Abstract
BACKGROUND The COVID-19 pandemic resulted in the implementation of strict public health and social measures (PHSMs) (including mobility restrictions, social distancing, mask-wearing and hand hygiene), limitations on non-essential healthcare services, and public fear of COVID-19 infection, all of which potentially affected transmission and healthcare use for other diseases such as lower respiratory tract infections (LRTIs). OBJECTIVE To determine changes in LRTI hospital admissions and in-facility mortality in children aged <5 years in the Western Cape Province during the pandemic. METHODS We conducted a retrospective analysis of LRTI admissions and in-facility deaths from January 2019 to November 2021. We estimated changes in rates and trends of LRTI admissions during the pandemic compared with pre-pandemic period using interrupted time series analysis, adjusting for key characteristics. RESULTS There were 36 277 children admitted for LRTIs during the study period, of whom 58% were male and 51% were aged 28 days - 1 year. COVID-19 restrictions were associated with a 13% step reduction in LRTI admissions compared with the pre-COVID-19 period (incidence rate ratio (IRR) 0.87, 95% confidence interval (CI)) 0.80 - 0.94). The average LRTI admission trend increased on average by 2% per month during the pandemic (IRR 1.02, 95% CI 1.02 - 1.04). CONCLUSIONS The COVID-19 surges and their associated measures were linked to declining LRTI admissions and in-facility deaths, likely driven by a combination of reduced infectious disease transmission and reduced use of healthcare services, with effects diminishing over time. These findings may inform future pandemic response policies.

Abstract
BACKGROUND Routinely collected population-wide health data are often used to understand mortality trends including child mortality, as these data are often available more readily or quickly and for lower geographic levels than population-wide mortality data. However, understanding the completeness and accuracy of routine health data sources is essential for their appropriate interpretation and use. This study aims to assess the accuracy of diagnostic coding for public sector in-facility childhood (age < 5 years) infectious disease deaths (lower respiratory tract infections [LRTI], diarrhoea, meningitis, and tuberculous meningitis [TBM]) in routine hospital information systems (RHIS) through comparison with causes of death identified in a child death audit system (Child Healthcare Problem Identification Programme [Child PIP]) and the vital registration system (Death Notification [DN] Surveillance) in the Western Cape, South Africa and to calculate admission mortality rates (number of deaths in admitted patients per 1000 live births) using the best available data from all sources. METHODS The three data sources: RHIS, Child PIP, and DN Surveillance are integrated and linked by the Western Cape Provincial Health Data Centre using a unique patient identifier. We calculated the deduplicated total number of infectious disease deaths and estimated admission mortality rates using all three data sources. We determined the completeness of Child PIP and DN Surveillance in identifying deaths recorded in RHIS and the level of agreement for causes of death between data sources. RESULTS Completeness of recorded in-facility infectious disease deaths in Child PIP (23/05/2007-08/02/2021) and DN Surveillance (2010-2013) was 70% and 69% respectively. The greatest agreement in infectious causes of death were for diarrhoea and LRTI: 92% and 84% respectively between RHIS and Child PIP, and 98% and 83% respectively between RHIS and DN Surveillance. In-facility infectious disease admission mortality rates decreased significantly for the province: 1.60 (95% CI: 1.37-1.85) to 0.73 (95% CI: 0.56-0.93) deaths per 1000 live births from 2007 to 2020. CONCLUSION RHIS had accurate causes of death amongst children dying from infectious diseases, particularly for diarrhoea and LRTI, with declining in-facility admission mortality rates over time. We recommend integrating data sources to ensure the most accurate assessment of child deaths.

Abstract
Mutations in parkin are associated with various inherited forms of Parkinson's disease (PD). Parkin is a ubiquitin ligase enzyme that catalyzes the covalent attachment of ubiquitin moieties onto substrate proteins destined for proteasomal degradation. The substrates of parkin-mediated ubiquitination have yet to be completely identified. Using a yeast two-hybrid screen, we isolated the septin, human SEPT5_v2 (also known as cell division control-related protein 2), as a putative parkin-binding protein. SEPT5_v2 is highly homologous to another septin, SEPT5, which was recently identified as a target for parkin-mediated ubiquitination. SEPT5_v2 binds to parkin at the amino terminus and in the ring finger domains. Several lines of evidence have validated the putative link between parkin and SEPT5_v2. Parkin co-precipitates with SEPT5_v2 from human substantia nigra lysates. Parkin ubiquitinates SEPT5_v2 in vitro, and both SEPT5_v1 and SEPT5_v2 accumulate in brains of patients with ARJP, suggesting that parkin is essential for the normal metabolism of these proteins. These findings suggest that an important relationship exists between parkin and septins.

Abstract
A determination of the angular distribution parameter beta of the atomic chlorine 3s photoelectrons over the photon-energy range from 29 to 70 eV has been carried out using electron spectrometry in conjunction with synchrotron radiation. Our results confirm the basic theoretical predictions that beta, for s-subshell photoionization in open-shell atoms, is in general term and photon-energy dependent, in contrast to closed-shell atoms where beta is always 2 nonrelativistically. However, our measurements of beta for the Cl+ 3s((1,3)P) channels demonstrate that significant details are not handled well by simple Hartree-Fock theory.

Abstract
BACKGROUND Somatostatin receptors are present on many types of epithelial tumors, and ligands targeting these receptors are used to treat patients with neuroendocrine malignancies. Preclinical studies have demonstrated the presence of somatostatin receptors on a variety of mesenchymal tumors by in vitro receptor autoradiography. The use of radiolabeled somatostatin analogs to assess the presence of somatostatin receptors in vivo has been established, but use of this technique to evaluate human sarcomas has not been reported previously. METHODS Seventeen patients (13 females and 4 males) with metastatic sarcoma underwent imaging via somatostatin-receptor scintigraphy. Scans were performed using indium -111 pentetreotide. Planar studies and single photon emission computed tomography imaging were performed at 4 and 24 hours, and results of scintigraphy were correlated with computed tomography findings. RESULTS Twelve of 17 scans showed increased uptake in regions of known metastatic disease. There was no apparent correlation with scan positivity and patient age, histology, site of disease, or duration of diagnosis. CONCLUSIONS Seventy-one percent of patients with advanced soft-tissue sarcomas had positive scintigraphy scans demonstrating tumor expression of somatostatin receptors subtype 2 in vivo. Imaging with indium-111 pentetreotide could be studied as an adjunct to conventional imaging modalities for assessment of sarcoma patients. Further research is needed to determine the prognostic implications of somatostatin receptor subtype 2 positivity, including larger studies to evaluate any potential correlation with metastatic behavior and other clinical outcomes.

Abstract
PURPOSE To compare the efficacy and safety of ciprofloxacin (CIP) and trimethoprim/sulfamethoxazole (TMS) for the prevention of bacterial infections in patients who received bone marrow transplantation (BMT) for the treatment of solid and hematopoietic neoplasms. PATIENTS AND METHODS Adult inpatients about to undergo BMT for lymphoma, leukemia, or solid tumors were enrolled onto a prospective, randomized, double-blinded, controlled trial that compared CIP (750 mg orally twice per day) with TMS (160 mg trimethoprim and 800 mg sulfamethoxazole orally twice per day). Subjects were stratified before randomization according to tumor and BMT type. Prophylaxis was begun within 96 hours of initiation of the BMT preparative regimen and continued until the onset of fever, signs or symptoms of infection, serious adverse effects, or recovery of the absolute granulocyte count (AGC) to > or = to 400/microL. RESULTS Seventy-five CIP recipients and 71 TMS recipients were assessable for efficacy. No difference was noted between the two groups in occurrence of fever during neutropenia, time to onset of first fever, or overall infection rates. Ten bacteremias occurred in CIP recipients versus six in TMS recipients (P = .43). Ten episodes of Clostridium difficile enterocolitis occurred in TMS recipients versus no episodes in CIP recipients (P = .001). Four infections caused by gram-negative bacilli, including one bacteremia, occurred in TMS recipients versus none in CIP recipients (P = .06). No differences were noted in the incidence of rash or organ toxicity. TMS recipients had longer durations of granulocytopenia at AGC levels < or = to 500/microL and < or = to 100/microL than did CIP recipients (P = .08 for both comparisons). Mean peak and trough serum levels of CIP decreased significantly between weeks 1 and 2 of prophylaxis. CONCLUSION CIP and TMS were equally safe and effective in the prevention of bacterial infections in BMT patients when the overall infection rate was used as the principal end point. TMS prophylaxis was associated with a higher incidence of C difficile enterocolitis and infections caused by gram-negative bacilli, as well as a trend toward prolongation of granulocytopenia.

Abstract
Twenty-six oncology patients, 25 of whom received bone marrow transplants, were enrolled in a prospective, randomized, double-blinded, placebo-controlled trial assessing the efficacy of ciprofloxacin, 750 mg p.o. b.i.d., for preventing bacterial infections during prolonged neutropenia. Treatment was begun within 48 hr of initiation of chemotherapy and continued until the absolute granulocyte count recovered to greater than or equal to 500/microliters, or until the onset of fever (greater than or equal to 38.3 degrees C). Seven evaluable subjects received ciprofloxacin, and 11 received placebo. Risk factors for infection were comparable in both groups. Fever occurred in all study subjects, but onset was delayed in ciprofloxacin recipients (median = 6 days after the fall of the absolute granulocyte count to less than or equal to 500/microliters vs. 3 days for placebo recipients, P = 0.01). No clinically or microbiologically documented infections occurred in ciprofloxacin recipients vs. 10 infections in placebo recipients (5 bacteremias, 4 skin/soft tissue infections, 1 urinary tract infection, P = 0.0003). Ciprofloxacin recipients required fewer days of therapeutic antimicrobials (median: 28 antibiotic-days vs. 49, P0.02). The bioavailability of ciprofloxacin appeared comparable to that found in previously published studies of normal volunteers and patients not receiving chemotherapy. Adverse effects and colonization by ciprofloxacin-resistant microorganisms were monitored, but the sample sizes were too small to permit meaningful conclusions about these safety parameters. Ciprofloxacin appears to be effective for preventing bacterial infections in neutropenic patients. Additional trials are needed to establish the optimal dose of ciprofloxacin and to compare its safety and efficacy with those of currently used prophylactic regimens.
