RESUMO
BACKGROUND: Hospital-based occupational health (HBOH) is uniquely positioned to not only prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission, but to care for healthcare workers (HCWs) sick with coronavirus disease 2019 (COVID-19). AIMS: The primary objective of this study is to describe a system where HBOH services were adapted to provide a monitoring programme whereby HCWs with SARS-CoV-2 received daily evaluations and treatment options in order to improve access to care, and to report the clinical outcomes and predictors of hospitalization in HCWs enrolled in the programme. A secondary objective is to compare clinical outcomes to data on national HCWs with COVID-19. METHODS: This retrospective cohort study used survey data collected on HCWs at a university health system with COVID-19 from 1 March 2020 through 1 December 2021. A firth regression model was used to examine the unadjusted and adjusted association between clinical factors and hospitalization. RESULTS: The study cohort included 4814 HCWs with COVID-19. Overall hospitalizations were 119 (2%), and there were six deaths (0.12%). Predictors of hospitalization include several co-morbidities and symptoms. A total of 1835 HCWs monitored before vaccine or monoclonal antibody availability were compared with data on U.S. HCWs in a similar time period. The monitored HCWs had a lower rate of co-morbidities (19% versus 44%, Pâ <â 0.001), a lower hospitalization rate (3% versus 8% Pâ <â 0.001) and case-fatality rate (0.11% versus 0.95% Pâ <â 0.001). CONCLUSIONS: This monitoring strategy for COVID-19 may be feasible for HBOH systems to implement and improve access to care, but more data are needed to determine if it improves outcomes.

PURPOSE: The short-term outcomes of robotic right hemicolectomy for right colon cancer have been extensively studied in comparison to conventional laparoscopic right hemicolectomy. However, the long-term oncological outcomes of the two approaches have not been investigated, except in single-center retrospective studies. Therefore, this meta-analysis aimed to investigate the long-term oncological outcomes of robotic right hemicolectomy compared with those of laparoscopic right hemicolectomy for right colon cancer. METHODS: We searched PubMed, EMBASE, and Cochrane Library for studies comparing robotic right hemicolectomy with conventional laparoscopic right hemicolectomy for right colon cancer from the date of database inception to August 2022. For survival data extraction, hazard ratios (HRs) with 95% confidence intervals (CI) were calculated using random- or fixed-effects models from the Kaplan-Meier survival curves in the included studies. All calculations and statistical tests were performed using Review Manager software, version 5.4. RESULTS: A total of 523 patients (robotic right hemicolectomy, 230; laparoscopic right hemicolectomy, 293) from five studies were included in this meta-analysis. There were no significant differences in patient characteristics between the two groups. In terms of pathological characteristics, TNM stage was not different and revealed no differences in the number of harvested lymph nodes even though a larger number of lymph nodes were harvested in the robotic group in one study. Pooled analyses demonstrated no significant difference in disease-free survival (HR 0.72, 95% CI 0.46-1.13, p = 0.15) and overall survival (HR 0.73, 95% CI 0.48-1.13, p = 0.16) between robotic and laparoscopic right hemicolectomy for right colon cancer. CONCLUSION: Robotic right hemicolectomy for right colon cancer is comparable with conventional laparoscopic right hemicolectomy in terms of long-term oncological survival. More prospective, multicenter, randomized trials are necessary to determine the oncologic safety of robotic right hemicolectomy.

PURPOSE: The da Vinci SP® (dVSP) surgical system (Intuitive Surgical, Sunnyvale, CA, USA), a robotic platform designed for single-incision surgery, overcame the need for multiple ports in traditional robotic surgery and issues including triangulation and retraction in single-incision laparoscopic surgery. However, previous studies only included case reports or series with small sample sizes. The aim of this study was to assess the safety and performance of the dVSP surgical system and its instruments and accessories for colorectal procedures. METHODS: The medical records of patients who had surgery with the dVSP from March 2019 to September 2021 at Ewha Womans University Seoul Hospital were investigated. The pathologic and follow-up data of patients who had malignant tumors were analyzed separately to evaluate oncological safety. RESULTS: Fifty patients (26 male and 24 female) with a median age of 59 years (interquartile range 52.5-63.0 years) were enrolled. The procedures included low anterior resection with total mesorectal excision (n = 16), sigmoid colectomy with complete mesocolic excision and central vessel ligation (CME + CVL) (n = 14), right colectomy with CME + CVL (n = 9), left colectomy with CME + CVL (n = 4), right colectomy (n = 6), and sigmoid colectomy (n = 1). Operative time significantly decreased after 25 cases (early phase vs. late phase; operative time 295.0 min vs. 250.0 min, p = 0.015; docking time 16.0 min vs. 12.0 min, p = 0.001; console time 212.0 min vs. 190.0 min, p = 0.019). Planned procedures were successfully completed in all patients. Postoperative outcomes were acceptable with only six cases of mild adverse events through a 3-month follow-up. No local recurrence and only one case of systemic recurrence occurred within 1 year postoperatively. CONCLUSIONS: This study demonstrated the surgical and oncological safety and feasibility of dVSP, which may be a novel surgical platform for colorectal surgery.

Sarcoidosis is a multi-systemic, non-caseating granulomatous disorder with an idiopathic aetiology. We report a 58-year-old Malay woman, with underlying type II diabetes mellitus, hypertension and history of stage II pulmonary sarcoidosis presenting with incidental finding of multiple hypodense liver lesions. Her recent contrasted enhanced computed tomography of the abdomen and pelvis demonstrated multiple intra-abdominal lymphadenopathies with evidence of liver and splenic infiltrations. Her ageappropriate malignancy screening was negative while liver biopsy showed non-caseating granulomatous hepatitis consistent with hepatic sarcoidosis. In view of her normal liver enzymes and normalised serum calcium levels, no immunosuppressive therapy was commenced. She remains asymptomatic and is currently under our close monitoring.

Slackia exigua (S. exigua) is an obligatory anaerobic coccobacillus under the family of Coriobacteriaceae. It is a rare cause of pyogenic extraoral infections. We report a 58-year-old lady with good past health presented with fulminant community-acquired pneumonia causing acute respiratory distress syndrome caused by S. exigua requiring veno-venous extra-corporeal membrane oxygenation (VV-ECMO). Bacterial identification can be challenging and often require 16 S rRNA and MALDI-TOF MS. The patient was treated with amoxicillin-clavulanic acid according to sensitivity and made significant recovery.

Cat scratch disease is caused by Bartonella henselae and usually manifests as localized lymphadenopathy and fever in immunocompetent patients. Immunocompromised patients are at risk for developing disseminated disease affecting the liver, spleen, eyes, central nervous system, and other organs. Bartonellosis is infrequently reported in solid organ transplant recipients, and published case reports usually discuss disseminated infection. Localized ocular disease with B. henselae, while well documented in immunocompetent hosts, is uncommon in immunocompromised patients. Herein, we present 2 cases of ocular bartonellosis in renal transplant patients, 1 with disseminated infection, and 1 without.

The test performance and potential clinical utility of the ePlex blood culture identification Gram-negative (BCID-GN) panel was evaluated relative to matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry on bacterial isolates and conventional antimicrobial susceptibility testing. The majority (106/108, 98.1%) of GN bacteria identified by MALDI were on the BCID-GN panel, and valid tests (107/108, 99.1%) yielded results on average 26.7 h earlier. For all valid tests with on-panel organisms, the positive percent agreement was 102/105 (97.2%) with 3 false negatives and the negative percent agreement was 105/105. Chart review (n = 98) showed that in conjunction with Gram stain results, negative pan-Gram-positive (GP) markers provided the opportunity to discontinue GP antibiotic coverage in 63/98 (64.3%) cases on average 26.2 h earlier. Only 8/12 (66.7%) Enterobacterales isolates with resistance to third-generation cephalosporins harbored the CTX-M gene. In contrast, 8/8 CTX-M+ samples yielded a resistant isolate. Detection of 1 Stenotrophomonas maltophilia (18 h), 1 OXA23/48+ Acinetobacter baumannii (52.4 h), and 3 CTX-M+ Enterobacterales isolates on ineffective treatment (47.1 h) and 1 on suboptimal therapy (72.6 h) would have additionally enabled early antimicrobial optimization in 6/98 (6.1%) patients. IMPORTANCE The GenMark Dx ePlex rapid blood culture diagnostic system enables earlier time to identification of antimicrobial-resistant Gram-negative bacteria causing bloodstream infections. Its ability to rule out Gram-positive bacteria enabled early discontinuation of unnecessary antibiotics in 63/98 (64.3%) cases on average 26.2 h earlier. Detection of bacteria harboring the CTX-M gene as well as early identification of highly resistant bacteria such as Stenotrophomonas maltophilia and Acinetobacter baumannii enabled optimization of ineffective therapy in 6/98 (6.1%) patients. Its implementation in clinical microbiology laboratories optimizes therapy and improves patient care.

BACKGROUND: Modern video laryngoscopes (VLSs) provide a superior view of the glottis, facilitating easier intubations. This study evaluates the forces applied to the maxillary incisors when using various VLSs and a Macintosh blade. METHODS: Fifty consecutive surgery patients were randomly assigned to receive laryngoscopy from a pair of four blades investigated in the study - the VLS GlideScope(®) (Verathon Inc., Bothell, WA, USA), V-Mac™ Storz(®) (Karl Storz, Tuttlingen, Germany), and McGrath™ (Aircraft Medical, Edinburgh, United Kingdom); and the classic Macintosh blade also from Storz(®) (Karl Storz). An endotracheal tube (ETT) was brought into position anterior to the vocal cords, with actual intubation carried out only with the second of the laryngoscopes. Sensors measured the forces directly applied to the patient's maxillary incisors while inserting the ETT. Other common metrics of intubation difficulty (e.g. Mallampati grade, Cormack-Lehane grade, and time) were also recorded. RESULTS: Only one patient was not intubated within the standard study parameters and was converted to the hospital protocols for difficult intubations. The forces applied to the maxillary incisors were significantly greater with the Macintosh blade compared with all VLSs. There were no differences between the VLSs with regard to the forces. Patient characteristics, including Mallampati grade, were not predictive of the forces applied. CONCLUSIONS: All VLSs considered were safer for the patient than was the Macintosh blade in terms of the forces applied to the maxillary teeth, time, number of insertion attempts, and view achieved of the glottic arch. There is a small, but significant, difference in the time and number of insertion attempts required during laryngoscopy with the different VLSs. There was no difference in the forces applied. The geometry of the respective blades may be an important component in the ease of laryngoscopy.

The test performance and potential clinical utility of the ePlex® BCID Gram-Positive (GP) Panel was evaluated relative to MALDI-TOF mass spectrometry on bacterial isolates and traditional antimicrobial susceptibility testing. All GP bacteria (n = 100) in the study were represented on the panel including 50 common skin contaminants, and 7/7 coinfections. The positive percent agreement (PPA) was 97/97 with 2 false positives. Detection of vanA yielded a PPA of 4/4 and NPA of 9/9. mecA gene detection exhibited a PPA of 14/14 and NPA of 14/14 for S. aureus and a PPA of 31/32(97%) and NPA of 16/16 for CNS with 1 false negative. Chart reviews (n = 80) identified a mean 24.4h faster time to organism identification, 53.4h earlier optimization in 15(18.8%) patients based on AMR gene detection, 29.2h earlier optimization for 8(10%) patients infected with organisms, such as streptococci, with very low resistance rates, and 42.9h earlier discontinuation of antimicrobials for 14(17.5%) patients with contaminant cultures.

Primary care providers should be alert to travel-related infections. Around 10-40% of returning travelers from all destinations and 15-70% of travelers from tropical settings experience ill health, either overseas or upon returning home.1 A systematic approach concentrating on possible infections should be undertaken based on the patient's travel location, immunization history, presence of malaria chemoprophylaxis at the destination, other potential exposures, incubation period, and clinical presentation.2-3 The World Health Organization (WHO) website is constantly being updated on specific travel-related infections and recent geographical outbreaks. In this paper, we report a case of severe falciparum malaria in a returned traveler.
RESUMO

Nosocomial outbreaks of infectious diseases in psychiatric facilities are not uncommon but the implementation of infection control measures is often difficult. Here, we report an outbreak of an acute respiratory illness in a psychiatric ward between 29 July and 20 August 2005 involving 31 patients. Human metapneumovirus was detected in seven (23%) patients by reverse transcription-polymerase chain reaction and nucleotide sequencing. A review of outbreak surveillance records showed that six nosocomial outbreaks occurred in the year 2005, of which four (67%) were confirmed or presumably related to a respiratory viral infection. Directly observed deliveries of alcohol hand rub 4-hourly during daytime to all psychiatric patients was instituted in December 2005. Only one nosocomial respiratory viral outbreak occurred in the following year. The total number of patients and staff involved in nosocomial outbreaks due to presumed or proven respiratory virus infections decreased significantly from 60 to six (P<0.001), whereas those due to all types of nosocomial outbreaks also decreased from 70 to 24 (P=0.004). Alcohol hand rub has been shown to have potent bactericidal and virucidal activity against a wide range of nosocomial pathogens. Regular use of directly observed alcohol hand rub may decrease the incidence and scale of nosocomial outbreaks due to enveloped respiratory viruses especially in mentally incapacitated patients.

Hormonal changes may be important in the onset and clearance of bacterial vaginosis. We studied vaginal flora and serum oestradiol levels of 55 women at baseline and during hormonal treatment. None developed bacterial vaginosis (BV) from normal vaginal flora, 69% of women had normal flora at baseline increasing to 91% following hormonal treatment. The mean oestradiol level with BV was 39.07 ng/L compared with 176.41 ng/L with normal flora. Non-smokers had a mean oestradiol level of 173.95 ng/L compared with 118.67 ng/L in smokers. Recombinant follicle-stimulating hormone resulted in a mean oestradiol rise of 113.9 ng/L. The mean rise was 330.4 ng/L with improved vaginal flora but only 15.1 ng/L in persistently abnormal or worsening flora. A rise in oestradiol in this group of women was associated with a significant reduction of abnormal flora. Reversion from BV to normal flora was associated with a greater rise in oestradiol than where abnormal flora persisted or worsened. This study supports a possible hormonal influence in the natural history of BV. The lower oestradiol levels in smokers may help explain their increased risk of BV.

BACKGROUND AND OBJECTIVES: Anesthesiologists are reluctant to consider higher levels for spinal anesthesia, largely due to direct threats to the spinal cord. The goal of this study is to investigate, with magnetic resonance imaging (MRI), the distances between the relevant structures of the spinal canal (spinal cord, thecal tissue, etc.) to determine modal anatomical positions for neuraxial anesthesia. METHOD: A group of 19 patients were imaged with an MRI scanner in supine position. Medial sagittal slices of the thoracic and lumbar spine were measured for the relative distances between anatomical structures, including epidural space, dura, and spinal cord. RESULTS: The posterior dura - spinal cord distance is significantly greater in the middle thoracic region than at upper and lower thoracic levels (e.g. T6 9.5 +/- 1.8 mm, T12 3.7 +/- 1.2 mm, p < 0.001, T1 4.7 +/- 1.7 mm, p < 0.001). There is variation in modal distances between the structures important for neuraxial anesthesia, at different levels of the spinal canal. CONCLUSIONS: The spinal cord tends to follow the straightest line through the imposed geometry of the spine. Considering the necessary angle of entry of the needle at mid-thoracic levels, there is relatively (more than at upper thoracic and lumbar levels) substantial separation of cord and surrounding thecal tissue. Anesthesiologists perform spinal blockades up to the L2-L3 interspace, but avoid higher levels for fear of neurological damage. The information that there is substantially more space in the dorsal subarachnoid space at thoracic level, might lead to potential applications in regional anesthesia. In contrast, the cauda equina sits more dorsally in the lumbar region.

BACKGROUND: Klebsiella pneumoniae (KP) infection is associated with high morbidity and mortality. Multidrug resistance, especially extended-spectrum ß-lactamase (ESBL) production, in KP is endemic worldwide. AIM: To evaluate the clinical characteristics and outcomes of patients with KP bacteraemia in critical care and general ward settings. METHODS: Adult patients admitted to a regional hospital in Hong Kong from January 1st, 2009 to June 30th, 2016 (7.5 years) with KP bacteraemia were included. Demographics, clinical features, microbiological characteristics, and outcomes were analysed. FINDINGS: Among 853 patients, 178 (20.9%) required critical care and 176 (20.6%) died within 30 days of hospital admission. Thirty-day survivors were younger (P<0.001), had milder disease (defined by Sequential Organ Failure Assessment score) (P<0.001), presented with hepatobiliary sepsis (P<0.001) or urosepsis (P<0.001), less septic shock (P=0.013), fewer invasive organ supports (P<0.001), and had appropriate empirical antibiotics (P<0.001). Cox regression analysis showed that respiratory tract infection (hazard ratio: 2.99; 95% confidence interval: 2.061-4.337; P≤0.001), gastrointestinal tract infection (excluding hepatobiliary system) (2.763; 1.761-4.337; P≤0.001), mechanical ventilation (2.202; 1.506-3.221; P≤0.001), medical case (1.830; 1.253-2.672; P=0.002), inappropriate empirical antibiotics (1.716; 1.267-2.324; P≤0.001), female (1.699; 1.251-2.307; P<0.001), age >65 years (1.692; 1.160-2.467; P=0.006), and presence of solid tumour (1.457; 1.056-2.009; P=0.022) were independent risk factors for 30-day mortality. Unexpectedly, diabetes mellitus was associated with better 30-day survival (P=0.002). A total of 102 patients (12.0%) had infections with ESBL-producing strains, which were not associated with higher 30-day mortality. CONCLUSION: KP bacteraemia is associated with high 30-day mortality. Site of infection, patients' comorbidities and appropriate use of empirical antibiotic are important predictors of patients' outcomes.

Bacterial vaginosis (BV) frequently recurs after treatment. One option in the management of recurrences is to keep the vaginal pH at 4.5 or less, in order to prevent overgrowth of bacteria, until the normal lactobacilli are re-established. We report the outcome of using maintenance acetic acid vaginal gel, after treatment of BV, in a sample of 49 women with frequent recurrences. Half of the women had no further recurrences, and in those who did there was a significant increase in time to first recurrence (4.8 months) after commencing the gel compared with the previous recurrence (2.1 months). Prior to using acidic gel, the mean recurrence rate in 49 women was 4.4 per woman/year, and this was reduced to 0.6 recurrences per woman/year. As there are few effective therapies for women with recurrent BV, we feel this offers an option that can currently be used in clinical practice.
