Our hospital replaced the format for delivering portable antimicrobial prescribing guidance from a paper-based pocket guide to a smartphone application (app). We used this opportunity to assess the relationship between its use and the attitudes and behaviours of antimicrobial prescribers. We used 2 structured cross-sectional questionnaires issued just prior to and 3 months following the launch of the smartphone app. Ordinal Likert scale responses to both frequencies of use and agreement statements permitted quantitative assessment of the relationship between variables. The smartphone app was used more frequently than the pocket guide it replaced (p < 0.01), and its increased use was associated with sentiments that the app was useful, easy to navigate and its content relevant. Users who used the app more frequently were more likely to agree that the app encouraged them to challenge inappropriate prescribing by their colleagues (p = 0.001) and were more aware of the importance of antimicrobial stewardship (p = 0.005). Reduced use of the app was associated with agreement that senior physicians' preferences for antimicrobial prescribing would irrespectively overrule guideline recommendations (p = 0.0002). Smartphone apps are an effective and acceptable format to deliver guidance on antimicrobial prescribing. Our findings suggest that they may empower users to challenge incorrect prescribing, breaking well-established behaviours, and thus supporting vital stewardship efforts in an era of increased antimicrobial resistance. Future work will need to focus on the direct impact on drug prescriptions as well as identifying barriers to implementing smartphone apps in other clinical settings.

Empyema is an increasingly frequent clinical problem worldwide, and has substantial morbidity and mortality. Our objectives were to identify the clinical, surgical and microbiological features, and management outcomes, of empyema. A retrospective observational study over 12 years (1999-2010) was carried out at The Heart Hospital, London, United Kingdom. Patients with empyema were identified by screening the hospital electronic 'Clinical Data Repository'. Demographics, clinical and microbiological characteristics, underlying risk factors, peri-operative blood tests, treatment and outcomes were identified. Univariable and multivariable statistical analyses were performed. Patients (n = 406) were predominantly male (74.1%); median age = 53 years (IQR = 37-69). Most empyema were community-acquired (87.4%) and right-sided (57.4%). Microbiological diagnosis was obtained in 229 (56.4%) patients, and included streptococci (16.3%), staphylococci (15.5%), gram-negative organisms (8.9%), anaerobes (5.7%), pseudomonads (4.4%) and mycobacteria (9.1%); 8.4% were polymicrobial. Most (68%) cases were managed by open thoracotomy and decortication. Video-assisted thoracoscopic surgery (VATS) reduced hospitalisation from 10 to seven days (P = 0.0005). All-cause complication rate was 25.1%, and 28 day mortality 5.7%. Predictors of early mortality included: older age (P = 0.006), major co-morbidity (P = 0.01), malnutrition (P = 0.001), elevated red cell distribution width (RDW, P<0.001) and serum alkaline phosphatase (P = 0.004), and reduced serum albumin (P = 0.01) and haemoglobin (P = 0.04). Empyema remains an important cause of morbidity and hospital admissions. Microbiological diagnosis was only achieved in just over 50% of cases, and tuberculosis is a notable causative organism. Treatment of empyema with VATS may reduce duration of hospital stay. Raised RDW appears to associate with early mortality.

Tuberculosis (TB) is the most common cause of death from infectious disease worldwide. A substantial proportion of patients presenting with extrapulmonary TB have urogenital TB (UG-TB), which can easily be overlooked owing to non-specific symptoms, chronic and cryptic protean clinical manifestations, and lack of clinician awareness of the possibility of TB. Delay in diagnosis results in disease progression, irreversible tissue and organ damage and chronic renal failure. UG-TB can manifest with acute or chronic inflammation of the urinary or genital tract, abdominal pain, abdominal mass, obstructive uropathy, infertility, menstrual irregularities and abnormal renal function tests. Advanced UG-TB can cause renal scarring, distortion of renal calyces and pelvic, ureteric strictures, stenosis, urinary outflow tract obstruction, hydroureter, hydronephrosis, renal failure and reduced bladder capacity. The specific diagnosis of UG-TB is achieved by culturing Mycobacterium tuberculosis from an appropriate clinical sample or by DNA identification. Imaging can aid in localizing site, extent and effect of the disease, obtaining tissue samples for diagnosis, planning medical or surgical management, and monitoring response to treatment. Drug-sensitive TB requires 6–9 months of WHO-recommended standard treatment regimens. Drug-resistant TB requires 12–24 months of therapy with toxic drugs with close monitoring. Surgical intervention as an adjunct to medical drug treatment is required in certain circumstances. Current challenges in UG-TB management include making an early diagnosis, raising clinical awareness, developing rapid and sensitive TB diagnostics tests, and improving treatment outcomes.

PurposeUndiagnosed urinary tract infections (UTIs) in pregnancy are associated with adverse perinatal outcome. Urine microbiology cultures reported as ‘mixed bacterial growth’ (MBG) frequently present a diagnostic dilemma for healthcare providers. We investigated external factors contributing to elevated rates of (MBG) within a large tertiary maternity centre in London, UK, and assessed the efficacy of health service interventions to mitigate these.DescriptionThis prospective, observational study of asymptomatic pregnant women attending their first prenatal clinic appointment aimed to establish (i) the prevalence of MBG in routine prenatal urine microbiology cultures, (ii) the association between urine cultures and the duration to laboratory processing and (iii) ways in which MBG may be reduced in pregnancy. Specifically we assessed the impact of patient-clinician interaction and that of an education package on optimal urine sampling technique.AssessmentAmong 212 women observed over 6 weeks, the negative, positive and MBG urine culture rates were 66%, 10% and 2% respectively. Shorter duration from urine sample collection to laboratory arrival correlated with higher rates of negative cultures. Urine samples arriving in the laboratory within 3 hours of collection were most likely to be reported as culture negative (74%), and were least likely to be reported as MBG (21%) or culture positive (6%), compared to samples arriving > 6 hours (71%, 14% and 14% respectively; P < 0.001). A midwifery education package effectively reduced rates of MBG (37% pre-intervention vs 19% post-intervention, RR 0.70, 95% CI 0.55 to 0.89). Women who did not receive verbal instructions prior to providing their sample had 5-fold higher rates of MBG (P < 0.001).ConclusionAs many as 24% of prenatal urine screening cultures are reported as MBG. Patient-midwife interaction before urine sample collection and rapid transfer of urine samples to the laboratory within 3 hours reduces the rate of MBG in prenatal urine cultures. Reinforcing this message through education may improve accuracy of test results.

Tuberculosis (TB) is one of the top ten causes of death worldwide. In 2016, there were 490,000 cases of multi-drug resistant TB globally. Over 2 billion people have asymptomatic latent Mycobacterium tuberculosis infection. TB represents an important, but neglected management issue in patients presenting to intensive care units. Tuberculosis in intensive care settings may present as the primary diagnosis (active drug sensitive or resistant TB disease). In other patients TB may be an incidental co-morbid finding as previously undiagnosed sub-clinical or latent TB which may re-activate under conditions of stress and immunosuppression. In Sub-Saharan Africa, where co-infection with the human immunodeficiency virus and other communicable diseases is highly prevalent, TB is one of the most frequent clinical management issues in all healthcare settings. Acute respiratory failure, septic shock and multi-organ dysfunction are the most common reasons for intensive care unit admission of patients with pulmonary or extrapulmonary TB. Poor absorption of anti-TB drugs occurs in critically ill patients and worsens survival. The mortality of patients requiring intensive care is high. The majority of early TB deaths result from acute cardiorespiratory failure or septic shock. Important clinical presentations, management and infection control issues regarding TB in intensive care settings are reviewed. •Acute respiratory failure, septic shock and multi-organ dysfunction are the most common reasons for intensive care unit admission of adult and paediatric patients with active tuberculosis.•The mortality of patients with confirmed TB requiring intensive care is high (up to 68.7%).•Infection with multi-drug and extensively resistant strains of Mycobacterium tuberculosis carries an exceptionally high mortality and is a growing challenge in many parts of the world.•To avoid inadequate intestinal drug absorption administer anti-tuberculosis drugs intravenously until gastrointestinal function is restored.•Adjunctive steroid therapy reduces mortality in tuberculous meningitis and reduces constrictive pericarditis. It is unclear whether steroids may benefit other form of tuberculosis.

La faculté de thérapie respiratoire du CNA-Q s'est joint à la Division de périnatologie de l'Hôpital des femmes du Hamad Medical Corporation au Qatar pour élaborer et mettre en oeuvre un programme de perfectionnement professionnel à l'intention du personnel de thérapie respiratoire en place et à examiner la possibilité d'offrir une formation supérieure aux diplômés en thérapie respiratoire. Qatar is an oil and gas rich nation, with the third largest gas reserves and the second highest GDP per capita in the world and occupies the smaller Qatar Peninsula on the northeasterly coast of the Arabian Peninsula.1 The State of Qatar has seen unprecedented growth both in economy and population over the last decade. Doha, the capital city and major urban centre, is home to approximately one million people and the rate of growth continues to be close to 10% per annum.1,2 Doha is quickly becoming a centre for educational and research excellence and there is significant representation of post secondary institutions from North America including Weill-Cornell Medical College, University of Calgary School of Nursing and College of the North Atlantic - Qatar (CNAQ), which provides programs in the allied health professions. Women's Hospital has seen dramatic increases in obstetric services over the last five years and currently inborn deliveries approach 15,000 live births per year.4 NICU admissions have steadily been on the increase, and in 2008, there were over 1,670 infants admitted to the NICU.4 Study of trends in perinatal and neonatal mortality rates in the State of Qatar are comparable with those in some of the developed countries.3,4 With the number of critically ill admissions and the intensive care required, a need was identified to ensure that respiratory therapy care services were current, evidenced based and incorporated best practices. Under the leadership and vision of the Director of NICU and partnered with CNAQ, a joint professional development program to enhance respiratory care of the neonate has been initiated. The goal is to provide professional development to existing and new respiratory therapy staff as well developing post graduate training for graduates of the Respiratory Therapy Program at CNAQ.

Abstract Background People living with HIV may be at increased risk for infections with resistant organisms. Infections with ESBL-producing organisms are of particular concern because they limit treatment options for severe Gram-negative infections in low-resource settings. Objectives To investigate the association between HIV status and urinary tract infections (UTIs) with ESBL-producing Escherichia coli. Patients and methods Cross-sectional study enrolling adults presenting with UTI symptoms to primary care clinics in Harare, Zimbabwe. Demographic and clinical data were collected during interviews and a urine sample was collected for culture from each participant. Antimicrobial susceptibility testing was performed according to EUCAST recommendations. Results Of the 1164 who were enrolled into the study, 783 (64%) were female and 387 (33%) were HIV infected. The median age was 35.8 years. Urine cultures were positive in 338 (29.0%) participants, and the majority of bacterial isolates were E. coli (n = 254, 75.2%). The presence of ESBL was confirmed in 49/254 (19.3%) E. coli. Participants with HIV had a 2.13 (95% CI 1.05–4.32) higher odds of infection with ESBL-producing E. coli than individuals without HIV. Also, the prevalence of resistance to most antimicrobials was higher among participants with HIV. Conclusions This study found an association between HIV and ESBL-producing E. coli in patients presenting with symptoms suggestive of UTI to primary care in Harare. HIV status should be considered when prescribing empirical antimicrobial treatment.

After the expenditure of millions of dollars, I was looking forward to the \"new\" market. But I was very disappointed. There seems no pattern to the new layout, almost a maze prompting the question \"how do we get out of here?\"

I have a large one in which we put all our kitchen waste, anything that will rot, plus the contents of a lot of neighbours bags. We save our newspapers for the Scouts and using our composter we have little garbage. Our blue box is filled mainly with cans, bottles etc. collected on my daily walks.

I realize the RBG has always had \"money problems\" and I applaud the work of the volunteers. However, as I witnessed new vehicles and equipment, designed sculptures, signs and structures, I became a bit suspicious. I wondered if the RBG might possibly be suffering to a degree from the same affliction as our hospitals, schools and other organizations that survive on taxes, grants and public donations.
