Within-Compound Versus Public Latrine Access and Child Feces Disposal Practices in Low-Income Neighborhoods of Accra, Ghana.
In crowded urban settlements in low-income countries, many households rely on shared sanitation facilities. Shared facilities are not currently considered "improved sanitation" because of concerns about whether hygiene conditions sufficiently protect users from the feces of others. Prevention of fecal exposure at a latrine is only one aspect of sanitary safety. Ensuring consistent use of latrines for feces disposal, especially child feces, is required to reduce fecal contamination in households and communities. Household crowding and shared latrine access are correlated in these settings, rendering latrine use by neighbors sharing communal living areas as critically important for protecting one's own household. This study in Accra, Ghana, found that household access to a within-compound basic latrine was associated with higher latrine use by children of ages 5-12 years and for disposal of feces of children < 5 years, compared with households using public latrines. However, within-compound access was not associated with improved child feces disposal by other caregivers in the compound. Feces was rarely observed in household compounds but was observed more often in compounds with latrines versus compounds relying on public latrines. Escherichia coli and human adenovirus were detected frequently on household surfaces, but concentrations did not differ when compared by latrine access or usage practices. The differences in latrine use for households sharing within-compound versus public latrines in Accra suggest that disaggregated shared sanitation categories may be useful in monitoring global progress in sanitation coverage. However, compound access did not completely ensure that households were protected from feces and microbial contamination
Assessment of Fecal Exposure Pathways in Low-Income Urban Neighborhoods in Accra, Ghana: Rationale, Design, Methods, and Key Findings of the SaniPath Study.
Rapid urbanization has contributed to an urban sanitation crisis in low-income countries. Residents in low-income, urban neighborhoods often have poor sanitation infrastructure and services and may experience frequent exposure to fecal contamination through a range of pathways. There are little data to prioritize strategies to decrease exposure to fecal contamination in these complex and highly contaminated environments, and public health priorities are rarely considered when planning urban sanitation investments. The SaniPath Study addresses this need by characterizing pathways of exposure to fecal contamination. Over a 16 month period, an in-depth, interdisciplinary exposure assessment was conducted in both public and private domains of four neighborhoods in Accra, Ghana. Microbiological analyses of environmental samples and behavioral data collection techniques were used to quantify fecal contamination in the environment and characterize the behaviors of adults and children associated with exposure to fecal contamination. Environmental samples (n = 1,855) were collected and analyzed for fecal indicators and enteric pathogens. A household survey with 800 respondents and over 500 hours of structured observation of young children were conducted. Approximately 25% of environmental samples were collected in conjunction with structured observations (n = 441 samples). The results of the study highlight widespread and often high levels of fecal contamination in both public and private domains and the food supply. The dominant fecal exposure pathway for young children in the household was through consumption of uncooked produce. The SaniPath Study provides critical information on exposure to fecal contamination in low-income, urban environments and ultimately can inform investments and policies to reduce these public health risks

The Social Significance of Spirituality: New Perspectives on the Compassion-Altruism Relationship
In the current research we tested a comprehensive model of spirituality, religiosity, compassion, and altruism, investigating the independent effects of spirituality and religiosity on compassion and altruism. We hypothesized that, even though spirituality and religiosity are closely related, spirituality and religiosity would have different and unique associations with compassion and altruism. In Study 1 and 2 we documented that more spiritual individuals experience and show greater compassion. The link between religiosity and compassion was no longer significant after controlling for the impact of spirituality. Compassion has the capacity to motivate people to transcend selfish motives and act altruistically towards strangers. Therefore, we reasoned that spirituality (but not religiosity) would predict altruistic behavior and that compassion would help explain this link. Indeed, in Studies 3, 4, and 5 we found that more spiritual individuals behaved more altruistically in economic choice and decision-making tasks, and that the tendency of spiritual individuals to feel greater compassion mediated the spirituality-to-altruism relationship. In contrast, more religious participants did not consistently feel more compassion nor behave more altruistically. Moreover, in Studies 3 and 4 we found that the broader traits of Agreeableness, Openness, and Extraversion did not help explain why more spiritual individuals behaved more altruistically. Our findings argue that spirituality—above and beyond religiosity—is uniquely associated with greater compassion and enhanced altruism towards strangers.Keywords: altruism, behavioral economics, religion, spirituality, compassio
Carbapenem resistance expressed by Gram-negative bacilli isolated from a cohort of Libyan patients
Background and objectives: Carbapenem-resistant Enterobacteriaceae (CRE) and other Gram-negative bacteria are among the most common pathogens responsible for both community and hospital acquired infection. The global spread of cephalosporinases in Enterobacteriaceae has led to the increased use of carbapenems resulting in the emergence and rapid spread of CRE. This has become an alarming public health
concern, yet the condition in Libya remains unclear. The aim of this study was to obtain a better understanding of CRE strains prevalent
in Libyan patients by investigating their phenotypic characteristics and antibiograms.
Methods: Gram-negative bacterial species were collected from Misrata Central Hospital, Misrata Cancer Centre and Privet Pathology Laboratories. Clinical samples and swabs were obtained from hospitalised and non-hospitalised patients and from mechanical ventilation and suction machines. Patients who had received antibiotic therapy for at least three days prior to the study were excluded. The identification and characterization of the isolated species were achieved using the growth characteristics on MacConkey and blood agar,
spot tests and API 20E or API 20NE biochemical testing systems. Screening for carbapenem resistance was performed using the disk
diffusion method with carbapenem 10 μg and cephalosporin 30 μg disks and minimum inhibitory concentrations (MIC) determined
using the Sensititre Gram-negative Xtra plate format (GNX2F). All strains demonstrating resistance or reduced susceptibility to one of
the four carbapenems were subjected to carbapenememase activity detection using the RAPIDEC CARBA NP test, Modified Hodge test
and carbapenem inactivation methods.
Results: A total of one hundred and forty isolates representing fourteen bacterial species were isolated from 140 non-duplicated specimens.
Clinical specimens included urine samples (96/140, 68.57%), sputum (15/140, 10.71%), surgical wound swabs (18/140, 12.85%),
foot swabs from diabetes mellitus (DM) patients (6/140, 4.29%), ear swabs (3/140, 2.14%) and wound swabs (2/140, 1.43%). Thirty-four
(24.29%) isolates demonstrated resistance to at least one of the four carbapenems with Klebsiella pneumoniae representing 73.53%
(25 isolates) of all carbapenem resistant species, followed by 8.82% for Pseudomonas aeruginosa (3 isolates), 5.88% for both Proteus
mirabilis (2 isolates) and Escherichia coli (2 isolates) and 2.94% for both Citrobacter koseri (1 isolate) and Rahnella aquatilis (1 isolate).
The other isolates were either susceptible or cephalosporinase producers.
Conclusion: This study has revealed the high rate of carbapenem resistance amongst Libyan patients and emphasizes the crucial need for accurate screening, identification and susceptibility testing to prevent further spread of nosocomial and community acquired resistance.
This may be achieved through the establishment of antibiotic stewardship programmes along with firm infection control practices.National Research Foundation of South Africa;

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study
Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown
Bridging pre-surgical endocrine therapy for breast cancer during the COVID-19 pandemic: outcomes from the B-MaP-C study
Purpose:
The B-MaP-C study investigated changes to breast cancer care that were necessitated by the COVID-19 pandemic. Here we present a follow-up analysis of those patients commenced on bridging endocrine therapy (BrET), whilst they were awaiting surgery due to reprioritisation of resources.
Methods:
This multicentre, multinational cohort study recruited 6045 patients from the UK, Spain and Portugal during the peak pandemic period (Feb–July 2020). Patients on BrET were followed up to investigate the duration of, and response to, BrET. This included changes in tumour size to reflect downstaging potential, and changes in cellular proliferation (Ki67), as a marker of prognosis.
Results:
1094 patients were prescribed BrET, over a median period of 53 days (IQR 32–81 days). The majority of patients (95.6%) had strong ER expression (Allred score 7–8/8). Very few patients required expedited surgery, due to lack of response (1.2%) or due to lack of tolerance/compliance (0.8%). There were small reductions in median tumour size after 3 months’ treatment duration; median of 4 mm [IQR − 20, 4]. In a small subset of patients ( n = 47), a drop in cellular proliferation (Ki67) occurred in 26 patients (55%), from high (Ki67 ≥ 10%) to low (< 10%), with at least one month’s duration of BrET.
Discussion:
This study describes real-world usage of pre-operative endocrine therapy as necessitated by the pandemic. BrET was found to be tolerable and safe. The data support short-term (≤ 3 months) usage of pre-operative endocrine therapy. Longer-term use should be investigated in future trials

Further Inspection: Leveraging Housing Inspectors and City Data to Improve Public Health in Chelsea, MA
Substandard housing represents an important and growing public health problem. It is associated with higher rates of mental illness, chronic and infectious disease, and other negative outcomes. Housing inspectors, by nature of their work inside homes and close contact with residents, are some of the only public officials to witness these risks. Early intervention can reduce public health risks and reduce costs to governments and society. However, current housing inspection focuses on technical enforcement of housing codes rather than broader socioeconomic or health impacts that the codes were originally designed to address. Further, the potential for early intervention is limited because 1) cities are not aware of problems soon enough, as inspection is often reactive or relies on tacit knowledge, and 2) housing inspectors lack systems to respond to the range of public health risks they encounter. In response to these problems, the objective of my DrPH dissertation was to:
1) Develop and implement a social-service referral innovation within a city’s inspectional services department that leverages the unique role of housing inspectors to link at-risk residents with social services, and
2) Develop an approach to using city data to identify and prioritize the response to prevalent housing-related health threats.
I carried out this work in Chelsea, Massachusetts, in collaboration with Chelsea City Hall and other City agencies. The goal is that the complex public health risks related to substandard housing are reduced because the City is aware of problems sooner and housing inspectors respond with both enforcement and service provision interventions.
I drew from action research methods, a process of systematic inquiry that is collaborative, reflective, and participatory. The result was a sub-contract between City Hall and a local social-service agency to respond to referrals from housing inspectors and intervene early on problems that cannot be resolved through code enforcement alone. Further, through aggregating and analyzing City data, I identified housing-related public health problems and ways to improve efficiency, effectiveness, and equity of code enforcement. In this dissertation, I capture the lessons learned, describe the impact achieved, and lay a conceptual foundation for future inquiry and public health change.Public Healt
