A 55-year-old woman presented with symptoms of intractable nausea and vomiting, followed by headache and confusion two weeks after an elective laparoscopic vertical sleeve gastrectomy procedure. She had a presumed diagnosis of IIH and a remote history of CSF oto/rhinorrhea treated with a lumbar peritoneal (LP) shunt. Computed tomography (CT) scan of the head revealed tension pneumocephalus with midline shift and dehiscence of the tegmen. The patient underwent emergent craniotomy for decompression of the air-filled temporal lobe, clamping of the LP shunt, and repair of the skull base defect. Caution should be exercised in obese patients with a history of CSF leak secondary to a middle fossa skull base defect when being evaluated for bariatric surgery.

Performance problems cannot be solved by simply increasing operating frequency while relying on technology improvements for low power. Instead, DSP architectures need to be adapted specifically for low power operation. This paper proposed an architecture that relies on dynamic reconfiguration of hardware resources to implement low-power and programmable processors for DSP applications. This technique has shown to yield at least an order of magnitude of power reduction compared to traditional instruction-based engines for problems in the area of wireless communication.

It has drawn the attention of the researchers. The optical networks with the capacity of the order of Tbps are evolving. The capacity of individual optical channel is increasing towards 100 Gbps and beyond. In this paper, we demonstrate design and performance of 1.92 Tbps WDM Optical System. Three CW lasers are used to generate optical carriers. Twelve sub carriers, each spaced 80 GHz apart are produced using two dual tone generators. Each subcarrier carries information at transmission rate of 160 Gbps to enhance the spectral efficiency to 2 b/s/Hz. The analysis is carried out for 12 × 160 Gb/s (1.92 Tb/s) PDM-QPSK WDM optical system considering three different cases that is without coding, with gray coding and with differential coding for 100 km transmission distance. Extensive simulations are carried out to evaluate symbol error rate, error vector magnitude and Q-factor in each case. From the comparison, it is observed that the system with differential coding gives better performance in comparison with other two cases. An improvement in Q-factor with differential coding is achieved in the range of 2 to 5 dB with respect to other two cases. It is also shown that the transmission distance for PDM-QPSK WDM optical system with differential coding can be extended upto 8000 km keeping the Q factor above the FEC limit requirement (BER value 3.8 × 10-3).

Milkfat may promote the growth of microbes that are beneficial in long-term weight loss. Understanding the specific gut microbiome changes after surgery and their relationship to milkfat consumption may yield important strategies for managing obesity after bariatric procedures. Methods In this pilot study, stool samples were collected from nine patients before and at the time of surgery, and at 1, 3, and 6 months post-surgery. At each time-point, dairy consumption was determined from dietary surveys. 16 s rRNA gene sequencing was performed followed by alpha diversity analysis. Comparisons of relative abundances of microbial taxa and analyses of fatty acids changes were performed. Results Bariatric surgery led to enrichment of (i) Roseburia, associated with weight loss and (ii) Christensenellaceae, inversely related to body mass index. High milk-fat consumption correlated with enrichment of Blautia, inversely associated with visceral fat accumulation. Faecalibacterium, possibly associated with obesity, increased in patients with low milk-fat consumption. Butter was associated with decreased alpha diversity in all subjects (p-value = 0.038) and the frequency of its use was associated with decreased alpha diversity in patients (correlation = − 0.68, p-value = 0.042). Low-milk-fat consumers showed higher concentration of saturated fatty acids. Conclusions Our results suggest that incorporating dairy products in post-bariatric-surgery dietary plans may help cultivate a gut microbiome that is effective in regulating fat storage as well as digesting beneficial metabolites. These observations will be helpful for the management of obesity in general population as well.

A 55-year-old woman presented with symptoms of intractable nausea and vomiting, followed by headache and confusion two weeks after an elective laparoscopic vertical sleeve gastrectomy procedure. She had a presumed diagnosis of IIH and a remote history of CSF oto/rhinorrhea treated with a lumbar peritoneal (LP) shunt. Computed tomography (CT) scan of the head revealed tension pneumocephalus with midline shift and dehiscence of the tegmen. The patient underwent emergent craniotomy for decompression of the air-filled temporal lobe, clamping of the LP shunt, and repair of the skull base defect. Caution should be exercised in obese patients with a history of CSF leak secondary to a middle fossa skull base defect when being evaluated for bariatric surgery.

Milkfat may promote the growth of microbes that are beneficial in long-term weight loss. Understanding the specific gut microbiome changes after surgery and their relationship to milkfat consumption may yield important strategies for managing obesity after bariatric procedures. Methods In this pilot study, stool samples were collected from nine patients before and at the time of surgery, and at 1, 3, and 6 months post-surgery. At each time-point, dairy consumption was determined from dietary surveys. 16 s rRNA gene sequencing was performed followed by alpha diversity analysis. Comparisons of relative abundances of microbial taxa and analyses of fatty acids changes were performed. Results Bariatric surgery led to enrichment of (i) Roseburia, associated with weight loss and (ii) Christensenellaceae, inversely related to body mass index. High milk-fat consumption correlated with enrichment of Blautia, inversely associated with visceral fat accumulation. Faecalibacterium, possibly associated with obesity, increased in patients with low milk-fat consumption. Butter was associated with decreased alpha diversity in all subjects (p-value = 0.038) and the frequency of its use was associated with decreased alpha diversity in patients (correlation = − 0.68, p-value = 0.042). Low-milk-fat consumers showed higher concentration of saturated fatty acids. Conclusions Our results suggest that incorporating dairy products in post-bariatric-surgery dietary plans may help cultivate a gut microbiome that is effective in regulating fat storage as well as digesting beneficial metabolites. These observations will be helpful for the management of obesity in general population as well.
