Background: Globally, malaria is still a major public health challenge. Drug-based treatment is the primary intervention in malaria control and elimination. However, optimal use of mass or targeted treatments remains unclear. A variety of radical, preventive and presumptive treatment regimens have been administrated in China and a systematic review was conducted to evaluate effectiveness, and discuss experiences, limitations, and lessons learnt in relation to the use of these regimens.
Methods: The search for information includes both paper documents, such as books, malaria control annals and guidelines for malaria prevention and treatment, as well as three computer-based databases in Chinese (CNKI, WanFangdata and Xueshu.baidu) and two databases in English (PubMed and Google Scholar), to identify original articles and reports associated with drug administration for malaria in China.
Results: Starting from hyperendemicity to elimination of malaria in China, a large number of radical, preventive and presumptive treatment regimens had been tried. Those effective regimens were scaled up for malaria control and elimination programmes in China. Between 1949 and 1959, presumptive treatment with available anti-malarial drugs was given to people with enlarged spleens and those who had symptoms suggestive of malaria within the last 6 months. Between 1960 and 1999, mass drug administration (MDA) was given for preventive and radical treatment. Between 2000 and 2009, the approach was more targeted, and drugs were administed only to prevent malaria infection in those at high risk of exposure and those who needed radical treatment for suspected malaria. Presumptive therapy was only given to febrile patients. From 2010, the malaria programme changed into elimination phase, radical treatment changed to target individuals with confirmed either Plasmodium vivax or Plasmodium ovale within the last year. Preventive treatment was given to those who will travel to other endemic countries. Presumptive treatment was normally not given during this elimination phase. All cases of suspected were confirmed by either microscopy or rapid diagnosis tests for malaria antigens before drugs were administered. The engagement of the broader community ensured high coverage of these drug-based interventions, and the directly-observed therapy improved patient safety during drug administration.
Conclusion: A large number of radical, preventive and presumptive treatment regimens for malaria had been tried in China with reported success, but the impact of drug-based interventions has been difficult to quantify because they are just a part of an integrated malaria control strategy. The historical experiences of China suggest that intervention trials should be done by the local health facilities with community involvement, and a local decision is made according to their own trial results.

Purpose: To describe a rare case of presumed bilateral acute idiopathic maculopathy (AIM) in a pediatric patient.
Observation: An 11-year-old male was evaluated for a "fuzzy Dorito-shaped" spot in the central vision of his right eye (OD) that started 3 days before presenting to our clinic. On examination, best-corrected visual acuity (BCVA) was counting fingers at 5 feet OD, and 20/25 in the left eye (OS).

Uterine fibroids are benign monoclonal neoplasms of the myometrium, representing the most common female pelvic neoplasms globally. Treatments may be invasive, such as hysterectomy and myomectomy, non-invasive, such as medical therapy or focused ultrasound, or minimally invasive, such as transcervical radiofrequency ablation (TFA). To date, more than 12,000 women have been treated worldwide using TFA with the Sonata System.

Background: Protein requirements established for healthy populations may be insufficient to support healthy growth in infants consuming largely cereal-based complementary foods and frequently exposed to enteric pathogens.
Objective: To assess independent and combined effects of protein supplementation and antibiotic treatment on linear growth of infants from 6-12 months of age.
Design: We conducted a 2 x 4 factorial cluster-randomized trial in northwestern Bangladesh, allocating 566 clusters to masked azithromycin (10 mg·kg * 3 d) or placebo at 6 and 9 months of age, and unmasked delivery of an egg white protein-rich blended food supplement (250 kcal; 10 g added protein), a rice-based isocaloric supplement, egg, or nutrition education from 6-12 months.

Background: With the proportion of tuberculosis cases that are extrapulmonary tuberculosis (EPTB) increasing in recent years, understanding and addressing factors contributing to the prolonged time to diagnosis (TTD) of EPTB patients is vital.
Methods: We enrolled presumptive EPTB patients for a cohort study from 2018-2020 in Ujjain, India. Based on a structured questionnaire, the patients were interviewed for socio-demographic and clinical information, including previously visited health facilities (HF) for this illness.
