PURPOSE: The objective of this study was to evaluate the exposure and the pharmacodynamic target attainment of piperacillin/tazobactam (PTZ) in adult critically ill patients.
METHODS: We conducted a prospective observational study in the intensive care unit (ICU) of the Hôpital du Sacré-Cœur de Montréal (a Level I trauma centre in Montreal, QC, Canada) between January 2021 and June 2022. We included patients aged 18 yr or older admitted to the ICU who received PTZ by intravenous administration. Demographic and clinical characteristics were collected, and clinical scores were calculated. On study day 1 of antimicrobial therapy, three blood samples were collected at the following timepoints: one hour after PTZ dose administration and at the middle and at the end of the dosing interval. The sampling schedule was repeated on days 4 and 7 of therapy if possible. Samples were analyzed by ultra-high performance liquid chromatography with diode array detector to determine the total piperacillin concentration. Middle- and end-of-interval concentrations were used for target attainment analyses, and were defined as a concentration above the minimal inhibitory concentration of 16 mg·L-1, corresponding to the breakpoint of Enterobacteriaceae and Pseudomonas aeruginosa.
RESULTS: Forty-three patients were recruited and 202 blood samples were analyzed. The most prevalent dose was 3/0.375 g every six hours (n = 50/73 doses administered, 68%) with a 30-min infusion. We observed marked variability over the three sampling timepoints, and the median [interquartile range] piperacillin concentrations at peak, middle of interval, and end of interval were 109.4 [74.0-152.3], 59.3 [21.1-74.4], and 25.3 [6.8-44.6] mg·L-1, respectively. When assessing target attainment, 37% of patients did not reach the efficacy target of a trough concentration of 16 mg·L-1. The majority of patients who were underexposed were patients with normal to augmented renal clearance.
CONCLUSION: In this prospective observational study of adult ICU patients receiving intravenous PTZ, a large proportion had subtherapeutic concentrations of piperacillin. This was most notable in patients with normal to augmented renal clearance. More aggressive dosage regimens may be required for this subpopulation to ensure attainment of efficacy targets.
AIM: Febrile urinary tract infection is a common bacterial infection in childhood. The kidney damage after acute pyelonephritis (APN) could be related to the stimulation of the proinflammatory response. We aimed to investigate the role of inflammatory cytokines and the effect of dexamethasone after a first episode of APN.
METHODS: Subanalysis of the DEXCAR RCT in which children with confirmed APN (1 month-14 years) were randomly assigned to receive a 3 days course of either intravenous dexamethasone or placebo. Urinary cytokine levels at diagnosis and after 72 h of treatment were measured.
RESULTS: Ninety-two patients were recruited. Younger patients, males and those with abnormalities in the ultrasound study or vesicoureteral reflux showed higher values of urinary cytokines. Patients with severe APN had higher Tumour Necrosis Factor (TNF)α levels (81.0 ± 75.8 vs. 33.6 ± 48.5 pg/mg creatinine, p = 0.015). Both intervention groups showed similar basal clinical characteristics, including urinary cytokine levels. Treatment reduced urinary cytokine levels irrespective of dexamethasone administration. Neither the intervention group nor the urinary cytokine levels modulated the development of kidney scars.
CONCLUSION: Basal urinary cytokines were associated with age, abnormal ultrasound and vesicoureteral reflux. Patients with severe APN had higher TNFa urinary levels. Administration of dexamethasone in children with APN does not improve the control of the proinflammatory cytokine cascade.

Paraplegic patients who admitt to our Physical Therapy and Rehabilitation Clinic, will be included in the rehabilitation program. Sixty spinal cord injured patients with serum 25 (OH) D3 levels less than 20 ng / ml will be included in the study. One of the treatment groups will receive 6,000 IU of vitamin D daily, and the other group 50,000 IU of vitamin D per week for eight weeks. Patients with high calcium (Ca) values in blood tests, patients with kidney stones and urinary stones in urinary ultrasonography (USG) to be performed routinely, as well as patients who refuse to use vitamin D supplements will include in the control group. Spinal cord independence measure (SCIM version 3) will be filled in at the beginning and at the end of 8 weeks to all participants. Jamar Dynamometer will be measured for upper extremity muscle strength, and biceps brachii and triceps muscle thicknesses will be measured by ultrasonography.

The stretching exercise with the Foam roller will be done during 2 minutes in each member.
Physostigmine Salicylate Injection is a reversible anticholinesterase which effectively increases the concentration of acetylcholine at the sites of cholinergic transmission. The action of acetylcholine is normally very transient because of its hydrolysis by the enzyme, acetylcholinesterase. Physostigmine Salicylate Injection inhibits the destructive action of acetylcholinesterase and thereby prolongs and exaggerates the effect of the acetylcholine.

Physostigmine Salicylate Injection contains a tertiary amine and easily penetrates the blood brain barrier, while an anticholinesterase, such as neostigmine, which has a quaternary ammonium ion is not capable of crossing the barrier. Physostigmine Salicylate Injection can reverse both central and peripheral anticholinergia. The anticholinergic syndrome has both central and peripheral signs and symptoms. Central toxic effects include anxiety, delirium, disorientation, hallucinations, hyperactivity and seizures. Severe poisoning may produce coma, medullary paralysis and death. Peripheral toxicity is characterized by tachycardia, hyperpyrexia, mydriasis, vasodilation, urinary retention, diminution of gastrointestinal motility, decrease of secretion in salivary and sweat glands, and loss of secretions in the pharynx, bronchi, and nasal passages.

Dramatic reversal of the effects of anticholinergic symptoms can be expected in minutes after the intravenous administration of Physostigmine Salicylate Injection, if the diagnosis is correct and the patient has not suffered anoxia or other insult. The duration of action of Physostigmine Salicylate Injection is relatively short, approximately 45 to 60 minutes.

Numerous drugs and some plants produce the anticholinergic syndrome either directly or as a side effect; this undesirable or potentially dangerous phenomenon may be brought about by either therapeutic doses or overdoses of the drugs. Such drugs include among others, atropine, other derivatives of the belladonna alkaloids, tricyclic antidepressants, phenothiazines, and antihistamines.

Obesity is characterized by excessive accumulation of adipose tissue (mainly visceral). The morphology and function of mitochondria are crucial for regulating adipose browning and weight loss. Research suggests that the SGLT2 inhibitor canagliflozin may induce weight loss through an unknown mechanism, particularly targeting visceral adipose tissue. While Krueppel-Like Factor 4 (KLF4) is known to be essential for energy metabolism and mitochondrial function, its specific impact on visceral adipose tissue remains unclear. We administered canagliflozin to db/db mice for 8 weeks, or exposed adipocytes to canagliflozin for 24 h. The expression levels of browning markers, mitochondrial dynamics, and KLF4 were assessed. Then we validated the function of KLF4 through overexpression in vivo and in vitro. Adenosine monophosphate-activated protein kinase (AMPK) agonists, inhibitors, and KLF4 si-RNA were employed to elucidate the relationship between AMPK and KLF4. The findings demonstrated that canagliflozin significantly decreased body weight in db/db mice and augmented cold-induced thermogenesis. Additionally, canagliflozin increased the expression of mitochondrial fusion-related factors while reducing the levels of fission markers in epididymal white adipose tissue. These consistent findings were mirrored in canagliflozin-treated adipocytes. Similarly, overexpression of KLF4 in both adipocytes and db/db mice yielded comparable results. In all, canagliflozin mitigates obesity in db/db mice by promoting the brown visceral adipocyte phenotype through enhanced mitochondrial fusion via AMPK/KLF4 signaling.
Sepsis-associated lung injury often coexists with intestinal dysfunction. Butyrate, an essential gut microbiota metabolite, participates in gut-lung crosstalk and has immunoregulatory effects. This study aims to investigate the effect and mechanism of sodium butyrate (NaB) on lung injury. Sepsis-associated lung injury was established in mice by cecal ligation and puncture (CLP). Mice in treatment groups received NaB gavage after surgery. The survival rate, the oxygenation index and the lung wet-to-dry weight (W/D) ratio were calculated respectively. Pulmonary and intestinal histologic changes were observed. The total protein concentration in bronchoalveolar lavage fluid (BALF) was measured, and inflammatory factors in serum and BALF were examined. Diamine oxidase (DAO), lipopolysaccharide (LPS), and surfactant-associated protein D (SP-D) levels in serum and amphiregulin in lung tissue were assessed. Intercellular junction protein expression in the lung and intestinal tissues were examined. Changes in immune cells were analyzed. NaB treatment improved the survival rate, the oxygenation index and the histologic changes. NaB decreased the W/D ratio, total protein concentration, and the levels of proinflammatory cytokines, as well as SP-D, DAO and LPS, while increased the levels of anti-inflammatory cytokines and amphiregulin. The intercellular junction protein expression were improved by NaB. Furthermore, the CD4+/CD8+ T-cell ratio and the proportion of CD4+Foxp3+ regulatory T cells (Tregs) were increased by NaB. Our data suggested that NaB gavage effectively improved the survival rate and mitigated lung injury in CLP mice. The possible mechanism was that NaB augmented CD4+Foxp3+ Tregs and enhanced the barrier function of the gut and the lung.
For safety reasons, study subjects under regional anesthesia will automatically be assigned to this group and will receive a fixed dose of 5000 units of heparin administered intravenously 2 minutes prior to vascular clamping and blood flow interruption. A subsequent dose of heparin will be administered if requested by the surgeon following a visual assessment of the anticoagulation in the surgical field. Anticoagulation will be monitored at different time points during surgery using ACT and TEG.
This study was designed to investigate the potential of extracellular adenosine 5'-triphosphate (ATP) via the P2 X 7 receptor to activate the renal fibrotic processes in rats. The present study demonstrates that administration of ATP rapidly activated transforming growth factor-β (TGF-β) to induce phosphorylation of Smad-2/3. Renal connective tissue growth factor (CTGF) and tissue inhibitor of metalloproteinase-1 (TIMP-1) mRNA and protein expressions were also increased following ATP administration. A decrease in TGF-β amount in serum as well as renal Smad-2/3 phosphorylation was noticed in animals pre-treated with the specific antagonist of P2 X 7 receptor, A 438,079. In addition, a significant reduction in mRNA and protein expression of CTGF and TIMP-1were also observed in the kidneys of those animals. Collectively, the current findings demonstrate that ATP has the ability to augment TGF-β-mediated Smad-2/3 phosphorylation and enhance the expression of the pro-fibrotic genes, CTGF and TIMP-1, an effect that is largely mediated via P2 X 7 receptor.
An on-line filtration system for the removal of macromolecules greater than 70,000 mol. wt. from a physiological solution, such as blood, in the therapeutic treatment of various disease states. For blood, the plasma (which contains the macromolecules) is separated continuously from the blood using a first membrane filter with a membrane porosity of nominally 0.2 to 1.0 micron. The separated plasma is then continuously filtered in a physiological temperature state or a cooled state through a second membrane filter with a membrane porosity of nominally 0.01 to 0.2 micron, which retains the macromolecules. In the cooled state, separation of the macromolecules is effected more efficiently than could be done in the non-cooled state. The treated plasma (macromolecules removed) is then reunited with the blood flow coming from the first plasma filter and returned to the patient. The blood flow and filtration processes are generally continuous. Suitable agent(s) may be added to the separated plasma to promote formation of macromolecules.
BACKGROUND: Human epidermal growth factor receptor 2 (HER2)-positive breast cancer accounts for about 20% of all breast cancer cases and is correlated with a high relapse rate and poor prognosis. ADAMTS18 is proposed as an important functional tumor suppressor gene involved in multiple malignancies, including breast cancer. It functions as an extracellular matrix (ECM) modifier. However, it remains unclear whether ADAMTS18 affects mammary tumorigenesis and malignant progression through its essential ECM regulatory function.
METHODS: To elucidate the role of ADAMTS18 in HER2-positive mammary tumorigenesis and metastasis in vivo, we compared the incidence of mammary tumor and metastasis between Adamts18-knockout (MMTV)-Her2/ErbB2/Neu+ transgenic mice (i.e., Her2t/w/Adamts18-/-) and Adamts18-wildtype (MMTV)-Her2/ErbB2/Neu+ transgenic mice (i.e., Her2t/w/Adamts18+/+). The underlying mechanisms by which ADAMTS18 regulates HER2-positive tumorigenesis and metastasis were investigated by pathology, cell culture, Western blot and immunochemistry.
RESULTS: Adamts18 mRNA is mainly expressed in myoepithelial cells of the mammary duct. ADAMTS18 deficiency leads to a significantly increased incidence of mammary tumors and metastasis, as well as mammary hyperplasia in mice, over 30 months of observation. The proliferation, migration and invasion capacities of primary Her2t/w/Adamts18-/- mammary tumor cells are significantly higher than those of primary Her2t/w/Adamts18+/+ mammary tumor cells in vitro. At 30 months of age, the expression levels of laminin (LNα5), fibronectin (FN) and type I collagen (ColI) in the mammary glands of Her2t/w/Adamts18-/- mice are significantly increased, and the activities of integrin-mediated PI3K/AKT, ERK and JNK signaling pathways are enhanced.
CONCLUSIONS: ADAMTS18 deficiency leads to alterations in mammary ECM components (e.g., LNα5, FN, ColI), which are associated with a higher risk of HER2-positive mammary tumorigenesis and metastasis.
Ovarian stimulation will be performed using a fixed antagonist protocol with Follitropin Alfa (daily in the evening) and Ganirelix/Cetrorelix (daily in the morning). Selection of the daily gonadotropin dose will be based on ovarian reserve parameters (AMH and AFC) and BMI. Co-administration of 5 mg of letrozole daily (in the morning) commencing on the first day of gonadotropin administration and continuing throughout the ovarian stimulation will be performed as this reduces oestradiol concentrations. GnRH agonist Triptorelin 0.2 mg Daily form will be used for final oocyte maturation. Hormone analysis, analysis of haematology and biochemistry and a pelvic ultrasound scan will be done on days 3, 5 and 7 after oocyte retrieval. The first administration of Triptorelin 3.75mg depot will be scheduled on the first day of the menstrual cycle after oocyte retrieval. To prevent the flare-up produced by the GnRH agonist, daily doses of 0.25mg of Ganirelix/Cetrorelix will be given for seven days.
<P>PROBLEM TO BE SOLVED: To obtain an intestinal microorganism capable of decomposing hormone disruptive substance or carcinogenic substance such as bisphenol A, dioxins, and the utilization of the same strain as a probiotics food product or an environmental restoring agent.  <P>SOLUTION: The method for obtaining the intestinal microorganism comprises adding an intestinal specimen of a healthy human being such as feces (or a lactobacillus strain bank) to an inorganic nutrition medium by using the above undesirable compound or its structural analog as a sole carbon source, isolating a bacterial strain by accumulative culturing to obtain a new strain belonging to the genus Achromobacter (Achromobacter sp. Shibata-9 strain: FERM P-18873) capable of decomposing bisphenol A. The strain obtained by the accumulative culturing is used as the probiotics food product by adding it into a yogurt, or the like, or as an oral agent by using an enteric capsule, or the like, or a suppository for trying to reduce the hormone disruptive substance or carcinogenic substance in the living body after the recognition of its safety, or as the environmental restoring agent (in sewage treatment, or the like). The intestinal bacterial strain can be utilized for both of the probiotics and environmental cleaning.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
Assays for identifying compounds which modulate signalling via PD-1 are disclosed. The assays are based on the discovery that PD-1 is a receptor for B7-4 molecules expressed on antigen presenting cells. PD-I transmits a negative signal to immune cells, similar to CTLA4. B7-4 molecules are expressed on the surface of antigen presenting cells and provide a costimulatory signal to immune cells and can transmit downmodulatory signals to immune cells, depending upon the molecule to which they bind. Thus, modulation of PD-1, B7-4, and/or the interaction between B7-4 and PD-1 results in modulation of the immune response. Also described is a method for modulating an immune response comprising contacting an immune cell with an agent that modulates signalling via PD-1 to thereby modulate the immune response. The immune cell may be, for instance, a T cell, a B cell, or a myeloid cell.
Surveys used to conduct this study will be administered via telephone or online by InfoMedics, Inc., a company with a system for developing such patient-physician feedback programs. Participating physicians will ask their patients to participate in the program after Metanx® has been prescribed and provide them with a brochure containing an introduction to the program and instructions on how to enroll. Patients self-enroll, take a brief survey before starting their Metanx® prescription, and then two brief follow-up surveys at 6 weeks and 12 weeks. As patients complete surveys within the study, their physician will receive individualized feedback reports outlining their patient's treatment experience and progress. Patients will also receive a copy of their own reports, to help encourage them to continue taking Metanx® as directed. Patients will also receive educational materials about managing their diabetic neuropathy.
The same planning and treatment procedures will be performed. The total dose will be 4500 cGy in 15 fractions in 3 weeks; giving 300 cGy per fraction.
The present invention provides a heat-stable nuclease found in Y. enterocolitica subsp. palearctica that is active in broad spectrum conditions. Using the genome sequences of Y. enterocolitica subsp. enterocolitica, we identified one nuclease named Nucyep. This gene was sequenced in a strain Y. enterocolitica subsp. palearctica, cloned, and expressed in E. coli, and then purified and characterized. The molecular weight of this enzyme is about 30 to 32 kDa. The translation product, a nuclease referred to as "Nucyep" is biologically active. The purified Nucyep1 exhibits non-specific nuclease activity, being able to degrade various nucleic acids, including RNA, single-stranded DNA (ssDNA) and linear or circular double-stranded DNA (dsDNA). This enzyme is active in a wide range of temperatures, from 0 to 100°C. The enzyme is active in a wide range of pH values from 3.6 to 9.9, and keeps greater than 75% of the activity at pH 7.24. This enterobacterial nuclease has unique levels of intrinsic resistance to heat, and is active under a large spectrum of conditions.
