Abstract
Aims Phenylketonuria and type 1 diabetes are lifelong metabolic disorders requiring complex and potentially conflicting nutritional strategies. Their coexistence is rare, yet management may become particularly challenging during transition from pediatric to adult care. We describe the case of a young adult with phenylketonuria who developed type 1 diabetes.
Methods A 27-year-old man with longstanding phenylketonuria was referred to an adult metabolic-diabetes center after the diagnosis of type 1 diabetes. Clinical, biochemical, nutritional, and continuous glucose monitoring data were reviewed. The intervention included structured therapeutic education, transition from fixed insulin doses to a dynamic regimen based on carbohydrate counting, and revision of medical nutrition therapy using phenylketonuria-adapted low-protein foods and sugar-free phenylalanine-free amino acid supplements.
Results At diagnosis, HbA1c was 11.5%, with markedly reduced C-peptide levels and high titer anti-GAD antibodies. Ini-tial diabetes management was associated with poor adherence to the phenylketonuria diet, increased intake of conventional protein sources, and elevated phenylalanine levels. After individualized insulin titration and nutritional intervention, HbA1c improved from 11.5% to 7.8%, phenylalanine levels decreased from 842 to 705 μmol/L, insulin requirement declined from 0.55 to 0.3 IU/kg/day, and continuous glucose monitoring showed improved glycemic control without increased hypoglyce-mia. The Glycemia Risk Index improved from high-risk Zone E to low-intermediate-risk Zone B.
Conclusions This case highlights the need for personalized multidisciplinary care integrating continuous glucose monitor-ing, carbohydrate counting, and phenylketonuria specific nutrition to optimize both metabolic conditions.

Context Advanced hybrid closed loop (AHCL) systems currently represent the most advanced modality of insulin therapy.
Aim To compare the night-time (from 00 to 07 a.m.) effectiveness in achieving recommended glycemic targets of three dif-ferent AHCL systems in adults with type 1 diabetes (T1D).
Methods We retrospectively evaluated 55 adults with T1D (mean age 41±16 years, male 40%, diabetes duration 19.4±11.4 years, BMI 24.1±4.1 kg/m2 ) with similar glycemic control (GMI 7.0–7.4%). Twenty-two participants were using the Minimed 780G system, 18 the Tandem t:slim X2 with Control-IQ system and 15 the DBLG1 system. Continuous glucose monitoring derived metrics and insulin requirement of 14 consecutive nights were
Results All three groups achieved the recommended mean TIR>70%, mean TBR<4%, and mean CV<36% with a similar insulin requirement (Minimed 780G system: TIR 73.9±11.2%, TBR 0.9±1.2%, CV 29±6.7%; Tandem t:slim X2 with Con-trol-IQ system: TIR 74.1±11.1%, TBR 1.1±1.0%, CV 34.5±6.6%; DBLG1 System TIR 71.7±11.3%, TBR 1.4±3.7%, CV 32.4±7.1%). Tight TIR% (70–140 mg/dl) was significantly higher (p<0.01) in the Tandem t:slim X2 with Control-IQ group (51.5±9.8%) when compared to Minimed 780G group (42.1±13.7%) and DBLG1 System (40.1±10.5%). In all three groups the insulin infusion similarly decreased from midnight to 05.00 am and then increased.
Conclusions All the three AHCL systems achieved the recommended TIR, TBR and CV without difference in insulin requirement. The Tandem Control-IQ system obtained a higher tight TIR.

糖尿病足的切口设计是糖尿病足局部脓肿及窦道治疗的第一步,也是最关键的一步之一,由于糖尿病足脓肿和窦道的多样性,以及糖尿病足病人全身情况的不一致,因此,要找到糖尿病足切口的设计规律比较困难,我们根据大量的临床实践,制定了以下的一些原则。
在上节中提到局部鉴别皮肤组织的“死活”是一个难题,有读者问有关在创面表面用“亚甲基蓝”染料染色来鉴别的问题,这种方法是一种比较古老的方法,对于相对较干净的伤口的效果比较好,对于严重感染的伤口容易出现误报,而且为了最大程度的保护足的结构和功能,一般采取蚕食性的方法进行清创,用这些染料染色后,反而有时候会干扰对肉芽组织生长的判断,容易造成清创过多的情况,因此,目前应用较少(也比较难得到有证书能够在临床应用的这种染料)。
针对“杨氏扩散”的特殊性、沿着窦道扩散的缺点及足部手术的原则,我们设计了一种沿着窦道行纵向切开的“刘氏切法”(图1),特点是:(1)沿着窦道做平行于足纵轴切开;(2)一般在窦道开口及窦道末端切开;(3)切口长度3-4CM;(4)足弓部足底边缘部的切口非常关键。
