RESUMO
Pithecellobium dulce, an evergreen medium-sized, spiny tree, each part of the plant has vast nutritional values; stuffedwith essential vitamins, amino acids, and minerals. The fruits of P. dulce were widely used in Ayurvedic medicinesand home remedies. The plant has also been a rich source of biologically active compounds such as tannin, olein,and glycosides. Totally 38 active phytocompounds like quercetin, kaempferol, and dulcitol were identified from thevarious parts of the plant. Notably, this plant has catechol type of tannins in the bark. There are polyphenol classesof phytocompounds which have found to hold potent antivenom activity. Their fruits are a rich source of phenols,flavonoids, and saponins reported for their efficacy to treat diabetes, oxidative stress, and gastrointestinal disorders.The plant leaf and seed have an antibacterial, antifungal, and adulticidal activities. Thus, the present review describeson exploiting the medicinal properties of P. dulce and its biomedicinal applications in therapeutic development.
RESUMO
Resumen Introducción: La relevancia de los medicamentos para la salud depende de su calidad, acceso y correcto uso. Objetivos: Determinar el valor terapéutico potencial de los antibióticos no incluidos en la lista de medicamentos esenciales (LME) de la Organización Mundial de la Salud pero que forman parte del Cuadro Básico de Medicamentos (CBM) de la Secretaría de Salud de México y categorizarlos por su valor intrínseco. Método: Análisis descriptivo de los antibióticos no incluidos en la LME de la Organización Mundial de la Salud 2013, revisión de la literatura para obtener evidencia de eficacia y seguridad y aplicación de escala de calidad y de valor intrínseco. Resultados: Se identificaron 452 resúmenes para 19 antibióticos, se eliminaron 56.9 %. In extenso se revisaron 195 ensayos clínicos; 37.9 % fueron de calidad y se determinó valor intrínseco; 54 % fueron estudios de superioridad y 46 % de no inferioridad o equivalencia; 32 % de los antibióticos fueron clasificados sin valor intrínseco y aproximadamente 50 % fueron dudosos. Conclusión: Una elevada proporción de antibióticos del CBM tuvo valor intrínseco dudoso o nulo, lo que favorece su uso inapropiado, resistencia bacteriana y coloca a la población en riesgo.
Abstract Introduction: The relevance of medications for health depends on their quality, accessibility and appropriate use. Objective: To determine the potential therapeutic value of antibiotics that are not included in the World Health Organization Essential Medicines List (EML) but that are part of the National Essential Medicines List (NEML) of the Mexican Ministry of Health, and categorize them according to their intrinsic value. Method: Descriptive analysis of antibiotics not included in the 2013 World Health Organization EML; literature review to obtain efficacy and safety evidence; and application of quality and intrinsic value scales. Results: Four hundred and fifty-two abstracts were identified for 19 antibiotics; 56.9 % were excluded; 195 clinical trials were reviewed in full-text articles, out of which 37.9 % were of good quality, and intrinsic value was determined; 54 % were superiority studies, whereas 46 % were non-inferiority or equivalence studies; 32 % of the antibiotics were classified without intrinsic value and nearly 50 % were inconclusive. Conclusion: An elevated proportion of antibiotics of the NEML had uncertain or no intrinsic value, which favors their inappropriate use, bacterial resistance and puts the population at risk.

Hookworm infection remains a global health concern, which threatens human health. Hookworm infection is widely prevalent across the world, notably in tropical and subtropical areas. Recently, with the in-depth study of the immunity of parasitic infections, the“bidirectional effect”of host immune responses induced by helminth infections (including hookworm infections) has become increasingly prominent. On one hand, an immune response is induced in the host to kill the infected worms; on the other hand, the host produces a series of immunological changes that are conducive to the maintenance of parasite survival. The immune state of the host is regulated by various complicated mechanisms, and this may lead to the reduction in the incidence of allergic and autoimmune diseases or alleviation of the disease symptoms, which provide new insights into the management of these allergic and autoimmune diseases. The present article reviewed the advances of host immune responses induced by hook-worm infection and its potential values in the treatment of allergic asthma, inflammatory bowel disease and rheumatoid arthritis.
