Background: Normal saline solution (NSS) has been the fluid of choice for renal transplant patients, but it can lead to hyperchloremic acidosis and hyperkalemia. This study was performed to compare the safety profile of low-chloride solutions with that of NSS in renal transplant patients. Methods: We conducted a systemic review search on PubMed, Embase, and the Central Cochrane Registry. Randomized clinical tri-als (RCTs) and matched cohort studies involving NSS as the control arm and low-chloride solutions as an intervention arm were cho-sen. The standardized mean difference for continuous variables, the odds ratio (OR) for discrete variables, and a 95% confidence in-terval (CI) for effect sizes were used. A p-value of <0.05 was considered statistically significant. Analysis was performed using a ran-dom-effects model irrespective of heterogeneity, which was evaluated using I<sup>2</sup> statistics. Results: Nine RCTs and one cohort study with a total of 726 patients were included. After transplantation, serum potassium was sig-nificantly lower in the low-chloride group (standardized mean difference compared to NSS group, -0.38 mEq/L; 95% CI, -0.66 to -0.11; p = 0.007). Similarly, postoperative chloride was lower in the low-chloride group (-2.41 mEq/L [-3.34 to -1.48], p < 0.001). No statistically significance was observed in delayed graft function (OR, 0.98 [0.56-1.69], p = 0.93), day 3 creatinine (-0.14 mg/dL [-0.46 to 0.18], p = 0.38), or day 7 urine output (-0.08 L [-0.29 to 0.12], p = 0.43). onclusion: Use of NSS during renal transplant leads to increased incidence of hyperchloremic acidosis with subsequent hyperkale-mia, but clinical significance in the form of delayed graft function or postoperative creatinine remains comparable to that of low-chlo-ride solutions.

Background: Antimicrobial resistance is on the rise. The use of redundant and inappropriate antibiotics is contributing to recurrent infections and resistance. Newer antibiotics with more robust coverage for Gram-negative bacteria are in great demand for complicated urinary tract infections (cUTIs), complicated intra-abdominal infections (cIAIs), hospital-acquired bacterial pneumonia (HABP), and ventilator-associated bacterial pneumonia (VABP). Materials and Methods: We performed this meta-analysis to evaluate the efficacy and safety profile of a new antibiotic, Imipenem/cilastatin/relebactam, compared to other broad-spectrum antibiotics for complicated infections. We conducted a systemic review search on PubMed, Embase, and Central Cochrane Registry. We included randomized clinical trials-with the standard of care as comparator arm with Imipenem/cilastatin/relebactam as intervention arm. For continuous variables, the mean difference was used. For discrete variables, we used the odds ratio. For effect sizes, we used a confidence interval of 95%. A P-value of less than 0.05 was used for statistical significance. Analysis was done using a random-effects model irrespective of heterogeneity. Heterogeneity was evaluated using the I2 statistic. Results: The authors observed similar efficacy at clinical and microbiologic response levels on early follow-up and late follow-up compared to the established standard of care. The incidence of drug-related adverse events, serious adverse events, and drug discontinuation due to adverse events were comparable across both groups. Conclusion: Imipenem/cilastatin/relebactam has a non-inferior safety and efficacy profile compared to peer antibiotics to treat severe bacterial infections (cUTIs, cIAIs, HABP, VABP).

Metabolites of Marine Algae Collected from Karachi-coasts of Arabian Sea
Muhammad Shaiq Ali,Muhammad Jahangir,Muhammad Saleem,Muhammad Kashif Pervez,Shaista Hameed,Viqar Uddin Ahmad 한국생약학회 2000 Natural Product Sciences Vol.6 No.2
The ethanolic extracts of marine green, brown and red algae collected from Karachi coasts of Arabian Sea afforded a new enol-derivative of N-acylsphingosine named as coelarthenol (1) from Coelarthrum muelleri, two new glucose-derivatives named: botryenal (2) and botryenol (3) from Botryocladia leptopoda, α-tocopherol quinone (4) from Codium iyengarii, β-sitosterol and hexadecanoic acid from Stokeyia indica. The known constituents (4, β-sitosterol & hexadecanoic acid) have not been reported so far from their corresponding sources and the structures were determined through spectroscopic methods, whereas, the structures of new constituents (1-3) were elucidated with the aid of selective HMBC experiments. The phytotoxicity of 4 was also monitored.

Evolvulus alsinoides: A potential antihypertensive herb
Siraj, Mantasha Binth,Khan, Asim Ali,Jahangir, Umar,Hashimi, Ayshah,Ahmad, Yasmeen Cellmed Orthocellular Medicine and Pharmaceutical 2019 셀메드 (CellMed) Vol.9 No.4
In spite of the fact that a variety of unfailing guidelines are existing for the management of hypertension, the problem of inadequate managing of this condition still continues. Several classes of existing antihypertensive drugs are associated with various side-effects. Since ancient times before the advent of anti-hypertensive drugs, this disease has been treated by the prominent classical scholars. Various herbal drugs are being used since ages for the treatment of hypertension and some of them are validated too. Evolvulus alsinoides is also one such herb used in classical literature since ages for various disorders like insanity, anxiety, nervous debility, epilepsy, melancholy, palpitation and many others. This review is to highlight the antihypertensive potential of Evolvulus alsinoides.
