Measuring the effects of Osteopathic Manipulative Treatment on range of motion in subjects with postural asymmetries in the posterior view: A potential implication for people with lateral spinal curvatures

Poor posture is a part of most people’s lives whether they are aware of it or not. While correcting a postural asymmetry has options, many interventions are painful, inconvenient, and/or socially stigmatized. For instance, back braces and surgery are typical ways in which to improve posture when the underlying problem is a spinal lateral curvature. However, Osteopathic Manipulative Treatment (OMT) may be a potential noninvasive treatment for spinal lateral curvatures, and my thesis research is centered on testing whether or not OMT improves range of motion and/or changes the overall shape of subjects with spinal lateral curvatures or postural asymmetries. The research I am conducting studies the efficacy of OMT on postural asymmetries using morphometric shape analysis. Morphometrics is able to detect differences in shape and pieces out the principle components of the shape; therefore it has the potential to determine whether OMT changes the shape of an individual’s back and increases range of motion. In my project, I am analyzing pre and post OMT treatment digital photographs taken of patients who received treatment in 2014 as part of joint study with the Department of Bio-Medical Sciences and the Department of Osteopathic Manipulative Medicine at PCOM. Photographs were prepared by placing landmarks on specific loci on their backs, which are then interpreted by the morphometrics programs. The morphometric shape analysis program enables us to visualize treatment progression through graph and statistical analysis. I present the results here on subjects who have completed nine treatments, specifically analyzing range of motion indicated by side bending to the left. The results for Bony landmark palpations showed the greatest change in shape when comparing groups of patients from a sham protocol and a treatment protocol, before the first day of treatments and after the ninth treatment. The first five Principle Component Analysis (PCA) Eigenvalues accounted for 84.674% indicating that landmarks five, six, seven, and ten had the most variation. In addition to PCA analysis, a warp analysis was done which shows the energy bends in the data and the same landmarks were indicated to shift the greatest amount. Furthermore, and analysis of shape as a function of the treatments was performed using the Canonical Variates Analysis (CVA). Results of the CVA for subjects as a function of treatment group, indicated that the treatment group had the largest change shift in morphospace on the graph, while sham did not shift as much. The same analyses were performed for semi-landmarks which traced the silhouette of the patients. Results indicate the semi data show that a majority of the shape change occurred around semi landmarks 31-41. These semi landmarks were on the left interior trunk of the subject. Landmark 31 was located on the left hip and 41 was under the left armpit region. These results may present an increase in range of motion for side bending to the left since these semi landmarks where indicative of the left side of the subjects. The CVA also showed a large shift in morphospace for OMT treated patients as opposed to sham patients

HE4 in the differential diagnosis of ovarian masses

Ovarian masses, a common finding among pre- and post-menopausal women, can be benign or malignant. Ovarian cancer is the leading cause of death from gynecologic malignancy among women living in industrialized countries. According to the current guidelines, measurement of CA125 tumor marker remains the gold standard in the management of ovarian cancer. Recently, HE4 has been proposed as emerging biomarker in the differential diagnosis of adnexal masses and in the early diagnosis of ovarian cancer. Discrimination of benign and malignant ovarian tumors is very important for correct patient referral to institutions specializing in care and management of ovarian cancer. Tumor markers CA125 and HE4 are currently incorporated into the Risk of Ovarian Malignancy Algorithm” (ROMA) with menopausal status for discerning malignant from benign pelvic masses. The availability of a good biomarker such as HE4, closely associated with the differential and early diagnosis of ovarian cancer, could reduce medical costs related to more expensive diagnostic procedures. Finally, it is important to note that HE4 identifies platinum non-responders thus enabling a switch to second line chemotherapy and improved survival

Low 25-OH vitamin D levels at time of diagnosis and recurrence of ovarian cancer.

The objective of this study was to evaluate the correlation between 25-OH vitamin D and ovarian cancer as a diagnostic marker or recurrence disease marker. We studied the following: (1) 61 women without gynecologic diseases, (2) 45 women affected by benign ovarian disease, (3) 46 women with recent diagnosis of ovarian cancer, (4) 26 follow-up women with recurrent ovarian cancer, and (5) 32 follow-up women with stable ovarian cancer. The 25-OH vitamin D was quantified with LUMIPULSE® G 25-OH vitamin D on LUMIPULSE® G 1200 (Fujirebio, Japan). As a threshold value, identified by ROC curve analysis, 20.2 ng/mL (sensitivity 73.3 %, specificity 84 %) was chosen corresponding to the limit between sufficient and insufficient 25-OH vitamin D according to the WHO. Low 25-OH vitamin D levels were observed in 26 % of women without gynecologic diseases, in 80 % of women with recent diagnosis of ovarian cancer and in 24 % women affected by benign ovarian diseases (p < 0.001). The follow-up study showed an insufficient level of 25-OH vitamin D in 73 % women with recurrent ovarian cancer and in 47 % women with stable ovarian cancer (p < 0.0003). This study showed that patients with ovarian cancer are often insufficient in 25-OH vitamin D compared to women with benign ovarian diseases. The women with recurrent ovarian cancer presented more often low levels compared to women with stable ovarian cancer. This study suggests that 25-OH vitamin D, due to its antiproliferative properties, can be a good marker for ovarian cancer also

Environmental contaminants exposure and preterm birth: a systematic review

Preterm birth is an obstetric condition associated with a high risk of infant mortality and morbidities in both the neonatal period and later in life, which has also a significant public health impact because it carries an important societal economic burden. As in many cases the etiology is unknown, it is important to identify environmental factors that may be involved in the occurrence of this condition. In this review, we report all the studies published in PubMed and Scopus databases from January 1992 to January 2019, accessible as full-text articles, written in English, including clinical studies, original studies, and reviews. We excluded articles not written in English, duplicates, considering inappropriate populations and/or exposures or irrelevant outcomes and patients with known risk factors for preterm birth (PTB). The aim of this article is to identify and summarize the studies that examine environmental toxicants exposure associated with preterm birth. This knowledge will strengthen the possibility to develop strategies to reduce the exposure to these toxicants and apply clinical measures for preterm birth prevention

Management of severe epistaxis during pregnancy: a case report and review of the literature

Epistaxis is a common problem during pregnancy. Few cases of severe epistaxis, not associated with nasal lesions or clotting disorders, were described in the literature. We reported a case of severe epistaxis in a pregnant patient, exploring all the different possible management options

Diversity of cervical microbiota in asymptomatic chlamydia trachomatis genital infection: a pilot study

Chlamydia trachomatis genital infection continues to be an important public health problem worldwide due to its increasing incidence. C. trachomatis infection can lead to severe sequelae, such as pelvic inflammatory disease, obstructive infertility, and preterm birth. Recently, it has been suggested that the cervico-vaginal microbiota may be an important defense factor toward C. trachomatis infection as well as the development of chronic sequelae. Therefore, the investigation of microbial profiles associated to chlamydial infection is of the utmost importance. Here we present a pilot study aiming to characterize, through the metagenomic analysis of sequenced 16s rRNA gene amplicons, the cervical microbiota from reproductive age women positive to C. trachomatis infection. The main finding of our study showed a marked increase in bacterial diversity in asymptomatic C. trachomatis positive women as compared to healthy controls in terms of Shannon's diversity and Shannon's evenness (P = 0.031 and P = 0.026, respectively). More importantly, the cervical microbiota from C. trachomatis positive women and from healthy controls significantly separated into two clusters in the weighted UniFrac analysis (P = 0.0027), suggesting that differences between the two groups depended entirely on the relative abundance of bacterial taxa rather than on the types of bacterial taxa present. Furthermore, C. trachomatis positive women showed an overall decrease in Lactobacillus spp. and an increase in anaerobes. These findings are part of an ongoing larger epidemiological study that will evaluate the potential role of distinct bacterial communities of the cervical microbiota in C. trachomatis infection

Role of galectin-3 combined with multi-detector contrast enhanced computed tomography in predicting disease recurrence in patients with ovarian cancer

Galectin-3 (Gal-3) is an endogenous β-galactoside-binding lectin, playing an important role in the pathogenesis of multiple malignancies. Aim of the study was to evaluate in a group of patients treated for ovarian cancer (EOC), the role of Gal-3 combined with multi-detector contrast-enhanced computed tomography (MDCT), as predictor of recurrence disease. Seventeen follow-up patients with recurrent ovarian cancer and 13 follow-up patients with stable ovarian disease, who performed MDCT at one-year follow-up after cytoreductive treatment, were enrolled. Serum Gal-3 concentrations were determined by using ELISA method. Twenty healthy controls were included in the analysis. Two radiologist blinded to patients status, reviewed MDCT exams, recording the following signs of disease recurrence: local tumor spread, enlarged lymph-nodes, carcinomatosis implants and metastases. We calculated the respective threshold values of Gal- 3 identified by ROC curve analysis for each imaging findings related to disease recurrence : lymphoadenopathies 92.45 ng/ml (AUC: 0.81, Se=91% Spe=73%), carcinomatosis 85.95 ng/ml (AUC:0.93 Se= 93.7%, Spe=92.8%), local tumor spread 99.05 (AUC:0.90, Se=100%, Spe=73% ) and metastasis 99.05ng/ml (AUC :0,78, Se=100% , Spe=70%). A significant correlation between high Gal-3 serum levels and presence of local tumor spread (n=11/17, p:0.001), carcinomatosis (n=16/17, p:0.00), lymphoadenopathies (n=15/17, p:0.00) and metastasis (n=11/17, p:0.003) related with recurrence disease was observed. Patients with recurrence of ovarian cancer presents higher Gal-3 values compared to women with stable diseases. Gal-3 combined to CECT should be used to improve the monitoring of EOC patients

Breastfeeding education: where are we going? A systematic review article

Background: UNICEF (United Nations International Children’s Emergency Fund) and WHO estimate that if all babies were breastfed for at least the first six months of their lives, the rate of morbidity and malnutrition would sig-nificantly decrease all over the world. In this view, these two organizations promoted a worldwide campaign for breastfeeding, creating the Baby Friendly Hospital Initiative (BFHI) that encourages good practices for the promotion of breastfeeding in hospitals. The aim of our study was to review the available evidence regarding the positive effects of breastfeeding, in order to suggest to most appropriate strategy to support it. Methods: The main databases including Scopus, PubMed, MEDLINE, Google scholar and Science Direct were researched to obtain the original papers related to breastfeeding education. The main terms used to literature search were "Breastfeeding education", Breastfeeding support", and “Breastfeeding healthcare policy”. The timeframe in-cluded the obtained articles was from 1980 to 2015. Results: Our analysis confirms that healthcare providers play a pivotal role in education and encouraging mothers to begin and continue breastfeeding. In this view, the adequate training of healthcare providers seems to be mandatory in order to support this practice. Moreover, adequate facilities are needed in order to promote and support breastfeeding. Conclusion: Considering the available evidence, breastfeeding should be supported among all the mothers. Based on the positive data emerging from the public awareness campaign in different Countries of the world, we strongly en-courage an accurate training for doctors and midwives and the implementation of adequate facilities in order to sup-port breastfeeding

Endometriosis: 10 keys points for MRI

Endometriosis is a chronic disease and a clinical problem in women of fertile age, with a high impact on quality of life, work productivity and health care management. Two imaging modalities are employed in the diagnosis and evaluation of extent of disease: ultrasound examination with endovaginal approach and magnetic resonance imaging (MRI). MRI, thanks to its high contrast and resolution characteristics, offers a high level of accuracy in the study of endometriosis and adenomyosis. We illustrate here 10 key MRI points for the detection and diagnosis of endometriosis
