Senior housestaff and junior faculty are often expected to perform clinical research, yet may not always have the requisite knowledge and skills to do so successfully. Formal degree programs provide such knowledge, but require a significant commitment of time and money. Short-term training programs (days to weeks) provide alternative ways to accrue essential information and acquire fundamental methodological skills. Unfortunately, published information about short-term programs is sparse. To encourage discussion and exchange of ideas regarding such programs, we here share our experience developing and implementing INtensive Training in Research Statistics, Ethics, and Protocol Informatics and Design (INTREPID), a 24-day immersion training program in clinical research methodologies. Designing, planning, and offering INTREPID was feasible, and required significant faculty commitment, support personnel and infrastructure, as well as committed trainees.

Effect of mobile phone reminders on follow-up medical care of children exposed to or infected with HIV in Cameroon (MORE CARE): a multicentre, single-blind, factorial, randomised controlled trial
Bigna, Jean Joel R; Noubiap, Jean Jacques N; Kouanfack, Charles; Plottel, Claudia S; Koulla-Shiro, Sinata
BACKGROUND: Missed scheduled HIV appointments lead to increased mortality, resistance to antiretroviral therapy, and suboptimum virological response. We aimed to assess whether reminders sent to carers by text message, mobile phone call, or concomitant text message and mobile phone call increase attendance at medical appointments for HIV care in a population of children infected with or exposed to HIV in Cameroon. We also aimed to ascertain the most cost-effective method of mobile-phone-based reminder. METHODS: MORE CARE was a multicentre, single-blind, factorial, randomised controlled trial in urban, semi-urban, and rural settings in Cameroon. Carers of children who were infected with or had been exposed to HIV were randomly assigned electronically in blocks of four and allocated (1:1:1:1) sequentially to receive a text message and a call, a text message only, a call only, or no reminder (control). Investigators were masked to group assignment. Text messages were sent and calls made 2 or 3 days before a scheduled follow-up appointment. The primary outcomes were efficacy (the proportion of patients attending a previously scheduled appointment) and efficiency (attendance/[measures of staff working time x cost of the reminders]), as a measure of cost-effectiveness. The primary analysis was by intention to treat. This study is registered with the Pan African Clinical Trials Register, number PACTR201304000528276. FINDINGS: The study took place between Jan 28 and May 24, 2013. We randomly assigned 242 adult-child (carer-patient) pairs into four groups: text message plus call (n=61), call (n=60), text message (n=60), and control (n=61). 54 participants (89%) in the text message plus call group, 51 (85%) in the call group, 45 (75%) in the text message group, and 31 (51%) in the control group attended their scheduled appointment. Compared with control, the odds ratios for improvement in the primary efficacy outcome were 7.5 (95% CI 2.9-19.0; p<0.0001) for text message plus call, 5.5 (2.3-13.1; p=0.0002) for call, and 2.9 (1.3-6.3; p=0.012) for text message. No significant differences were seen in comparisons of the three intervention groups with each other, and there was no synergism between text messages and calls. For the primary efficiency outcome, the mean difference for text message versus text message plus call was 1.5 (95% CI 0.7 to 2.4; p=0.002), for call versus text message plus call was 1.2 (0.7 to 1.6; p<0.0001), and for call versus text message was 0.4 (-1.3 to 0.6; p=0.47). INTERPRETATION: Mobile-phone-based reminders of scheduled HIV appointments for carers of paediatric patients in low-resource settings can increase attendance. The most effective method of reminder was text message plus phone call, but text messaging alone was the most efficient (ie, cost-effective) method. FUNDING: No external funding.

A randomized blinded controlled trial of mobile phone reminders on the follow-up medical care of HIV-exposed and HIV-infected children in Cameroon: study protocol (MORE CARE)
Bigna, Jean Joel; Kouanfack, Charles; Noubiap, Jean Jacques; Plottel, Claudia S; Koulla-Shiro, Sinata
BACKGROUND: In Cameroon, only two-thirds of children with HIV exposure or infection receive appropriate HIV-directed medical care. Mortality, antiretroviral therapy resistance and suboptimal virological response are strongly related to missed opportunities for treatment, and, more specifically, to skipped scheduled medical appointments. The present trial, MORE CARE (Mobile Reminders for Cameroonian Children Requiring HIV Care) seeks to determine if reminders sent by text message (SMS), phone call, or concomitant SMS and phone calls most increase the presence at medical appointments of HIV-infected or -exposed children (efficacy), and which is the most efficient related to working time and financial cost (efficiency). METHODS: We will carry out a multicenter single-blind, randomized, factorial controlled trial. A randomization list will be electronically generated using random block sizes. Central allocation will be determined by sequentially numbered. A total of 224 subjects will be randomized into four groups (SMS, Call, SMS + Call, and Control) with an allocation ratio of 1:1:1:1. SMS and calls will be sent between 48 and 72 hours before the scheduled appointment. A medical assistant will send out text messages and will call participants. Our primary outcome is appointment measured by efficacy and efficiency of interventions. We hypothesize that two reminders (concomitant use of SMS and phone calls) as an appointment reminder is more effective to improve appointment compared to one reminder (only SMS or only call), and that the most efficient is use of only SMS. The analysis will be intention to treat. DISCUSSION: This trial investigates the potential of SMS and phone calls as motivational reminders to improve children's adherence to medical appointments for HIV-related care in Cameroon. The intervention will act to end missed appointment due to forgetfulness.Trial registration: Pan African Clinical Trials Registry: PACTR201304000528276.

Microbiome and malignancy
Plottel, Claudia S; Blaser, Martin J
Current knowledge is insufficient to explain why only a proportion of individuals exposed to environmental carcinogens or carrying a genetic predisposition to cancer develop disease. Clearly, other factors must be important, and one such element that has recently received attention is the human microbiome, the residential microbes including Bacteria, Archaea, Eukaryotes, and viruses that colonize humans. Here, we review principles and paradigms of microbiome-related malignancy, as illustrated by three specific microbial-host interactions. We review the effects of the microbiota on local and adjacent neoplasia, present the estrobolome model of distant effects, and discuss the complex interactions with a latent virus leading to malignancy. These are separate facets of a complex biology interfacing all the microbial species we harbor from birth onward toward early reproductive success and eventual senescence
