The 5th Wave Series Epub 42
Introduction: The coronavirus disease 2019 (COVID-19) first reported in Wuhan, China in December 2019 is a global pandemic that is threatening the health and wellbeing of people worldwide. To date there have been more than 274 million reported cases and 5.3 million deaths. The Omicron variant first documented in the City of Tshwane, Gauteng Province, South Africa on 9 November 2021 led to exponential increases in cases and a sharp rise in hospital admissions. The clinical profile of patients admitted at a large hospital in Tshwane is compared with previous waves.

Sixty two (63%) patients in COVID-19 wards had incidental COVID-19 following a positive SARS-CoV-2 PCR test . Only one third (36) had COVID-19 pneumonia, of which 72% had mild to moderate disease. The remaining 28% required high care or ICU admission. Fewer than half (45%) of patients in COVID-19 wards required oxygen supplementation compared to 99.5% in the first wave. The death rate in the face of an exponential increase in cases during the Omicron wave at the city and provincial levels shows a decoupling of cases and deaths
The contribution of the Church and of evangelization to the development of peoples concerns not only the struggle against material poverty and underdevelopment in the South of the world, but also concerns the North, which is prone to a moral and spiritual poverty caused by "overdevelopment."112 A certain way of thinking, uninfluenced by a religious outlook and widespread in some parts of today's world, is based on the idea that increasing wealth and the promotion of economic and technical growth is enough for people to develop on the human level. But a soulless development cannot suffice for human beings, and an excess of affluence is as harmful as excessive poverty. This is a "development model" which the North has constructed and is now spreading to the South, where a sense of religion as well as human values are in danger of being overwhelmed by a wave of consumerism.
We included studies, in any language, of people with SARS-CoV-2 diagnosed by RT-PCR that documented follow-up and symptom status at the beginning and end of follow-up or investigated the contribution to SARS-CoV-2 transmission of asymptomatic or presymptomatic infection. We included contact tracing and outbreak investigations, cohort studies, case-control studies, and mathematical modelling studies. We amended eligibility criteria after the third version of the review  in 2 ways. First, we excluded studies that only reported the proportion of presymptomatic SARS-CoV-2 because the settings and methods of these studies were very different and their results were too heterogeneous to summarise . Second, we aimed to reduce the risk of bias from studies with inclusion criteria based mainly on people with symptoms, which would systematically underestimate the proportion of people with asymptomatic infection. We therefore excluded the following study types: case series restricted to people already diagnosed and studies that did not report the number of people tested for SARS-CoV-2, from whom the study population was derived. We also excluded case reports and contact investigations of single individuals or families, and any study without sufficient follow-up (Box 1). Where data from the same study population were reported in multiple records, we extracted data from the most comprehensive report.
After the third version of the review , we developed a new tool to assess the risk of bias because the study designs of included studies have changed. In previous versions, we used items from tools to assess case series  and the prevalence of mental health disorders . The new tool assessed possible biases in studies of prevalence in general and COVID-19 in particular [4,30]. We developed signalling questions in the domains of selection (2 items), information (3 items), and selective reporting (1 item) biases (S2 Text). For mathematical modelling studies, we used a checklist for assessing relevance and credibility . Two authors independently assessed the risk of bias, using a customised online tool. A third reviewer resolved disagreements.
The ABR test was done on the left ear and the records were obtained through two channels. Interacustic EP25 instrument and ABR 3A insert earphone were used to evaluate for ABR threshold. Subdermal needle electrodes were used to record the responses. The active electrode was located at the vertex, in the midline of the scalp. The reference electrodes were located in both mastoid regions. The ground electrode was located on the glabella. The ABR test was done by 1000 click stimulus at a rate of 21 times/sc and 100 to 3000 Hz band-pass filters. Measurements were obtained at 70 dBnHL and decreased by increments of 20 dB until the threshold was approached, where 10 dB increments were instituted. Repeatibility was confirmed, and the test was performed twice to determinate threshold. ABR threshold was defined on the fifth wave.
An outbreak of coronavirus disease 2019 (COVID-19), now known to be caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), that began in China in December 2019 has since spread rapidly throughout the world . Different variants of SARS-CoV-2 have been identified, such as the Delta variant. The Omicron variant is a new, heavily mutated SARS-CoV-2 variant that was designated as a variant of concern by the World Health Organization on November 26, 2021 . The first confirmed Omicron variant was reported to WHO on November 24, 2021, from a sample collected in South Africa . In the general population in England, Omicron cases were reported to have a reduced risk of hospitalization, compared with Delta . To date, Japan has experienced 6 waves of infection, with the 6th wave beginning in January 2021 and mainly consisting of cases infected with the Omicron variant. In addition, vaccination against SARS-CoV2 has now become widespread in Japan, and new medicines, such as neutralizing antibodies or antiviral agents, have been developed and are being used clinically.
On the other hand, hemodialysis patients are at a high risk for the development of severe COVID-19, since factors identified as risk factors for severe COVID-19 are often present in these patients including old age, hypertension, cardiovascular comorbidity, and underlying diabetes mellitus. In addition, these patients also show impaired antiviral immune responses because of their impaired kidney functions. Hemodialysis patients with COVID-19 reportedly have a poor prognosis [5,6,7,8,9]. In the present study, we examined the clinical characteristics of hemodialysis patients with COVID-19 during the 6th wave of infection at our hospital.
Time course of the changes in the serum CRP level in the 6th wave group. Seven hemodialysis patients in the 6th wave group had CRP values above 9.34 mg/dL within 7 days after clinical onset, which was the cutoff for predicting critical (including death) outcomes, but none of these patients developed critical outcomes (1 moderate, 6 severe)
The limitations of this study were that it was designed as a retrospective cohort study, that all the study participants were from a single institution, and that the sample size was limited. To identify the prognosis factors of the disease severity for COVID-19, multivariate analyses are required. But we could not perform cause of small size of patients. We also could not perform ROC curve analysis to determine the optimum cutoff point for the maximum CRP for predicting a critical outcome in the 6th wave group because there were no patients who result in critical in the group.
10.35 Consider investigations for coronary artery disease in the presence of any of the following: atypical cardiac symptoms (e.g., unexplained dyspnea, chest discomfort); signs or symptoms of associated vascular disease including carotid bruits, transient ischemic attack, stroke, claudication, or peripheral arterial disease; or electrocardiogram abnormalities (e.g., Q waves).

The immune response is vital for the control and resolution of CoV infections, while it can also lead to immunopathogenesis, associated with the immune response out of control. The S proteins of Coronavirus binds to the host cells by ACE2, fusing to the membrane and release the viral RNA. The viral RNAs, as pathogen-associated molecular patterns (PAMPs), are detected by the pattern recognition receptors (PRRs). Usually, Toll-like receptor (TLR) 3, TLR7, TLR8, and TLR9 sense viral RNA and DNA in the endosome [60, 61]. The viral RNA receptor retinoic-acid inducible gene I (RIG-I) , cytosolic receptor melanoma differentiation-associated gene 5 (MDA5) and nucleotidyltransferase cyclic GMP-AMP synthase (cGAS)  are responsible for the recognition of viral RNA and DNA in the cytoplasm. These complex signalling recruit adaptors, including TIR-domain-containing adaptor protein including IFN-β (TRIF), mitochondrial antiviral-signalling protein (MAVS)  and stimulator of interferon genes protein (STING)  to trigger downstream cascades molecules, involving adaptor molecule MyD88 and lead to the activation of the transcription factor nuclear factor-κB (NF-κB) and interferon regulatory factor 3 (IRF3) and the production of type I Interferons (IFN-α /β) and a series of pro-inflammatory cytokines . Hence, virus-cell interactions produce a diverse set of immune mediators against the invading virus . Innate immunity is needed in a precise regulation to eliminate the virus, otherwise will result in immunopathology. A few plasma cytokines and chemokines were observed ascended in COVID-19 patients, including IL-1, IL-2, IL-4, IL-7, IL-10, IL-12, IL-13, IL-17, GCSF, macrophage colony-stimulating factor (MCSF), IP-10, MCP-1, MIP-1α, hepatocyte growth factor (HGF), IFN-γ and TNF-α [48, 68, 69]. Of note, an anatomy report of COVID-19 pneumonia corpse  indicated that COVID-19 caused an inflammatory response in the lower airway and led to lung injury. Collectively, the virus particles invade the respiratory mucosa firstly and infect other cells, triggering a series of immune responses and the production of cytokine storm in the body, which may be associated with the critical condition of COVID-19 patients.
