Differences in leucocytes and inflammation-based indices among critically ill patients owing to SARS-CoV-2 variants during several successive waves of COVID-19 pandemic.

Background/aim: Inflammatory indices are useful informative markers in assessing the severity of the COVID-19 disease course; however, their involvements during series waves of SARS-CoV-2 virus outbreaks in critical patients with COVID-19 remain unclear. Hence, we aimed to ascertain the changing dynamics of the combined inflammatory indices (NLR, dNLR, CLR, LMR, PLR, SII, and SIRI) and their associations with clinical outcomes in severe COVID-19 patients during serial waves of SARS-CoV-2.

Patients And Methods: We retrospectively enrolled 163 severe COVID-19 patients admitted to the ICU during six SARS-CoV-2 waves.

Evaluating the biomethane potential from the anaerobic co-digestion of palm oil mill effluent, food waste, and sewage sludge in Malaysia.

The ever-increasing organic waste generation in Malaysia is a significant contributor to greenhouse gas (GHG) emissions. However, organic wastes can be utilized to produce biogas by anaerobic digestion, which is a promising option for both energy and material recovery from organic wastes with high moisture content. Therefore, this study was formulated to investigate the feasibility of anaerobic co-digestion of three types of organic wastes generated in significantly huge quantities in Malaysia, namely palm oil mill effluent (POME), food waste (FW), and sewage sludge (SWS).

[Pulmonary thromboembolism: incidence, physiopathology, diagnosis and treatment].

The objective of this work was to review current data about the pathophysiology, clinical features, and treatment of pulmonary thromboembolism. Venous thromboembolism (VTE) remains a major challenge in hospitalised especially the care of critically ill patients. Pulmonary embolism (PE) is the major complication of VTE.

[Use of catecholamines for shock. A continuous debate!].

Background: Hypotension and shocks are frequently observed in patients requiring admission in ICU. However, the optimal adrenergic support in shock is controversial.

Aim: To perform a descriptive approach of the current use of catecholamine in a medico-surgical ICU in patients with schoks.

Pulmonary edema following scorpion envenomation: mechanisms, clinical manifestations, diagnosis and treatment.

Scorpion envenomation is common in tropical and subtropical regions. Cardio-respiratory manifestations, mainly cardiogenic shock and pulmonary edema, are the leading causes of death after scorpion envenomation. The mechanism of pulmonary edema remains unclear and contradictory conclusions were published.

Epidemiological, clinical characteristics and outcome of severe scorpion envenomation in South Tunisia: multivariate analysis of 951 cases.

The aim of this retrospective descriptive study was to describe both epidemiologically and clinically manifestations following severe scorpion envenomation and to define simple predictive factors which can be used in routine practice in general Intensive Care Units (ICU) as an indicator of poor prognosis. Cases were collected from hospital patients' files during 13-year (1990-2002) period in the medical Intensive Care Unit of a university hospital (Sfax - Tunisia). The diagnosis of scorpion envenomation was based on a history of scorpion sting.
