ObjectivePlasma dipeptidyl peptidase-4 (DPP4) levels were significantly lower in patients with colorectal and liver cancers, and animal studies also showed DPP4 inhibitors (DPP4is) have procarcinogenic effects in colorectal cancer. Until now, whether DPP4is therapy affects the progression of liver cancer and colorectal cancer in patients with T2DM has not been well investigated. We investigated the association between cumulative defined daily dose (cDDD) of DPP4is exposure and risks of liver and colorectal cancers in patients with type 2 diabetes.Materials and MethodsWe identified 268,520 patients with diabetes receiving DPP4is as second-line agents between March 1, 2009, and December 31, 2013, from Taiwan’s National Health Insurance Research Database, Taiwan Cancer Registry, and National Death Registry of Taiwan. The amount of DPP4is were divided into three groups (low, medium, and high) based on the interquartile range of the cDDD of the DPP4is.ResultsThe data showed that the low cDDD of DPP-4is was associated with a reducing risk of colorectal cancer [adjusted odds ratio (OR), 0.49; 95% CI, 0.32–0.75; P=0.001]. However, the high cDDD of DPP-4is was associated with an increasing risk of colorectal cancer (adjusted OR, 1.86; 95% CI, 1.32–2.61; P&lt;0.001). No association between DPP4is use and liver cancer risk was observed.ConclusionsThis nested case study revealed a J-shaped association between the cDDD of DPP-4is and colorectal cancer risk, but not liver cancer risk. Therefore, the effects of long-term DPP4is use on colorectal cancer risk warrant further study.

Pericardial effusion is a common finding in advanced-stage lung cancer. The presence of malignant cells or drainage of exudate effusion in the pericardial space may cause symptoms of dyspnea, pleuritic chest pain, and syncope. In addition to the difficulty physicians face in the detection and diagnosis of malignant pericardial effusion, treatment may be challenging considering the cancer prognosis and cardiovascular stability of the patient. Despite the availability of several treatment modalities for malignant pericardial effusion, including chemotherapy and surgery, patients with lung cancer historically present with poor prognoses. In addition to lung adenocarcinoma with malignant pericardial effusion, this case was complicated by COVID-19 and malignancy-associated obstructive pneumonia. We present a case of a 64-year-old woman with advanced non-small cell lung carcinoma (NSCLC) with malignant pericardial effusion who, despite testing positive for COVID-19 and having obstructive pneumonia, had favorable outcomes following systemic therapy with combined chemo-immunotherapy.

BackgroundEndoscopic thyroidectomy is widely accepted for its advantages. However, implant metastasis remains a significant complication of endoscopic thyroidectomy.MethodsThis is the first report of breast implantation diagnosed with poorly differentiated thyroid carcinoma following endoscopic thyroidectomy.ResultsWe present a case of a 35-year-old woman who was initially diagnosed with a 3.0 cm conventional papillary thyroid carcinoma after endoscopic thyroidectomy via total areola. Two years later, she was reported to have recurring poorly differentiated thyroid carcinoma in the right areola. Implantation after endoscopic thyroidectomy is rare, and even rarer is dedifferentiated papillary thyroid carcinoma around the implant site.ConclusionsStringently evaluated endoscopic surgery indications, appropriate preoperative evaluation, meticulous surgical technique, and adequate protective measures can significantly reduce the incidence of local implantation or recurrence.

ObjectiveTo evaluate the rate of, reasons for, and predictors of unplanned reoperation after craniotomy for glioma in a single-institution consecutive series.MethodsPatients who underwent glioma resection at our hospital from 2015 to 2021 were included (n=1563). Multivariate logistic regression was used to examine the predictors of early unplanned cranial reoperation. The predictors that were screened included patient age, sex, tumor properties, blood loss, blood pressure and antiplatelets drugs usage.ResultsA total of 3.6% (56/1563) of the patients underwent an early unplanned reoperation after craniotomy for glioma. The reasons for early unplanned reoperation were brain edema (48.2%), cerebral infarction (33.9%) and hemorrhage (17.9%). The predictors of early unplanned reoperation were WHO grade III-IV, peritumoral edema ≥1 cm, subtotal resection, arterial/venous involvement and elevation in blood pressure ≥50 mmHg.ConclusionsGlioma properties and blood pressure management are decisive predictors of early unplanned reoperation for glioma resection. The authors provide a nuanced discussion regarding early unplanned reoperations and perioperative process improvement as a quality indicator for glioma patient populations.

Background:Juvenile myelomonocytic leukemia (JMML), which is predominantly found in infants, is a clonal abnormality of pluripotent hematopoietic stem cells and presents with the symptoms of both myeloproliferative tumors and myelodysplastic syndromes. Estimates have shown that ~20 cases of JMML occur annually in Japan. Ornithine transcarbamylase deficiency (OTCD), the most common among all urea cycle disorders (UCDs), occurs in 1 of 80,000 people in Japan.Case PresentationA 10-month-old infant who had fever, vomiting, and diarrhea for 2 days was referred to our hospital for the following abnormalities in blood tests: white blood cell count, 48,200/μL; hemoglobin, 9.0 g/dL; and platelet count, 135,000/μL. Bone marrow examination showed a nucleated cell count of 396,000/mm3 and blast cell count of 5.0%, as well as decreased mature granulocyte count and slightly myeloperoxidase stain-negative blasts but no monoclonal cell proliferation on May–Giemsa staining. Colony assay showed the proliferation of spontaneous colony and high sensitivity to granulocyte-macrophage colony-stimulating factor. Genetic analysis of peripheral blood mononuclear cells showed that the patient was positive for neuroblastoma RAS (NRAS) mutation. The patient was ultimately diagnosed with JMML. Approximately 170 days after his first hematopoietic stem cell transplantation (HSCT), the patient's JMML relapsed. Shortly after the recurrence, nausea, vomiting, hyperventilation, and decreased vitality were observed, followed by a decrease in the level of consciousness. The patient's ammonia level was 472 μmol/L. A test for seven different genetic mutations for the UCD showed the presence of c. 119G&gt;A (amino acid change p. Arg40His). As such, late-onset OTCD was added to his diagnosis. Administration of sodium phenylacetate, l-arginine hydrochloride, and carnitine was continued following the diagnosis of OTCD, after which hyperammonemia was not observed. Regarding JMML relapse, HSCT was performed on day 405 after the first transplantation.ConclusionHyperammonemia should be considered a differential diagnosis when unexplained and non-specific symptoms occur during the treatment of hematologic malignancies. Patients should be tested for UCD as a cause of hyperammonemia, and treatment for hyperammonemia should be continued until the cause is identified. The patient shows normal developmental progress, has an intact neurological status, and has not experienced another hyperammonemia attack. His JMML has remained in remission for over 3 years.

ObjectiveUsing multivariate statistics and social network analysis techniques, we present a realistic and intuitive visualization of the research hotspots and development trends of vitamin D in children.MethodsThe Medical Subject Headings (MeSH) term “vitamin D” was used to search all the publications (the study subjects were 0–18 years old) included in PubMed by time period. The subject terms for each development stage were extracted, the high-frequency subject terms were extracted using the Bibliographic Items Co-occurrence Matrix Builder (BICOMB), and a core subject term co-occurrence matrix was established. The Netdraw function of Ucinet 6.0 software was used to complete the social network drawing of the core subject term co-occurrence matrix to form a co-word network diagram composed of core subject terms.ResultsPrior to 1979, there were 890 papers with 1,899 core subject terms; from 2010 to 2020, there were 3,773 papers with 12,682 core subject terms. Before 1979, the research direction of vitamin D in children focused on vitamin D in the classical regulation of calcium and phosphorus metabolism. From 1980 to 1989, studies focused on vitamin D metabolites and therapeutic drugs such as “calcitriol” and “calcifediol.” From 1990 to 1999, studies focused on “calcitriol” and its association with “psoriasis,” “chronic renal failure,” and “dermatological drugs.” From 2000 to 2009, studies focused on “vitamin D” and “vitamin D deficiency.” From 2010 to 2020, studies focused on “vitamin D3” and its association with “vitamins,” “bone mineral density protectants,” “asthma,” “obesity,” “pregnancy complications” and “fetal blood.”ConclusionSince 2010, the research direction of vitamin D in children has been growing rapidly, and the overall development trend is good. Studies extend from the study of the skeletal effect of vitamin D to the study of its extraskeletal effect and the investigation of mechanisms of its association with related diseases.

Published: May 2022

IntroductionYounger age at diagnosis is a risk factor for poor health-related quality of life (HRQOL) in long-term breast cancer survivors. However, few studies have specifically addressed HRQOL in young adults with breast cancer (i.e., diagnosed prior to age 40), nor have early changes in HRQOL been fully characterized.MethodsEligible female patients with breast cancer were identified through our local cancer center. To establish HRQOL, patients completed the Functional Assessment of Cancer Therapy-Breast (FACT-B) around diagnosis and 12 months later. Sociodemographic factors, genetic susceptibility to cancer, tumor- and treatment-related factors, and comorbidities (e.g., depression/anxiety) were abstracted from medical records and the local oncology registry. Mixed-effects models were used to identify changes in FACT-B scores during the first year of treatment and to determine whether any demographic/treatment-related factors modulated changes in scores.ResultsHealth-related quality of life in young patients with breast cancer was within normal limits at baseline, with a FACT-B overall well-being score of 108.5 (95% confidence limits [CI] = 103.7, 113.3). Participants reported slight improvements over a 12-month period: FACT-B overall well-being scores increased 6.6 points (95% CI = 2.1, 11.1, p &lt; 0.01), functional well-being improved 3.0 points (95% CI = 2.0, 4.1, p &lt; 0.01), emotional well-being improved 1.9 points (95% CI = 0.9, 2.8, p &lt; 0.01), and physical well-being improved 1.5 points (95% CI = 0.2, 2.8, p = 0.03), on average. Participants with anxiety/depression at baseline reported greater improvements in FACT-B overall well-being (change: 12.9, 95% CI = 6.4, 9.5) and functional well-being (change: 5.2, 95% CI = 3.5, 6.9) than participants who did not have anxiety/depression at baseline (change in FACT-B overall well-being: 4.9, 95% CI = 0.2, 9.7; change in functional well-being: 2.3, 95% CI = 1.1, 3.4). Marital status, reconstructive surgery, and baseline clinical staging were also significantly associated with changes in aspects of HRQOL, although their impact on change was relatively minimal.ConclusionYoung women with breast cancer do not report HRQOL concerns during the first year of treatment. Improvements in HRQOL during the first year of treatment may be attributable to a sense of relief that the cancer is being treated, which, in the short run, may outweigh the negative late effects of treatment.

Published: May 2022

ObjectiveThis article explores the effect of preoperative health education, in the form of animation videos, on postoperative self-reported pain levels and anxiety in femoral fractures.MethodsNinety cases of femoral fracture were divided at random into the oral instruction group, the recorded video group, and the animation video group, with 30 cases in each group. Sociodemographic data were collected the day before surgery. Health education was then offered in one of three ways: orally, using a recorded video, or using an animation video. On days 2, 4, and 7 after surgery, the state-trait anxiety inventory (STAI) and the visual analog scale (VAS) were used to assess postoperative anxiety and pain levels, respectively, in the participants.ResultsAt different time points during the evaluation, total anxiety scores in the animation and recorded video groups were significantly lower than in the oral instruction group (P &lt; 0.01), and the pairwise comparisons indicated statistically significant differences (F = 11.04, 10.06, 10.37, P &lt; 0.01). However, the levels of postoperative pain in the animation and recorded video groups were not significantly different (P &gt; 0.05). STAI scores in the three groups were found to have significant interactions with the measurement time (F = 6.74, P &lt; 0.01). However, there were no apparent interactions between the VAS score and the measurement time (F = 1.31, P &gt; 0.05) in the three groups.ConclusionPreoperative health education with the aid of multimedia is more effective than oral instruction in lowering patients’ postoperative anxiety and pain levels. In addition, animation videos are superior to recorded videos in mitigating postoperative anxiety. Whether the two approaches differ in reducing postoperative pain in bone fractures remains to be further tested.

ObjectiveThis study aimed to investigate the efficacy of repetitive transcranial magnetic stimulation (rTMS) in treating suicidal ideation in patients with mental illness.MethodWe followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Major electronic databases were systematically searched from the time of their inception until July 22, 2021. The primary outcome was the mean change in the scores for suicidal ideation. The secondary outcome was the mean change in depression severity.ResultsTen randomized controlled trials were eligible with 415 participants in the active treatment group (mean age = 53.78 years; mean proportion of women = 54.5%) and 387 participants in the control group (mean age = 55.52 years; mean proportion of women = 51.78%). rTMS significantly reduced suicidal ideation (k = 10, n = 802, Hedges' g = −0.390, 95% confidence interval [CI] = −0.193 to −0.588, p &lt;.001) and severity of depressive symptoms (k = 9, n = 761, Hedges' g = −0.698, 95% CI = −1.023 to −0.372, p &lt; 0.001) in patients with major mental disorders. In the subgroup analysis, rTMS reduced suicidal ideation among patients with non-treatment-resistant depression (non-TRD) (−0.208) but not in those with TRD. rTMS as combination therapy had a larger effect than did monotherapy (−0.500 vs. −0.210). Suicidal ideation significantly reduced in patients receiving more than ten treatment sessions (-0.255). Importantly, the rTMS group showed favorable tolerability without major adverse events.ConclusionThe study showed that rTMS was effective and well-tolerated in reducing suicidal ideation and depression severity in patients with major mental disorders.

BackgroundMore than 200 countries are experiencing the coronavirus disease (COVID-19) pandemic. COVID-19 vaccination strategies have been implemented worldwide, and repeat COVID-19 outbreaks have been seen. The purpose of this study was to investigate the impact of COVID-19 vaccination on the reduction of perceived anxiety and the association between public anxiety and antibody testing intention during the COVID-19 pandemic.MethodsChinese adults aged 18 and over were surveyed using an anonymous online questionnaire in April and May 2021. The questionnaire collected sociodemographic characteristics, vaccination characteristics, perceived anxiety due to COVID-19, and attitudes toward future antibody testing after COVID-19 vaccination. Perceived anxiety was assessed on a visual analog scale (VAS). Multivariate logistic regression analysis was used to determine the factors influencing future antibody detection.ResultsA total of 3,233 people were investigated, 3,209 valid questionnaires were collected, and the response rate was 99.3%. Of the 3,209 respondents, 2,047 were vaccinated, and 1,162 were unvaccinated. There was a significant difference in anxiety levels between vaccinated and unvaccinated respondents (24.9±25.4 vs. 50.0±33.1, respectively). With the local spread of COVID-19 in mainland China, the public anxiety VAS scores increased by 15.4±25.6 (SMD=120%) and 33.8±31.7 (SMD=49%) among vaccinated and unvaccinated respondents, respectively. Of the 2,047 respondents who were vaccinated, 1,626 (79.4%) thought they would accept antibody testing. Those who displayed more anxiety about acquiring COVID-19 disease were more likely to accept COVID-19 antibody testing. If the antibody test results showed protective antibodies, 1,190 (58.1%) were more likely to arrange travel plans in China, while 526 (25.7%) thought they would feel safer traveling abroad.ConclusionCOVID-19 vaccination strategies help reduce public anxiety. However, public anxiety may be elevated as the local transmission of COVID-19 occurs in mainland China, which is usually caused now by imported cases. Those who display more anxiety choose to have antibody testing. Improving the accessibility of COVID-19 antibody tests can help ease public anxiety and enhance the confidence of some people to participate in social activities.

IntroductionThe process of learning begins in childhood and accurate vision can greatly affects a child's learning capacity. It is documented that visual impairment in children can have a significant impact on their performance at school as well as their social interaction and development.ObjectiveThis research aimed to study the impact of refractive corrections on the academic performance of high school children in Lahore.MethodologyA total of 2,000 students with equal distribution of gender, public, private school, and locality were included in the study. All students were screened for defective vision. The academic performance before and after corrections was recorded on the prescribed proforma.ResultsThe prevalence of refractive error was high among the public high schools 244 (59.2%) as compared to the private schools 168 (40.8%). The area-based prevalence was higher among the students in urban settings 255 (62%) while in rural it was 157 (38%). It was found that in the public sector, the average score of academic results before the intervention was 56.39 ± 13.24 which was increased to 60.27 ± 14.94 after the intervention while in the private sector, before the intervention, the average score was 63.53 ± 17.50 which was improved to 67.12 ± 18.48. It was found to be statistically significant at p-value &lt; 0.05.ConclusionA significant impact was observed in the average academic scores of the results after refractive corrections.

BackgroundSeveral preclinical and clinical studies demonstrated a strong correlation between androgen receptor (AR) signaling and bladder tumorigenesis. This study aims to evaluate the prognostic significance of AR expression in metastatic urothelial carcinoma (mUC).MethodsSamples from a phase III trial (LaMB, NCT00949455) which compared maintenance lapatinib versus placebo after completion of first-line platinum-based chemotherapy in patients with HER 1/2-positive mUC of the bladder were collected. Corresponding baseline and follow-up data included patients enrolled in the study and those who screen failed. AR expression was assessed independently by a single pathologist who was blinded to the study. Samples were grouped according to AR expression (negative vs. positive) and correlated with baseline tumor characteristics and survival.ResultsOf the 446 screened samples in the LaMB study, 90 were retrospectively analyzed for AR expression. There were no correlations between AR expression and tumor stage (r = −0.10), tumor grade (r = 0.05) at diagnosis, or subsequent treatment with lapatinib (r = −0.04). The median progression-free survival was 6 months (95% CI, 3.20–6.80) in the AR-negative group and 5 months (95% CI, 3.41–6.59) in the AR-positive group [HR 0.54 (95% CI, 0.31–0.92), p = 0.02]. Similarly, patients with AR-negative disease had more favorable overall survival (OS) with 16 months (95% CI, 6.6–25.4) and 11 months (95% CI, 7.0–15.0) in the AR-positive group [HR 0.55 (95% CI, 0.31–0.98), p = 0.04]. In the multivariate analysis, AR expression was significantly associated with worse OS (p = 0.045).ConclusionsAR expression is a predictor of poor outcome and presents a targetable alteration in patients with mUC.
