The consumption of extra virgin olive oil (EVOO) is common in the Mediterranean Diet, which is largely known to have several health benefits and to increase longevity, as reported by the United Nations Educational Scientific and Cultural Organization (UNESCO) in 2010 [8,9]. As recently reported in the III International Conference on Virgin Olive Oil and Health Consensus Report, EVOO intake is also associated with reduced risk of most ageing-related diseases including cardiovascular and neurodegenerative diseases (CVD and NDD), and some types of cancer [10]. Initially, the beneficial properties of EVOO were attributed to functional components such as monounsaturated and polyunsaturated fatty acids (MUFAs and PUFAs), like oleic acid (55 to 83% of total fatty acid (FA)), the essential FA, linoleic acid (3 to 21% of total FA), and linolenic acid (0 to 1.5% of total FA). However, recent epidemiological and experimental studies also show that minor bioactive compounds, including phenolic alcohols, such as hydroxytyrosol (HT, 3,4-dihydroxyphenylethanol, 3,4-DHPEA) and tyrosol (p-hydroxyphenylethanol, p-HPEA), secoiridoid derivatives, phenolic acids, lignans, and flavonoids contribute to the beneficial effects of EVOO [11,12,13]. A high biophenol content confers a high stability to EVOOs, preventing EVOO autoxidation and contributing to a long shelf-life.
Ole belongs to the secoiridoids, which are abundant in Oleaceas, Gentianales Cornales, as well as many other plants. Iridoids and secoiridoids are compounds that are usually glycosidically bound, and are produced from the secondary metabolism of terpenes, as precursors of various indole alkaloids. The secoiridoids in Oleaceae are usually derived from the oleoside type of glucosides (oleosides), which are characterized by an exocyclic 8,9-olefinic functionality, a combination of elenolic acid and a glucosidic residue [16]. Ole is an ester of elenolic acid and HT, and has a oleosidic skeleton that is common to the secoiridoid glucosides of Oleaceae (Figure 1)
More-recently, Momtaz et al. [149] has shown the influence of Ole on melanoma. Melanoma is certainly one of the most aggressive skin cancers, due to its progression to drug resistance and its organ dissemination. Among the signalling pathways able to control melanoma development, janus kinase signal transducers and activators of transcription (JAKs/STATs) are the most critical, and polyphenols are able to target the most active, STAT3.
Starting from the epidemiological observation that obesity is associated with an increased risk of developing many cancers, and metastatic dissemination represents the leading cause of mortality of cancer patients, a study by Song et al. [155] suggests that Ole inhibits tumor growth and lymph node metastasis in mouse melanoma cells, abrogating angiogenesis and lymphangiogenesis through the reduction of the peroxisome proliferator-activated receptor γ and the infiltration of M2 macrophages, both responsible for the secretion of angiogenesis and lymphangiogenesis inducers, VEGFA and D, respectively.
The risks and benefits of different screening tests vary. See Table 1 for characteristics of recommended screening strategies, which may include combinations of screening tests. Because of limited available evidence,9,10 the USPSTF recommendation does not include serum tests, urine tests, or capsule endoscopy for colorectal cancer screening. Recommended stool-based and direct visualization screening tests are described below.
Two prospective cohort studies (n=436,927) in US-based populations reported on colorectal cancer outcomes after colonoscopy screening.9,10 One study among health professionals found that after 22 years of follow-up, colorectal mortality was lower in persons who reported receiving at least 1 colonoscopy (adjusted hazard ratio, 0.32 [95% CI, 0.24-0.45]),39 although findings were no longer significant after 5 years for adults with a first-degree relative with colorectal cancer. This study included persons younger than 50 years, although results for this age group were not reported separately. Another cohort study among Medicare beneficiaries reported that the risk of colorectal cancer was significantly lower in adults aged 70 to 74 years (but not aged 75 to 79 years) 8 years after receiving a screening colonoscopy (standardized risk, 0.42% [95% CI, 0.24%-0.63%]).40 One large, prospective cohort study (n=5,417,699) from Taiwan reported on colorectal cancer mortality after introduction of a nationwide screening program with FIT in adults aged 50 to 69 years.41 After 1 to 3 rounds of biennial FIT screening, lower colorectal cancer mortality was found at 6 years of follow-up (adjusted relative risk, 0.90 [95% CI, 0.84-0.95]).
Harms from CT colonography are uncommon (19 studies; n=90,133), and the reported radiation dose for CT colonography ranges from 0.8 to 5.3 mSv (compared with an average annual background radiation dose of 3.0 mSv per person in the US).9,10 Accurate estimates of rates of serious harms from colonoscopy following abnormal CT colonography results are not available. Extracolonic findings on CT colonography are common. Based on 27 studies that included 48,235 participants, 1.3% to 11.4% of examinations identified extracolonic findings that required workup.9,10 Three percent or less of individuals with extracolonic findings required definitive medical or surgical treatment for an incidental finding. A few studies suggest that extracolonic findings may be more common in older age groups. Long-term clinical follow-up of extracolonic findings was reported in few studies, making it difficult to know whether it represents a benefit or harm of CT colonography.

On this site, the term "country" does not in all cases refer to a territorial entity that is a state as understood by international law and practice. As used here, the term also covers some territorial entities that are not states. Dependent territories of member countries are listed alphabetically followed by a description of the constitutional relationships with their member countries.
Afghanistan is currently going through a severe third wave of infections, with the number of cases and deaths topping the peaks of the first wave a year ago. Almost a third of the individuals tested recently had the infection. In response, the authorities have closed schools until further notice and are trying to speed up vaccinations. In consultation with the neighboring countries, they have also halted the movement of people across borders while keeping them open to trade and cargo transit.
The authorities aim to vaccinate 60 percent of the population. Essential workers and groups prioritized by the National Technical Committee based on their vulnerability to COVID-19 will be vaccinated first. Inoculations using 500,000 doses of the AstraZeneca vaccine donated by India started in February. The COVAX facility aims to provide vaccines covering 20 percent of the population, with the first shipments of 468,000 doses delivered in early March. Vaccination of another 28 percent of population is expected to be funded by World Bank and ADB grants. That said, less than one percent of the population has been fully vaccinated so far, and Afghanistan is facing a vaccine shortage after a large shipment has been delayed significantly. In response, China donated 700,000 doses, and the U.S. is delivering 3 million doses of the single-dose Johnson & Johnson COVID vaccine this week. In addition to the vaccine shortage, the inoculation campaign is also facing administrative challenges and vaccine hesitancy in rural areas.
The authorities rolled out about 0.8 percent of GDP social assistance under the World Bank-funded REACH program in 2020, with the remaining 0.6 percent of GDP continuing in 2021. The program targets Afghan households with incomes of $2 per day or lower (twice the national poverty line), with households in rural areas receiving an equivalent of $50 in essential food staples and hygiene products, while those in urban areas a combination of cash and in-kind equivalent to $100, in two tranches. .
The government adopted two support packages in 2020 for people and businesses affected by the COVID-19 pandemic of a combined size of Lek 45 billion (2.8 percent of GDP) consisting of budget spending, sovereign guarantees and tax deferrals. The first package adopted on March 19, 2020 through a normative act had support measures of Lek 23bn (1.4 percent of GDP) through a combination of spending reallocations, spending increases and sovereign guarantees to support affected businesses. The key measures are: (i) additional funding for health sector in the amount of Lek 2.5 billion (ii) Lek 6.5bn for the support of small businesses/self-employed that are forced to close activities due to the COVID-19 pandemic by paying them minimum salaries (up to two in the case of family businesses with unpaid family members), doubling of the unemployment benefits and social assistance layouts. (iii) Lek 2bn of defense spending reallocated toward humanitarian relief for the most vulnerable which were not used, (iv) Lek 11bn (0.6 percent of GDP) sovereign guarantee fund for companies to access overdrafts in the banking system to pay wages for their employees for up to 3 months with an interest rate capped at 2.85 percent for a maturity of up to 2 years. The government will bear the interest costs. The second package adopted on April 15 2020, includes (i) Lek 7bn (0.4 percent of GDP) fund to pay for a one-off transfer of Lk40,000 to employees of small businesses affected by the pandemic not covered in the first package, employees of large businesses laid off due to the pandemic, and employees in the tourism sector; (ii) a sovereign guarantee of Lek 15 billion (0.9 percent of GDP) to provide loans for working capital for all private companies that were tax-compliant and solvent before the pandemic. The government will guarantee 60 percent of the loans, and interest are capped at 5 percent. As of November 3, almost 98 percent of the overall budgeted direct support measures had been paid out while the take up for the first guarantee scheme was 59 percent and for the second scheme 42 percent. A third smaller support package was adopted on August 13, providing an additional minimum wage to public transport workers who resumed work one month later than the rest. The measure costing Lk135m is accommodated within the existing transport budget. 59ce067264
