Physical function as a predictor of chemotherapy-induced peripheral neuropathy in patients with pancreatic cancer.

BACKGROUND: A growing body of research indicates that poor functional status before chemotherapy may be correlated with the severity of chemotherapy-induced peripheral neuropathy (CIPN) after the neurotoxic treatment. However, little is known about the associations between pre-chemotherapy physical function and CIPN in patients with pancreatic cancer. PURPOSE: To identify the predictors of CIPN in relation to pre-chemotherapy physical function in patients with pancreatic cancer. METHODS: This secondary analysis included data from patients with pancreatic cancer who participated in a longitudinal research study at National Cheng Kung University Hospital, Tainan, Taiwan. Four physical function tests (i.e., grip strength, Timed Up and Go (TUG), 2-minute step test (2MST), and Romberg test) and two questionnaires (The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 [EORTC QLQ-C30] and Chemotherapy-Induced Peripheral Neuropathy Module [CIPN20]) were assessed at baseline (i.e., before first chemotherapy session) and 2-, 3-, 4-, and 6-month follow-up. Multiple linear regression with adjustment for confounding factors was used to assess the associations between the four functional tests at baseline and the CIPN20 total score and individual subscale scores (sensory, motor, and autonomic) at 6-month follow-up. RESULTS: Data from a total of 209 pancreatic cancer patients (mean age: 64.4 years, 54.5% male) were analyzed. The findings showed that the severity of CIPN at 6-month follow-up was significantly associated with the baseline TUG completion time (ß = 0.684, p = 0.003). The TUG completion time was also positively correlated with the 6-month CIPN sensory and autonomic subscales. In addition, a baseline positive Romberg test (ß = 0.525, p = 0.009) was a significant predictor of the severity of motor neuropathy at 6-month follow-up. CONCLUSION: The TUG completion time and positive Romberg test before chemotherapy may be predictive factors of the CIPN severity 6 months after the commencement of chemotherapy. Accordingly, the incorporation of TUG and Romberg tests into the clinical assessment protocol emerges as imperative for individuals diagnosed with pancreatic carcinoma undergoing chemotherapy regimens.

Natural history of pelvic floor disorders before and after hysterectomy for gynaecological cancer.

OBJECTIVE: To investigate the prevalence and severity of pelvic floor disorders (PFD), and the associations between treatment type and PFD, and cancer stage and PFD in patients before and after hysterectomy for gynaecological cancer; and the changes in outcomes over time. DESIGN: Longitudinal cohort study. SETTING: Gynaecological oncology outpatient clinics. POPULATION: Patients undergoing hysterectomy for endometrial, uterine, ovarian or cervical cancer. METHODS: Participants were assessed before, and 6 weeks and 3 months after hysterectomy. Changes over time were analysed using generalised estimating equations or linear mixed models. Associations were analysed using logistic regression models and analyses of variance. MAIN OUTCOME MEASURES: Incontinence Severity Index, Pelvic Floor Distress Inventory-short form (PFDI-20), Female Sexual Function Index. RESULTS: Of 277 eligible patients, 126 participated. Prevalence rates of PFD were high before (urinary incontinence [UI] 66%, faecal incontinence [FI] 12%, sexual inactivity 73%) and after (UI 59%, FI 14%, sexual inactivity 58%) hysterectomy. Receiving adjuvant therapy led to moderate-to-very severe UI 3 months after surgery compared with surgery only (odds ratio 4.98, 95% CI 1.63-15.18). There was no association between treatment type and other PFD, or cancer stage and any PFD. CONCLUSION: Prevalence of PFD was high before and after hysterectomy for gynaecological cancer. Moderate-to-very-severe UI was associated with adjuvant therapy.

Environment contamination and intra-hospital spread of COVID-19 in a tertiary care Hospital in Taiwan.

BACKGROUND: The role of environmental contamination in COVID-19 transmission within hospitals is still of interest due to the significant impact of outbreaks globally. However, there is a scarcity of data regarding the utilization of environmental sampling for informing infection control measures during SARS-CoV-2 outbreaks. METHODS: This retrospective study analyzed incident event investigations conducted at a single center from May 1, 2021, to August 31, 2021. Investigations were initiated following the identification of a COVID-19 confirmed case (referred to as the index case) who had stayed in a hospital area outside the dedicated COVID-19 ward/bed and without specific COVID-19 precautions. Measures to prevent intra-hospital spread included contact tracing, adjusted testing policies, isolation of confirmed cases, quarantine of close contacts, environmental disinfection, and PCR testing of environmental samples. RESULTS: Among the 18 incident events investigated, the index case was a healthcare personnel in 8 events, a patient in 8 events, and a caregiver in 2 events. The median number of confirmed COVID-19 cases within 14 days was 13 (IQR, 7-31) for events with SARS-CoV-2 RNA detected on environmental surfaces, compared to only one (IQR, 1-1.5) for events without surface contamination (P = 0.04). Environmental contamination was independently associated with a higher number of COVID-19 cases (P < 0.001). CONCLUSION: This study highlights environmental contamination as an indicator of the severity of incident events and provides a framework for incident event management, including a protocol for environmental sampling. Implementing these measures can help prevent the spread of COVID-19 within healthcare facilities.

Preventing and controlling intra-hospital spread of COVID-19 in Taiwan - Looking back and moving forward.

COVID-19 has exposed major weaknesses in the healthcare settings. The surge in COVID-19 cases increases the demands of health care, endangers vulnerable patients, and threats occupational safety. In contrast to a hospital outbreak of SARS leading to a whole hospital quarantined, at least 54 hospital outbreaks following a COVID-19 surge in the community were controlled by strengthened infection prevention and control measures for preventing transmission from community to hospitals as well as within hospitals. Access control measures include establishing triage, epidemic clinics, and outdoor quarantine stations. Visitor access restriction is applied to inpatients to limit the number of visitors. Health monitoring and surveillance is applied to healthcare personnel, including self-reporting travel declaration, temperature, predefined symptoms, and test results. Isolation of the confirmed cases during the contagious period and quarantine of the close contacts during the incubation period are critical for containment. The target populations and frequency of SARS-CoV-2 PCR and rapid antigen testing depend on the level of transmission. Case investigation and contact tracing should be comprehensive to identify the close contacts to prevent further transmission. These facility-based infection prevention and control strategies help reduce hospital transmission of SARS-CoV-2 to a minimum in Taiwan.

Findings of an Extraluminal Leiomyosarcoma of the Urinary Bladder in a Dog.

A 9 yr old male miniature poodle presented with acute diarrhea, vomiting, and a distended abdomen. A large and firm mass was palpated in the caudal abdomen. Radiography showed a large soft-tissue mass in the mid ventral abdomen. The mass was mildly contrast-enhancing and in contact with the right cranial aspect of the bladder on computed tomography. The mass was heterogeneous with minimal blood flow on Doppler examination. Surgery confirmed its origin of the urinary bladder, and it was diagnosed leiomyosarcoma on pathology. This is the first report of extraluminal leiomyosarcoma of the bladder wall with imaging characteristics using various modalities.

Higher serologic responses of early syphilis to single-dose benzathine penicillin G plus doxycycline versus single-dose benzathine penicillin G alone among people with HIV.

BACKGROUND: Single-dose benzathine penicillin G (BPG) is the preferred therapy for early syphilis, but poorer serologic responses have been observed among people with HIV (PWH). No enhanced regimen has previously been shown to improve serologic outcomes of early syphilis. METHODS: We conducted a retrospective study to compare the treatment responses to single-dose BPG combined with 7-day doxycycline versus BPG alone in PWH who presented with early syphilis. Rapid plasma reagin (RPR) titers were determined every 3-6 months for all included PWH. Serologic response was defined as at least a fourfold decline in RPR titers at month 12. RESULTS: During January 2018 to March 2022, 223 PWH with 307 episodes of early syphilis received single-dose BPG plus doxycycline and 347 PWH with 391 episodes received BPG alone. The median age was 36 years and baseline CD4 count was 600 cells/mm3. In the intention-to-treat with last-observation-carried-forward analysis, PWH receiving BPG plus doxycycline had a significantly higher serologic response rate at 12 months of treatment than those receiving BPG alone (79.5% vs 70.3%, respectively; P= .006). The factors associated with 12-month serologic response were RPR titer (per 1-log2 increase, adjusted odds ratio [AOR], 1.25; 95% CI, 1.15-1.35) and receipt of BPG plus doxycycline (AOR, 1.71; 95% CI, 1.20-2.46). In the subgroup analyses, BPG plus doxycycline was consistently associated with a better serologic response than BPG alone at month 12. CONCLUSIONS: Among PWH with early syphilis, single-dose BPG plus doxycycline achieved higher serologic responses than BPG alone during a 12-month follow-up period.

A Randomized Clinical Trial of 1-Dose vs Accelerated 2-Dose Schedule for Hepatitis A Virus (HAV) Revaccination Among People With Human Immunodeficiency Virus Who Were Nonresponders or Had Seroreversion After Primary HAV Vaccination.

BACKGROUND: For people with human immunodeficiency virus (PWH) who have no serological responses to their primary hepatitis A virus (HAV) vaccination or have seroreversion after successful primary vaccination, the optimal revaccination strategy remains unclear. METHODS: In this open-label, randomized clinical trial, PWH who tested negative for anti-HAV antibodies after receiving a standard 2-dose series of primary HAV vaccination were enrolled and assigned in a 1:1 ratio to receive either 1 dose (the 1-dose group) or 2 doses of HAV vaccine administered 4 weeks apart (the 2-dose group). Serological response rates and anti-HAV antibody titers were compared at weeks 24 and 48. RESULTS: Of the 153 participants (77 in the 1-dose group and 76 in the 2-dose group), the overall serological response rates at week 48 after revaccination were similar between the 2 groups (2- vs 1-dose, 80.2% vs 71.4%, P = .20). However, anti-HAV antibody titers were consistently higher in the 2-dose group than in the 1-dose group. In subgroup analysis, PWH who were nonresponders to primary HAV vaccination were significantly more likely to mount a serological response after 2-dose HAV revaccination (68.4% vs 44.1%, P = .038). No severe adverse events were reported throughout the study. CONCLUSIONS: Two-dose HAV revaccination administered 4 weeks apart yielded similar serological responses as 1-dose revaccination among PWH who were nonresponders or had seroreversion after primary HAV vaccination. The 2-dose revaccination schedule generated significantly higher anti-HAV antibody titers and was more likely to elicit serological responses at week 48 among PWH who were nonresponders to primary HAV vaccination.

Treatment responses to integrase strand-transfer inhibitor-containing antiretroviral regimens in combination with short-course rifapentine-based regimens for latent tuberculosis infection among people with HIV.

BACKGROUND: Real-world experience with combinations of short-course rifapentine-based regimens and integrase strand-transfer inhibitor (InSTI)-containing antiretroviral therapy (ART) in management of latent tuberculous infection (LTBI) is limited among people with HIV (PWH). METHODS: From August 2019 to October 2022, PWH receiving 3 months of weekly rifapentine plus isoniazid (3HP) or 1 month of daily rifapentine plus isoniazid (1HP) in combination with ART were included. The primary outcome was virologic response within 12 months after LTBI treatment, and the secondary outcomes included treatment completion rate and safety of LTBI regimens. RESULTS: During the study period, 479 PWH (94.6% male; median age, 43 years) were included: 142 received 1HP and bictegravir (BIC)-containing regimens (1HP/BIC group), 46 1HP and dolutegravir (DTG)-containing regimens (1HP/DTG group), 38 3HP and BIC-containing regimens (3HP/BIC group), 214 3HP and DTG-containing regimens (3HP/DTG group), 17 1HP and other ART regimens (1HP/others group), and 22 3HP/other ART regimens (3HP/others group). In the intention-to-treat analysis, the proportions of PWH maintaining plasma HIV-1 RNA <200 copies/mL within 12 months after LTBI treatment completion were 96.5% (1HP/BIC), 100% (1HP/DTG), 100% (3HP/BIC), 95.8% (3HP/DTG), 100% (1HP/others), and 100% (3HP/others). The overall completion rates were >80% for all treatment groups, whereas >50% of the included PWH experienced any adverse event. LTBI regimens and ART combinations were not associated with virologic response and completion rate. CONCLUSION: Combinations of short-course rifapentine-based regimens and InSTI-containing ART maintained viral suppression for most PWH within 12 months of LTBI treatment completion with low rates of grade 3 or higher adverse events.

Pelvic floor muscle training delivered via telehealth to treat urinary and/or faecal incontinence after gynaecological cancer surgery: a single cohort feasibility study.

PURPOSE: To assess the feasibility and clinical outcomes of telehealth-delivered pelvic floor muscle training (PFMT) for urinary incontinence (UI) and/or faecal incontinence (FI) after gynaecological cancer surgery. METHODS: In this pre-post cohort clinical trial, patients with incontinence after gynaecological cancer surgery underwent a 12-week physiotherapist-supervised telehealth-delivered PFMT program. The intervention involved seven videoconference sessions with real-time feedback from an intra-vaginal biofeedback device and a daily home PFMT program. Feasibility outcomes included recruitment, retention, engagement and adherence rates. Clinical outcomes were assessed at baseline, immediately post-intervention and a 3-month post-intervention using International Consultation on Incontinence questionnaires for UI (ICIQ-UI-SF) and Bowel function (ICIQ-B) and the intra-vaginal biofeedback device. Means and 95%CIs for all time points were analysed using bootstrapping methods. RESULTS: Of the 63 eligible patients, 39 (62%) consented to the study. Three participants did not complete baseline assessment and were not enrolled in the trial. Of the 36 participants who were enrolled, 32 (89%) received the intervention. Retention was 89% (n=32/36). The majority of participants (n=30, 94%) demonstrated high engagement, attending at least six videoconference sessions. Adherence to the daily PFMT program was moderate, with 24 participants (75%) completing five-to-seven PFMT sessions per week during the intervention. All clinical outcomes improved immediately post-intervention; however, the magnitude of these improvements was small. CONCLUSION: Telehealth-delivered PFMT may be feasible to treat incontinence after gynaecological cancer surgery. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: ACTRN12621000880842).

Physical therapy intervention for breast symptoms in lactating women: a randomized controlled trial.

BACKGROUND: Therapeutic ultrasound, education, and massage are the most common physical therapy interventions provided to mothers with breast symptoms. However, there is insufficient evidence on the effectiveness of the combination of these interventions. This study aimed to explore the effects of the combination of therapeutic ultrasound, education, and massage on breast symptoms in lactating women. METHODS: This study was a single-blind randomized controlled trial. Postpartum lactating women aged from 21 to 45 with breast symptoms were recruited and randomly allocated to one of three groups (ultrasound group, sham group, and usual care group). The severity of breast symptoms (pain, redness, lump, general malaise), breast engorgement, breast hardness, body temperature, breast temperature, and milk volume were assessed at baseline (T1), immediately post-intervention (T2), and at 3 months following baseline (T3). RESULTS: A total of 37 participants were included in the study (ultrasound group n = 12; sham group n = 12; usual care n = 13). The severity of breast symptoms (i.e., pain, lump, and general malaise) as well as breast engorgement, were significantly improved in the ultrasound group at T2 when compared to T1, and these improvements were sustained at T3. The severity of breast engorgement was significantly lower in the ultrasound group when compared to the usual care group at T2. However, no statistically significant differences were found between the ultrasound and sham groups for all outcomes at any assessment time points. CONCLUSIONS: Physical therapy interventions may be beneficial in relieving breast symptoms in lactating women. Larger randomized controlled trials are needed to confirm the findings of this study. TRIAL REGISTRATION: ClinicalTrials.gov (NCT04569136); Date of registration: 29/09/2020.

Women's preferences for pelvic floor screening in sport and exercise: a mixed-methods study integrating survey and interview data in Australian women.

OBJECTIVES: One in two women experiencing pelvic floor (PF) symptoms stop playing sport or exercising. The study examines the perspective of women with PF symptoms to inform acceptable screening practices within sport and exercise settings. METHODS: Explanatory, sequential, mixed-methods design. Phase 1: survey of 18-65 years, symptomatic, Australian women (n=4556). Phase 2: semistructured interviews with a subset of survey participants (n=23). Integration occurred through connection of phases (study design, sampling) and joint display of data. RESULTS: Findings are represented in three threads: (1) 'women (not) telling'; a majority of women had told no-one within a sport or exercise setting about their PF symptoms due to shame/embarrassment, lack of pelvic health knowledge and not wanting to initiate the conversation, (2) 'asking women (screening for PF symptoms)'; women endorsed including PF symptom questions within existing sport and exercise screening practices but only when conducted in a respectful and considered manner and (3) 'creating safety'; professionals can assist women to disclose by demonstrating expertise, trustworthiness and competency. If health and exercise professionals are provided with appropriate training, they could raise pelvic health awareness and promote a supportive and safe sport and exercise culture. CONCLUSION: Women with PF symptoms support health and exercise professionals initiating conversations about PF health to normalise the topic, and include PF symptoms among other pre-exercise screening questions. However, women should be informed on the relevance and potential benefits of PF screening prior to commencing. Safe screening practices require building trust by providing information, gaining consent, displaying comfort and genuine interest, and being knowledgeable within one's scope of practice to the provision of advice, exercise modifications and referral as appropriate.

Factors associated with viral rebound among COVID-19 patients receiving oral antivirals.

BACKGROUND: COVID-19 rebound is usually reported among patients experiencing concurrent symptomatic and viral rebound. But longitudinal viral RT-PCR results from early stage to rebound of COVID-19 was less characterized. Further, identifying the factors associated with viral rebound after nirmatrelvir-ritonavir (NMV/r) and molnupiravir may expand understanding of COVID-19 rebound. METHODS: We retrospectively analyzed clinical data and sequential viral RT-PCR results from COVID-19 patients receiving oral antivirals between April and May, 2022. Viral rebound was defined by the degree of viral load increase (ΔCt ≥ 5 units). RESULTS: A total of 58 and 27 COVID-19 patients taking NMV/r and molnupiravir, respectively, were enrolled. Patients receiving NMV/r were younger, had fewer risk factors for disease progression and faster viral clearance rate compared to those receiving molnupiravr (All P < 0.05). The overall proportion of viral rebound (n = 11) was 12.9%, which was more common among patients receiving NMV/r (10 [17.2%] vs. 1 [3.7%], P = 0.16). Of them, 5 patients experienced symptomatic rebound, suggesting the proportion of COVID-19 rebound was 5.9%. The median interval to viral rebound was 5.0 (interquartile range, 2.0-8.0) days after completion of antivirals. Initial lymphopenia (<0.8 × 109/L) was associated with viral rebound among overall population (adjusted odds ratio [aOR], 5.34; 95% confidence interval [CI], 1.33-21.71), and remained significant (aOR, 4.50; 95% CI, 1.05-19.25) even when patients receiving NMV/r were considered. CONCLUSION: Our data suggest viral rebound after oral antivirals may be more commonly observed among lymphopenic individuals in the context of SARS-CoV-2 Omicron BA.2 variant.

Disseminated Mycobacterium chimaera infection in a patient with adult-onset immunodeficiency syndrome: case report.

BACKGROUND: Patients with adult-onset immunodeficiency syndrome due to anti-interferon-γ autoantibodies (AIGAs) are susceptible to disseminated Mycobacterium avium complex (MAC) infections. M. chimaera, a newly identified MAC species, is distinguished from the others due to the reduced virulence. Previous cases of disseminated M. chimaera infection have been linked to cardiothoracic surgery. Reports of disseminated M. chimaera in patients without a history of cardiothoracic surgery are rare. CASE PRESENTATION: A 57-year-old Asian man, previously healthy, presented with fever, dry cough, exertional dyspnea, and decreased appetite. The delayed resolution of pneumonia despite antibiotic treatment prompted further imaging studies and biopsies from the lung and lymph node. The fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) demonstrated intense uptake in lung consolidations and diffuse lymphadenopathy. Cultures of the specimens obtained from sputum, blood, stool, lung tissue, and lymph node grew M. chimaera. Further immunological evaluation disclosed the presence of neutralizing AIGAs, which possibly led to acquired immunodeficiency and disseminated M. chimaera infection. CONCLUSIONS: We herein present the first case of adult-onset immunodeficiency due to AIGAs complicated with disseminated M. chimaera infection. Further immunological evaluation, including AIGAs, may be warranted in otherwise healthy patients who present with disseminated mycobacterial infection.

Experiences of pelvic floor dysfunction and treatment in women with breast cancer: a qualitative study.

PURPOSE: To explore the experiences of women with breast cancer and pelvic floor (PF) dysfunction and the perceived enablers and barriers to uptake of treatment for PF dysfunction during their recovery. METHOD: Purposive sampling was used to recruit 30 women with a past diagnosis of breast cancer and PF dysfunction. Semi-structured interviews were conducted, and data were analysed inductively to identify new concepts in the experiences of PF dysfunction in women with breast cancer and deductively according to the capability, opportunity, motivation and behaviour (COM-B) framework to identify the enablers and barriers to the uptake of treatment for PF dysfunction in women with breast cancer. RESULTS: Participants were aged between 31 and 88 years, diagnosed with stages I-IV breast cancer and experienced either urinary incontinence (n = 24/30, 80%), faecal incontinence (n = 6/30, 20%) or sexual dysfunction (n = 20/30, 67%). They were either resigned to or bothered by their PF dysfunction; bother was exacerbated by embarrassment from experiencing PF symptoms in public. Barriers to accessing treatment for PF dysfunction included a lack of awareness about PF dysfunction following breast cancer treatments and health care professionals not focussing on the management of PF symptoms during cancer treatment. An enabler was their motivation to resume their normal pre-cancer lives. CONCLUSION: Participants in this study reported that there needs to be more awareness about PF dysfunction in women undergoing treatment for breast cancer. They would like to receive information about PF dysfunction prior to starting cancer treatment, be screened for PF dysfunction during cancer treatment and be offered therapies for their PF dysfunction after primary cancer treatment. Therefore, a greater focus on managing PF symptoms by clinicians may be warranted in women with breast cancer.

Physical therapists' experiences and perceptions of antepartum and postpartum care.

BACKGROUND: Little is known about the physical therapists' practice and perceptions toward management of pregnancy/postpartum-related disorders in Taiwan. The aim of this study was to document current practice of physical therapy in antepartum and postpartum care in Taiwan. METHODS: An exploratory, cross-sectional study was conducted in registered physical therapists living in Taiwan. An anonymized online survey was designed, piloted, and advertised widely from March 2020 to March 2021. Data were analyzed using descriptive statistics, Chi square analysis and multivariate logistic regression. RESULTS: Of the 364 respondents, 37.6% had experience of treating pregnant or postpartum women in clinical practice. The most commonly treated pregnancy/postpartum-related disorder in practice was low back pain (61.3%). All respondents reported little to moderate level of confidence in their ability to manage pregnancy/postpartum-related disorder. Being female (p < 0.01); working at a regional hospital (p = 0.01), district hospital or district teaching hospital (p < 0.01), clinic (p = 0.01) or physiotherapy clinic (p = 0.01); and having prior experience of treating antepartum or postpartum women (p < 0.01) were significantly associated with willingness to provide customer-oriented service or health education to patients/clients with pregnancy/postpartum-related disorder after controlling for other confounding variables. The most commonly reported barrier was "lack of available training" (81.3%). CONCLUSION: The majority of participating physical therapists indicated a positive attitude to antepartum and postpartum care but were not confident in management of various pregnancy/postpartum-related disorder in practices. The findings of this study highlight the educational needs related to antepartum and postpartum care in clinical practice for physical therapists in Taiwan.

Serological response after COVID-19 mRNA-1273 booster dose in immunocompromised patients, Taiwan, July to August 2021.

BACKGROUND: Whether immunocompromising conditions affect the immunogenicity of COVID-19 booster vaccination remains a concern, which impedes the vaccination campaign in people most vulnerable to COVID-19-associated morbidity and mortality. We aimed to evaluate the effect of immune dysfunction on immunogenicity of homologous and heterologous prime-boost COVID-19 vaccination. METHODS: Between July and August, 2021, 399 participants were randomized to receive ChAdOx1/ChAdOx1 8 weeks apart, ChAdOx1/mRNA-1273 8 weeks apart, ChAdOx1/mRNA-1273 4 weeks apart, and mRNA-1273/mRNA-1273 4 weeks apart. The anti-SARS-CoV-2 spike IgG antibody titers on the day before booster vaccination and 4 weeks after booster vaccination were compared between participants with and without immunocompromising conditions. RESULTS: Among ChAdOx1-primed participants, a trend of lower anti-SARS-CoV-2 spike IgG titers before booster vaccination were found in participants with autoimmune diseases (geometric means, 34.76 vs. 84.25 binding antibody units [BAU]/mL, P = 0.173), compared to those without. Participants receiving immunosuppressants and/or immunomodulators had significant lower anti-SARS-CoV-2 spike IgG titers before booster vaccination than those without (geometric means, 36.39 vs. 83.84 BAU/mL; P = 0.001). Among mRNA-1273-boosted participants, anti-SARS-CoV-2 spike IgG titers 4 weeks after booster vaccination were similar across all the strata. Participants with autoimmune diseases and receiving immunosuppressants and/or immunomodulators, had numerically lower anti-SARS-CoV-2 spike IgG titers 4 weeks after booster vaccination compared to those without (geometric means, 1474.34 vs. 1923.23 and 1590.61 vs. 1918.38 BAU/mL; P > 0.05). CONCLUSION: The immunogenicity of prime vaccination with ChAdOx1 decreased by immune dysfunction, but enhanced after receiving boost vaccination with mRNA-1273. Our study results support the efficacy of mRNA-1273 booster dose among immunocompromised hosts.

Completion and Adverse Drug Events of Latent Tuberculosis Infection Treatment in Patients Receiving Dialysis: Predictors and Impacts of Different Regimens in a Prospective Cohort Study.

Although patients with end-stage renal disease receiving maintenance hemodialysis are at high risk for tuberculosis, the optimal treatment regimen for latent tuberculosis infection (LTBI) in this group has scarcely been studied for predictors of completion rate and adverse drug events (ADE). We prospectively enrolled dialysis patients for LTBI intervention from three medical centers in Taiwan. LTBI treatments were 3 months of weekly rifapentine plus isoniazid (3HP) and 9 months of daily isoniazid (9H). Completion rate, ADE, and reasons for treatment termination were recorded. Factors associated with treatment termination and ADE were analyzed using multivariate logistic regression. In all, 91 treatment courses (41 9H and 50 3HP) were surveyed. The completion rates were 61% for 9H and 82% for 3HP (P = 0.046). Use of 9H and development of ADE with a grade of ≥2 (≥grade 2 ADE) were associated with treatment termination. Hypersensitivity occurred in 29.2% of subjects in the 3HP group and 10.8% in the 9H group (P = 0.035) and independently correlated with 3HP regimen, diabetes mellitus (DM), and peritoneal dialysis (PD). Similarly, the independent predictors of ≥grade 2 ADE were use of 3HP regimen, presence of DM, and use of PD, whereas ≥grade 3 ADE were associated with eosinophil counts of >700/mm3 after 2 weeks of LTBI treatment even after adjustment for age and gender. In conclusion, for patients on dialysis, 3HP showed a higher rate of completion but also a higher rate of ≥grade 2 ADE than 9H. In addition, DM and PD were risk factors for ≥grade 2 ADE. Eosinophilia after 2-week treatment might be an alert for severe ADE.

Prevalence and impact of bladder and bowel disorders in women with breast cancer: A systematic review with meta-analysis.

BACKGROUND: One of the consequences of breast cancer treatments may be the onset of new, or aggravation of preexisting bladder and bowel disorders. However, the presence and impact of these disorders in women with breast cancer are poorly documented. The aim of this systematic review was to assess the prevalence, incidence and impact of bladder and bowel disorders in women undergoing breast cancer treatment. METHODS: A systematic search of six databases was conducted. Pooled prevalence rates and impact of bladder and bowel disorders were calculated using random-effects models. RESULTS: A total of 32 studies met the inclusion criteria, and 17 studies were included in the meta-analyses. The pooled estimate of women who experienced bladder disorders following sensitivity analysis, which removed one study reporting a result that deviated from the pooled estimate, was 38% (95% confidence interval [CI]: 32%-44%; I2 = 98%; n = 4584). The impact of bladder and bowel disorders on women's daily lives was relatively low (bladder [scale: 0-4]: mean: 0.8; 95% CI: 0.4-1.1; I2 = 99%; n = 4908; bowel [scale: 0-100]: mean 14.2; 95% CI: 9.4-19; I2 = 95%; n = 1024). CONCLUSION: This is the first study to comprehensively document the magnitude of bladder and bowel disorders in the breast cancer population. This meta-analysis found that women with breast cancer had a higher prevalence of urinary incontinence (38%) compared to women without breast cancer (21%). Given the extent and impact of our findings, screening and management of bladder and bowel disorders may be indicated in women with breast cancer to improve their health-related quality of life.

High prevalence of sexually transmitted coinfections among at-risk people living with HIV.

BACKGROUND/PURPOSE: Concurrent sexually transmitted infections (STIs) are not uncommon in at-risk populations, for which control requires integrated testing, treatment and prevention. METHODS: From May, 2019 to February, 2020, multiplex real-time PCR assays were prospectively performed to detect Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) in the urine and rectal/vaginal swab specimens collected from HIV-positive patients with a history of STIs or symptoms suggestive of STIs. Patients confirmed to have acquired STIs were treated according to treatment guidelines. RESULTS: During the study period, 430 participants (99.1% men who have sex with men and median age 37 years) were included. The overall prevalence of CT, NG, and/or TV infection was 30.0%, including 24.7%, 12.1%, and 0.2% for CT, NG, and TV infection, respectively. The factors associated with CT, NG, and/or TV infection were hepatitis B surface antigen (HBsAg) seropositivity (AOR, 2.76; 95% CI, 1.22-6.26), recently acquired hepatitis C virus (HCV) infection (AOR, 5.62; 95% CI, 1.99-15.88), using mobile dating application (AOR, 2.08; 95% CI, 1.13-3.83), and oral sex (AOR, 2.12; 95% CI, 1.04-4.32). The rates of CT, NG, and/or TV infection were 50.0% in participants with recent HCV infection, 44.2% in those with HBsAg positivity, and 35.9% in those with incident syphilis. Among participants completing test-of-cure visits, the microbiological cure rate was 91.7% and 90.0% for chlamydia and gonorrhea, respectively. CONCLUSION: HIV-positive participants had a high prevalence of CT and/or NG, especially those coinfected with viral hepatitis and syphilis. Our results strongly support integrated STI services in the population.

Effect of a Hepatitis A Vaccination Campaign During a Hepatitis A Outbreak in Taiwan, 2015-2017: A Modeling Study.

BACKGROUND: Beginning from 2015-2016, unprecedented large outbreaks of acute hepatitis A that predominantly affected men who have sex with men (MSM) reemerged across the continents. We assessed the impact of an early initiated hepatitis A virus (HAV) vaccination campaign that targeted MSM living with human immunodeficiency virus (HIV) during the 2015-2017 hepatitis A outbreak in Taiwan. METHODS: First, we ascertained the effectiveness of HAV vaccination for MSM living with HIV using a nested case-control study of 1470 persons living with HIV who were initially HAV-seronegative. We then fitted a model of HAV transmission among MSM, risk-structured by HIV status, to the actual epidemic curve of reported acute hepatitis A cases in Taiwan during 2015-2017. RESULTS: Fifty-five cases of acute hepatitis A were matched to 220 controls. Single-dose and 2-dose HAV vaccination provided protection rates of 96.1% and 97.8% among recipient MSM living with HIV, respectively. Model fitting yielded basic reproductive number estimates of 7.26 (MSM living with HIV) and 3.04 (MSM not living with HIV). In a counterfactual scenario without an HAV vaccination campaign, the outbreak would have involved 7153 hepatitis A cases during 2015-2017 in contrast to the 1352 that were observed. We therefore estimated that the HAV vaccination campaign averted 80.7% (sensitivity analysis, 48.8%-92.7%) of acute hepatitis A cases that would otherwise have occurred by the end of 2017. CONCLUSIONS: The early initiated HAV vaccination campaign, which targeted MSM living with HIV, very effectively curtailed the 2015-2017 hepatitis A outbreak in Taiwan.
