The COVID-19 pandemic has rapidly become a major challenge for global health care systems and affected other priorities such as the utilization of population-based cancer screening services. We sought to examine to what extent the COVID-19 pandemic has affected cancer screening utilization in Taiwan, even the use of inreach and outreach screening services for different types of cancer screening and different regions.Using nationwide cervical, breast, colorectal and oral cancer screening data, the percentage changes in screening participants at inreach and outreach services were calculated and compared between January to April 2020 (COVID-19 pandemic) and January to April 2019.The average percentage change declined from 15% to 40% for cervical, breast, and colorectal cancer screening, with a nearly 50% decline in oral cancer screening. There was a greater preference for breast and colorectal cancer screening outreach services, which had greater accessibility and declined less than inreach services in most regions. The screening utilization varied in different regions, especially in eastern Taiwan where the less convenient transportation and lower risk of COVID-19 transmission had a positive change on four types of cancer screening outreach services.The COVID-19 pandemic may have had an effect not only in the utilization of different types of cancer screening but also in the preference between inreach and outreach services, and even in variations in screening services in different regions.
Mitigation strategies of the coronavirus disease 2019 (COVID-19) pandemic have been greatly hindered by the continuous emergence of SARS-CoV-2 variants. New sensitive, rapid diagnostic tests for the wide-spectrum detection of viral variants are needed. We generated a panel of 41 monoclonal antibodies against the SARS-CoV-2 nucleocapsid protein (NP) by using mice hybridoma techniques. Of these mAbs, nine exhibited high binding activities and were applied in latex-based lateral flow immunoassays (LFIAs). The LFIAs utilizing NP-mAb-7 and -40 had the best sensitivity and lowest limit of detection: 8 pg for purified NP and 625 TCID50/mL for the authentic virus (hCoV-19/Taiwan/4/2020). The specificity tests showed that the NP-mAb-40/7 LFIA strips did not cross-react with five human coronavirus strains or 20 other common respiratory pathogens. Importantly, we found that 10 NP mutants, including alpha (B.1.1.7), beta (B.1.351), gamma (P.1), and delta (B.1.617.2) variants, could be detected by NP-mAb-40/7 LFIA strips. A clinical study (n = 60) of the NP-mAb-40/7 LFIA strips demonstrated a specificity of 100% and sensitivity of 90% in infected individuals with cycle threshold (Ct) values < 29.5. These anti-NP mAbs have strong potential for use in the clinical detection of SARS-CoV-2 infection, whether the virus is wild-type or a variant of concern.
Purpose:The purpose of this study was to compare the differences in myopic control effects between orthokeratology (OK) contact lenses and defocus incorporated multiple segments (DIMS) spectacle lenses.Methods: A retrospective cohort study was conducted that included patients who had received OK lens, DIMS spectacle lens or single-vision spectacle treatments.A total of 54 eyes from 27 individuals, 38 eyes from 19 individuals and 42 eyes from 21 individuals were enrolled into the OK lens, DIMS and control groups, respectively.The primary outcomes were the changes in the spherical equivalent refraction (SER) and axial length (AXL) among the groups.A repeated-measure ANCOVA was adopted to calculate the SER progression and AXL elongation of the OK lens group compared with the DIMS group. Results:The difference in the SER progression was clinically non-significant in the OK lens group compared with the DIMS and control groups (P = 0.001).The total AXL elongation results were similar between the OK lens and DIMS groups, but these were lower than in the control group (P = 0.005).The repeated-measure ANCOVA revealed that the SER progression difference during the study interval was clinically non-significant in the OK lens group when compared with the DIMS group (P = 0.028).The AXL elongation results between the OK lens and DIMS populations did not illustrate a significant difference (P = 0.607).In a subgroup analysis of moderate astigmatism, better AXL control was observed in the DIMS subgroup compared with the OK lens subgroup (P = 0.016). Conclusions:The OK lens demonstrated a clinically non-significant effect on the SER and AXL controls compared with the DIMS spectacle lens.
Studies exploring the mediating and predictive factors of anxiety and depression for prostate cancer patients in Eastern countries are scant. Guided by the transactional model of stress and coping, this study determined the predictors and mediators of anxiety and depression in prostate cancer patients. The participants comprised 115 prostate cancer patients and 91 partners. The patients and partners completed questionnaires regarding physical symptoms, disease appraisals, coping behaviours, anxiety and depression in the period before confirmation of treatment decisions and 1, 3, 6 and 12 months after treatment. The results revealed that partner anxiety engendered a stressful situation and aggravated patient anxiety. Patients' threat appraisals and affective-oriented coping behaviours mediated the relationships between their anxiety levels and those of their partners. The patients' most recent prostate-specific antigen (PSA) levels and hormonal symptoms were key predictors of their anxiety and depression levels. The patients' harm appraisals mediated the relationships between their most recent PSA levels and hormonal symptoms and depression. Their threat appraisals and affective-oriented coping behaviours mediated the relationships between their hormonal symptoms and anxiety and depression. To manage those key factors, reframing, appraising disease and improving coping behaviours may reduce anxiety and depression levels in prostate cancer patients.
Extracorporeal membrane oxygenation (ECMO) is one of the common invasive treatments for the care of critically ill patients with heart failure, respiratory failure, or both. There are two modes of ECMO, namely, veno-venous (VV) and veno-arterial (VA), which have different indications, survival rates, and incidences of complications. This study’s aim was to examine whether depression status differed between patients who had received VV-ECMO or VA-ECMO and had been discharged from the hospital. This was a descriptive, cross-sectional, and correlational study of patients who had been discharged from the hospital at least one month after receiving ECMO at a medical center in northern Taiwan from June 2006 to June 2020 (N = 142). Participants were recruited via convenience and quota sampling. Data were collected in the cardiovascular outpatient department between October 2015–October 2016 (n = 52) and September 2019–August 2020 (n = 90). Participants completed the Hospital Anxiety and Depression Scale–Depression (HADS-D) as a measure of depression status. Post-discharge depression scores for patients who received VV-ECMO (n = 67) was significantly higher (p = 0.018) compared with participants who received VA-ECMO (n = 75). In addition, the mode of ECMO was a predictor of post-discharge depression (p = 0.008) for participants who received VV-ECMO. This study concluded that patients who received VV-ECMO may require greater mental health support. Healthcare professionals should establish a psychological clinical care pathway evaluated by multiple healthcare professionals.
Little is known regarding the short-term quality of life (QoL) and predictive factors for QoL after esophagectomy for cancer in Eastern countries.The aims of this study were to assess QoL and symptoms within 1 and 6 months after surgery for esophageal cancer (EC) and to identify factors predictive of QoL within 6 months after esophagectomy in Taiwan.A longitudinal, prospective design was used, where convenience samples of 99 patients who had undergone esophagectomy for cancer were recruited from 2 medical centers in northern Taiwan. All participants responded to a questionnaire with a QLQ-C30 (Quality of Life Questionnaire-Cancer) core and a QLQ-OES18 (esophageal module of the European Organization for Research and Treatment [EORTC] QLQ-C30) module in structured interviews at baseline and 1 and 6 months after surgery.The results showed significant decline in social function and global QoL; fatigue, insomnia, eating problems, reflux, and dry mouth were major problems within 6 months. Body mass index, body weight loss before surgery, activity performance status, and anastomosis site showed no significant association with the function and symptom aspect of QoL. Surgical complications, advanced cancer, neoadjuvant therapy before surgery, and tumor location other than at the EC junction had significant deleterious effects on several aspects of QoL.This study describes the demographics of EC and short-term changes in QoL and also the predictive impact factor for QoL after surgery for EC.Knowledge of risk factors for poor postoperative QoL would be useful for health providers in detecting and prioritizing problems and treatment options in a busy clinical site.
