  Coronavirus disease 2019 (COVID-19) has wreaked health and economic damage globally. A thorough understanding of the characteristics of COVID-19 patients in Australia plus the strategies that successfully 'flatten the curve' are vitally important to contain this pandemic.
 
  To describe the clinical characteristics and outcomes of COVID-19 patients in the Sutherland Shire, and the management model adopted to manage these patients.
 
  A retrospective case series of COVID-19 patients monitored in the Sutherland Shire between 19 March and 15 May 2020 was performed. Demographic, clinical and outcome data of COVID-19 inpatients at the Sutherland Hospital and demographic data of COVID-19 patients in the Sutherland Shire community were obtained. The Sutherland Hospital COVID-19 Management Model involved close collaboration among the Sutherland Fever Clinic, Sutherland COVID-19 community telemonitoring team (CTAC) and Sutherland COVID-19 inpatient team.
 
  Ninety-nine COVID-19 cases (median age, 49 years, 50 (51%) male) were monitored in Sutherland Shire, with 19 cases (median age, 54 years, 10 (53%) male) requiring inpatient management. Common comorbidities included obesity, asthma, hypertension and Type 2 diabetes mellitus. Six (32%) patients required supplemental oxygen and three (16%) patients required intensive care admission. There was one mortality. The CTAC team identified five (5%) patients requiring admission, and three (3%) patients requiring re-admission. The majority of COVID-19 source was from overseas travel (67%), with nine (9%) cases having unknown source.
 
  A comprehensive COVID-19 management model is needed to successfully manage COVID-19 patients in both outpatient and inpatient settings in order to 'squash the curve'.

In order to achieve efficient and selective C-H functionalization, different strategies have been used to accelerate the C-H activation step, including the incorporation of directing groups in the substrate that facilitate coordination to the catalyst. In this review, we try to underscore that the understanding the mechanisms of the catalytic cycle and the reactivity or redox activity of the key metal cyclic intermediates in these reactions is the basis for controlling the selectivity of synthesis and electrosynthesis. Combination of the electrosynthesis and voltammetry with traditional synthetic and physico-chemical methods allows one to achieve selective transformation of C-H bonds to functionalized C-C or C-X (X=heteroatom or halogen) bonds which may encourage organic chemists to use it in the future more often. The possibilities and the benefits of electrochemical techniques are analyzed and summarized.Globally, collapse of ecosystems-potentially irreversible change to ecosystem structure, composition and function-imperils biodiversity, human health and well-being. We examine the current state and recent trajectories of 19 ecosystems, spanning 58° of latitude across 7.7 M km2 , from Australia's coral reefs to terrestrial Antarctica. Pressures from global climate change and regional human impacts, occurring as chronic 'presses' and/or acute 'pulses', drive ecosystem collapse. Ecosystem responses to 5-17 pressures were categorised as four collapse profiles-abrupt, smooth, stepped and fluctuating. The manifestation of widespread ecosystem collapse is a stark warning of the necessity to take action. We present a three-step assessment and management framework (3As Pathway Awareness, Anticipation and Action) to aid strategic and effective mitigation to alleviate further degradation to help secure our future.Fine needle aspiration (FNA) is a minimally invasive technique used in the initial diagnosis of superficial lesions, including lymphadenopathy. Its benefit in lymph node pathology, however, is highly variable, especially in heterogeneous lymphoproliferative disorders like angioimmunoblastic T-cell lymphoma (AITL). AITL is an aggressive hematopoietic malignancy, histologically characterized by medium-sized neoplastic cells, high endothelial venule proliferations, and a heterogeneous hematolymphoid background.  https://www.selleckchem.com/products/mrtx1133.html  Diagnostic difficulty arises at lymph node FNA, where cytology yields nonspecific polymorphous collections of medium-sized lymphocytes, hematolymphoid cells, dendritic cell-lymphoid complexes, and lymphoid tissue fragments with transgressing blood vessels; findings mimicking reactive lymphadenopathy. We present a case of a 62-year-old male who presented with cervical lymphadenopathy. Neck level II lymph node FNA revealed granulomatous inflammation. A cell block was prepared for additional infectious studies but was non-contributory due to lack of material. Flow cytometry showed no evidence of non-Hodgkin lymphoma. Excisional biopsy revealed lymph node effacement by a T-cell lymphoproliferative disorder consistent with AITL. This case contributes to the paucity of literature regarding the cytologic features of AITL observed at FNA, and becomes the premier case to emphasize the addition of granulomatous features. Despite the aggressive nature of this entity, cases are frequently misdiagnosed as reactive on initial evaluation resulting in delay of treatment. This report serves to raise suspicion of AITL and other polymorphic cellular lymphomas in the setting of reactive granulomatous cytomorphology, thus prompting histological examination of tissue biopsy, expediting treatment, and ultimately providing potential improvement to the current prognosis.Several signaling pathways were involved in M1 (classic) and M2 (alternative) macrophage polarization. Disruption of M2-related signaling pathways and improvement of M1-related signaling pathways can be identified as one of the cancer therapeutic approaches. Prevention of macrophage differentiation into M2 by different herbal agents with antitumor properties can be considered as a promising therapeutic target for cancer patients. In the present review study, we investigated the effect of herbal compounds on M1 and M2 related signaling pathways to reduce M2 and increase M1 macrophage polarization for the treatment of different types of cancer.
