetables and corn patterns, wherein females had an increased risk for DBM. Our findings suggest that rice-based and meat-containing patterns could play protective roles in DBM development among adults in the Philippines. Understanding sex-specific dietary patterns can be utilized to guide public health nutrition interventions in the prevention of malnutrition in all its forms.     

Biomedical Indicators of Patients with Non-Puerperal Mastitis: A Retrospective Study

Background: Non-puerperal mastitis (NPM), a recurrent chronic inflammation of non-lactating breast, often proves tremendous difficulty in treatment, and it may give rise to its complicated symptoms and unclear etiology. Furthermore, the clinical morbidity rate of NPM has been increasing in recent years. Methods: Overall, 284 patients diagnosed with NPM were consecutively recruited as cases in this study, and patients with benign breast disease (n = 1128) were enrolled as control. The clinical, biomedical, and pathological indicators were analyzed. Univariate and multivariate logistic analysis were used to distinguish risks between NPM and benign breast mass patients. Furthermore, according to the pathological characteristics, the patients of NPM were classified into two subgroups: mammary duct ectasia (MDE) and granulomatous lobular mastitis (GLM). The differences of biomedical indicators between MDE and GLM groups were also analyzed. Results: Compared with benign breast mass group, the level of high-density lipoprotein (HDL-C) significantly decreased, while lipoprotein(a) (Lp(a)) and blood glucose (GLU) both increased in NPM group. According to univariate and multivariate logistic analysis, the onset age and HDL-C were generally decreased, while Lp(a) and GLU were increased in NPM group. The onset age, HDL-C, Lp(a), and GLU were modeled to distinguish NPM and benign breast mass. Significant differences were also observed between MDE and GLM patients in biomedical indicators, such as lipoprotein(a) (Lp(a)), lactate dehydrogenase (LDH), creatine kinase (CK), total cholesterol (TC), and so on. Conclusions: Our results indicated for the first time that biomarkers were associated with NPM. The biomedical indicators involved in lipid metabolism might be important factors in the development and treatment of NPM. In addition, MDE and GLM are two diseases with different inflammatory states of NPM. These findings would be helpful for a better understanding of NPM and give us some insights to develop new diagnostic and therapeutic strategies.

Safety and effectiveness of neoadjuvant immunotherapy combined with chemotherapy followed by surgical resection in patients with stage I–IIIA small-cell lung cancer: a retrospective single-arm clinical trial

BackgroundImmunotherapy, chemotherapy and surgery all have significant roles in the management of small-cell lung cancer (SCLC). Neoadjuvant immunotherapy combined with chemotherapy followed by surgery has shown encouraging efficacy for resectable SCLC with a good tolerability and considerable survival benefit. However, there are still few data on whether surgery for stage I–IIIA SCLC can be performed after immunotherapy with chemotherapy. Therefore, we investigated the safety and effectiveness of neoadjuvant immunotherapy combined with chemotherapy followed by surgery in patients with stage I–IIIA SCLC in the hope of adding new ideas to the treatment of SCLC.MethodsThe study group comprised 19 patients with stage I–IIIA SCLC who received neoadjuvant immunotherapy and chemotherapy between 2019 and 2021. Patients received 2–4 cycles of immunotherapy combined with platinum-containing dual-drug chemotherapy (platinum + paclitaxel) before surgery. Imaging evaluation was performed every two cycles until surgery. Tumor response to neoadjuvant therapy, neoadjuvant treatment related adverse events, perioperative and postoperative complications, surgical resection rate, and degree of tumor regression were evaluated. We obtained follow-up data from the patients’ regular examination or treatment in hospital. If we can’t complete it, contacting patients by telephone or WeChat would be adopted by us. The follow-up was not terminated until 3 months after surgery.ResultsThe objective response rate (ORR) was 84.2% (16/19), and no patients had progressive disease (PD). Of the 10 patients who underwent surgery, and approximately 9 (90.0%) had R0 resection. There were no perioperative deaths, and 1 case of pyothorax. The rate of pathological complete remission (pCR) and major pathological response (MPR) was 30.0% (3/10), and 40.0% (4/10) respectively. Grade 3–4 adverse reactions comprised 1 case of anemia and 1 case of constipation.ConclusionsNeoadjuvant immunotherapy combined with chemotherapy followed by surgical resection for patients with stage I–IIIA SCLC is effective and safe with a high ORR and MPR rate, as well as a high R0 resection rate and a tolerable toxicity profile. Whether this regimen gives a survival benefit should be confirmed by further follow-up and larger, randomized controlled trials are required to confirm our findings.     

Lactate promotes vascular smooth muscle cell switch to a synthetic phenotype by inhibiting miR-23b expression

Recent research indicates that lactate promotes the switching of vascular smooth muscle cells (VSMCs) to a synthetic phenotype, which has been implicated in various vascular diseases. This study aimed to investigate the effects of lactate on the VSMC phenotype switch and the underlying mechanism. The CCK-8 method was used to assess cell viability. The microRNAs and mRNAs levels were evaluated using quantitative PCR. Targets of microRNA were predicted using online tools and confirmed using a luciferase reporter assay. We found that lactate promoted the switch of VSMCs to a synthetic phenotype, as evidenced by an increase in VSMC proliferation, mitochondrial activity, migration, and synthesis but a decrease in VSMC apoptosis. Lactate inhibited miR-23b expression in VSMCs, and miR-23b inhibited VSMC''s switch to the synthetic phenotype. Lactate modulated the VSMC phenotype through downregulation of miR-23b expression, suggesting that overexpression of miR-23b using a miR-23b mimic attenuated the effects of lactate on VSMC phenotype modulation. Moreover, we discovered that SMAD family member 3 (SMAD3) was the target of miR-23b in regulating VSMC phenotype. Further findings suggested that lactate promotes VSMC switch to synthetic phenotype by targeting SMAD3 and downregulating miR-23b. These findings suggest that correcting the dysregulation of miR-23b/SMAD3 or lactate metabolism is a potential treatment for vascular diseases.     

Long‐term outcome of cerebral amyloid angiopathy‐related hemorrhage

ObjectThe long‐term functional outcome of cerebral amyloid angiopathy‐related hemorrhage (CAAH) patients is unclear. We sought to assess the long‐term functional outcome of CAAH and determine the prognostic factors associated with unfavorable outcomes.MethodsWe enrolled consecutive CAAH patients from 2014 to 2020 in this observational study. Baseline characteristics and clinical outcomes were presented. Multivariable logistic regression analysis was performed to identify the prognostic factors associated with long‐term outcome.ResultsAmong the 141 CAAH patients, 76 (53.9%) achieved favorable outcomes and 28 (19.9%) of them died at 1‐year follow‐up. For the longer‐term follow‐up with a median observation time of 19.0 (interquartile range, 12.0–26.5) months, 71 (50.4%) patients obtained favorable outcomes while 33 (23.4%) died. GCS on admission (OR, 0.109; 95% CI, 0.021–0.556; p = 0.008), recurrence of ICH (OR, 2923.687; 95% CI, 6.282–1360730.14; p = 0.011), WML grade 3–4 (OR, 31.007; 95% CI, 1.041–923.573; p = 0.047), severe central atrophy (OR, 4220.303; 95% CI, 9.135–1949674.84; p = 0.008) assessed by CT was identified as independent predictors for long‐term outcome.InterpretationNearly 50% of CAAH patients achieved favorable outcomes at long‐term follow‐up. GCS, recurrence of ICH, WML grade and cerebral atrophy were identified as independent prognostic factors of long‐term outcome.
