Today, ISOpg of peginterferon-a2a once weekly for 48 weeks is recommended in patients with compensated liver disease. However, treatment schedules mat were chosen in clinical trials vary between 24 weeks to 2 years and optimal treatment durations and dose remain to be defined. 

Unfortunately, many clinical studies evaluating the efficacy of dietary supplements are flawed. Some of the flaws in the studies include non-randomization, being unblinded, lack of standardized products, small sample sizes, short treatment durations, and poorly defined inclusion and exclusion criteria. Many studies do not give detailed information about the dietary supplement used. When an herb is studied, the following information should be described plant species, part(s) used, product form (e.g., powdered crude herb, aqueous extract, ethanol extract, or aqueous alcohol extract) with stated proportions of water to alcohol, specifically extracted fractions, and quantities or concentrations used [48]. 

With symptom-triggered therapy, medication is given only if symptoms emerge, resulting in shorter treatment duration, and avoidance of over sedation. A typical regimen would be lorazepam 2 mg administered every hour as needed when a structured assessment scale (e.g., Clinical Institute Withdrawal Assessment-Alcohol, Revised) indicates that symptoms are moderate to severe. Current guidelines recommend such individualized therapy over fixed-schedule therapy. 

The efficacy of the antigen retrieval procedure also depends on the treatment duration and the cooling conditions (see Subheadings 3.1.-3.5.), The power of the heating device and the buffer volume are among the major factors that determine the duration of a particular HIER protocol. 

For a further decomposition, see Pomerantz et al. (2004), who hnd that patients seen by psychiatrists were most likely to receive appropriate treatment duration, patients seen by primary care and internal medicine physicians were less likely to receive appropriate treatment duration, and patients seen by specialists other than psychiatrists, primary care physicians, or internists were least Hkely to receive appropriate treatment duration.

Identification of patients who would not have otherwise qualified by virtue of a novel test, as has been the case for the use of imatinib in gastrointestinal stromal tumors that express a mutated KIT receptor, and increased treatment duration and compliance linked to prolongation of survival or efficacy in the adjuvant setting. In the final analysis, a significant clinical benefit can be expected to lead to higher adoption rates. 

Two carcinogenicity bioassays were conducted in rats (3-60x MRHD). Treatment resulted in a marked dose-related increase in the incidence of osteosarcoma, a rare mahgnant bone tumor, in both male and female rats. Osteosarcomas were observed at all doses and the incidence reached 40-50% in the high-dose groups. Teriparatide also caused a dose-related increase in osteoblastoma and osteoma in both sexes. Bone tumors in rats occurred in association with a large increase in bone mass and focal osteoblast hyperplasia Second 2-year study was carried out in order to determine the effect of treatment duration and animal age on the development of bone tumors. Female rats were treated for different periods between 2 and 26 months of age (at 3x to 20x MRHD based on body surface area). The... 

The current label for PTH(l-34), the first approved PTH analogue, reports dose-related increase in osteosarcomas, osteoblastomas, and osteomas in two-rat carcinogenicity studies as well as results from a second two-year study in rats designed to determine the effect of treatment duration and animal... 

In a prospective, multicenter, cohort study of 113 patients with aplastic anemia under 18 years of age, 12 developed myelodysplastic syndrome after a median of 37 months after the diagnosis of aplastic anemia and four others developed other cytogenetic clonal changes, of which the most common abnormality was monosomy 7 (80). From a multivariate analysis, G-CSF treatment duration and non-response to immunosuppressive therapy at 6 months were statistically significant risk factors for the development of myelodysplastic syndrome. The... 

Numerous oral carcinogenicity studies of NDMA of intermediate duration have been conducted. Treatment durations were often in the range of 20-40 weeks, frequency of treatment ranged from once weekly to daily, and carcinogenicity was observed in all studies. Studies representing various treatment durations and various methods of oral treatment (drinking water, diet and gavage) for the lowest doses in different species are identified below. 

Kan (2007a) examined the effect of treatment duration and pressure of low-temperature plasma treatment on the antistatic property of polyester fabric. The results show that when the treatment duration increases, the half-life decay time decreases accordingly, which means that the antistatic property is improved with a longer treatment duration. When a longer treatment duration is used, more interaction occurs between the fiber surface and the plasma species. As a result, the alteration on the fiber surface becomes more pronounced.
