Introduction: Evolution of laparoscopy has revolutionised the field of gynaecological surgery for more than 40 years.Owing to the long learning curve, added expenses and lack of awareness among patients and surgeons, its introduction and development in Nepal is not upto the timeline. Gynaecologic laparoscopy (GL) seems to be introduced at BP Koirala institute of Health Sciences, Dharan,Nepal (BPKIHS) since 2002. It remained in latency because of widespread lack of equipment and skilled personnel. Some laparoscopic procedures like diagnostic laparoscopy, laparoscopic tubal ligation and very few laparoscopic assisted vaginal hysterectomy (LAVH) were done from 2002 - 2012 (10 years). Since then more gynecologists  have been trained in GL which has contributed to expansion of GL. Objective: The objective of this study is to study and share trends of gynaecological laparoscopic surgeries performed at BPKIHS. Methodology: All the patients undergoing GL surgeries have been analyzed for the indication, type of procedure, conversion and its complications.  We took data from operation theatre register and patient case sheet from July 2004 to May 2018. We divided this period into two phase viz Phase 1: July 2004-June 2013 and Phase 2: July 2013- till May 2018. Results: Total number of GL done in this period was 427. Out of which 102 cases were from phase one and rest of the cases were done in five years of phase II. Number of operative laparoscopy has increased in phase 2 compared to phase 1. In last five years there was155 (47.6%) cases of adnexal surgery, 77 (23.6%) cases of diagnostic laparoscopy.Total laparoscopic hysterectomy was done in 25 (7.6%) cases. Conversion to laparotomy was done in4.6% (n=15) cases. Overall 12(3.7%) patient had major complications. Oral diet started at 4-6th hour post-operatively, and mobilization started after 24 hours. Seventy percent of patient had a hospital stay of 2days and rest stayed for 3 days. Conclusions: There is rising trend in operative GL at BPKIHS.  We are facing less complication with expanding experience. There has been good learning from each case. GL has well demonstrated its advantages of reducing postoperative pain and morbidity, short hospital stay, and less postoperative recovery time. We have plans to get new gadgets and expand services in GL.

Background: Hysterectomy is one of the most commonly performed major surgeries. Recently, increasing number of minimally invasive approaches, such as TLH and LAVH has been applied. People undergoing laparoscopic hysterectomy experience shorter hospitalization, a smaller wound, more rapid recovery, and shorter absence from work compared to patients undergoing abdominal hysterectomy. The objective of present study is to compare the surgical short term results between Laparoscopic assisted vaginal hysterectomy (LAVH) and Total laparoscopic hysterectomy (TLH) in our centre in two years.Methods: This was a retrospective study of 93 women who underwent LAVH and 55 women who underwent TLH. The statistical analysis is done by using Students t-test, Chi-square test, and Mann-Whitney test appropriately.Results: There were no differences between the two groups with respect to age, BMI, Indication of surgery, Uterine size, Previous pelvic surgery, average blood loss and hemoglobin change (P=0.4). The duration of surgery was longer in TLH (124 min vs. 76.9 min) and is found to be extremely significant (P=0.0001). There was significant statistical difference in respect to hospital stay (P=0.0076). There was no significant statistical difference in various complication rates (P=0.22).Conclusions: Both TLH and LAVH are safe methods in performing hysterectomy, but LAVH has advantages over TLH with reduced operating time and less hospital stay even for the patients with history of previous pelvic surgery.

Objective: The cytomorphological criteria of malignant endometrial lesions in cervical samples are less well described than those of cervical lesions. We wished to investigate if there were features in SurePath™ liquid-based cytology samples that would facilitate more accurate differentiation between benign and malignant endometrial cells. Study Design: This was a two-phase study, with a review of all SurePath™ samples reported as endometrial adenocarcinoma (n = 42) evaluating 12 cytological features in the first phase. In phase 2 (test set), all initial cases plus an additional 83 cases were reviewed using these 12 cytological features to predict the outcome. Results: Out of 12 cytological features evaluated in phase 1 (training set), nuclear chromatin pattern, apoptotic bodies and tingible body macrophages were found to be the most significant features determining malignant histological outcome. These 12 cytological features were re-evaluated in phase 2 (n = 125). Of 125 cases, 54 had a benign and 71 had a malignant or premalignant histological outcome, with a positive predictive value of 56.8%. Conclusion: Granular nuclear chromatin, tingible body macrophages and apoptosis in the background are the most significant factors in determining whether endometrial cells present in cervical samples represent malignancy or are benign. Using these features, relatively accurate predictions of endometrial pathology can be made.

Background Psychosocial rehabilitation is a service that supports recovery from mental illness by providing opportunities for skill development, self-determination, and social interaction. One type of psychosocial rehabilitation is the Clubhouse model. The purpose of the current project was to create, test, and refine a realist theory of psychosocial rehabilitation at Progress Place, an accredited Clubhouse. Method Realist evaluation is a theory driven evaluation that uncovers contexts, mechanisms, and outcomes, in order to develop a theory as to how a program works. The current study involved two phases, encompassing four steps: Phase 1 included (1) initial theory development and (2) initial theory refinement; and Phase 2 included (3) theory testing and (4) refinement. Results The data from this two-phase approach identified three demi-regularities of recovery comprised of specific mechanisms and outcomes: the Restorative demi-regularity, the Reaffirming demi-regularity, and the Re-engaging demi-regularity. The theory derived from these demi-regularities suggests that there are various mechanisms that produce outcomes of recovery from the psychosocial rehabilitation perspective, and as such, it is necessary that programs promote a multifaceted, holistic perspective on recovery. Conclusions The realist evaluation identified that Progress Place promotes recovery for members. Additional research on the Clubhouse model should be conducted to further validate that the model initiates change and promotes recovery outcomes.

Purpose The purpose of this paper is to report on an evaluation of the UK Healthy Universities Network (UKHUN), which explored engagement of network members; identified what members value about the network; examined facilitators and barriers to engagement; and informed the network’s future development. Design/methodology/approach The study was a two phase mixed-method study, with participants being staff from Higher Education institutions. Phase 1 involved a documentary review and an online 14-question survey (n=32). Phase 2 comprised follow-up semi-structured interviews and focus groups, conducted using Skype (n=11). These were audio recorded and transcripts were thematically analysed in a two-stage process. Findings A number of key themes emerged from the thematic analysis: value of network meetings and events; popularity of the network website; increased communication and collaboration; sense of leadership offered by the network; interest and inclusion of an international perspective; importance of institutional support. Research limitations/implications Only six universities who are involved in the network took part in Phase 2. Although a range of organisations were chosen purposively, it is possible that additional key issues at other universities were excluded. Originality/value The UKHUN is valued by its membership, particularly its biannual meetings, online presence, leadership, ethos and communication methods. Key barriers include the capacity of staff to attend meetings and contribute to the network, influenced by a lack of institutional commitment and prioritisation. Findings from the evaluation have informed a “refresh” of the network’s website and a revision of its membership structure, as well as guiding its positioning to achieve greater strategic influence.

In this paper we derive and implement a maximum‐likelihood deconvolution (MLD) algorithm, based on the same channel and statistical models used by Kormylo and Mendel (1983a), that leads to many fewer computations than their MLD algorithm. Both algorithms can simultaneously estimate a nonminimum phase wavelet and statistical parameters, detect locations of significant reflectors, and deconvolve the data. Our MLD algorithm is implemented by a two‐phase block component method (BCM). The phase‐1 block functions like a coarse adjustment of unknown quantities and provides a set of good initial conditions for the phase‐2 block, which functions like a fine adjustment of unknown quantities. We demonstrate good performance of our algorithm for both synthetic and real data.

e18093 Background: The purpose of this study is to determine and compare the overall rates of surgical site infections (SSI) in patients undergoing breast surgery, hysterectomy and combined breast surgery and hysterectomy. Methods: We inspected the National Surgical Quality Improvement Program (NSQIP) Participant Use Files from 2005-2014 for subjects undergoing breast surgery (CPT codes 19300-19307, 19340, 19342, 19350, 19357, 19361, 19364, 19366-19369, 19380, 19396), Gynecologic surgery ( CPT Codes 58150, 58152, 58180, 58200, 58210, 58240, 58260, 58262, 58263, 58267, 58270, 58275, 58280, 58285, 58290-58294, 58541-58544, 58548, 58550, 58552-58554, 58570-58573), or a combined surgery (the NSQIP databased was queried for encounters that contained both a breast surgery code and hysterectomy procedure code). We then queried the database for SSI rates within 30 days of surgery. SSI rates were compared using a χ2 test with a nominal value of p < 0.05 as a test for significance. Results: We identified a total of 174,605 patients who underwent a breast surgery and found a SSI rate of 2.59%. We identified a total of 137,121 patients who underwent hysterectomy and found a SSI rate of 2.58%. We identified 383 patients who underwent a combined breast surgery and hysterectomy and found a SSI rate of 2.87%. When comparing SSI rates of combined breast surgery and hysterectomy, to breast surgery or hysterectomy alone, we found no significant difference in the rates of SSI between these groups (p = .7304). We analyzed SSI rates in patients by different surgical approaches including combined breast surgery and open hysterectomy and found an SSI rate of 4.35% (p = .357), combined breast surgery and laparoscopic hysterectomy and found an SSI rate of 2.38% (p = .931), and combined breast surgery and laparoscopic assisted vaginal hysterectomy and found an SSI rate of 2.75% (p = .916). Conclusions: The rates of SSI in patients undergoing combined breast surgery and hysterectomy is not significantly different from breast surgery or hysterectomy alone. Gynecologic oncologist should coordinate with breast surgeons to perform a combined procedure in patients who require both breast surgery and hysterectomy.

We present a novel, cost efficient two-phase design for predictive clinical gene expression studies: early marker panel determination (EMPD). In Phase-1, genome-wide microarrays are used only for a small number of individual patient samples. From this Phase-1 data a panel of marker genes is derived. In Phase-2, the expression values of these marker panel genes are measured for a large group of patients and a predictive classification model is learned from this data. Phase-2 does not require the use of expensive whole genome microarrays, thus making EMPD a cost efficient alternative for current trials. The expected performance loss of EMPD is compared to designs which use genome-wide microarrays for all patients. We also examine the trade-off between the number of patients included in Phase-1 and the number of marker genes required in Phase-2. By analysis of five published datasets we find that in Phase-1 already 16 patients per group are sufficient to determine a suitable marker panel of 10 genes, and that this early decision compromises the final performance only marginally.

Erythroid Progenitor

A two-phase liquid-culture system was used to substantially amplify and differentiate erythroblasts, starting with mononuclear cells from the blood of normal adults, newborn infants, and patients with sickle cell anemia. After the first 7 days (phase 1), in medium plus fetal bovine serum (FBS) alone, or in combination with stem cell factor (SCF) or conditioned medium (CM), the cell number was unchanged, and the cells all looked like lymphocytes. These cells were then diluted into medium with erythropoietin (Ep) alone, with Ep and either SCF or CM, or in methylcellulose with the same factors (phase 2). After 14 days in liquid phase 2 with SCF and Ep, the cell numbers increased an average of 30-fold in the sickle, 24-fold in the newborn, and 4-fold in the normal adult cultures; almost all the cells were erythroblasts and erythrocytes. SCF in phase 1 increased the number of late progenitors (CFU-E) assayed in methylcellulose, with the largest number in sickle, followed by newborn cultures and then adult cultures. We conclude that erythroid progenitor cells survive for at least 7 days without Ep (but with FBS). Progenitor cells are amplified, particularly with SCF. Later in culture, SCF with Ep increases the final number of differentiated erythroid cells. Both the early and the late effects of SCF are most effective in sickle, followed by newborn cultures and then adult cultures.
