Highly dispersive optical solitons in birefringent fibers with four nonlinear forms using Kudryashov’s approach
This paper exhibits bright, dark, singular as well as combo optical highly dispersive solitons in birefringent fibers. The governing model is considered with four forms of nonlinear refractive index. The existence criteria for such solitons are also listed.

Renal impairment in multiple myeloma : a single center experience
To determine the features of the different forms of kidney diseases associated with
multiple myeloma (MM), we retrospectively studied 144 patients with kidney injury and MM at
our institute from 1974 to 2014. The mean age of the patients was 60.1 years and the male:female
ratio was 1.25. Renal disease was concomitant with the discovery of MM in 92% of cases. The
mean follow-up of our patients was 2.1 years. Initial renal insufficiency was found in 131 (91%)
patients. Cast nephropathy of the distal tubule was found in 110 (26%) patients, renal amyloidosis
in 16 (11.1%), and light chain deposition disease in five (3.47%). Twelve (8.3%) patients had
chronic glomerular nephropathy. Twenty-six patients reached end-stage renal failure within 13.4
months. Renal survival was 30.45 months. Predictive factors for improvement of renal function
undergoing chemotherapy included serum creatinine <250 μmol/L, proteinuria <1 g/24 h, and the
non-use of renal replacement therapy. Multiple pathogenic mechanisms can contribute to kidney
injury in myeloma patients. Novel myeloma agents have shown considerable promise in reversing
renal failure in some patients and improving outcomes.

Clinical outcomes of acute kidney injury patients treated in a single-center, Sub-Urban Satellite Hospital
Acute kidney injury (AKI) is a common diagnosis among critically ill patients.
Although the etiology of AKI will determine the appropriate initial management, the definitive
management of established AKI is still debatable. This is a retrospective, observational, single-center
analysis of a cohort of patients referred to the nephrology unit for AKI from 1st August 2010 to 31st
January 2011. Those patients with indications for dialysis were treated with continuous renal
replacement therapy, intermittent hemodialysis or stiff-catheter peritoneal dialysis as determined by
their hemodynamic status and the technical availability of the method. The 30-day mortality rate, renal
outcomes and independent prognostic factors were analyzed statistically. Seventy-five patients were
reviewed. The mean age was 52.9 ± 14.5 years. Two-thirds were males and 75% were Malays. 53.3%
were referred from intensive wards. Pre-renal AKI and intra-renal AKI were diagnosed in 21.3% and
73.3% patients, respectively. Sepsis was the most common cause (n = 59). The pathogens were
successfully cultured in 42.3% of the cases. The median urea and creatinine were 30.4 [interquartile
range (IQR) 20.3] mmol/L and 474 (IQR 398.0) μmol/L, respectively. Seventy-six percent had
metabolic acidosis. Oliguria was only noted in 38.7% of the patients. Sixty percent (n = 45) of the
referrals were treated with conventional, intermittent hemodialysis and 22.7% (n = 17) with continuous
veno-venous hemofiltration. The 30-day mortality rate was 28%, and was higher in intensive wards
(37.5% versus 17.1%). Thirty-one percent (n = 20) had complete recovery, 17 (26.6%) had partial
recovery without dialysis and seven (10.9%) became dialysis dependent. The 30-day mortality rate
was 28%. Referral from intensive wards was the only significant poor prognostic factor in our patients
and not the dialysis modalities.
