Macrolide-Resistant Mycoplasma pneumoniae Infections in Pediatric Community-Acquired Pneumonia.

A high prevalence rate of macrolide-resistant Mycoplasma pneumoniae (MRMP) has been reported in Asia. We performed a systematic review and meta-analysis to investigate the effect of macrolide resistance on the manifestations and clinical judgment during M. pneumoniae infections. We found no difference in clinical severity between MRMP and macrolide-sensitive Mycoplasma pneumoniae (MSMP) infections. However, in the pooled data, patients infected with MRMP had a longer febrile period (1.71 days), length of hospital stay (1.61 day), antibiotic drug courses (2.93 days), and defervescence time after macrolide treatment (2.04 days) compared with patients infected with MSMP. The risk of fever lasting for >48 hours after macrolide treatment was also significantly increased (OR 21.24), and an increased proportion of patients was changed to second-line treatment (OR 4.42). Our findings indicate diagnostic and therapeutic challenges after the emergence of MRMP. More precise diagnostic tools and clearly defined treatment should be appraised in the future.

Occupational evaluation of community-based psychiatric rehabilitation outcomes in individuals with severe mental illnesses: A ten-year retrospective study.

BACKGROUND: There is a lack of research on the effect of community-based psychiatric rehabilitation programs (CBPRs) in individuals with severe mental illness. This research used data from a retrospective study to examine the effect of a CBPR in a community rehabilitation center. MATERIALS AND METHODS: Clinical outcomes measures from a retrospective study were collected. Outcome measures were the Allen Cognitive Level Screen assessment, Purdue Pegboard Test, Chu's Attention Test, and Activities of Daily Living Rating Scale-III (ADLRS-III) before and immediately after 12 months of intervention. RESULTS: The 141 participants with mental illness were an average age of 35.29 years (SD = 8.75). The retrospective review of medical records showed 46 people dropped out within 12 months, and 95 people continued to participate in the rehabilitation program for 1 year. After 1 year of community rehabilitation, there was a trend for the participants who completed the intervention to improve on the ADLRS-III, Purdue Pegboard Test, and Chu's Attention Test. Participants who performed better on the occupational assessment were more likely to transit to the employment status. CONCLUSION: This study found the benefits of CBPR in work-related intervention for people with mental illness. Occupational assessments are relevant for studying changes in functional outcomes in people with mental illness receiving community-based rehabilitation.

Antimicrobial Susceptibility of E. coli Isolates from Intra-Abdominal Infections in the Asia-Pacific Region: Trends in Ciprofloxacin, Ceftriaxone, Cefepime, and Piperacillin/Tazobactam Susceptibility.

Purpose: To investigate the antibiotic susceptibility of Escherichia coli isolates in patients diagnosed with intra-abdominal infections (IAIs) in the Asia-Pacific region. Patients and Methods: This study was conducted at 50 medical hospitals across 9 countries/regions as part of the Study for Monitoring Antimicrobial Resistance Trends (SMART) surveillance program from 2014 to 2018. Nonduplicate isolates of aerobic and facultative gram-negative bacilli were collected and processed for further antimicrobial susceptibility testing. Results: A total of 10,709 isolates were collected, with E. coli (n=4737, 44.2%) being the leading pathogen causing IAIs, followed by Klebsiella pneumoniae (n=2429, 22.7%) and Pseudomonas aeruginosa (n=931, 8.7%). Community-associated (CA) E. coli isolates generally exhibited higher susceptibility rates for most antibiotics than hospital-associated (HA) isolates. In countries/regions other than Hong Kong, South Korea, and Singapore, HA isolates displayed lower susceptibility rates for multiple classes (≥4) of antibiotics. Among the commonly used antibiotics in IAIs, the overall susceptibility rate for ciprofloxacin was low, with an average of 41.3%. Ceftriaxone susceptibility rates in all selected countries were below 80% starting in 2018, ranging from 23.3% to 75.8%. The cefepime susceptibility rates varied across regions, with consistently reduced susceptibility ranging from 45.5% to 57.8% in India, Thailand, and Vietnam. Piperacillin/tazobactam demonstrated effectiveness against E. coli isolates in almost all countries except India, with a downward trend observed in the Philippines and Taiwan. Carbapenems remained effective against more than 90% of E. coli isolates, except in India. Conclusion: Prudent use of fluoroquinolones and ceftriaxone is advised when treating both CA and HA IAIs in the Asia-Pacific region. The low susceptibility rate of cefepime in India, Thailand, and Vietnam needs careful consideration in its administration. Moreover, the increase in nonsusceptibility to piperacillin/tazobactam in the Philippines and Taiwan poses a potential risk that should be closely monitored.

Distribution of ß-lactamases and emergence of carbapenemases co-occurring Enterobacterales isolates with high-level antibiotic resistance identified from patients with intra-abdominal infection in the Asia-Pacific region, 2015-2018.

PURPOSE: In this study, we aimed to assess the geographic distribution and molecular characteristics of ß-lactamases among Enterobacterales isolates causing intra-abdominal infections (IAIs) from 2015 to 2018 in the Asia-Pacific region. METHOD: Isolates were investigated for extended-spectrum ß-lactamases (ESBLs), AmpC ß-lactamases, and carbapenemases using multiplex PCR assays and full-gene DNA sequencing. RESULT: A total of 832 Enterobacterales isolates from 8 different countries with ß-lactamase genes were analysed. Plasmid-mediated ESBLs and AmpC ß-lactamases were encoded in 598 (71.9 %) and 314 (37.7 %) isolates, respectively. In 710 (85.3 %) carbapenemase-negative isolates, positivity for both AmpC ß-lactamases and ESBLs was identified in 51 (8.5 %) Escherichia coli and 24 (3.4 %) Klebsiella pneumoniae isolates. The most prevalent countries were Taiwan and Vietnam, and the co-occurrence of CMY/CTX-M in E. coli and DHA-1/ESBLs in K. pneumoniae was predominant. All isolates showed high susceptibility to colistin, but susceptibility to carbapenems varied among different resistance mechanism combinations. Among 122 (14.7 %) isolates encoding carbapenemase, NDM (n = 67, including 64.2 % NDM-1) was the most common, followed by the OXA-48-type (n = 49), KPC (n = 24) and IMP (n = 4). The most prevalent country was Thailand (n = 44), followed by Vietnam (n = 35) and the Philippines (n = 21). Twenty-two isolates were found to encode multiple carbapenemases, 16 of which were collected from Thailand and harbored NDM-1, OXA-232 and CTX-M-15. Despite high susceptibility to amikacin, susceptibility to colistin was only 56 %. CONCLUSION: The emergence of carbapenem-non-susceptible AmpC/ESBL co-occurring Enterobacterales and colistin non-susceptible carbapenemases co-occurring K. pneumoniae highlights potential therapeutic challenges in the Asia-Pacific region.

Circulating pediatric respiratory pathogens in Taiwan during 2020: Dynamic change under low COVID-19 incidence.

BACKGROUND: In Taiwan, there were only 799 confirmed COVID-19 cases in 2020. The unique backdrop amidst a pandemic and promotion of nonpharmaceutical interventions generated some distinct changes in the epidemiology of common respiratory pathogens. In this study, we aimed to investigate the dynamic changes in respiratory pathogens in children during 2020. METHODS: We performed a retrospective cohort study at a tertiary hospital in southern Taiwan during 2020. Patients aged 0-18 years who visited the pediatric emergency department were enrolled. Children who presented with clinical symptoms (fever or respiratory illness) and received nasopharyngeal swabs for multiplex polymerase chain reaction (PCR) were included in our analysis. We also compared respiratory syncytial virus (RSV) trends from previous years by PCR and lateral flow immunochromatographic assays from 2017 to 2020. RESULTS: A total of 120 children were tested. The overall detection rate was 55%. With strengthened restrictions, the detection rate dropped from 70% to 30%. However, non-enveloped viruses (rhinovirus/enterovirus and adenovirus) were in constant circulation. Upon easing prevention measures, the detection rate remained above 60%, and an outbreak of an enveloped virus (RSV and parainfluenza virus) was noted. Compared with 2017-2019, the cyclical RSV epidemic was delayed, with a large surge in late 2020. CONCLUSIONS: We observed a constant circulation of non-enveloped viruses when strict nonpharmaceutical interventions were employed and a delayed surge of enveloped viruses during the easing of restrictions. Continuous surveillance and monitoring of the evolutionary dynamics of respiratory viruses is important, while easing restrictions requires balanced judgment.

Weight Gain Associated with COVID-19 Lockdown in Children and Adolescents: A Systematic Review and Meta-Analysis.

BACKGROUND: Lockdown is an effective nonpharmaceutical intervention to reduce coronavirus disease 2019 (COVID-19) transmission, but it restricts daily activity. We aimed to investigate the impact of lockdown on pediatric body weight and body mass index (BMI). METHODS: The systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. Four online databases (EMBASE, Medline, the Cochrane Library and CINAHL) were searched. RESULTS: The pooled results showed that lockdown was associated with significant body weight gain (MD 2.67, 95% CI 2.12-3.23; p < 0.00001). The BMI of children with comorbidities or obesity did not change significantly. The BMI of general population was significantly higher during lockdown than before the pandemic (MD 0.94, 95% CI 0.32-1.56; p = 0.003). However, heterogeneity was high (I2 = 84%). Among changes in weight classification, increases in the rates of obesity (OR 1.23, 95% CI 1.10-1.37; p = 0.0002) and overweight (OR 1.17, 95% CI 1.06-1.29; p = 0.001) were reported. CONCLUSIONS: Our meta-analysis showed significant increases in body weight and BMI during lockdown among school-age children and adolescents. The prevalence of obesity and overweight also increased. The COVID-19 pandemic worsened the burden of childhood obesity.

Severe Mycoplasma pneumoniae infections with prolonged fever in a child: Delayed treatment is as important as macrolide resistance.

We report a 7-year-old girl who got Mycoplasma pneumoniae infection with prolonged fever. Macrolide was used on day 14 of illness but fever persisted with progressive lung consolidation. Oral prednisolone was administered on day 33 then fever subsided with dramatically clinical improvement (decreased CRP and resolution of lung consolidation). In this case, delayed effective antibiotic treatment with inflammation may be the major factor contributing to the fever rather than ongoing infection.

Association of visual motor processing and social cognition in schizophrenia.

Patients with schizophrenia have difficulties in social cognitive domains including emotion recognition and mentalization, and in sensorimotor processing and learning. The relationship between social cognitive deficits and sensorimotor function in patients with schizophrenia remains largely unexplored. With the hypothesis that impaired visual motor processing may decelerate information processing and subsequently affects various domains of social cognition, we examined the association of nonverbal emotion recognition, mentalization, and visual motor processing in schizophrenia. The study examined mentalization using the verbal subset of the Chinese version of Theory of Mind (CToM) Task, an equivalent task of the Faux Pas Test; emotion recognition using the Diagnostic Analysis of Nonverbal Accuracy 2-Taiwan version (DANVA-2-TW), and visual motor processing using a joystick tracking task controlled for basic motor function in 34 individuals with chronic schizophrenia in the community and 42 healthy controls. Patients with schizophrenia had significantly worse performance than healthy controls in social cognition, including facial, prosodic emotion recognition, and mentalization. Visual motor processing was also significantly worse in patients with schizophrenia. Only in patients with schizophrenia, both emotion recognition (mainly in prosodic modality, happy, and sad emotions) and mentalization were positively associated with their learning capacity of visual motor processing. These findings suggest a prospective role of sensorimotor function in their social cognitive deficits. Despite that the underlying neural mechanism needs further research, our findings may provide a new direction for restoration of social cognitive function in schizophrenia by enhancing visual motor processing ability.

Streptococcus gallolyticus - A potentially neglected pathogen causing neonatal sepsis not covered by routine group B streptococcus screening.

We report 4 cases of neonatal sepsis caused by Streptococcus gallolyticus. The clinical course was quite similar to early-and late-onset group B streptococcus disease. None of the mothers had group B streptococcus (GBS) colonization on prenatal screening nor received intrapartum antibiotics. We proposed the sporadic distribution of S. gallolyticus sepsis among neonates was partly due to relatively low colonization rate in adults compared with GBS. Species determination of S. gallolyticus may not be available using conventional microbiological methods and may contribute to underestimation or misclassification. In our series, we highlighted the importance of S. gallolyticus as an important pathogen in neonatal sepsis deserving further surveillance.

Increased age and proton pump inhibitors are associated with severe Clostridium difficile infections in children.

BACKGROUND: Clostridium difficile infection (CDI) is increasing in children. We aimed to compare the clinical characteristics between CDI and colonization and to identify the risk factors for severe diseases of CDI in children. METHOD: We retrospectively reviewed 124 children (1-18 years old) from 2011 to 2018. CDI was defined as diarrhea (≥3 loose stool in the past 24 h) with confirmed toxigenic strain. Colonization was defined as presence of C. difficile without clinical symptoms. Severe diseases included ileus, acute kidney injury, gastrointestinal bleeding or mortality. Patients younger than 1 year old and coinfections with other enteric pathogens were excluded. RESULTS: Among 124 patients with C. difficile identified, 49 of them fulfilled CDI definition and 75 had C. difficile colonization. Children with CDI were more likely to present with watery (74% vs. 1%, p < 0.01) and mucoid stool (25% vs. 7%, p < 0.01) and occult blood in stool (67% vs. 33%, p < 0.01) than children with colonization. In CDI cases, elevated age-adjusted creatinine (18% vs. 0%, p = 0.03) and hyponatremia (134 mEq/L vs. 137 mEq/L, p = 0.04) were found. Also, they had more complicated diseases (27% vs. 0%, p < 0.01). On multivariate analysis, age older than 4 years (adjusted odds ratio: 5.83; 95% confidence interval: 1.05-32.27) and proton pump inhibitor use (PPI) (adjusted odds ratio: 7.25; 95% confidence interval: 1.07-49.07) were the independent factors for severe diseases. CONCLUSIONS: Watery diarrhea, mucoid stool and occult blood in stool could differentiate CDI from colonization. Patients with increased age and previous PPI use were the independent risk factors for severe diseases in children.

Clinical risk stratification of children with SIOPEL high-risk hepatoblastoma in Taiwan.

BACKGORUND: Hepatoblastoma is the most common primary liver malignancy in young children. METHODS: To identify predictors of the clinical outcomes of hepatoblastoma, we retrospectively reviewed the medical records of 45 children with hepatoblastoma in the National Taiwan University Hospital from 1998 to 2018. All of the children were classified as high risk according to the pretreatment extent of disease (PRETEXT) staging system. The patients' clinical data (sex, age at diagnosis, PRETEXT status, presence of metastasis or tumor rupture, tumor pathologic type, and clinical outcomes) were analyzed. RESULTS: A total of 45 children with high-risk hepatoblastoma were diagnosed at an average age of 3.2 years. The survival analysis showed that the event-free survival duration was significantly longer in patients aged ≤1.25 years at diagnosis than those >1.25 years (hazard ratio = 2.86, p = 0.036). The absence of initial tumor rupture was associated with longer event-free survival (hazard ratio = 2.74, p = 0.039). Diagnosis at age >1.25 years was correlated with the presence of multifocal liver tumors (p = 0.0002) and tumor rupture at diagnosis (p = 0.02). There was no significant difference in event-free survival between the groups classified as intermediate versus high risk according to the Children's Hepatic tumors International Collaboration hepatoblastoma stratification system (p = 0.13). CONCLUSIONS: Diagnosis at ≤ 1.25 years of age and absence of initial tumor rupture were predictive of a good clinical prognosis in Taiwanese children with hepatoblastoma.

Case report: painful exanthems caused by enterovirus D68 in an adolescent.

RATIONALE: Unlike other enteroviruses which can cause herpangina or hand-foot-and-mouth disease, enterovirus D68 (EV-D68) has usually been linked to respiratory and neurological problems in young children. Skin manifestations had rarely been described in current literatures. PATIENT CONCERNS: We report a 17-year-old girl with fever and painful skin rash over legs and soles for 9 days. Pitting edema was also noted below the knees. There was no respiratory tract or neurological symptoms in this patient. DIAGNOSES: EV-D68 was detected from a throat swab by RT-PCR and confirmed to be subclade B3 by sequencing. INTERVENTIONS: Supportive management. OUTCOMES: The patient was afebrile after 9 days and got full recovery on the 23rd day at outpatient follow-up. LESSONS: To the best of our knowledge, this is the first report of EV-D68 infection with skin manifestations, clinical images, and detailed clinical course. Our findings in this particular case extend the understanding of the disease spectrum.
