The inoculum effect (IE) is an increase in the minimum inhibitory concentration (MIC) of an antibiotic as a function of the initial size of a microbial population. The IE has been observed in a wide range of bacteria, implying that antibiotic efficacy may depend on population density. Such density dependence could have dramatic effects on bacterial population dynamics and potential treatment strategies, but explicit measures of per capita growth as a function of density are generally not available. Instead, the IE measures MIC as a function of initial population size, and population density changes by many orders of magnitude on the timescale of the experiment...

In this study, composite calcium-alginate/carbon nanotubes/TiO2 beads were prepared and tested for their potential in the removal of bisphenol A (BPA) from aqueous solutions. The removal traits were inspected using a fixed-bed sorption column. By varying parameters such as bed height (15-20 cm), flow rate (2.0-6.0 mL.min(-1)) and inlet BPA concentration (10-30 mg.L(-1)) we assessed the removal capacity of these composites. The highest sorption capacity of 5.46 mg.g(-1) was achieved at 10 mg.L(-1) BPA concentration, 2...

BACKGROUND AND PURPOSE: When fractionation schemes for hypofractionation and stereotactic body radiotherapy are considered, a reliable cell survival model at high dose is needed for calculating doses of similar biological effectiveness. An alternative to the LQ-model is the track-event theory which is based on the probabilities for one- and two two-track events. A one-track-event (OTE) is always represented by at least two simultaneous double strand breaks. A two-track-event (TTE) results in one double strand break...

: The fixed dose combination of sitagliptin 50 mg and metformin 850 mg (Janumet ®), is indicated for the treatment of type 2 diabetes mellitus in addition to diet and exercise to improve glycemic control in patients treated with metformin alone. METHODS: We report a 69-year-old man with type 2 diabetes that developed sudden loss of eyebrows and eyelashes about 4 months after the beginning of Janumet ®. Clinical and laboratory findings excluded the presence of systemic or skin diseases able to induce these manifestations, while the Naranjo probability scale documented a possible association between the drug and the adverse drug reaction...

The fixed-dose combination adapalene 0.1%/benzoylperoxide 2.5% (A/BPO) was introduced as an acne vulgaris therapeutic in 2007. It combines anti-inflammatory, keratolytic, comedolytic, and antibacterial properties. Thus, it addresses several pathophysiological factors involved in the pathophysiology of acne. This review highlights the rationale for the use of this fixed-dose combination product, its therapeutic efficacy including effects on adherence and quality of life, its use for different forms of acne, and the side-effect profile...

The dramatic rise in the prevalence of obesity and diabetes is associated with increased morbidity, mortality, and public health care costs worldwide. The need for new, effective, and long-lasting drugs is urgent. Recent research has focused on the role of the inhibitors of sodium- glucose co-transporter 2 (SGLT-2). Clinical trials have shown that SGLT-2 inhibitors have glycemic efficacy and weight-lowering potential. Dual drug therapy is a recommended therapy for patients with new-onset type 2 diabetes who need significant glycemic control...

Currently available therapies for the treatment of Alzheimer's disease (AD) consist of cholinesterase inhibitors (ChEIs), such as donepezil, and the N-methyl-D-aspartate receptor antagonist memantine. In December 2014, the US Food and Drug Administration approved Namzaric™, a once-daily, fixed-dose combination (FDC) of memantine extended-release (ER) and donepezil for patients with moderate-to-severe AD. The FDC capsule is bioequivalent to the coadministered individual drugs, and its bioavailability is similar when taken fasting, with food, or sprinkled onto applesauce...

BACKGROUND: Hydroxyurea (HU) has been demonstrated to be efficacious in reducing complications in individuals with sickle cell anemia (SCA) but poor adherence is a barrier. Directly Observed Therapy (DOT) has been shown to improve adherence in various chronic diseases but there is limited data in adults with SCA. METHODS AND DESIGN: To examine the effect of mobile-directly observed therapy (mDOT) on adherence to HU (mDOT-HuA) in adults with SCA at Muhimbili National Hospital in Tanzania...

BACKGROUND: Most studies that have compared programmed intermittent epidural bolus (PIEB) with continuous epidural infusion regimens have included patient-controlled epidural analgesia and/or manual bolus as rescue analgesia for breakthrough pain. Consequently, the optimal time interval between PIEB is yet to be determined. We designed a study to establish the optimal time interval between PIEB of 10 mL of bupivacaine 0.0625% with fentanyl 2 μg/mL to produce effective analgesia in 90% of women during first stage of labor without breakthrough pain...

Among individuals with established CVD, multiple medications (aspirin, blood pressure lowering drugs and statins) are required to manage CVD and it is well established that non adherence to prescribed treatments is substantial in the long term. Such discontinuation of CV-preventive medications and low adherence rates has been shown to affect the success of CVD prevention efforts. In low- and middle income countries only less than 20% patients receive recommended therapy for CVD prevention, but even in high-income countries treatment coverage in the community is only about 50% in those with heart disease and 35% in those with stroke...

Background: Osteoporosis is a chronic disease and adherence can fluctuate over time. Therefore, longer observation is necessary to investigate the stability of patients' adherence. The study aim was to compare the overall adherence (OA) to supplementation with the fixed combination of calcium and vitamin D (Ca/D) in postmenopausal women at baseline and after 1 year, and to evaluate the fluctuation of the OA in individual months. Furthermore, we studied whether adherence is influenced by signing of informed consent and routine medical check-up...

BACKGROUND/AIMS: Hesperidin pretreatment has been shown to protect against myocardial ischemia/reperfusion (I/R) injury, but the underlying mechanism is poorly understood. This study aimed to investigate the cardioprotective effects of a 3-day hesperidin pretreatment on I/R injury and to further explore whether its mechanism of action was associated with the inhibition of high mobility group box 1 protein (HMGB1) expression via the PI3K/Akt pathway. METHODS: In a fixed-dose study, hematoxylin and eosin staining and myocardial enzyme measurements were used to determine the optimal dose of hesperidin that elicited the best cardioprotective effects against I/R injury...
