Abstract Aim: To test the feasibility of our ultrasound protocol in evaluating the physiological changes during breast milk expression, and the impact of breast massage on temperature, blood flow and tension.Method: Breast massage was used for the right breast, and the left breast had no massage. Temperature was measured at baseline, post massage (for right breast), and post pump. The ultrasound scans were performed using a Toshiba Aplio 500 system (Toshiba Medical Systems, Otawara, Japan). B-mode, doppler ultrasound and shear wave elastography (SWE) were used. Blood flow of the IMA and LTA were measured at baseline, post massage (for right breast), 10 minutes into pump (relaxation and tension phase), and post pump. SWE was used to measure breast tension during the tension and relaxation phase of breast pump, after the breast milk was completely drained.Results: There was a slight decrease in breast temperature post massage, and further decreased post pump. With breast massage, the SWE values were higher at relaxation phase compared to no massage (left breast). However, with massage, the tension phase also showed less increase of SWE values compared to no massage, and appeared to be lower than no massage. Blood flow of IMA did not appear to follow a particular trend, with and without massage. Conclusion: Breast massage prior to pumping breast milk helped to reduce the temperature of the breast, showing that it has an effect in relieving breast engorgement. Massage also reduced the tension of the breast during the pump tension (suction) phase. There was no observable trend of massage on blood flow in both the IMQ and LTA.

Masseter Muscles

In children, the quality and muscle function are altered in many pathologic conditions, including temporomandibular disorders. Although several methods have been used to evaluate muscle tonus, none became a golden standard. Moreover, the masseter muscle characteristics in children have not been investigated to date. This study aimed to measure the stiffness of the masseter muscle using shear-wave elastography in healthy children. We enrolled 30 healthy children (mean age 10.87 ± 3.38 years). The stiffness of masseter muscles was measured with shear wave elastography. Stiffness for the total sample was 6.37 ± 0.77 kPa. A comparison of the measurements did not show significant differences between the right and the left masseter muscles (left—6.47 ± 0.78 kPa; right—6.24 ± 0.76 kPa; p = 0.3546). A significant difference was seen between boys and girls (boys—5.94 ± 0.50 kPa; girls—6.63 ± 0.80; p = 0.0006). Shear-wave elastography is a promising diagnostic tool. It may help to detect changes in the stiffness of the masseter muscle and draw attention to pathological processes within the jaw muscles. Directions for further research shall include determining stiffness values in pathological conditions and the impact of biological and functional factors on the stiffness of the masseter muscle.

Despite its beneficial effects on flexibility and muscle soreness, there is still conflicting evidence regarding dose-response relationships and underlying mechanisms of foam rolling (FR). This study aimed to investigate the impact of different FR protocols on tissue perfusion and tissue stiffness. In a randomized crossover trial, two FR protocols (2x1 min, 2x3 min) were applied to the right anterior thigh of twenty healthy volunteers (11 females, 25 ± 4 years). Tissue perfusion (near infrared spectroscopy, NIRS) and stiffness (Tensiomyography, TMG and Myotonometry, MMT) were assessed before and after FR application. Variance analyses revealed a significant interaction of FR duration and tissue perfusion (F[1,19] = 7.098, p = 0.015). Local blood flow increased significantly from pre to post test (F[1,19] = 7.589, p = 0.013), being higher (Δ +9.7%) in the long-FR condition than in the short-FR condition (Δ +2.8%). Tissue stiffness (MMT) showed significant main effects for time (F[1,19] = 12.074, p = 0.003) and condition (F[1,19] = 7.165, p = 0.015) with decreases after short-FR (Δ -1.6%) and long-FR condition (Δ -1.9%). However, there was no time*dose-interaction (F[1,19] = 0.018, p = 0.895). No differences were found for TMG (p > 0.05). FR-induced changes failed to exceed the minimal detectable change threshold (MDC). Our data suggest that increased blood flow and altered tissue stiffness may mediate the effects of FR although statistical MDC thresholds were not achieved. Longer FR durations seem to be more beneficial for perfusion which is of interest for exercise professionals designing warm-up and cool-down regimes. Further research is needed to understand probable effects on parasympathetic outcomes representing systemic physiological responses to locally applied FR stimulations.

The Relationship

Induced lactation is a method of stimulating breast milk, carried out by non-pregnant women. It is an alternative for women who are unable to have children naturally but wish to experience motherhood by adopting. In Islamic laws, breastfeeding by a woman of another person’s child will turn their relationship into that of a mother and her own child. The permissibility in Islamic law of breastfeeding another person’s child has been taken as an alternative way for adoptive Muslim mothers to “mahram”ise (a male/female who is forbidden permanently, forever) (or familiarize) the relationship with that adopted child. The objective of this study is to explore the experience of adoptive mothers who have breastfed their adopted children through the method of induced lactation. This study focuses on the technical aspects, on how an adoptive mother stimulates the production of breast milk despite not having gone through the process of pregnancy. This study uses the qualitative study method. This study interviewed 12 respondents comprising of Muslim females who had successfully nursed their adopted children before the age of two and fulfilled the requirement to nurse the child until he is fully satisfied for five sessions. The semi structured interview technique was carried out over a 6 months period between the years 2012 to 2013. Data analysis discovered that two methods of induced lactation were performed, i.e., hormone simulation and breast stimulation. This study also found two devices used in the process of breast stimulation, which are Supplemental Feeding Device and Breast pump. In summary, the process of induced lactation to nurse an adopted child can be a success with the right method, technique and equipment.

Abstract Background Primary graft dysfunction (PGD) remains a major obstacle after lung transplantation. Ischemia–reperfusion injury is a known contributor to the development of PGD following lung transplantation. We developed a novel approach to assess the impact of increased pulmonary blood flow in a large porcine single-left lung transplantation model. Materials Twelve porcine left lung transplants were divided in two groups (n = 6, in low- (LF) and high-flow (HF) group). Donor lungs were stored for 24 h on ice, followed by left lung transplantation. In the HF group, recipient animals were observed for 6 h after reperfusion with partially clamping right pulmonary artery to achieve a higher flow (target flow 40–60% of total cardiac output) to the transplanted lung compared to the LF group, where the right pulmonary artery was not clamped. Results Survival at 6 h was 100% in both groups. Histological, functional and biological assessment did not significantly differ between both groups during the first 6 h of reperfusion. injury was also present in the right native lung and showed signs compatible with the pathophysiological hallmarks of ischemia–reperfusion injury. Conclusions Partial clamping native pulmonary artery in large animal lung transplantation setting to study the impact of low versus high pulmonary flow on the development of ischemia reperfusion is feasible. In our study, differential blood flow had no effect on IRI. However, our findings might impact future studies with extracorporeal devices and represent a specific intra-operative problem during bilateral sequential single-lung transplantation.

Background: Complaints regarding medical practice represent a harsh reality of the current world. Patients have the right to receive explanations and compensation when they are injured during the medical act, but the increased potential for exposure to complaints determines personal and professional consequences for the doctors, with significant impact on their health and practice. Thus, the aim of our research was to analyze in depth the impact of complaints on the doctors involved. Materials and methods: The authors conducted a qualitative study, using a semi-structured interview, addressed to doctors who had complaints from patients. The participants in our research were identified using an adapted version of the snowball method. Results: After the analysis of the interviews using the inductive method, nine themes resulted, seven of which are addressed in this paper: injustice, personal impact, professional impact, difficulties, supportive factors, the attitude of the hospital management and the attitude of colleagues. At the personal level, the doctors were overwhelmed by insomnia, nightmares, stress and anxiety, and at the professional level by doubts about medical decisions, fear, anxiety and the tendency to avoid patients with severe diseases. Conclusions: The study revealed that physicians who had complaints from patients are deeply affected by the complaint itself and the associated investigation procedure, even if, to a lesser extent, some of the participants found motivation for a better management of the situation. The study also showed the need for changes in the legal and medical systems in order to create mechanisms to support the doctors during the investigation process.

PurposeBoth tinnitus and type 2 diabetes mellitus (T2DM) are linked with cognitive decline and brain dysfunction. This study used arterial spin labeling (ASL) perfusion functional magnetic resonance imaging (fMRI) to examine the abnormal cerebral blood flow (CBF) patterns existed in tinnitus patients and potential relationships between the abnormal CBF and cognitive performance. The impact of T2DM on CBF alterations in tinnitus patients was further explored.MethodsSixty tinnitus patients and 40 non-tinnitus subjects were recruited. CBF images were collected and analyzed using ASL perfusion fMRI. Brain regions with CBF alterations between tinnitus patients and non-tinnitus controls were identified by one-way analysis of variance. Interaction effects between tinnitus and T2DM for CBF changes were also selected. Then, correlation analyses were calculated to specify the link between CBF changes and cognitive performance and between CBF changes and diabetic characteristics.ResultsTinnitus patients showed decreased CBF, primarily in the auditory area and default mode network (DMN), compared with non-tinnitus controls. Decreased CBF in these regions was correlated with executive function and attention. The interaction effect between tinnitus and T2DM was significant in the right medial prefrontal gyrus. Additionally, CBF in the right medial prefrontal gyrus was correlated with tinnitus distress and cognitive performance. In tinnitus patients, Hemoglobin A1c was associated with CBF in the right medial prefrontal gyrus.ConclusionTinnitus affects brain perfusion in the auditory area and DMN. T2DM and uncontrolled glucose levels may aggravate a CBF decrease in tinnitus patients. These new findings implied that tinnitus patients may benefit from blood glucose control in terms of their cognitive function and tinnitus distress.

Abstract. In the study, the neural basis of emotional reactivity was investigated. Reactivity was operationalized as the impact of emotional pictures on the self-reported ongoing affective state. It was used to divide the subjects into high- and low-responders groups. Independent sources of brain activity were identified, localized with the DIPFIT method, and clustered across subjects to analyse the visual evoked potentials to affective pictures. Four of the identified clusters revealed effects of reactivity. The earliest two started about 120 ms from the stimulus onset and were located in the occipital lobe and the right temporoparietal junction. Another two with a latency of 200 ms were found in the orbitofrontal and the right dorsolateral cortices. Additionally, differences in pre-stimulus alpha level over the visual cortex were observed between the groups. The attentional modulation of perceptual processes is proposed as an early source of emotional reactivity, which forms an automatic mechanism of affective control. The role of top-down processes in affective appraisal and, finally, the experience of ongoing emotional states is also discussed.
