Background: Hemodialysis (HD) is an important objective burden (task) on patient with end stage renal disease (ESRD) and the caregiver has a subjective burden which contributes to lifestyle changes, which result in depression, anxiety declining physical health, social isolation and financial strain. Aim: To evaluate the subjective burden on family caregiver who cares patient on maintenance hemodialysis therapy. Methods: Fifty main family caregivers for each patient on HD and the instrument were used by Caregiver Burden Interview (CBI) completed by caregiver as a major of subjective response to care giving. Results: The present study findings demonstrated that main age of caregiver was 40 (11.0) years, two thirds of females, and they were mostly married (78.0%) with children. The total family caregiver burden reported was 43.3 (21.7), role strain 50.0 (25.4) and the personal strain 39.5 (19.7). The total caregivers’ burden significantly positively correlated with the patients’ age (r = 0.461) and negatively correlated with patients’ level of education (r = ?0.290). Moreover the role strain, personal strain and total caregiver burden scores were statistically and significantly negatively correlated with their age (r = ?0.444) and level of education (r = ?0.416) and the total burden scores were ranked as moderately to severely burdened all family caregivers. Conclusion: Caregivers’ appraisal, coping strategies, interpersonal relationship issues, and social support would need to be considered for caregivers of patients maintained on HD.

Titanium alloys are extensively used in power, chemical and petroleum industries as constructional materials for vessels and heat transfer tubes. Moreover they are candidate materials for nuclear waste disposal. These alloys have superior resistance to localized forms of corrosion compared to stainless steels and Ni-base alloys. However, this resistance is not as remarkable in crevice corrosion conditions in some aggressive media. Electrochemical corrosion tests were conducted on two ASTM Ti grades namely, Ti-2 and Ti-12 in extremely low pH acidic environment. Results indicated that Ti-2 has less resistance to both general and crevice corrosion attack than Ti-12. Both alloys possess better resistance to general corrosion than to crevice corrosion. Also, results showed that the molybdate addition improves remarkably the resistance of Ti-2 to both types of attack. The increase of molybdate ions concentration from 0.03 mol/L to 0.15 mol/L made Ti-2 to be as resistant as, or somewhat higher than, Ti-12. The elecrochemical findings were further supplemented by optical examination of the corroded surface.

We really appreciated Geramizadeh, " Bile spillage and incidental gall bladder adenocarcinoma ", and Sandstrom et al. ,"Bile spillage should be avoided in elective cholecystectomy " (1,2). Both papers have been recently published in HepatoBiliary Surgery and Nutrition, 2019 (1,2). Starting from an analysis of the recent paper by Horkoff et al. "Adverse outcomes after bile spillage in incidental gall bladder cancer " in Annals of Surgery April 2019, they introduced a comprehensive discussion about epidemiology, diagnosis, therapy, prognostic factors and outcomes of incidental gallbladder cancer (1-3). They analyzed the possible risks related to bile spillage after cholecystectomy, in particular (1,2).

We read with pleasure papers by Cai et al. and Jia et al. published in HepatoBiliary Surgery and Nutrition, 2018, Volume 7, Issue 2 and 4, respectively (1,2). Both papers introduced comprehensive up-to-date literature reviews on indications and patient selection, surgical instruments, techniques, and outcomes of laparoscopic liver resections (LLRs) (1,2). Papers mentioned final statements by 2008 Louisville Statement and 2014 Morioka Consensus Conference (1,2). They stressed LLR non-inferiority to open procedures, in both minor and major liver resections as far as oncological and intraoperative/perioperative outcomes are concerned: reduced blood loss, lower postoperative morbidity and shorter length of hospitalization (1,2). Such results were corroborated by recent meta-analyses (3,4). Furthermore, some previous limitations for LLR look like they have been recently overcome (1-5). For example, tumor size, patient's old age and high BMI are no longer limitations for LLR, as Southampton Consensus guidelines suggested (5). Likewise, cirrhosis has been suggested as a further indication of LLR in highly selected patients with hepatocellular carcinoma and where it was performed by experienced surgeons (1-5).

AIM: To evaluate the safety and the efficacy of the ultrasound ciliary plasty(UCP) on the intraocular pressure(IOP) control in glaucomatous eyes without previous glaucoma ***: A retrospective study included patients with primary and secondary glaucoma who underwent UCP in Dar Al Shifa Hospital, Kuwait between January 2017 to June 2018. High-intensity focused ultrasound procedures were performed under peribulbar anesthesia using the 2^(nd) generation probe with 8 s duration of each of the 6 shots. Complete ophthalmologic examinations were scheduled pre-treatment, and at 1 d, 1 wk, 1, 3, 6 and 12 mo posttreatment. Primary outcomes were the IOP reduction and success rates at 12 mo, while the secondary outcomes were the occurrence of vision threatening complications and visual ***: The records of 62 eyes of 62 patients were analyzed with mean age of 63.8 y(67.7% males). There was statistically significant reduction in the mean IOP from 35.2±8.3 mm Hg before treatment to 20.6±8.7 mm Hg at 12^(th) month(P<0.0005) with a mean percentage IOP reduction of 42.3% with significant reduction in the mean number of antiglaucomatous drugs from 3.2±0.4 before treatment to 2.1±1.02 at 12 mo(P<0.0005). Qualified success was achieved in 77.4% of eyes at 12 mo. No major intra-or posttreatment complications were ***: Second-generation UCP prove to be effective in reducing IOP in naive glaucoma patients with lower success rates in cases of neovascular and uveitic glaucomas.

Since 1990, positioning technology has undergone a dramatic improvement in terms of accuracy and accessibility. Prior to 1990, national geodetic datums were considered to be static with fixed coordinates assigned to the datum origin by convention. Datum coordinates were dynamic only as a consequence of re-observation and re-adjustment, or localized disturbance. This strategy has been suitable for terrestrial surveys within stable continental areas. The accessibility of Precise Point Positioning “PPP” is now widespread with the provision of free online processing facilities by various geodetic agencies. Such ready accessibility to a global datum has serious implication for this technology with static geocentric datums. The Geocentric Datum of Egypt (ITRF1994 Epoch 1996 based on GPS Observation Campaign 1996), for example, is now offset by -42.0 to +32.0cm from the ITRF2008 Epoch 2015 due to the inexorable tectonic movements of the Nubian plate since the datum realization in 1996. Unless the local geocentric datums are kept in step with global terrestrial reference frames, discrepancies between the two will increase in magnitude over time and will become discernable, even using PPP. The PPP users nowadays are unaware of this datum offset and incorrectly assume that a coordinated datum monument is in error if there is found to be a disagreement greater than the level of accuracy of the positioning technique. In this study, to avoid the discrepancies between the applied datum and On-Line GNSS Services, a semi-kinematic datum and related deformation mode are proposed for Egypt. The result also confirmed that the PMM model was giving good performance for the other parts out of Egypt. The evaluation study shows the best performances for the Egyptian deformation model over the ITRF2008 PMM.
