A multi-centric, single-blinded, randomized, parallel-group study to evaluate the effectiveness of nasoalveolar moulding treatment in non-syndromic patients with complete unilateral cleft lip, alveolus and palate (NAMUC study): a study protocol for a randomized controlled trial.

BACKGROUND: Cleft lip and palate (CLP) are among the most common congenital anomaly that affects up to 33,000 newborns in India every year. Nasoalveolar moulding (NAM) is a non-surgical treatment performed between 0 and 6 months of age to reduce the cleft and improve nasal aesthetics prior to lip surgery. The NAM treatment has been a controversial treatment option with 51% of the cleft teams in Europe, 37% of teams in the USA and 25 of cleft teams in India adopting this methodology. This treatment adds to the already existing high burden of care for these patients. Furthermore, the supporting evidence for this technique is limited with no high-quality long-term clinical trials available on the effectiveness of this treatment. METHOD: The NAMUC study is an investigator-initiated, multi-centre, single-blinded randomized controlled trial with a parallel group design. The study will compare the effectiveness of NAM treatment provided prior to lip surgery against the no-treatment control group in 274 patients with non-syndromic unilateral complete cleft lip and palate. The primary endpoint of the trial is the nasolabial aesthetics measured using the Asher McDade index at 5 years of age. The secondary outcomes include dentofacial development, speech, hearing, cost-effectiveness, quality of life, patient perception, feeding and intangible benefits. Randomization will be carried out via central online system and stratified based on cleft width, birth weight and clinical trial site. DISCUSSION: We expect the results from this study on the effectiveness of treatment with NAM appliance in the long term along with the cost-effectiveness evaluation can eliminate the dilemma and differences in clinical care across the globe.

Diverse genetic origin of Indian Muslims: evidence from autosomal STR loci.

The origin and relationships of Indian Muslims is still dubious and are not yet genetically well studied. In the light of historically attested movements into Indian subcontinent during the demic expansion of Islam, the present study aims to substantiate whether it had been accompanied by any gene flow or only a cultural transformation phenomenon. An array of 13 autosomal STR markers that are common in the worldwide data sets was used to explore the genetic diversity of Indian Muslims. The austere endogamy being practiced for several generations was confirmed by the genetic demarcation of each of the six Indian Muslim communities in the phylogenetic assessments for the markers examined. The analyses were further refined by comparison with geographically closest neighboring Hindu religious groups (including several caste and tribal populations) and the populations from Middle East, East Asia and Europe. We found that some of the Muslim populations displayed high level of regional genetic affinity rather than religious affinity. Interestingly, in Dawoodi Bohras (TN and GUJ) and Iranian Shia significant genetic contribution from West Asia, especially Iran (49, 47 and 46%, respectively) was observed. This divulges the existence of Middle Eastern genetic signatures in some of the contemporary Indian Muslim populations. Our study reveals that the spread of Islamic faith in the Indian subcontinent was predominantly cultural transformation associated with minor gene flow from West Asia.

Platelets and Their Pathways in Dentistry: Systematic Review.

Advancing research in medicine and technology has benefitted the mankind immensely with its contribution toward an improved life quality and increased life expectancy. The inability of a human body to autoregenerate has resulted in an increased demand for newer and healthier tissues and organs. Therefore, the restoration of naturally replicated tissue components has become a subject of interest for the scientific community lately. There was felt an intense quest for promoting strategies that could restore tissue regeneration and fuel the field of regenerative medicine. It was then the role of platelets was accounted for its wound healing and regenerative effects. Consequently, the use of platelet concentrates to improve wound healing, and bone formation was explored, which was considered to be possible because platelets contain high quantities of growth factors which would be able to stimulate cell proliferation, matrix remodeling, and angiogenesis, thereby establishing a new era of research with the successful application of innovative medical therapies focused on healing damaged tissues or regenerate the affected organs.

Traces of sub-Saharan and Middle Eastern lineages in Indian Muslim populations.

Islam is the second most practiced religion in India, next to Hinduism. It is still unclear whether the spread of Islam in India has been only a cultural transformation or is associated with detectable levels of gene flow. To estimate the contribution of West Asian and Arabian admixture to Indian Muslims, we assessed genetic variation in mtDNA, Y-chromosomal and LCT/MCM6 markers in 472, 431 and 476 samples, respectively, representing six Muslim communities from different geographical regions of India. We found that most of the Indian Muslim populations received their major genetic input from geographically close non-Muslim populations. However, low levels of likely sub-Saharan African, Arabian and West Asian admixture were also observed among Indian Muslims in the form of L0a2a2 mtDNA and E1b1b1a and J(*)(xJ2) Y-chromosomal lineages. The distinction between Iranian and Arabian sources was difficult to make with mtDNA and the Y chromosome, as the estimates were highly correlated because of similar gene pool compositions in the sources. In contrast, the LCT/MCM6 locus, which shows a clear distinction between the two sources, enabled us to rule out significant gene flow from Arabia. Overall, our results support a model according to which the spread of Islam in India was predominantly cultural conversion associated with minor but still detectable levels of gene flow from outside, primarily from Iran and Central Asia, rather than directly from the Arabian Peninsula.
