Assessment of the delayed repair of uncomplicated inguinal hernias in infants
CITATION: Botes, S. N. et al. 2020. Assessment of the delayed repair of uncomplicated inguinal hernias in infants. South African Journal of Surgery, 58(1), 18-21, doi:10.17159/2078-5151/2020/v58n1a3056The original publication is available at: http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0038-23612020000100007BACKGROUND: Potential strangulation of infant inguinal hernias is the main indication for their urgent repair. Lack of theatre time delays repair and prolongs hospitalisation. We report a series of patients with uncomplicated hernias who were discharged home to have their elective surgery at a later stage and assessed the outcomes of this approach
METHODS: A retrospective audit was performed of all infants with an inguinal hernia from January 2010 to June 2015. Incomplete records and infants operated after their first birthday were excluded. Two groups were identified; immediate surgery for infants with uncomplicated hernias, and delayed surgery for infants with uncomplicated hernias. Incarceration/ strangulation rates in the interim period were documented for the delayed group, and comparison made between the groups regarding perioperative and anaesthetic complications and length of postoperative hospital stay
RESULTS: The mean time delay between diagnosis and repair was 8.78 weeks. None of the hernias in the delay group strangulated while awaiting repair. There was no significant difference in the perioperative complications between the two groups. Out ofthe 70 cases in the immediate repair group, there was 7 (10%) surgical and 4 (5.7%) anaesthetic complications. The delayed group (169 infants) had 8 (4.7%) surgical and 6 (3.6%) anaesthetic complications. The incarceration rate after being discharged home was 4.1%. This group of infants had no anaesthetic or surgical complications. Length of hospital stay postoperatively was 1.43 days in the immediate group and 1.3 in the delayed group (p = .485
CONCLUSION: Delayed repair, up to 2 months later, for uncomplicated infant hernia carries a small risk of incarceration but does not increase the rate of strangulation or other complicationsPublisher's versio
Legal and regulatory responses
Covid-19 pandemic posed a unique
challenge to legislatures and executives
worldwide, necessitating the development
of new regulations. This chapter evaluates
South Africa’s legal and regulatory response
to Covid-19 against the values enshrined in
section 1 of the Constitution. It considers the
options for managing the pandemic provided
by the Constitution and ordinary legislation
and evaluates the impact of the choice of the
Disaster Management Act.
Covid-19 has had a profound impact on and
challenged the maintenance of human
rights. The chapter reviews issues around human rights and governance within the legal
framework, as well as the ethical guidelines
that should frame responses to a pandemic. It
examines how consideration of the country’s
constitutional and democratic norms, values,
and safeguards (e.g., the rule of law, freedom
of expression, and human dignity) were
affected with respect to the right to healthcare,
education, a safe environment, and the like
during the management of the pandemic.
Rather than analysing specific regulations in
detail, the chapter focuses on three macro
issues: the rule of law, human rights, and
freedom of expression. The aim is to provide
a broad framework and set out principles
with which the law must comply during
emergency situations.This chapter 3.1 is published in the first edition of South Africa Covid-19 country report in June 2021.https://www.gov.za/sites/default/files/gcis_document/202206/sa-covid-19-reporta.pd
Conflict transformation in indigenous' peoples territories: doing environmental justice with a 'decolonial turn'
One of the distinctive features of environmental justice theory in Latin America is its influence by decolonial thought, which explains social and environmental injustices as arising from the project of modernity and the ongoing expansion of a European cultural imaginary. The decolonization of knowledge and social relations is highlighted as one of the key challenges for overcoming the history of violent oppression and marginalization in development and conservation practice in the region. In this paper we discuss how conflict transformation theory and practice has a role to play in this process. In doing so, we draw on the Socio-environmental Conflict Transformation (SCT) framework elaborated by Grupo Confluencias, which puts a focus on building community capacity to impact different spheres of power: people and networks, structures and cultural power. We discuss this framework and its practical use in the light of ongoing experiences with indigenous peoples in Latin America. We propose that by strengthening the power of agency of indigenous peoples to impact each of these spheres it is possible to build constructive intra and intercultural relations that can help increase social and environmental justice in their territories and thus contribute to decolonizing structures, relations and ways of being
Relative contribution of various chronic diseases and multi-morbidity to potential disability among Dutch elderly
BACKGROUND: The amount of time spent living with disease greatly influences elderly people’s wellbeing, disability
and healthcare costs, but differs by disease, age and sex.
METHODS: We assessed how various single and combined diseases differentially affect life years spent living with
disease in Dutch elderly men and women (65+) over their remaining life course. Multistate life table calculations
were applied to age and sex-specific disease prevalence, incidence and death rates for the Netherlands in 2007. We
distinguished congestive heart failure, coronary heart disease (CHD), breast and prostate cancer, colon cancer, lung
cancer, diabetes, COPD, stroke, dementia and osteoarthritis.
RESULTS: Across ages 65, 70, 75, 80 and 85, CHD caused the most time spent living with disease for Dutch men
(from 7.6 years at age 65 to 3.7 years at age 85) and osteoarthritis for Dutch women (from 11.7 years at age 65 to 4.
8 years at age 85). Of the various co-occurrences of disease, the combination of diabetes and osteoarthritis led to
the most time spent living with disease, for both men (from 11.2 years at age 65 to 4.9 -years at age 85) and
women (from 14.2 years at age 65 to 6.0 years at age 85).
CONCLUSIONS: Specific single and multi-morbid diseases affect men and women differently at different phases in the
life course in terms of the time spent living with disease, and consequently, their potential disability. Timely sex and
age-specific interventions targeting prevention of the single and combined diseases identified could reduce
healthcare costs and increase wellbeing in elderly people
A perspective on radical transformations to sustainability: resistances, movements and alternatives
A transformation to sustainability calls for radical and systemic societal shifts. Yet what this entails in practice and who the agents of this radical transformation are require further elaboration. This article recenters the role of environmental justice movements in transformations, arguing that the systemic, multi-dimensional and intersectional approach inherent in EJ activism is uniquely placed to contribute to the realization of equitable sustainable futures. Based on a perspective of conflict as productive, and a “conflict transformation” approach that can address the root issues of ecological conflicts and promote the emergence of alternatives, we lay out a conceptual framework for understanding transformations through a power analysis that aims to confront and subvert hegemonic power relations; that is, multi-dimensional and intersectional; balancing ecological concerns with social, economic, cultural and democratic spheres; and is multi-scalar, and mindful of impacts across place and space. Such a framework can help analyze and recognize the contribution of grassroots EJ movements to societal transformations to sustainability and support and aid radical transformation processes. While transitions literature tends to focus on artifacts and technologies, we suggest that a resistance-centred perspective focuses on the creation of new subjectivities, power relations, values and institutions. This recenters the agency of those who are engaged in the creation and recuperation of ecological and new ways of being in the world in the needed transformation

Recombinant Probiotic Expressing Listeria Adhesion Protein Attenuates Listeria monocytogenes Virulence In Vitro
BACKGROUND: Listeria monocytogenes, an intracellular foodborne pathogen, infects immunocompromised hosts. The primary route of transmission is through contaminated food. In the gastrointestinal tract, it traverses the epithelial barrier through intracellular or paracellular routes. Strategies to prevent L. monocytogenes entry can potentially minimize infection in high-risk populations. Listeria adhesion protein (LAP) aids L. monocytogenes in crossing epithelial barriers via the paracellular route. The use of recombinant probiotic bacteria expressing LAP would aid targeted clearance of Listeria from the gut and protect high-risk populations from infection. METHODOLOGY/PRINCIPAL FINDINGS: The objective was to investigate the ability of probiotic bacteria or LAP-expressing recombinant probiotic Lactobacillus paracasei (Lbp(LAP)) to prevent L. monocytogenes adhesion, invasion, and transwell-based transepithelial translocation in a Caco-2 cell culture model. Several wild type probiotic bacteria showed strong adhesion to Caco-2 cells but none effectively prevented L. monocytogenes infection. Pre-exposure to Lbp(LAP) for 1, 4, 15, or 24 h significantly (P<0.05) reduced adhesion, invasion, and transepithelial translocation of L. monocytogenes in Caco-2 cells, whereas pre-exposure to parental Lb. paracasei had no significant effect. Similarly, Lbp(LAP) pre-exposure reduced L. monocytogenes translocation by as much as 46% after 24 h. Lbp(LAP) also prevented L. monocytogenes-mediated cell damage and compromise of tight junction integrity. Furthermore, Lbp(LAP) cells reduced L. monocytogenes-mediated cell cytotoxicity by 99.8% after 1 h and 79% after 24 h. CONCLUSIONS/SIGNIFICANCE: Wild type probiotic bacteria were unable to prevent L. monocytogenes infection in vitro. In contrast, Lbp(LAP) blocked adhesion, invasion, and translocation of L. monocytogenes by interacting with host cell receptor Hsp60, thereby protecting cells from infection. These data show promise for the use of recombinant probiotics in preventing L. monocytogenes infection in high-risk populations

The FANCM:p.Arg658* truncating variant is associated with risk of triple-negative breast cancer
Breast cancer is a common disease partially caused by genetic risk factors. Germline pathogenic variants in DNA repair genes BRCA1, BRCA2, PALB2, ATM, and CHEK2 are associated with breast cancer risk. FANCM, which encodes for a DNA translocase, has been proposed as a breast cancer predisposition gene, with greater effects for the ER-negative and triple-negative breast cancer (TNBC) subtypes. We tested the three recurrent protein-truncating variants FANCM:p.Arg658*, p.Gln1701*, and p.Arg1931* for association with breast cancer risk in 67,112 cases, 53,766 controls, and 26,662 carriers of pathogenic variants of BRCA1 or BRCA2. These three variants were also studied functionally by measuring survival and chromosome fragility in FANCM−/− patient-derived immortalized fibroblasts treated with diepoxybutane or olaparib. We observed that FANCM:p.Arg658* was associated with increased risk of ER-negative disease and TNBC (OR = 2.44, P = 0.034 and OR = 3.79; P = 0.009, respectively). In a country-restricted analysis, we confirmed the associations detected for FANCM:p.Arg658* and found that also FANCM:p.Arg1931* was associated with ER-negative breast cancer risk (OR = 1.96; P = 0.006). The functional results indicated that all three variants were deleterious affecting cell survival and chromosome stability with FANCM:p.Arg658* causing more severe phenotypes. In conclusion, we confirmed that the two rare FANCM deleterious variants p.Arg658* and p.Arg1931* are risk factors for ER-negative and TNBC subtypes. Overall our data suggest that the effect of truncating variants on breast cancer risk may depend on their position in the gene. Cell sensitivity to olaparib exposure, identifies a possible therapeutic option to treat FANCM-associated tumors
