Getting it Wrong: Applying Public Security Limitation to the East African Community\u27s Right of Establishment in Kenya

The Right of Establishment (ROE) is one of the rights and freedoms provided for under the East African Community’s Common Market Protocol. Under this right, citizens of East African Community Partner States, namely, Kenya, Uganda, Tanzania, Rwanda, Burundi, South Sudan, and the Democratic Republic of Congo are entitled to move to any other Partner State and pursue economic activities, as self-employed persons. Their spouses and children are also entitled to this right or to be employed. They are also entitled to join the security schemes of the host PS. However, the right is not absolute. A PS can limit the enjoyment of the right on the ground of public security. The “how” of applying the limitation was left to the Partner States to deal with under their national laws. This article analyses how Kenya handles this limitation regarding East African Community citizens, who are ROE holders. It examines the scope of the limitation focusing on its theoretical underpinning, and its scope under the Common Market Protocol. It then identifies and explains areas where Kenya is getting it ‘wrong’. The article contends that Kenya has not balanced the interests of ROE holders and its national interests. It suggests steps towards getting it right during the application of the limitation

Sequencing of chemotherapy and radiotherapy for early breast cancer (Review)

Background: After surgery for localised breast cancer, radiotherapy (RT) improves both local control and breast cancer-specific survival. In patients at risk of harbouring micro-metastatic disease, adjuvant chemotherapy (CT) improves 15-year survival. However, the best sequence of administering these two types of adjuvant therapy for early-stage breast cancer is unclear. Objectives: To determine the effects of different sequencing of adjuvant CT and RT for women with early breast cancer. Search methods: An updated search was carried out in the Cochrane Breast Cancer Group's Specialised Register (20 May 2011), MEDLINE (14 December 2011), EMBASE (20 May 2011) and World Health Organization (WHO) International Clinical Trials Registry Platform (20 May 2011). Details of the search strategy and methods of coding for the Specialised Register are described in the Group's module in The Cochrane Library. We extracted studies that had been coded as 'early', 'chemotherapy' and 'radiotherapy'. Selection criteria: We included randomised controlled trials evaluating different sequencing of CT and RT. Data collection and analysis: We assessed the eligibility and quality of the identified studies and extracted data from the published reports of the included trials. We derived odds ratios (OR) and hazard ratios (HR) from the available numerical data. Toxicity data were extracted, where reported. We used a fixed-effect model for meta-analysis and conducted analyses on the basis of the method of sequencing of the two treatments. Main results: Three trials reporting two different sequencing comparisons were identified. There were no significant differences between the various methods of sequencing adjuvant therapy for local recurrence-free survival, overall survival, relapse-free survival and metastasis-free survival based on 1166 randomised women in three trials. Concurrent chemoradiation increased anaemia (OR 1.54; 95% confidence interval (CI) 1.10 to 2.15), telangiectasia (OR 3.85; 95% CI 1.37 to 10.87) and pigmentation (OR 15.96; 95% CI 2.06 to 123.68). Treated women did not report worse cosmesis with concurrent chemoradiation but physician-reported assessments did (OR 1.14; 95% CI 0.42 to 3.07). Other measures of toxicity did not differ between the two types of sequencing. On the basis of one trial (244 women), RT before CT was associated with an increased risk of neutropenic sepsis (OR 2.96; 95% CI 1.26 to 6.98) compared with CT before RT, but other measures of toxicity did not differ. Authors' conclusions: The data included in this review, from three well-conducted randomised trials, suggest that different methods of sequencing CT and RT do not appear to have a major effect on recurrence or survival for women with breast cancer if RT is commenced within seven months after surgery

CASSETTE—clindamycin adjunctive therapy for severe Staphylococcus aureus treatment evaluation: Study protocol for a randomised controlled trial

Background Exotoxins are important virulence factors in Staphylococcus aureus. Clindamycin, a protein synthesis inhibitor antibiotic, is thought to limit exotoxin production and improve outcomes in severe S. aureus infections. However, randomised prospective data to support this are lacking. Methods An open-label, multicentre, randomised controlled trial (RCT) will compare outcome differences in severe S. aureus infection between standard treatment (flucloxacillin/cefazolin in methicillin-susceptible S. aureus; and vancomycin/daptomycin in methicillin-resistant S. aureus) and standard treatment plus an additional clindamycin given for 7 days. We will include a minimum of 60 participants (both adult and children) in the pilot study. Participants will be enrolled within 72 h of an index culture. Severe infections will include septic shock, necrotising pneumonia, or multifocal and non-contiguous skin and soft tissue/osteoarticular infections. Individuals who are immunosuppressed, moribund, with current severe diarrhoea or Clostridiodes difficile infection, pregnant, and those with anaphylaxis to β-lactams or lincosamides will be excluded. The primary outcomes measure is the number of days alive and free (1 or 0) of systemic inflammatory response syndrome (SIRS) within the first 14 days post randomisation. The secondary outcomes measure will include all-cause mortality at 14, 42, and 90 days, time to resolution of SIRS, proportion with microbiological treatment failure, and rate of change of C-reactive protein over time. Impacts of inducible clindamycin resistance, strain types, methicillin susceptibility, and presence of various exotoxins will also be analysed. Discussion This study will assess the effect of adjunctive clindamycin on patient-centred outcomes in severe, toxin-mediated S. aureus infections. The pilot study will provide feasibility for a much larger RCT. Trial registration Australian New Zealand Clinical Trials Registry, ACTRN12617001416381p. Registered on 6 October 2017

Clindamycin adjunctive therapy for severe Staphylococcus aureus treatment evaluation (CASSETTE)—an open-labelled pilot randomized controlled trial

Background Combination antibiotic therapy with an antitoxin agent, such as clindamycin, is included in some guidelines for severe, toxin-mediated Staphylococcus aureus infections. The evidence to support this practice is currently limited to in vitro, animal and observational human case-series data, with no previous randomized controlled trials (RCTs). Objectives This pilot RCT aimed to determine the feasibility of conducting a clinical trial to examine if adjunctive clindamycin with standard therapy has greater efficacy than standard therapy alone for S. aureus infections. Methods We performed an investigator-initiated, open-label, multicentre, pilot RCT (ACTRN12617001416381p) in adults and children with severe S. aureus infections, randomized to standard antibiotic therapy with or without clindamycin for 7 days. Results Over 28 months, across nine sites, 127 individuals were screened and 34 randomized, including 11 children (32%). The primary outcome—number of days alive and free of systemic inflammatory response syndrome ≤14 days—was similar between groups: clindamycin (3 days [IQR 1–6]) versus standard therapy (4 days [IQR 0–8]). The 90 day mortality was 0% (0/17) in the clindamycin group versus 24% (4/17) in the standard therapy group. Secondary outcomes—microbiological relapse, treatment failure or diarrhoea—were similar between groups. Conclusions As the first clinical trial assessing adjunctive clindamycin for S. aureus infections, this study indicates feasibility and that adults and children can be incorporated into one trial using harmonized endpoints, and there were no safety concerns. The CASSETTE trial will inform the definitive S. aureus Network Adaptive Platform (SNAP) trial, which includes an adjunctive clindamycin domain and participants with non-severe disease

Application of ripple mapping to visualize slow conduction channels within the infarct-related left ventricular scar

Background - Ripple mapping (RM) displays each electrogram at its 3-dimensional coordinate as a bar changing in length according to its voltage-time relationship with a fiduciary reference. We applied RM to left ventricular ischemic scar for evidence of slow-conducting channels that may act as ventricular tachycardia (VT) substrate. Methods and Results - CARTO-3(Biosense Webster Inc, Diamond Bar, CA) maps in patient undergoing VT ablation were analyzed on an offline MatLab RM system. Scar was assessed for sequential movement of ripple bars, during sinus rhythm or pacing, which were distinct from surrounding tissue and termed RM conduction channels (RMCC). Conduction velocity was measured within RMCCs and compared with the healthy myocardium (>1.5 mV). In 21 maps, 77 RMCCs were identified. Conduction velocity in RMCCs was slower when compared with normal left ventricular myocardium (median, 54 [interquartile range, 40-86] versus 150 [interquartile range, 120-160] cm/s; P<0.001). All 7 sites meeting conventional criteria for diastolic pathways coincided with an RMCC. Seven patients had ablation colocating to all identified RMCCs with no VT recurrence during follow-up (median, 480 [interquartile range, 438-841] days). Fourteen patients had \ue2\u89\ua51 RMCC with no ablation lesions. Five had recurrence during follow-up (median, 466 [interquartile range, 395-694] days). One of the 2 patients with no RMCC locations ablated had VT recurrence at 605 days post procedure. RMCCs were sensitive (100%; negative predictive value, 100%) for VT recurrence but the specificity (43%; positive predictive value, 35.7%) may be limited by blind alleys channels. Conclusions - RM identifies slow conduction channels within ischemic scar and needs further prospective investigation to understand the role of RMCCs in determining the VT substrate

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio
