Ceftolozane/tazobactam (C/T) is a combination of a novel cephalosporin with tazobactam, recently approved for the treatment of hospital-acquired and ventilator-associated pneumonia. The plasma pharmacokinetics (PK) of a 3-g dose of C/T (2 g ceftolozane and 1 g tazobactam) administered via a 1-hour infusion every 8 hours in adult patients with nosocomial pneumonia (NP) were evaluated in a phase 3 study (ASPECT-NP; NCT02070757). The present work describes the development of population PK models for ceftolozane and tazobactam in plasma and pulmonary epithelial lining fluid (ELF). The concentration-time profiles of both agents were well characterized by 2-compartment models with zero-order input and first-order elimination. Consistent with the elimination pathway, renal function estimated by creatinine clearance significantly affected the clearance of ceftolozane and tazobactam. The central volumes of distribution for both agents and the peripheral volume of distribution for tazobactam were approximately 2-fold higher in patients with pneumonia compared with healthy participants. A hypothetical link model was developed to describe ceftolozane and tazobactam disposition in ELF in healthy participants and patients with pneumonia. Influx (from plasma to the ELF compartment) and elimination (from the ELF compartment) rate constants were approximately 97% lower for ceftolozane and 52% lower for tazobactam in patients with pneumonia versus healthy participants. These population PK models adequately described the plasma and ELF concentrations of ceftolozane and tazobactam, thus providing a foundation for further modeling and simulation, including the probability of target attainment assessments to support dose recommendations of C/T in adult patients with NP.The 2014-2016 Ebola outbreak in West Africa extracted huge health, social, and economic costs. How can lessons learnt during the 2014-2016 Ebola outbreak in West Africa help to mitigate the likelihood of a long-term devastating effect of the coronavirus disease (COVID-19) outbreak on the African continent? Despite COVID-19 spreading quickly across the globe after being first reported in Wuhan, China on December 31, 2019, African countries remained relatively unaffected until the second week of March 2020. The majority of Africa countries have been at low to moderate risk. However, they have experienced many sociocultural, economic, political, and structural challenges. These have included laboratory capacity and logistical challenges; ill-equipped public health systems; land border permeability, and delayed preparedness to transnational threats; and abject economic deprivation, lack of basic infrastructure, and associated sociocultural implications. There needs to be a strong country-level leadership to coordinate and own all aspects of the responses to the COVID-19 pandemic in a collaborative, transparent, and accountable way. Strategic and sustained response plans to fight the pandemic should incorporate culturally competent strategies that harness different cultural practices and strengthen cultural security.  https://www.selleckchem.com/products/pyrotinib.html  They should also promote and strengthen the implementation of the International Health Regulations.Extrusion processing characteristics of pea starch were studied as impacted by various extrusion cooking processing variables, including, moisture content (15%, 17.5%, and 20% w.b.), temperature (120, 135, and 150 °C), and screw speed (150, 200, and 250 rpm), in a co-rotating twin-screw extruder. Physicochemical properties such as radial expansion ratio (ER), unit density (UD), water absorption index (WAI), and water solubility index (WSI) were measured. ER of the extrudates ranged between 2.52 and 3.63. These values of ER were significantly high, although relatively lower compared to the highest values reported in the literature for corn and rice extrudates. The UD values for all the extrudates ranged from 0.12 to 0.35 g/cm3 , WAI, and WSI values ranged from 10.98 to 12.10 g/g and from 0.12% to 7.73%, respectively. Both screw speed and moisture content had significant impacts on the ER (P less then 0.01). The highest ER was observed for the extrusion cooking conditions of the lowest moisture content level (15%), lowest barrel temperature (120 °C), and lowest screw speed (150 rpm). The cross-sectional microstructure of the extrudates showed that the samples with a high ER had thick and elongated pores. The results of this study indicate that pea starch is a viable ingredient for making puffed extruded products. PRACTICAL APPLICATION The food industry can utilize the information generated from this study in the development of extruded expanded food products with pea starch. The specific information related to process conditions can assist the food industry in determining the ideal conditions for extrusion cooking in the production.
  Current conventional therapeutic strategies for lumbosacral pain during pregnancy are usually inadequate and data regarding interventional analgesic procedures feasible in pregnant women is scarce. We decided to retrospectively review our experience of ultrasound-guided pain management procedures in pregnant women with lumbosacral pain unresponsive to conservative treatment.
 
  Twenty women in the second trimester of pregnancy with lumbosacral pain developed during pregnancy unresponsive to conservative treatments who underwent the following ultrasound-guided pain interventions were included sacroiliac joint, caudal epidural, interlaminar epidural, and trigger point injections. All patients were followed up until early postnatal period using Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores.
 
  All but one patient achieved satisfactory pain control throughout the pregnancy with a single injection. Significant declines in ODI and VAS scores was attained within the first 2 weeks and first week of intervention, respectively, which was maintained thereafter until early postnatal period.
 
  Injections used for effective interventional pain management in nonpregnant populations seem to represent an effective and safe method also for pregnant women when performed under ultrasound guidance, with rapid onset and enduring duration of action until the time of delivery.
